Geoffrey Oliver Hartzler, MD, passed away suddenly in his home at the Lake of the Ozarks on March, 10, 2012. Family, friends, and medical and business colleagues will remember Dr. Hartzler as a generous and caring man who was as humble as he was brilliant. Funeral: 11:30 a.m. Friday in Greenwood Chapel, Fort Worth, TX. A memorial service will follow in Kansas City, on a date to be determined. Interment: Greenwood Memorial Park. Visitation: 6- 8 p.m, Thursday at Greenwood Funeral Home. Memorials: In honor of his courageous battle against prostate cancer, gifts in Geoffrey's memory can be sent to the Prostate Cancer Foundation at or the American Heart Association at Pallbearers: Greg Hartzler, Ronnie Cooper, Wayne Cooper, Steven Bodie Cooper, Lew Wagner, and Zach Shafran. In his lifetime, Dr. Hartzler was revered as a pioneer in the field of interventional cardiology. In 1981, he became the first physician to use percutaneous transluminal coronary angioplasty (PTCA) to treat heart attack. Despite intense criticism and skepticism, Dr. Hartzler was able to refine and defend the procedure, finally establishing direct angioplasty as the preferred standard of care worldwide, saving millions of lives. He performed the first PTCA to treat multiple vessel disease. He created the first implantable defibrillator to reach the market and be used effectively. He was also instrumental in developing the first steerable guidewire catheters and went on to help design a family of "Hartzler" balloon catheters used in angioplasty. Dr. Hartzler possessed enormous energy, intense concentration, and unparalleled technical skills. He worked hard to offer better results and more efficient care to patients. His commitment to teaching and research was legendary. He created the first database aggregating outcomes data of tens of thousands of patients. He began the first U.S. interventional cardiology teaching course, training a generation of cardiologists. In 1986, he developed the Advanced Angioplasty Fellowship training program, which has been emulated world round. After cutting back his clinical practice in 1993, Dr. Hartzler pursued his many business interests ranging from radar technology to medical devices. Yet, he remained a prominent figure in the international cardiology community. He took on the directorship of the Mid America Heart Institute at St. Luke's Hospital in Kansas City, where he had been on staff as a Consulting Cardiologist since 1980. He continued to publish in peer review journals, and travel to conferences around the world. He appeared in Who's Who in America in 1998, has been the subject of numerous interviews and articles, and has received more awards than he would want to admit. His contributions to the advancement of angioplasty and cardiology are recognized annually through the "Geoffrey O. Hartzler Master Clinical Operator Award" given by the Society for Cardiovascular Angiography and Interventions. Dr. Hartzler's achievements and accolades could fill volumes, but he, more than any, would have hated the idea. He revolutionized cardiac medicine in the face of initial scrutiny and criticism, and yet, he was a humble man. He was kind and always curious and interested in those around him. Family, friends, and even acquaintances felt that he was a blessing, the one person they could truly count on for help if needed. He relished a quiet life with his wife and the affection of his daughters and close friends. For many years, he and Dorothy often retreated to their house at the Lake of the Ozarks. His brother Greg remembers that even while blowing up stumps with homemade explosives and getting into other sorts of mischief as young man, Geoffrey was always helping people. As a young cardiologist (and an old one!) Geoffrey enjoyed fast cars and motorcycles, wearing cowboy boots to work, and mastering new technology. He loved music and was a talented bass guitar player. In fact, his brother Greg has said that he always thinks of Geoffrey as a musician first. As a young man, Geoffrey was a member of several popular jazz and rock n' roll bands that performed in the area around his northern Indiana hometown of Goshen. In recent years, his Kansas City band, "Heart Rock," performed and cut several CDs. Geoff had fun mixing their recordings, as well as jamming with other musician friends. He was born Nov. 6, 1946, in Goshen, Ind. He had two brothers, one deceased as a teenager. His father Robert was a Mennonite minister who helped establish the first outpatient community mental health center in the United States. His mother Emma contracted polio when Geoffrey was four years old. She lived in an iron lung for nearly four decades. Geoffrey's Mennonite upbringing deeply informed his perspective on life. A quotation he particularly liked is by Benjamin Whicote: "Our fallibility and the shortness of our knowledge should make us peaceable and gentle." Geoffrey was certainly both. Survivors: Geoffrey is survived by Dorothy, his wife of 27 years; brother, Gregory; daughters, Abby, Christine, Amanda, and Angela; and grandsons, Jonah and Oliver. He will be sorely missed. Arrangements: Greenwood Funeral Home, 3100 White Settlement Rd., Ft. Worth, TX  817-336-0584

I first met Geoff in February 1983 in the early angioplasty days. I was blessed to be able to work with him both in the Cath Lab and as a partner in business. In those days, there were no Interventional Cardiologists that would attempt complex multi-vessel cases but he did with phenomenal success. He was always humble about his work and never bragged about his patient successes. While working with him in the Lab, I noticed how he was respected by all that worked with him and how he respected them. He was a class act to work with.

As a business partner, he was always willing to help in any way. His focus was on better patient care first. He used his intelligence, knowledge and wisdom when dealing with business associates. I spent time travelling with Geoff on business trips and got to learn a lot about his childhood in Goshen, Indiana. From those discussions, I felt a lot of his qualities came from his bringing up and early experiences in Goshen.
He had several big health problems, e.g. his back, which caused him a lot of continuous pain but he never complained and would press on through the pain.

He was multi-talented in many ways, e.g. with his band called HeartRock and his recording studio called The Warehouse where he produced his many CDs. His recording studio had all the electronics and computer gear needed to produce his CDs. Of course, he was very proficient in using all of the sophisticated equipment. I have barely touched the surface on his many talents.

I miss him as a friend and look forward to when I will see him again in heaven.

Born with WPW, Dr Hartzler did my first EPS in 1980 ... God bless him ... May our Lord continue to comfort his family ... Know that after all these years I still am blessed not only by his medical care, but his sincere compassion for those he cared for ...

I was Geoff's secretary for about 7-1/2 years back in the 1980's. I did a lot of typing including slides for his presentations. He inspired me so much, he totally changed my direction in life. I was so proud to work for him. I did not know he passed until today, Oct 29, 2013. He would always say how buried he was under all the cans of film he had yet to see, to give his opinion on a patient's arteries. One day, I drew a picture of Geoff, buried under a mountain of film cans. He left me a note the next day saying that I obviously needed more work to do! He affected me in a way that made me so aware of what I did, especially concerning helping people. It was the most enjoyable job I ever had.

I learned of Geoff's untimely passing today from a mutual friend. I first met Geoff at TCT in his role as Chairman of IntraLuminal Therapeutics, and again as Chair of Cardiovascular Systems. Our relationship grew into a friendship, and I never failed to be energized and uplifted by his business acumen, clinical knowledge, wise counsel, sharp wit, and gentle humanity. What a blessing he must have been to his patients. I didn't know about his musical interests until recently and will go back and listen to my "Heart Rock" CD. Our family extends condolences and prayers to his family. I will truly miss Geoff.

First, I want to express my sincere sympathy to Dorothy, Abby, Chrissy, Amanda and Angela. The loss you are feeling is shared by those of us who worked with him and admired him so. It has taken me this long to be able to put my thoughts together regarding my years of working with Dr. Hartzler. I went to work for him on December 18, 1986, and worked with him until his retirement in December of 1995. What exciting years those were!! He truly was a "MASTER" in his field - but he never sought praise or special recognition; instead he downplayed his many successes. I loved the words of Dr. Giorgi - Dr. Hartzler really "was an uncommon man who was at home with common people". On many occasions I urged him to write a book on how to work with people. He demanded no more from his employees than he was willing to give of himself. Everyone who worked with him loved him and were inspired to do their very best to please him. He was the ideal "Boss". I count the years I had the privilege of working with Dr. Hartzler as the experience of a lifetime. Going to work everyday was a joy - very exciting. He put Saint Luke's Hospital and the Mid America Heart Institute on the national and international map. He is now and forever will be greatly missed.

My prayers go out to Geoff's family. Geoff meant and gave so much to so many people. His gifted mind, hands, and engineering saved and extended so many lives. His gift of music enlightened many. His leadership, patience and teachings is the reason why so many of us in the cardiology field survived and succeeded. Thanks for everything Dr. Geoffery Hartzler..You will be dearly missed and never be forgotten.

It was a great pleasure to work with Dr Hartzler starting in 1985 in the Cath Lab as a Tech. 27 years later I still continue your work at a single Cath Lab taking care of patients and teaching Fellows. I am very proud to say that I learned from one of the greatest teachers I've ever known. I will always be eternally grateful and cherish every moment spent working beside one of the greatest Cardiologists ever. My thoughts and prayers are with Dr. Hartzler's family.

My condolences to Dr. Hartzler's family. I am so grateful that I was able to work in the cath lab at SLH when he was working in the forefront of interventions. He was truly amazing! He had the respect of all because of his warm personality and gifted hands. When he would walk into the lab everyone would stop because we all knew what he had to say was so important. His patients were so comforted and reassured when he would speak with them. He truly put them at such ease before the procedure. I am so thankful that I was able to learn so much during those days in the cath lab. Dr. Hartzler will truly be missed.

To Dr Hartzler's family:
I was quit saddened to hear of Geoff' death. I met him when I first joined the staff here in Kansas City at St. Luke's Hospital in 1995. He was a giant of his field, bringing to mind the quote from Sir Isaac Newton, who revised older similar quotes, to say, "If I have seen further, it is by standing on the shoulders of Giants." Geoffrey Hartzler was a giant in the world of interventional cardiology who has helped others "see further" (and he wasn't a bad musician, either). He was a kind and welcoming soul who has done much to improve the care of patients with cardiovascular disease. He was already missed here at St. Luke's Hospital since his premature need to retire, and now he will be missed furthermore. May his family find comfort from the sincere words of kind remembrance from his circle of friends and associates.

Geoff was one of the nicest and most human of physcians I have ever known. He was a brillant cardiologist and pioneered multivessel angioplasty.
Geoff started and helped many companies in the cardiovasculr field. He was literally able to drive the market in this reguard.
I know how much he cared for his wife and family . I know we all have trials in this life. I know Geoff was able to manage these trial with great fineese.
I am proud to have been a friend of Geoffs and am sad at his passing. I want to celebrate the greatness and gentleness of the human being.I hope we can all strive to celebrate his life.
A truely great man

I started working in the CCL at SLH in 1986 to get out of RT. Who knew I would be working with such a brilliant as well as compasionate man as Dr. Hartzler! Twenty six years later, I am still a cath tech and will always remember him saying "Somebody go help that girl". Truly a remarkable man.

I worked as a nurse at St. Luke's in the 1980s. Dr. Hartzler was a great man and doctor. I was so impressed by how he truly cared for each one of his patients. He always, without fail and no matter how tired he was, visited his patients the night before a procedure and the evening after their procedure. His bedside manner was reassuring to his patients. He was also very kind to all of the nursing staff. I was honored to care for his patients. He will be missed.

Dr. Hartzler was a wonderful man that I had the opportunity to know and work with for over 20 years. In the early days of PTCA, I worked to develop balloon catheters that bore his name at ACS. Then I had the tremendous fortune to work directly with him at IntraLuminal. It was because of his vision and leadership that I joined the IntraLuminal team. He will be missed. My prayers to his family.

It is because of Geoff's skill and diligence that I am alive today. He did my 1st PCTA in early Feb. 1981. Changed me from unstable angina to out jogging in a week. He recently, Nov 2011, still remembered me and which artery(s) he opened. A great pioneer but more a grat man. The world will be less without him.

It was such an exceptional opportunity to meet Dr. Hartzler when I worked in the CCU at St. Luke's Hospital during the early 1990's. Having moved from Dallas, it was impressive to be working with such a skilled and innovative cardiologist. Many lives have been saved because of Dr. Hartzler's touch. Throughout my days at Cardiovascular Consultants, I have so enjoyed all the shared stories of his magnificent life. Our prayers are with his family.

Clinically, 1993 was the best year of my life. Lee Bailey and myself were "Hartzler's last fellows." I feel truly blessed not only to have learned my art from "the master" but to have also experienced his intensity and humor in the lab and the compassion, respect, empathy and unpretentious way he treated each of his patients and their families. I left my fellowship in Kansas City for a job in South Bend/Elkhart, IN, just a few miles from where Geoff grew up in Goshen. I have often felt a higher source was using me to complete the circle of care Geoff started. We are all deeply saddened by the news. I felt empty today but took solace in the fact that Geoff lives on in my heart and mind, as he does in all of his previous fellows, colleagues and friends. My heartfelt condolences to his family.

In 1981 I moved to Kansas City and was looking for a Cardiovascular Care Unit. I had worked in one in Springfield and was looking for a CCU. The day of my interview I met Dr. Hartzler and he spoke to me about the work being done at SLH and encouraged me to join their team. He is a legacy and taught me so much and I had the privledge to return to my first hospital and tell of them the amazing and innovative work of Dr. Hartzler. His pioneer attitude moved though out the hospital and I now work in Saint Luke's Neuroscience Institute. Our team has been able to also be pioneers in the field, but I have often spoke and given credit to Dr. Hartzler for his work in the coronary arteries which has extended to the cerebral arteries. My prayers are with your family and know that he impacted my career in nursing.

Around the world there are hundreds of thousands of people who owe their lives to Geoffrey Hartzler. His intuition and his pursuit of what was considered to be a crazy idea, expanding a balloon in an artery that was infarcting, created what is today the gold standard for the treatment of heart attack. His procedure stops the heart attack in its tracks, saving the heart muscle, often the patient's life, and allowing that patient to continue a full and productive life. He truly revolutionized cardiology. And he was a really nice guy, too! We will all miss him terribly.

Dr. Hartzler was one of the greatest Cardiologist of all times. It was a priveledge to work with him for many years at the Mid America Heart Institute. There is no way to describe the training that we received in his room. He was amazing to watch. He talked very softly but his message was so important. Doctor's from all over the world would come to observe his work. It was a pleasure and an honor to work by his side and share the wonderful experiences with him. His talent and friendship will never be forgotten. He will be in our hearts forever. Thank you Dr. Hartzler. Our thoughts and prayers are with his family and to you Dorothy.

We lost a truly great man! I met Geoff the week he was cleaning out his MAHI office to “retire.” I was pitching a dissertation idea to study stress and depression in heart patients and was surprised at how interested he became in my ideas and in me as a person. We bonded over music (the Heart Rock band and our Friday afternoon jam sessions including a CD we made) and discussions about life. A few stories about Geoff….
**I had invited Geoff to my graduation party and he said he couldn't make it but was quick to offer to take me to lunch the day after. He also asked if I had time to help HIM pick out a new guitar. We went to a great music store and he had me play quite a few and then asked which one I liked the best. He bought the guitar and a nice amp. When we got back to my truck he asked me to carry/roll the amp and he grabbed the guitar. He put the guitar in the back of my truck and asked me to load up the amp up too. “Congratulations Chris, I'm really proud of you! Enjoy your graduation presents.” I was speechless and got pretty choked up. All I could do was thank him and give him a big hug. I always like when people ask me about that guitar…because it's a story about Geoff.
**I was a day or two away from moving to San Diego and wanted to ship my old computer to my sister. I was quite frustrated as I was having trouble getting a laplink program to work and it would take hours to manually transfer all my files to my new computer. Geoff called and I told him what I was doing. He said “I bet I can get that to work for you.” I resisted his offer since I knew he had been having back pain and at that point I didn't even have any furniture in the house—just a computer sitting on a wood floor. He came over, sat on the floor and yes….got the laplink program to work. This past Christmas eve I called a friend to wish him Merry Christmas. He mentioned that he was going to be hosting a Christmas eve dinner in a few hours, but that his bathroom was leaking and dripping down on his dining room table. I thought about Geoff…..and this story from 12 years ago….and I rushed to Home Depot and then to my friend's house and fixed his plumbing. (Hopefully the metaphor of fixing plumbing and Geoff's profession is not lost on any of you! Geoff would laugh at this!). That's the effect of Geoff on my life!
There are plenty more stories to share….Geoff was a walking lesson in how to make people feel special!
I asked Geoff if he had a favorite song that really moved him, made him dance or jam along with on his bass guitar. “What'd I Say” by Ray Charles he answered. So whenever I'd hear that song it was a prompt to call Geoff. Once when I called he was in the theatre watching “The Bucket List”—a movie he really liked and recommended. We have both seen the movie several times and it often came up in our conversations. A few months ago I asked him what was on his bucket list. Geoff said “Nothing man, I've done it all!” That's the hallmark of a man who artfully lived a full life. Geoff is well-loved and will be greatly missed… and he will rest in peace!

My prayers and condolences go out to Dorothy and Geoff's family. As a young nurse in the MICU at Saint Luke's in the early 1980's, I feel honored and privileged to have worked with such a humble, gentle man during such an exciting time for interventional cardiology. Although he was creating an international stir in the cardiology arena, he was able to make each patient feel like they were the only thing he was concerned about at the moment. We often did not know he had come into the ICU in the middle of the night until the monitor alarms went off. He was testing the bedside ICD but hadn't told us! He left an amazing legacy not only professionally but personally and I am grateful to have been a part of that. Thanks for sharing him with us.

My sincere condolences to Dr. Hartzler's family. Besides my respect, I owe Geof my gratitude for standing by my side as we performed the first two angioplasties in Lincoln,NE in 1981. Not without having to overcome some adversity, the procedures with his encouragement and advice were accomplished and launched a very successful interventional program.

Geoff relentlessly pushed the frontiers of interventional cardiology on a worldwide stage, yet never lost his compassion for each individual patient's well-being. It was an honor and great fortune to have walked beside him as a colleague and good friend. He will be dearly missed, and our prayers are with Dorothy and her family.

Throughout my whole career as an interventional cardiologists, I hear Geoff's soft, succinct voice in my head. He had a way of making the focus intimate in the tension of the cath lab. As we worked, we became the artery, equipment and the patient. I was blessed with incredible good fortune as a young fellow to find myself in a position to help and observe the beginning of Geoff's revolution in treating heart attack victims. His trust and confidence in me was the foundation for my career. As I continue to treat acute heart attack victims, I still hear Geoff's soft voice in my ear as I face the challenges and it comforts and motivates me. Geoff made a monumental difference during his life. There is no greater thing we can do then save someone's life and Geoff is responsible for saving the lives of literally millions with the procedure he pioneered with the support of Barry and Dave and his colleagues. Dottie, I share some of your grief and thank you for our time together when I was a fellow.

Geoff has been riding on my shoulder, whispering into my ear my whole career. That soft, succinct, voice, that was quite intimate in the setting of cath lab tension will always be with me. I never take for granted the awe and wonder of acute MI intervention after training with Geoff and his trust and confidence in me, to let me be a part of something at the beginning, that truly saved countless lives, when I was a young fellow. Dottie, I share some of your grief and thank you for being part of my life when I was a fellow.

Our thoughts and prayers are with you and your famly. Geoff touched each of our lives in a profound way...saving Gene's life with acute intervention, and his undying support during my career with Cardiovascular Consultants. He taught both of us more about life and health than we can express. What a remarkable man, and what a privilege to have shared in his world. Dottie, we hope you know how you were loved and appreciated as his life partner!

I also grew up with Geoff in Goshen, Indiana. He certainly made all of us very proud to have known him. May God bring his family peace at this difficult time.

It is difficult to add to what's been said. Like Jim Vacek, I had the pleasure and privilege of knowing Geoff through music. I can tell you that his many former colleagues here in Rochester Minnesota, remembering his warmth as a person and his genius as a physician, mourn as I do. Rest in peace, Geoff.

My time with Geoff what as the beginning of my interventional career but was the best year a young man could ever dream of. The interview was bold, assured me I would be side by side, hands on hands, not wasting time. And hold, on, what a year of watching a man with a 3D brain like no others, hands like no others, patient respect and love like no other. I am so grateful that we kept a friendship since 1990 and I visited him last year and took him to lunch at the Capital Grille. I am proud to have written his biography, though that was a battle to get a humble man to agree. I spoke to him just a few weeks ago, so upbeat, so excited about Ollie and his kids and bride. We have lost so much, I have lost a friend, my love and condolences to Dotty and family

I started my career at the Mid America Heart Institute in 1984. Geoff was in the earlier days of developing what would become standard treatment of heart attacks everywhere, and I still consider it my greatest honor to have been a small part of that program. Geoff was a genius at what he did, and a true friend and colleague to the technical staff at the Heart Institute. I miss his humor and his wisdom. May God receive him, and support his family in this time.

There are men with great vision and there are men with an overwhelming desire to implement and make vision reality. Geoff was both. I remember Geoff and Dr. Greunzig arguing as we built a temporary cath lab until we finished the Mid America Heart Institute. Dr. G was saying that this was good enough until the entire project was complete. Geoff was resolute and we did it his way. It turned out to be decision that propelled Saint Luke's while others were waiting. We, in the Saint Luke's community will miss Geoff but we will never forget him.

Geoffrey was a lightening rod changing the face of cardiology forever. He was also a generous, compassionate doctor who gave of his soul to his patients and their families. It is such a memorable delight to have had the opportunity to work with Geoff and to know him personally. His bright light will shine on for eternity. My thoughts are with Dorothy and his family.

Geoff was a truly great man, a pioneer and innovator in medicine, a true and devoted friend, a remarkably talented musician, a kind and generous spirit. His passing is an immeasurable loss to his family, friends, and the medical profession. He changed the field of interventional cardiology and bettered the care of patients with heart disease worldwide. A gifted visionary, he was a tireless inpiration, teacher, and mentor to generations of cardiologists.
He was one of the best friends I have ever had and I will miss him very much.
