Biography

Georg M. Wieselthaler, M.D. is a heart transplant surgeon and one of the world´s leading experts in  mechanical circulatory support for end stage heart failure patients. A Professor of Surgery at UCSF and Director & Surgical Chief of Cardiac Transplantation and Mechanical Circulatory Support, Dr. Wieselthaler has performed  more than 350 heart transplants and developed extensive expertise in the implantation of numerous types of ventricular assist device (VAD) systems at the Medical University of Vienna.

Dr. Wieselthaler graduated with a degree in electrical engineering from the College for Electrical Engineering in Vienna, Austria and received his M.D. as well from the University of Vienna, Austria. He did his residency and surgical training at the 2nd Department of Surgery, University of Vienna and received advanced training in transplantation in the Vienna Heart Transplant Program and Vienna Lung Transplant Program. He also completed advanced fellowships as staff surgeon at the Dept. of Cardiac Surgery in St. Pölten Hospital, Austria.

Dr. Wieselthaler has published numerous articles in peer-reviewed journals and has trained surgeons worldwide in implantation techniques and the use of varied   pulsatile and continuous flow ventricular assist devices. He is member of numerous national and international medical scientific societies and is President-Elect of the International Society for Rotary Blood Pumps.

He is also a  member of the Board of the European Society for Artificial Organs and Past President of the Austrian Society for Implantology and Tissue integrated Protetics. In April 2011, Dr. Wieselthaler was named Director of the International Society for Heart and Lung Transplantation. He is a frequent speaker and has served as chair for numerous national and international scientific conferences devoted to mechanical circulatory support and transplantation.

Research Overview

In 1984, while still in medical school, Dr. Wieselthaler became involved in the Ventricular Assist Device (VAD) Program  at the University of Vienna  and began working in the Biomedical Laboratory on the development of the driving unit for the "New Vienna Total Artificial Heart (TAH)". After graduation, Dr. Wieselthaler became aware of the advantages of rotary blood pumps and organized the world´s the first "International Workshop(s) on Rotary Blood Pumps" in the years 1988 and 1991 in Austria. Out of these meetings, the International Society for Rotary Blood Pumps was founded in 1992 with Dr. Wieselthaler acting as Secretary General for the organization for many years.

Dr. Wieselthaler and colleague Dr. Heinrich Schima, a biomedical engineer, then investigated and developed miniaturized centrifugal pumps over15 years in the Biomedical Laboratories of the University of Vienna. Dr. Wieselthaler thereafter became primary surgeon at the Medical University of Vienna where implanted various types of VAD systems and supervised patient care. He developed extensive expertise with pulsatile systems like Novacor LVAS and has had one of the longest supported patients on the device (over 4 1/2  years). He also developed the Thoratec paracorporeal and implantable VADs. One of his patients was supported more than 3 years on the world´s first full implantable VAD in the Arrow LionHeart CUPS Trial.

In 1998, Dr. Wieselthaler implanted the world's first implantable, miniaturized axial flow pumps, the MicroMed-DeBakey VAD and he has since implanted more than 80 patients with this device. Many of Dr. Wieselthaler´s leading scientific papers originated his early experience with the world´s first nonpulsatile pump, articles still cited by colleagues. Dr. Wieselthaler also served as  Principal Investigator and implanted the world´s first implantable, magnetically suspended centrifugal left ventricular assist device (LVAD), the "TERUMO DuraHeart LVAD".

In 2003, Dr. Wieselthaler joined a HeartWare Inc, Miramar, FL as a consultant and over the next three years, played a key role in the development the HeartWare HVAD, a miniaturized hydromagnatically levitated centrifugal pump. and in 2006, he implanted the world's first patients with this system.

Dr. Wieselthaler continued working with HeartWare on the next generation LVAD, known as the "Miniaturised Ventricular Assist Device (MVAD)", leading to two patent applications in his name for the technology: 1) a minimally invasive implantation technique of the MVAD, and 2) a special shaped inflow cannula tip for the MVAD.
