Specialist in internal medicine, cardiology, sports medicine and cardiovascular intervention.
Following studies in medicine at the University of Freiburg, internships in Boston (USA), Marseille (France), and residencies in Munich (Germany), Prof. Ischinger relocated to Emory University in Atlanta with the support of a Fulbright Scholarship for specialized training in invasive cardiology (heart catheterization and angiography) and interventional cardiology (coronary angioplasty) with the pioneer in the field Prof. Dr. Andreas Grüntzig, with whom he collaborated clinically and scientifically from 1981 to 1983. From there, Prof. Ischinger accepted a position as director of Interventional Cardiology at the St. Louis University School of Medicine. In 1984 he returned to the Heart Center Bogenhausen in Munich. He earned board certification in internal medicine and cardiology and a Ph. D. degree in 1986. In 1990 Prof. Ischinger was appointed university professor at the University of Erlangen-Nürnberg. Until 2010 and prior to founding KIZ – Kardiologie im Zentrum – Prof. Ischinger continued to hold the position as senior associate at Bogenhausen Heart Center, responsible for interventional cardiovascular techniques and innovative therapeutic concepts.
Prof. Ischinger is married and father of two adult daughters.
Prof. Ischinger is considered a co-pioneer in the development of interventional cardiology (minimally invasive heart catheter interventions) and one of the most experienced interventional cardiologists in the world. He contributed significantly to the introduction of coronary angioplasty into clinical routine in the early 1980s in the United States. Since then, Prof. Ischinger has gathered extraordinary practical experience with all available methods. He has personally completed over 10,000 cardiovascular interventions and accompanied many more in a responsible role. Innovative procedures in particular are part of his repertoire:
- Balloon angioplasty for vascular stenoses (percutaneous angioplasty (PTA)) and percutaneous coronary angioplasty PTCA
- Stent implantation (e.g. coronary stent, carotid stent, aortic stent)
- Implantation of closure devices (umbrella closure) for septal defects, e.g. ASD closures (for atrium septum defects) or PFO closures (for open foramen ovale)
- Valvuloplasty (balloon angioplasty for stenotic heart valves)
- Minimally invasive implantation of biological heart valves (percutaneous aortic valve replacement)
The following disorders are treated by minimal invasive catheter techniques:
- Coronary heart disease (CHD), imminent and acute myocardial infarction
- Peripheral arterial occlusion (pAVK), e.g. arteries of the upper ond lower extremities and iliac arteries
- Stenosis of the carotid artery (carotid stenosis), stenosis of other vessels that supply blood to the brain, imminent stroke
- Stenosis of kidney arteries (renal artery stenosis)
- Disease of the aorta, e.g. aortic aneurysma, aortic dissection (thoracis and abdominal aorta)
Prof. Ischinger is considered expert in all interventional and surgical therapies available today for treating cardiovascular disorders. His expertise is in demand around the world. His advice is sought as second opinion prior to cardiac or vascular operations or prior to minimally invasive treatments for selection of the optimal therapeutic option (differential therapy) in complex cardiovascular disorders. In addition, his personal network is often used to identify qualified specialists and treatment centers both in Germany and internationally.
Prof. Ischinger has continuously supported his clinical work with clinical research. Since 1982, numerous publications have featured his work in the areas of coronary heart disease, interventional cardiology, innovative catheter techniques, anti-thrombotic drug therapies, follow-up care after interventions, as well as prevention (primary prevention and secondary prevention).
Prof. Ischinger is author and publisher of text books, including the first reference book on coronary angioplasty (balloon dilation, PTCA) in 1986. In addition, he is author of numerous patient information and educational booklets (including an instructional video) on catheter interventions for the heart and the vascular system (e.g., Thieme Compliance Verlag). Prof. Ischinger is an editorial and review board member for national and international professional journals, committee member of scientific and professional societies in Germany and the United States, member of expert panels, scientific advisory board member for the Deutsche Herzstiftung, and faculty member of international conferences, including TCT in the United States, MEET in France, and GW-ICC in China among others.
He is a contributor to all important national and international professional conferences, including the annual conventions of the Deutsche Gesellschaft für Kardiologie, European Heart Society, American Heart Association, Asian professional associations, and TCT (Transcatheter Cardiovascular Therapeutics).
As one of the foremost experts in interventional cardiology, Prof. Ischinger has conducted live teaching seminars in Germany (Heart Center Bogenhausen) and Asia (Beijing) with broadcast from the heart catheterization laboratory. Today, cardiologists from around the world frequently attend his interventions to learn from his experience.
