About us

Prof. Juergen Ennker is a specialist in surgery, thoracic and cardiovascular surgery, cardiac surgery and vascular surgery. He has around 35 years experience in procedures on the heart and the great blood vessels – as Director, he has been responsible for over 28,000 procedures; he has performed around 10,000 procedures himself. Since 2004, an independent portal comparing physicians has recommended Prof. Ennker as an outstanding heart specialist. His medical emphases are in the treatment of congenital cardiac defects and cardiac tumors, as well as in procedures on the great cardiac vessels. Here, whenever possible, he relies on gentler, minimal invasive techniques.

For Prof. Ennker, the health and wellbeing of his patients come first. So, he is one of the first cardiac surgeons in Germany who, around 20 years ago, performed the first procedures on the heart without a heart-lung machine. This is possible for patients with coronary heart disease, which is frequently treated with bypass surgery. The use of a heart-lung machine enables the heart to be immobilized during surgery. This procedure, however, is associated with a longer regeneration phase for the patient.
Procedures on the cardiac valves cannot be performed on the beating heart and so here, the heart-lung machine cannot be dispensed with. But here, too, Prof. Ennker possesses outstanding competence: He has developed the world’s largest range of biological aortic valve procedures. In order to make the quality and the transparency of his work comparable, Prof. Ennker takes the approach of making his figures and reports for his procedures available to the public on the Internet.

Along with his practical surgery activities, Prof. Ennker is also highly regarded for his scientific research. As a Professor and a Visiting Professor, he holds numerous teaching events at a variety of universities, publishes hundreds of contributions in specialist scientific publications, he is the author and coauthor of a large number of textbooks and gives countless, sometimes later published, presentations at national and international specialist conferences.

Prof. Ennker is the Principal Physician of the Department of Cardiac Surgery and Near-heart Vascular Surgery at the Helios Hospital, Krefeld.
