The diagnostic method of choice to proof coronary artery disease and to localize stenoses and to judge the stage of the disease is coronary angiography. A new angiographic technique invented by. Wolffgram and Krieter that works without cannulation of the coronary arteries could simplify the interventional procedure. In addition, a technique like this could be used for angiography after CABG surgery directly on the table for quality assurance reasons. This angiography could be performed by the cardiac surgeon without necessarily involving a cardiologist. A feasibility study was successfully done in a cooperation of the Departments. for Cardiology and Cardiac Surgery, Munich University, Steinbeis Transfer Centre for rHealthcare Technologies, Tuebingen and Fraunhofer Technology Development Group (TEG), Stuttgart.
