Intraoperative thermal coronary angiography: quality control

Abstract

Per operative coronary angiography has always been desired by coronary surgeons. Direct coronary angiographic imaging is not practical since needs contrast injection requires radiation and excessive technology with experienced staff which adds more expenses. Thermal angiography device IVA-2000 (OPGAL) is started to be used in our coronary bypass operations as a routine procedure. Thermal imaging provides an effective and real time coronary angiograms which provides very clear coronary angiograms as well as graft flows. The temperature differences generated in between the myocardium and the coronary arteries by injecting cold cardioplegic solution into the proximal end of the vein graft or by warm blood running through an internal thoracic artery graft creates an angiographic image and provides graft flow with termodilution technique after cross clamp released. Thermal images provided with thermal camera easy to tax no need for extra staff no side effects of contrast media to the patients and no radiation effect to the theatre stuff also. We will demonstrate basic principal of thermal camera and thermal coronary angiograms of different patients with different aspects.
