The authors report the experience with the methodological implantation of thermo-coronary-angiography in the Division of Cardiovascular Surgery of the Hospital de Clínicas, Federal University of Paraná, and the Hospital Universitário Evangélico de Curitiba. It is a totally noninvasive technique that allows the real time assessment of the coronary blood flow with no interruption on the surgical procedure. Using TCA, it was possible to analyze the heart before and after the bypass graft completion, which allowed the visualization and recording of the ischemic area in the myocardial wall, the assessment of the graft patency, including stenoses, and the status of myocardial perfusion by preestablished collateral branches. Therefore, TCA is helpful in order to improve the results of the coronary artery bypass graft surgery, providing a higher treatment quality to the patient with coronary artery disease. Due to its great number of advantages, this infrared imaging method has an enormous likelihood to become a crucial tool to perform a safe myocardial revascularization. Further more, a permanent TCA system established in the operating room would extend all its benefits to other cardiac surgical procedures.
