Abstract
Coronary Artery Disease (CAD) and acute coronary syndrome (ACS) are the most common cause of poor quality of life and death worldwide.
Assessment of the patency of the graft is a highly recommended procedure. The incidence of intraoperative failure of the graft is estimated to be around 5% for internal mammary artery grafts. However, the incidence of failure of venous grafts is estimated to be as high as 11%. Accordingly, the EACTS has recommended routine intraoperative verification of graft patency as class IIa recommendation.
This study aimed to elaborate a new method for detection of coronary artery bypass graft patency by endovascular visual verification of anastomotic points and its promising outcomes on myocardial revascularization.
The study included 40 patients who presented with CAD and are candidates for coronary artery disease undergoing coronary artery bypass grafting (CABG). The efficacy of endovascular visualization was correlated with TTFM during CABG and positive correlation was detected, the in vitro part allowed us to perform anastomoses resembling the coronary anastomosis performed in real life. We have chosen to use the descending thoracic aorta of rabbits and correlate the visual score to fluoroscopic score. There are no issues with the safety of this technique. Since the scope is inserted under vision and uses saline irrigation to avoid touching the vessel walls, it is even safer than coronary probes.
