Outline of Final Research Achievements

Atheroembolism is a major concern for patients undergoing cardiovascular surgery because prevalence of diabetes and obesity is increasing in recent several decades. In aged patients, athrosclerotic change of the aorta may induce embolism of the atheromatous debris in the aortic wall when instrumentation of the aorta is performed. The purpose of this study is to develop less invasive technique to avoid detachment of the debris from the arctic wall during operation.
We developed a less invasive system to connect side branch on the ascending aorta without touching the diseased aorta. This system is consisted of the connecting device and aortic cutter without interruption of the aortic flow during operation. Side-clamp of the aorta is also unnecessary. Therefore, risk of atheromebolism is minimum if this system is used.
