Key result
A new Direct Endo Aortic Clamp balloon was successfully used in seven limited access cardiac surgery cases, with all patients discharged within 5 postoperative days.
Case Report (n=7)
A newly developed direct endo aortic occlusion balloon inserted into the ascending aorta was successfully used in 7 minimally invasive cardiac surgery cases, avoiding the need for lower limb arterial access.
May support direct endo-aortic clamping feasibility in limited-access cases; leaves open safety and efficacy in larger prospective studies.
In recent years, minimally invasive cardiac surgery (MICS), or limited access cardiac surgery, has been presented as a promising operative procedure. We developed a new balloon device that is inserted directly into the ascending aorta to stop the heart during limited access cardiac surgery. The balloon has a three lumen structure: balloon lumen port, cardioplegia/vent lumen port, and aortic root lumen port. This direct EAC balloon catheter, designed to be inserted directly into the ascending aorta, is different from the Heartport system. The Heartport EAC balloon catheter is inserted into the aorta via an artery in the lower limb, making lower limb arterial disease a key concern. Our Direct Endo Aortic Clamp (EAC) balloon overcomes this problem. The device was clinically used in seven cardiac cases. All patients were discharged within 5 postoperative days, confirming the utility of the device.

Yozu et al. (2001) conducted a case report in limited access cardiac surgery (n=7). Direct Endo Aortic Clamp (EAC) balloon was evaluated on discharge within 5 postoperative days. A new Direct Endo Aortic Clamp balloon was successfully used in seven limited access cardiac surgery cases, with all patients discharged within 5 postoperative days.
