Is a new end-aortic balloon catheter safe and feasible for minimally invasive cardiac surgery?
A newly developed 11Fr end-aortic balloon catheter appears feasible and safe for aortic occlusion and cardioplegia delivery during minimally invasive cardiac surgery in a small initial case series.
May support feasibility in small series; leaves open need for prospective trials before wider adoption.
Recently minimally invasive surgery with many innovative techniques has been developed to provide patients the benefits such as decreased pain and quick recovery from surgical insult. Purpose: The goal this study is to develop the end-aortic balloon catheter which occludes the ascending aorta without the need for an external cross clamp, vents the aortic root, enables delivery of antegrade cardioplegia. It is safe and easy to use during MICS. Methods: The catheter consists of a balloon and three lumens for monitoring the systemic and balloon pressures and for cardioplegia infusion. The catheter is flexible 11Fr. size in diameter and can be inserted from the ascending aorta. This small catheter with peripheral CPB allows for minimal incision and maximum visualization. Clinical Use: We used this end-aortic balloon catheter in four clinical open-heart surgery, 3 cases in ASD, and one in mitral valve repair. Results: The balloon inserted from the ascending aorta assures ideal positioning and stability for optimal cardiac venting and cardioplegia delivery. There is no worry of ischemia in the legs. All 4 patients discharged the hospital within 4 POD. All patients were satisfied with quick recovery and return to work. Conclusion: These results demonstrate that this new end-aortic balloon catheter is feasible, safe, easy to use and effective for minimally invasive surgery.

Yozu et al. (2000) conducted a case report in Minimally invasive cardiac surgery (n=4). End-aortic balloon catheter was evaluated on Hospital discharge within 4 postoperative days. A new end-aortic balloon catheter was successfully used in 4 minimally invasive cardiac surgeries, with all patients discharged within 4 days postoperatively.
