Key result
Gap-filler aortic valve closure achieves ~41 minutes shorter cross-clamp time vs sandwich technique during LVAD.
Why the study?
Mechanical aortic valve management during LVAD support remains challenging, and long-term durability data for novel closure techniques are needed.
Does the novel gap-filler technique improve structural outcomes and reduce cross-clamp time compared to the conventional sandwich technique for mechanical aortic valve closure during LVAD support?

Absolute Event Rate: 28% vs 69%
A novel gap-filler technique for mechanical aortic valve closure during LVAD support showed reduced cross-clamp time and excellent long-term structural durability compared to the conventional sandwich technique in a case report.
May shorten aortic cross-clamp time in LVAD patients; hypothesis-generating for durable mechanical aortic valve closure versus sandwich technique.
Mechanical aortic valve management during left ventricular assist device (LVAD) support remains challenging. Herein, we report a novel mechanical aortic valve closure technique and its structural outcomes after >6 years of LVAD support. Compared with the conventional sandwich technique, the gap-filler technique required a shorter aortic cross-clamp time (28 vs. 69 min) and demonstrated complete structural integrity at heart explantation without patch dislocation or gross thrombus formation, suggesting superior long-term durability.

Shiozaki et al. (2026) conducted a case report in Left ventricular assist device (LVAD) support with mechanical aortic valve. Gap-filler technique for mechanical aortic valve closure vs. Conventional sandwich technique was evaluated on Aortic cross-clamp time. The gap-filler technique for mechanical aortic valve closure during LVAD support required a shorter aortic cross-clamp time (28 vs. 69 min) compared with the conventional sandwich technique.
