Abstract
We reported here on 2 cases of aortic regurgitation (AR) that were due to avulsion of the aortic valve commissure. Aortic valvuloplasty was attempted in both cases. In the 1st case, valvuloplasty was performed with reattaching the commissure using the 5-0 polypropylene continuous suture technique. However, aortic regurgitation recurred and this lead to reoperation on the postoperative $14^{th}$ day. The intraoperative finding revealed a completely re-detached commissure that required mechanical valve replacement. In the second case, we attempted to reattach the commissure using pledgetted multiple transverse mattress sutures with 5-0 polypropylene. Because the leaflet coaptation was incomplete, the aortic valve was replaced with a tissue valve.
