A Rare Complication after Tricuspid Annuloplasty / 日本心臓血管外科学会雑誌

ABSTRACT

We report a rare case of severe aortic regurgitation after mitral valve replacement (MVR) and tricuspid annuloplasty (TAP). An 83-year-old woman underwent MVR and TAP for mitral regurgitation and secondary tricuspid regurgitation. The early postoperative course was not eventful until 6 days after surgery. However, 7 days after surgery, she suffered from acute heart failure and transthoracic echocardiography showed severe aortic regurgitation. We performed a second operation 13 days after the first surgery. Intraoperatively, we found the annulus suture of the TAP just under the NCC-RCC commissure of the aortic valve. We speculated that the suture pulled the aortic valve annulus, resulting in severe aortic regurgitation. We removed the suture and replaced the aortic valve with bioprosthetic artificial valve. Postoperative recovery was uneventful, and she was discharged 22 days after the second surgical procedure.
