A 74-year-old woman, with a history of aortic valve replacement and open mitral commissurotomy due to rheumatic aortic and mitral stenosis, presented with dyspnea. She developed severe tricuspid regurgitation (TR), requiring tricuspid valve replacement (TVR). Despite an uneventful postoperative course, she was readmitted for dyspnea 2 months later. Trans-thoracic echocardiogram revealed severe mitral regurgitation (MR), despite mild MR at the time of TVR, which has not been previously reported. The main MR mechanism was increased left ventricular preload due to improved TR. Increased diuresis has controlled her congestive heart failure, but her MR remained moderate.
一位 74 岁女性,因风湿性主动脉瓣和二尖瓣狭窄而行主动脉瓣置换和二尖瓣交界切开术,出现呼吸困难。她发展为严重的三尖瓣反流(TR),需要进行三尖瓣置换(TVR)。尽管术后过程顺利,但 2 个月后她因呼吸困难再次入院。经胸超声心动图显示严重二尖瓣反流(MR),尽管在 TVR 时 MR 较轻,但此前并未报道过这种情况。主要的 MR 机制是由于 TR 改善导致左心室前负荷增加。增加利尿治疗已控制了她的充血性心力衰竭,但她的 MR 仍为中度。
