Abstract

We present a patient with a history of a Sorin tilting disc prosthetic mitral valve implanted 20 years ago who developed acute dyspnoea. Echocardiogram revealed a unique pattern of 'obstruction alternans' of mitral valve prosthesis due to pannus formation. We emphasize the need for urgent surgical treatment of this potentially fatal complication.

摘要

我们报告一名患者，其20年前植入了索林倾斜盘式人工二尖瓣，现出现急性呼吸困难。超声心动图显示，由于 pannus 形成，二尖瓣假体出现了一种独特的“梗阻交替征”模式。我们强调，对于这种可能致命的并发症，需要紧急进行手术治疗。
