An advantage of bioprosthetic mitral valve replacement in patients with normal sinus rhythm is avoidance of the need for long-term anticoagulation. Bioprosthetic valve thrombosis is a rare complication, supporting this approach. This case report represents an example of porcine mitral valve stenosis, likely secondary to thrombosis, in which all of the native mitral valve apparatus was left intact. This was successfully treated with standard anticoagulation therapy. This complication should be considered in patients in whom retention of the mitral valve apparatus has been performed. Such patients may benefit from long-term anticoagulation treatment to obviate this event.
对于窦性心律正常的患者，生物人工二尖瓣置换术的一个优点是无需长期抗凝。生物人工瓣膜血栓形成是一种罕见的并发症，支持了这种方法。本病例报告展示了一例可能继发于血栓形成的猪二尖瓣狭窄病例，其中所有天然二尖瓣装置均保持完整。该病例通过标准抗凝治疗成功治愈。对于保留二尖瓣装置的患者，应考虑这种并发症。此类患者可能受益于长期抗凝治疗以避免发生这种情况。
