Pulmonary valve replacement (PVR) is the most common adult congenital cardiac operation performed. Valve degeneration leading to prosthetic stenosis and/or regurgitation is a long-term risk in this population and may be associated with paravalvular leak (PVL). Complications involving the proximal pulmonary artery, including dissection, are less clearly defined. Herein, we report the case of a 30-year-old patient with a history of multiple pulmonary valve interventions secondary to congenital pulmonic stenosis, who developed dehiscence of a bioprosthetic PVR associated with significant paravalvular leak (PVL) and further complicated by a focal dissection of the proximal pulmonary artery.
肺动脉瓣置换术（PVR）是最常见的成人先天性心脏手术。瓣膜退变导致人工瓣膜狭窄和/或反流是该人群的长期风险，可能与瓣周漏（PVL）有关。涉及近端肺动脉的并发症，包括夹层，定义尚不清楚。在此，我们报告一例30岁患者，有先天性肺动脉狭窄继发多次肺动脉瓣干预病史，发生生物瓣PVR裂开，伴有严重瓣周漏（PVL），并因近端肺动脉局灶性夹层而进一步复杂化。
