Abstract

A 33-year-old female with recurrent syncope episodes showed normal ECG and Holter results, but had mitral valve prolapse (MVP) with moderate mitral regurgitation (MR) on an echocardiogram. Cardiovascular magnetic resonance (CMR) revealed mitral annulus disjunction (MAD) with fibrosis. She received an implantable loop recorder (ILR). Several months later, she experienced a syncope event, which correlated with self-terminating polymorphic ventricular tachycardia (PMVT) preceded by narrow complex tachycardia, which was proven to be atrioventricular nodal reentrant tachycardia (AVNRT) in an electrophysiology study. Post-ablation, she had no recurrences of syncope. This case highlights the importance of ILR in avoiding unnecessary ICDs in MVP patients with syncope.

二尖瓣脱垂伴晕厥:不要以貌取人!
一名 33 岁女性反复晕厥发作,心电图和 Holter 结果显示正常,但超声心动图显示二尖瓣脱垂(MVP)伴中度二尖瓣反流(MR)。心血管磁共振(CMR)显示二尖瓣瓣环脱节(MAD)并伴有纤维化。她接受了植入式环路记录器(ILR)。几个月后,她经历了一次晕厥,晕厥与自终末多形性室性心动过速(PMVT)有关,之前是窄复律心动过速,电生理学研究证实这是房室结性返流性心动过速(AVNRT)。消融术后,她没有再出现晕厥。该病例强调了 ILR 在避免晕厥 MVP 患者不必要使用 ICD 方面的重要性。
