Dextrocardia is a rare cardiac malposition that was first described in 1606. Mirror-image dextrocardia is characterized by a mirror-image change of the normal position of the heart. Most cases are accompanied by situs inversus viscerum, whereas only 3% to 10% of cases are associated with intracardiac anomalies. Valve surgery for acquired valvular lesions in patients with mirror-image dextrocardia with situs inversus is rare. Diagnosing situs anomalies in adults is important to prevent errors during surgical operations, emergency procedures, or interventional operations. In this report, we present two cases of mitral regurgitation in patients with mirror-image dextrocardia. One patient had mirror-image dextrocardia with subacute infective endocarditis and mitral regurgitation, and the other patient had mirror-image dextrocardia with mitral Carpentier type I regurgitation. In both patients, mitral valve repair was successfully performed using a transseptal approach.
右位心是一种罕见的心脏位置异常，于 1606 年首次描述。镜像右位心的特征是心脏正常位置的镜像变化。大多数病例伴有内脏逆位，但只有 3%至 10%的病例伴有心内畸形。对于镜像右位心伴内脏逆位的获得性瓣膜病变患者，瓣膜手术很少见。在成人中诊断 situs 异常对于防止手术、急诊程序或介入操作期间的错误很重要。在本报告中，我们介绍了 2 例镜像右位心伴二尖瓣反流的病例。1 例患者为镜像右位心合并亚急性感染性心内膜炎和二尖瓣反流，另 1 例患者为镜像右位心伴二尖瓣 Carpentier Ⅰ型反流。在这 2 例患者中，均采用经房间隔途径成功进行了二尖瓣修复。
