Blood cysts of the mitral valve are rare in adults. These blood cysts are often asymptomatic. Blood cysts resulting in severe left ventricular outflow tract obstruction leading to syncope have not been previously report. We report an adult who developed frequent syncope due to mitral valve blood cysts occluding the aortic orifice. This condition was detected by transthoracic and contrast echocardiography. The blood cysts were successfully removed. A pathological examination confirmed the diagnosis of blood cysts. Contrast echocardiography is a useful diagnostic modality for assessing cardiac blood cysts. This technique can play the same role as magnetic resonance imaging (MRI) in hospitals without MRI or in cases where MRI is not acceptable in an emergency.
二尖瓣血囊肿在成人中较为罕见。这些血囊肿通常无症状。此前尚未有因血囊肿导致严重左心室流出道梗阻并引发晕厥的报道。我们报告了一名成年人，其因二尖瓣血囊肿阻塞主动脉口而频繁发生晕厥。这种情况通过经胸和造影超声心动图得以检测。血囊肿被成功切除。病理检查确诊为血囊肿。造影超声心动图是评估心脏血囊肿的一种有用的诊断方法。在没有磁共振成像（MRI）设备的医院或紧急情况下MRI不可用时，该技术可发挥与MRI相同的作用。
