Blood cysts of the heart valves are commonly reported at postmortem examination of infants but are rare seen in older children and adults. A 42-year-old woman was referred to our hospital for cardiac evaluation because of dyspnea on exertion and heart murmur. There was no history of cyanosis or cardiac failure. Cardiac catheterization revealed valvular pulmonary stenosis and atrial septal defect. Right ventricular angiography showed the circular filling defect 0.7 x 0.7 cm in size at the suprapulmonary valve. However, this preoperative abnormal finding was diagnosed as a blood cyst after surgery. At operation a blood cyst originating from the right cusp of the pulmonary valve was found and resected, and was followed by commissurotomy of the pulmonary valve and direct closure of the atrial septal defect. Her postoperative course was uneventful.
心脏瓣膜血囊肿在婴儿尸检中常见，但在大龄儿童和成人中罕见。一名42岁女性因劳力性呼吸困难和心脏杂音转诊至我院进行心脏评估。既往无发绀或心力衰竭病史。心导管检查显示瓣膜性肺动脉狭窄和房间隔缺损。右心室造影显示肺动脉瓣上有一个大小为0.7×0.7 cm的圆形充盈缺损。然而，术后该术前异常发现被诊断为血囊肿。手术中发现一个起源于肺动脉瓣右瓣叶的血囊肿并将其切除，随后进行肺动脉瓣交界切开术并直接闭合房间隔缺损。她术后恢复顺利。
