A 62-year-old woman undergoing redo mitral valve replacement was noted to have persistent intracardiac air following standard deairing procedures. Transesophageal echocardiography (TEE) identified air bubbles entering the left atrium from the right superior pulmonary vein. Exploration of the pleural cavity revealed a fistula between the pulmonary parenchyma and the right superior pulmonary vein caused by the atriotomy closure suture transfixing the edge of the lung, which was repaired with immediate disappearance of the air emboli. This demonstrates that transesophageal echocardiography is an invaluable aid to ensuring complete deairing after open heart procedures.
一名62岁接受再次二尖瓣置换术的女性在标准排气程序后仍有持续的心内气体。经食管超声心动图（TEE）显示气泡从右上肺静脉进入左心房。胸膜腔探查发现肺实质与右上肺静脉之间存在瘘管，是由心房切开术闭合缝线穿透肺边缘所致，修复后空气栓子立即消失。这表明经食管超声心动图对于确保心脏直视手术后完全排气是一项非常有价值的辅助手段。
