A man with double inlet left ventricle and severe subpulmonary stenosis underwent a Fontan operation at the age of 29 years. Eight years later he developed atrial flutter with complete heart block. To avoid a further thoracotomy, a unipolar carbon tipped electrode was placed into the posterior cardiac vein via the coronary sinus. More than 8 years after implantation of the original lead, and after two generator changes, telemetric thresholds remain between 1.8-2.1 volts. Percutaneous transvenous ventricular pacing via the coronary sinus can produce an excellent long-term result and should be the initial approach of choice after a Fontan-type operation.
一名患有双入口左心室和严重肺瓣下狭窄的男子在29岁时接受了Fontan手术。八年后，他出现了伴有完全性心脏传导阻滞的心房扑动。为避免再次开胸手术，通过冠状窦将单极碳尖电极置入心脏后静脉。在最初的导线植入超过8年后，并且在更换了两个起搏器之后，遥测阈值仍保持在1.8 - 2.1伏之间。经冠状窦进行经皮经静脉心室起搏可产生出色的长期效果，应作为Fontan型手术后的首选初始方法。
