Left ventricular pacing via the coronary sinus is being increasingly used. There is little data to guide possible lead extractions that might be required in the future. Significant adhesions to the coronary veins were found 12 years after placing a pacing lead in the posterolateral coronary vein in a man with double inlet left ventricle and severe subpulmonary stenosis who had undergone a Fontan operation. The appearances suggest that percutaneous extraction from the proximal coronary sinus may be feasible but that difficulty may be encountered if the lead tip is placed into the distal coronary veins.
经冠状窦进行左心室起搏的应用越来越广泛。目前几乎没有数据可用于指导未来可能需要的导线拔除。在一名患有左心室双入口和严重肺下狭窄且已接受Fontan手术的男性患者中，将起搏导线置于后外侧冠状静脉12年后，发现其与冠状静脉存在明显粘连。这些表现提示，从冠状窦近端进行经皮拔除可能可行，但如果导线尖端置于冠状静脉远端，则可能会遇到困难。
