【摘要】Background Cardiac resynchronization therapy (CRT) device and coronary sinus (CS) lead extraction are required due to the occurrence of systemic infection,malfunction,or upgrade.Relevant research of CS lead extraction is rare,especially in developing countries because of the high cost and lack of specialized tools.We aimed to evaluate percutaneous extraction of CS leads by modified conventional techniques.Methods Of 200 patients referred for lead extraction from January 2007 to June 2011,24 (12.0％) involved CS leads (24 CS leads).We prospectively analyzed clinical characteristics,optimized extraction techniques and feasibility of extraction.Results Complete procedural success was achieved in 23 patients (95.8％),and the clinical success in 24 patients (100.0％).The leading indication for CS lead extraction was infection (66.7％).Mean implant duration was (29.5±20.2)months (range,3-78 months).Sixteen CS leads (66.6％) were removed with locking stylets plus manual traction by superior transvenous approach.Mechanical dilatation and counter-traction was
