概要 A 72-year-old female with idiopathic dilated cardiomyopathy underwent a generator exchange for a cardiac resynchronization therapy defibrillator with a full-pocket capsulectomy. The lead position after the operation was identical to that before the operation on the chest X-ray. After 4 months, a subacute exacerbation of her heart failure was caused by cardiac resynchronization therapy failure due to a dislodgement of the left ventricular lead. An aggressive adhesiotomy of the connective tissue around the leads made it possible for the lead to retract by a ratchet-like movement through the suture sleeve, so-called "ratchet syndrome", after the generator exchange.
