title: Coronary vein angioplasty with noncompliant balloon for resistant coronary vein stenosis during left ventricular lead implantation.
abstract: This report describes a patient who underwent cardiac resynchronization therapy (CRT) in the setting of a severe stenosis in the lateral coronary vein that prevented passage of a left ventricular lead. The stenosis was unresponsive to standard compliant balloon dilatation but was successfully treated with a noncompliant balloon. Venoplasty with noncompliant balloon should be considered for resistant coronary vein stenosis encountered during CRT device implantation.
