Key result
Venoplasty with a noncompliant balloon successfully treated a resistant coronary vein stenosis that was unresponsive to standard compliant balloon dilatation during CRT device implantation.
Case Report (n=1)
Venoplasty with a noncompliant balloon can successfully treat resistant coronary vein stenosis during CRT device implantation when standard compliant balloons fail.

May facilitate CRT in resistant venous stenosis after compliant balloon failure; hypothesis-generating case report requiring validation.
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.

CHAUHAN et al. (2008) conducted a case report in Resistant coronary vein stenosis during cardiac resynchronization therapy (n=1). Venoplasty with noncompliant balloon vs. Standard compliant balloon dilatation was evaluated on Successful treatment of stenosis. Venoplasty with a noncompliant balloon successfully treated a resistant coronary vein stenosis that was unresponsive to standard compliant balloon dilatation during CRT device implantation.
