Focused force coronary venoplasty to eliminate a refractory stenosis preventing LV lead placement in two patients

This report describes two patients who underwent a second attempt at cardiac resynchronization therapy (CRT) in the setting of a severe stenosis in the lateral coronary vein that prevented passage of a left ventricular lead. Both stenoses were unresponsive to standard noncompliant balloon dilatation but were successfully treated with the addition of a second stiff angioplasty wire beside the noncompliant balloon. Venoplasty with the addition of a side wire beside the balloon should be considered for resistant coronary vein stenosis encountered during CRT device implantation.
