Key result
Cutting balloon venoplasty successfully relieved a localized vein stenosis after standard balloons failed, enabling the placement of a coronary sinus lead for left ventricular pacing.
Why the study?
Does cutting balloon angioplasty enable successful left ventricular pacing lead placement in patients with refractory coronary vein stenosis?
Does cutting balloon angioplasty enable successful left ventricular pacing lead placement in patients with refractory coronary vein stenosis?
Cutting balloon angioplasty can be an effective technique to overcome refractory coronary vein stenosis and facilitate left ventricular pacing lead implantation.
May aid LV lead placement after standard venoplasty failure; hypothesis-generating and should not yet change practice.
We describe a patient in whom a localized proximal vein stenosis at the only possible target vein precluded placement of a coronary sinus lead for left ventricular (LV) pacing. After multiple attempts to perform venoplasty with both compliant and noncompliant balloons, a cutting balloon relieved the obstruction, and an LV pacing lead was successfully placed in the midportion of this lateral vein.
