Key result
Coronary venous angioplasty can be safely and easily performed to enable left ventricular lead passage beyond a stenosis during cardiac resynchronization therapy.
Why the study?
Does coronary venous angioplasty facilitate left ventricular lead placement in patients with coronary venous stenosis?
Does coronary venous angioplasty facilitate left ventricular lead placement in patients with coronary venous stenosis?
Coronary venous angioplasty is a feasible technique to overcome coronary venous stenosis and facilitate optimal left ventricular lead placement during CRT implantation.
May aid select CRT cases with venous stenosis; leaves open need for prospective studies before practice change.
Coronary venous stenosis is an uncommon finding in patients referred for cardiac resynchronization therapy device implantation. Nonetheless, it may result in suboptimal lead positioning for chronic left ventricular (LV) pacing. Coronary venous angioplasty is a technique that can be performed relatively easily and safely to enable LV lead passage beyond a stenosis.
