May offer bailout option for refractory LV summit PVCs; leaves open need for prospective validation.
A 60-year-old man with premature ventricular contraction (PVC) - induced cardiomyopathy arising from the left ventricular summit (LVS) failed endocardial ablation. Successful elimination was ultimately achieved using targeted ethanol infusion through hypoplastic great cardiac vein (GCV).
