Distal branch of septal perforator is the target to cannulate (arrow). Middle panel: left coronary angiography with 1 guidewire inside the first and 1 guidewire inside the second perforator (arrow). Lower panel: angiography after ethanol injection. A distal branch (arrow) of the second perforator is occluded. A: Injection of iced saline. Fast VT with disappearance of VT, after 30 seconds. B: Injection of ethanol. Single premature ventricular contraction, with no VT afterward. C: Final result. Complete eradication of VT and premature ventricular contraction after a couple of minutes. VT = ventricular tachycardia.
