Abstract
Ventricular tachycardia due to occlusive engagement of right coronary artery by different types of coronary catheters have been known. The authors describe here a case of ventricular tachycardia occurring when a stent was being positioned in the proximal right coronary artery after uneventful engagement of a right coronary ostium by a Judkins 6F Guide. It is presumed that direct stent placement across the lesion without predilating the lesion could have caused occlusion of the right coronary artery lumen with consequent myocardial hypoxia and ventricular arrhythmia.
