Immediate balloon inflation during ventricular fibrillation complicating coronary angioplasty — an alternative technique to angioplasty system withdrawal: Case reports and review

Two patients are presented in whom ventricular fibrillation occurred during otherwise uncomplicated percutaneous transluminal coronary angioplasty. Rather than withdrawing the angioplasty dilatation system in place in the coronary vessel before instituting resuscitation procedures, immediate balloon inflation was performed while a defibrillator was charged. During balloon inflation, both patients were countershocked, and they recovered stable cardiac rhythm. Postresuscitation hemodynamic and angiographic analysis revealed successful angioplasty results. This report describes an alternative technique to immediate removal of the balloon dilatation system for cardiac arrest complicating coronary angioplasty. Theoretical advantages and potential disadvantages of this technique are discussed.
