title: Mechanical reperfusion of acute right coronary artery occlusion after radiofrequency catheter ablation and long-term follow-up angiography.
abstract: Coronary artery injury is a rare complication of radiofrequency catheter ablation. We describe the case of a 12-year-old girl who had an acute distal right coronary artery (RCA) occlusion during radiofrequency catheter ablation of a postero-septal accessory pathway treated with mechanical reperfusion utilizing an angioplasty guidewire. Coronary angiography performed at 1-year follow-up depicted normal left ventricular function, patent descending posterior artery and total occlusion of the postero-lateral branch, which was filled through a rich collateral circulation from the RCA marginal branch.
