In a 60-year-old woman with long-standing angina left heart catheterisation revealed peripheral and central coronary arteriovenous fistulae connected to the left and right coronary system and opening into the pulmonary artery. The fistulae connected to terminal coronary artery branches were corrected by ligation of these feeding arteries while the electrocardiogram was continuously monitored. The central fistulae were closed via a transcoronary approach of the left anterior descending artery. Knowledge of different surgical techniques helps to prevent perioperative myocardial infarction and late fistula recurrence.
