Exercise‐induced ventricular arrhythmia due to bilateral coronary to pulmonary artery fistulas

Ischemic polymorphic ventricular ectopy was documented during exercise testing in a 65‐year‐old Caucasian male patient. Coronary angiogram revealed four coronary to pulmonary artery fistulas (CPAFs) originating from the right and left coronary artery, leading to myocardial ischemia due to steal phenomenon. The three dominant fistulas were coiled percutaneously, while one small fistula was left untreated. During follow‐up, no significant residual ventricular arrhythmia was detected.
