Distortion of the left anterior descending coronary artery after pulmonary valve replacement.

Injury of the left main coronary artery may sometimes complicate a pulmonary valve replacement (PVR). We present the case of a 39-year-old man, with post-operative distortion of the left anterior descending coronary artery, which caused onset of ventricular arrhythmia associated with electrocardiographic signs of myocardial ischemia. A coronary angiogram revealed the cause of the lesion. Stenting the coronary artery restored normal coronary blood flow and improved the patient's condition. Through this case, we describe a new life-threatening complication after PVR. © 2015 Wiley Periodicals, Inc.
