An isolated fistula between the right pulmonary artery and the right pulmonary vein: An unusual cause of stroke in a young female

Abstract

We describe the case of a 29 year-old female who presented with right sided hemiparesis with global aphasia. She had a history of transient ischemic attack with migraine headaches. Diagnostic workup revealed a right to left cardiac shunt. An isolated right pulmonary artery to left pulmonary vein fistula was diagnosed on pulmonary angiogram. The fistula was occluded successfully by cardiac catheterization. Early recognition and intervention is indicated to prevent further complications. (Cardiol J 2011; 18, 1: 73-76)
