Exercise-induced syncope as late consequence of radiotherapy.
This report describes a 34-year-old female with an exercise-induced atrioventricular block resulting from transient ischemia caused by a radiation-induced ostial stenosis of the right coronary artery. Patient first underwent coronary artery surgery with a right internal mammary artery to the right coronary artery. After 18 months she was readmitted with exercise-induced syncope due to graft occlusion. This time a successful rotablator procedure was performed on the ostial stenosis.
