Abstract:
Mitral valve repair is becoming an increasingly frequent surgery for patients with mitral valve regurgitation. Iatrogenic coronary artery injury and ischemic myocardial compromise have been previously reported in the literature as a rare but serious complication of surgical mitral valve repair. This potentially life-threatening complication should be considered and quickly recognized during perioperative mitral valve repair or replacement to prevent morbidity and mortality. To increase awareness and to prevent this complication from being missed in the future, we present a case report of iatrogenic left circumflex artery dynamic occlusion and subsequent myocardial infarction from mitral valve annuloplasty resulting in severe peri-operative heart failure and death.
