A patient developed perioperative coronary artery spasms (CAS) twice, in initial and redo open heart operations for mitral stenosis. CAS was shown by sudden ST segment elevation, hypotension, bradycardia, and decreased cardiac output. The patient, a female, had the first CAS attack in the ICU following open mitral commissurotomy at the age of 48. The Second CAS attack occurred during redo surgery for mitral valve replacement at age of 56. Preoperative coronary angiography before both operations did not indicate significant organic lesions. Intraaortic balloon pumping in conjunction with intravenous nitroglycerin and norepinephrine were effective to treat CAS in this case.
