Coronary Artery Bypass Grafting in a Patient with Severe Left Ventricular Dysfunction and Enlargement, Showing Clinical Features of Ischemic Cardiomyopathy / 日本心臓血管外科学会雑誌

ABSTRACT

Ischemic cardiomyopathy with a severe left ventricular dysfunction and enlargement, is a dismal prognosis, but can be a surgical candidate. So, differential diagnosis of ischemic cardiomyopathy from other cardiomyopathies and evaluation of myocardial viability are important. We successfully performed coronary artery bypass in a 68-year-old patient with ischemic cardiomyopathy. His preoperative left ventricular function showed an end-diastolic volume of 281.8cc/M/m², pressure of 30mmHg, and ejection fraction of 13.1%. We conclude that coronary artery revascularization provides significant benefits for ischemic cardiomyopathy with reversible myocardial ischemia.
