[Coronary Artery Bypass Grafting and Biventricular Pacing for Severe Heart Failure due to Dilated Cardiomyopathy].
A 57-year-old man was diagnosed with dilated cardiomyopathy and coronary stenosis. His electrocardiogram showed a complete left bundle branch block and a prolonged QRS interval. As appropriate medical therapy improved his symptoms, he did not visit out-patient clinic after discharge. A year later, he presented with exertional chest oppression and was readmitted with severe heart failure. Although medical therapy was provided, his condition did not improve. Left ventricular systolic dysfunction and stenosis of the left anterior descending artery were aggravated. We performed coronary artery bypass grafting and biventricular pacing with surgical epicardial leads, which led to improvement in left ventricular systolic function. We consider that biventricular pacing with surgical epicardial leads is a potential option in cases of open heart surgery requiring cardiac resynchronization therapy for severe left ventricular systolic dysfunction.
