[Coronary Artery Bypass Grafting (CABG) and simultaneous cardiac resynchronization therapy in a patient with left...

Noncompaction of the left ventricular myocardium (NCLV) is a rare congenital cardiomyopathy resulting from an arrest in normal endomyocardial embryogenesis, and has been known as a disease of infants. However, some cases of NCLV in adults have been recently reported. We experienced an adult NCLV case repeating heart failure, and controlled it by surgery. The patient was 75-year-old man with NCLV and he had repeated heart failure and hospitalization. His heart failure had been barely control by infusion of human atrial natriuretic peptide (hANP). Coronary angiography revealed double vessel disease( #2 100%, #6 90).We performed coronary artery bypass grafting(CABG) with intraoperative cardiac resynchronization therapy. The heart failure was dramatically improved and the patient was discharged on foot 32 days after operation. However, careful observation of cardiac function is vital because of the possibility of progression to heart failure of NCLV.
