Abstract
BackgroundHypertrophic cardiomyopathy is a commonly inherited heart disease. In addition, single coronary artery (SCA) is a rarecongenital anomaly of the coronary arteries. And SCA concomitant with severehypertrophic obstructive cardiomyopathy (HOCM) has seldombeen reported in the literature. However, such caseshave not been reported to be treated with the Morrow procedure.Case presentationHerein, we presented a case of a 64-year-old female diagnosed with a single left coronary artery with severe HOCM. The HOCM was treated with the Morrow procedure. The patient was discharged on the seventh postoperative day and was asymptomatic during the follow-up.ConclusionTo our knowledge, this is the first study reporting a single left coronary artery with severe HOCM treated with the Morrow procedure. In addition, myocardial protection by cardioplegia antegrade perfusion was safe for the patient with SCA and HOCM.
