Surgical Myectomy After Failed Ablation For Hypertrophic Obstructive Cardiomyopathy

Background Hypertrophic cardiomyopathy is a genetic disease of the myocardial sarcolemma characterized by left ventricular hypertrophy. When obstruction to the left ventricular outflow tract is present and symptoms are refractory to medication, surgical myectomy or alcohol septal ablation is indicated.Case Description We report a case of a patient presented for myectomy due to recurrence only 1 year after alcohol ablation. Interesting findings were a firm subaortic membrane and a direct insertion of the papillary muscle into the mitral valve.Conclusion After myectomy and extensive papillary muscle mobilization, a significant relief of obstruction was achieved.
