An electrocardiographic examination (ECG) showed a normal sinus rhythm of 86 beats/min, generalized QRS widening, and left ventricular hypertrophy (Fig. 1).

In the same session, the patient received sternotomy and septal myectomy (1 cm thickness and 8 cm length) under cardiopulmonary bypass, thinning of the anterior papillary muscle, which was identified to have become thicker and adhered to the septum at the apical part, and epicardial ICD implantation because he was in the high-risk group for sudden cardiac death (Fig. 3).
