Successful treatment with biventricular pacing in a patient with hypertrophic obstructive cardiomyopathy

We report the effects of biventricular pacing in a patient with hypertrophic obstructive cardiomyopathy （HOCM） refractory to medical therapy. A 58-year-old man with HOCM had suffered from dyspnea, chest pain and palpitation for 5 years. Cardiac catheterization showed a left ventricular outflow tract...

Description
Summary:We report the effects of biventricular pacing in a patient with hypertrophic obstructive cardiomyopathy （HOCM） refractory to medical therapy. A 58-year-old man with HOCM had suffered from dyspnea, chest pain and palpitation for 5 years. Cardiac catheterization showed a left ventricular outflow tract （LVOT） gradient of 80 mmHg. He refused septal myomectomy and the septal ablation was not available. Based on intraoperative pressure measurements, he was implanted with biventricular pacing and LVOT gradient decreased to 10 mmHg. During the follow-up period of 6 months, the patient＇s symptoms were markedly improved. Biventricular pacing may be an alternative therapy for patients with HOCM.
