[Implantation of a dual chamber pacemaker-defibrillator (DDD-ICD) in a patient with hypertrophic obstructive cardiomyopathy].
A 70-year-old woman with severely symptomatic hypertrophic obstructive cardiomyopathy was unresponsive to drug treatment. She had recurrent ventricular tachyarrhythmias and syncope and was at high risk for sudden death; a dual chamber pacemaker defibrillator (DDD-ICD) was implanted. Her initial left ventricular outflow tract gradient was 80 mm Hg and fell to 40 mm Hg during dual-chamber pacing at an atrial ventricular delay of 140 ms. In the follow-up over six months she was asymptomatic with respect to angina pectoris; ventricular tachycardias could be successfully terminated by antitachycardia pacing or by shocks. A dual chamber pacemaker defibrillator is an important therapeutic option for patients with symptomatic hypertrophic obstructive cardiomyopathy and ventricular tachyarrhythmias.
