  • Title: Percutaneous septal ablation for hypertrophic cardiomyopathy and mid-ventricular obstruction.
    Author: Seggewiss H, Faber L.
    Journal: Eur J Echocardiogr; 2000 Dec; 1(4):277-80. PubMed ID: 11916606.
    Abstract:
    AIMS: Percutaneous transluminal septal myocardial ablation by alcohol-induced septal branch occlusion is a new treatment option in symptomatic patients with hypertrophic cardiomyopathy and subaortic, SAM-associated obstruction. We report on a patient with mid-ventricular obstruction and echocardiographic-guided reduction of septal hypertrophy. METHODS AND RESULTS: A 52-year-old woman with NYHA class III and recurrent exercise-induced syncope suffered from hypertrophic cardiomyopathy with mid-ventricular obstruction. She had a systolic gradient of 71 mmHg at rest and 153 mmHg post-extrasystole, and diastolic inflow gradient of 20 mmHg. Echo-guided percutaneous transluminal septal myocardial ablation with occlusion of the fourth septal branch resulted in acute reduction and final elimination of systolic, as well as diastolic resting and provocable gradients. Complications were not seen. At 3 months' follow-up the patient was asymptomatic and without further syncopes. CONCLUSIONS: Echocardiographic-guided percutaneous transluminal septal myocardial ablation is able to reduce gradients in hypertrophic cardiomyopathy and mid-ventricular obstruction with consecutive improvement of symptoms.
