Abstract:
Objective To evaluate the immediate and short term therapeutic efficacy of percutaneous transluminal septal myocardial ablation (PTSMA) in patients with hypertrophic obstructive cardiomyopathy (HOCM) and to investigate the prevention of the related complications. Methods PTSMA was conducted in 3 patients with HOCM refractory to medication. The immediate effect was evaluated by pressure monitor, but the follow up effect by observation of the clinical symptoms and ultrasonic cardiogram. Results The left ventricular outflow tract gradients triggered by ventricular premature beats decreased from 143 mmHg (ranging from 70 to 180 mmHg) to 53 mmHg (ranging from 30 to 80 mmHg). Complete atrioventricular block (Ⅲ?AVB) with atrioventricular node rhythm was found in 1 case, and complete right branch bundle block (CRBBB) in another one. Follow up of the 3 cases at 6 months after operation revealed remarkable improvement of the patients' cardiac function (NYHA), disappearance of angina pectoris, and obvious attenuation of ventricular septal hypertrophy and SAM (systolic anterior motion of mitral) phenomenon. Conclusion PTSMA is an effective method with satisfactory short term effect for the patients with HOCM refractory to medication.
