Abstract:
Objective To study the prognostic value of left ventricular endocardial pacing in percutaneous transluminal septal myocardial ablation(PTSMA)in patients with hypertrophic obstructive cardiomyopathy(HOCM).Methods Fifteen HOCM patients with resting left ventricular outflow gradient(LVOTG)≥30 mmHg and/or stress LVOTG≥50 mmHg were included in this study.Left ventricular endocardial pacing was attempted in the patients 20 minutes before PTSMA.Heamodynamic parameters and LVOTG were monitored during operation and follow up echocardiography was performed 1 month after the operation.Results The mean chickness of the ventricular septals decreased from 22.07?7.85 mm before PTSMA to 17.39?5.79 mm 1 month afterwards(P
