Abstract:
Objective To investigate the effectiveness and safety in pediatric patients (Age≤14 years) with hypertrophic obstructive cardiomyopathy (HOCM) treated by percutanous transluminal septal myocardial ablation (PTSMA). Methods Retrospectively analyzed the data from four pediatric(age≤14 years) patients with HOCM treated by PTSMA from March 2004 to June 2012, including their clinical data, coronary angiography and the results of PTSMA to evaluate the complication and clinical outcome after PTSMA. Results The left ventricular outlfow tract pressure gradient (LVOTPG) at rest decreased after operation when compared with pre-lablation level (32.0 mm Hg vs 80.0 mm Hg, P>0.05). The LVOTPG after premature beat decreased with signiifcant difference after ablation (40.0 mm Hg vs 122.5 mm Hg, P<0.05). During opration and hospitalization, 1 patient developed right bundle branch block, and another patient developed complete atrioventricular block, Both patients’ arrhythmia received after temporary pacing and medical treatment. No death and major clinical adverse event recorded after operation and during the 12 months follow up. Conclusions PTSMA was effective and safe for children with HOCM.
