Early complications following transcatheter occlusion of perimembranous ventricular septal defects in children / 中华心血管病杂志

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the early complications during and after transcatheter closure of perimembranous ventricular septal defects (PMVSDs) in children.</p><p><b>METHODS</b>A total of 223 patients received transcatheter closure of PMVSDs from March 2002 to December 2005 in our hospital were included in this retrospective study.</p><p><b>RESULTS</b>The overall complications rate was 26.9% (60/223). Major complications occurred in 9 patients (4.0%) including III degrees atrioventricular block (AVB) in 2 (0.9%), hemolysis in 3 (1.3%) and surgical interventions in 4 patients (1.8%) because of device malposition (1), mild aortic regurgitation (2) and device embolization (1) and all 4 patients recovered without further complications. The 2 patients with III degrees AVB were completely recovered to normal sinus rhythm after 7 days treatment with temporary pacemaker and corticosteroid. Hemolysis in 3 patients disappeared after corticosteroid treatment. Minor complications occurred in 51 patients (22.8%) including bundle branch block (BBB) in 37 (16.6%), first-degree AVB in 2 (0.9%), second-degree AVB in 1 (0.4%), new-onset mild aortic regurgitation in 5 (2.2%) and new-onset mild to moderate tricuspid regurgitation in 6 patients (2.6%). Except for right bundle branch blocks, other BBBs were treated with albumin and corticosteroid and completely recovered. No treatment was applied for new-onset valve regurgitations. There was no death in all 223 patients.</p><p><b>CONCLUSIONS</b>Early complications post PMVSDs in children are mostly minor with good prognosis and the prognosis for major complications post PMVSDs is good after proper treatment.</p>
