RESUMO
Objiective To evaluate the effect of pearventricular device closure of non-muscular ventricular defercts(VSDs) in infants.Methods From April 2007 to February 2008,39 patients with non-muscular VSDs were received off pump surgical treatment,perventricular device closure were for all the patients.There were 16 males and 23 females with mean age of(14.5±7.8) months(12 to 36 months and mean weight of(12.4±2.3)kg(8.5 to 18.0 kg).There were 34 perimembranous and 5 subateria VSD.The diameter of defects were 3.0 to 11 mm[mean(6.1±2.0)mm].Results Thirty-seven(94.9%)VSDs ere successfully closed,while two were repaired under cardiopulmonary bypass(CPB)instead of device closure because of the complication of moderat aortic reurgitation.The diameter of occluders were 4 to 12mm[mean(8.2±2.0)mm].The tricuspid regurgitations decareasded after operation in 3 patients with perimenmbranous VSDs,while the closure caused new mild or trace tricuspid regurgitations in 8 patients.Six patients with perimembranours VSDs acquired the incomplete right bundle branch blocks affter device closure.The length of hospital stay was 3 to 5 days[mean(3.4±0.4)]after operation and no petient had blood transfusion.Conclustion Perventricular device closure is probably an effective and safe treatment for non-muscular VSDs in unfants.
