Correção de Defeitos Cardíacos Congênitos Simples em Crianças e Adolescentes por Meio de Minitoracotomias Correction of Simple Congenital Heart Defects in Children and Adolescents Through Minithoracotomies

2007 
Summary Objective: To evaluate the repair of congenital heart defects through minithoracotomies. Methods: Between January 1998 and March 2005, 98 patients underwent minithoracotomies for simple congenital heart defect repairs at our institution. All patients were female between the ages of 14 months and 16 years (mean 4.6) with weights ranging from 8 to 58 Kg (mean 20). Diagnoses included 78 cases of atrial septal defects (ASD) (six with associated partial anomalous pulmonary venous drainage and four with pulmonary valve stenosis) and 20 cases of perimembranous ventricular septal defects (PVSD). All diagnoses were confirmed with an echocardiogram; therefore, cardiac catheterization was not required. A right submammary minithoracotomy was performed on 10 pat ients and a minithoracotomy with a partial median sternotomy was performed on 88 patients. Results: All defects were corrected successfully with satisfactory exposure. Cardiopulmonary bypass times ranged from 8 to 30 min (mean 10) and aortic clamping times ranged from 5 to 22 min (mean 12). All patients were extubated in the operating room and hospital sta ys ranged from 3 to 7 days (mean 5). There were no deaths during the operation or severe postoperative complications. No residual shunts were observed.
