Transcatheter Versus Surgical Closure of Atrial Septum Defect: A Debate from a Developing Country

This study compares the effectiveness and cost of trans-catheter verses surgicalclosure of secundum atrial septum defect (ASD). ASD accounts for 10% of congenital cardiacdefects. Trans-catheter closure of secundum ASD is increasingly used as the primary intervention.Surgical repair is advised in a proportion of secundum type defects which are unsuitable fordevice closure. We reviewed the clinical course of 176 patients who underwent closure of isolatedsecundum ASD. The patients were assigned to either the device or surgical group depending uponthe treatment they received. Successful closure was assessed immediately after the procedure. Thefollowing outcomes were studied: mortality, morbidity, hospital stay, and costs. Ninety five patients were in the surgical group and 81 patients were in the groupundergoing device closure. The median age was 14.0 years (range 1.1-61.0) for surgical groupand 24.0 years (range 0.5-68.0) for the device group. The mortality in both groups was 0. Theprocedure success rate was 100% for the surgical group and 96.3% for the device group. Thecomplication rate was 13.7% for surgical group and 7.4% for the device group. The mean lengthof hospital stay was 5.0 ± 2.7 days for surgical group and 3.0 ± 0.4 days for device group. Theprocedure cost for surgery was found to be 12.3% lower than that of trans-catheter closure. Successful closure is achieved by both methods. Trans-catheter closure results inlower rate of complication and hospital stay but the cost of the procedure tends to be higherthan surgery.
