Percutaneous closure of atrial septal defects without balloon sizing in adults: Experience of a tertiary referral center

Abstract

Objective: We aimed to evaluate our clinical experience and short-term results of percutaneous closure of secunsdum type atrial septal defects (ASD) in adults. Methods: We studied 71 patients (49 female, 22 male, mean age 35p14 years) undergoing percutaneous clossure of ASD between January 2010-October 2012 in our clinic. All procedures were performed under sedoanalgessia without balloon sizing. Clinical characteristics of pastients, properties of percutaneous closure intervention, complications and short-term results are evaluated. Results: Defect diameter measured by transesophageal echocardiographic examination was 19.8p6.4 mm. Desvice size used for percutaneous closure was 24.7p6.7 mm. Procedure was successfully performed in 67 patients (94%). Four patients were referred for surgery because of procedural failure. During procedure, a patient developed transient 2nd degree AV block, and another developed device thrombosis. Residual shunt was detected in three patients at first day control echocardiographic examinastion. In the follow-up of 13p8 months, no residual shunt, embolic or arrhythmic complications were observed. Conclusion: Percutaneous closure of secundum ASD is a safe and effective method with high success and low complication rates in experienced centers. J Clin Exp Insvest 2013; 4 (1): 67-72
