Objective: We aimed to evaluate our clinical experience and short-term results of percutaneous closure of secundum type atrial septal defects (ASD) in adults.
Methods: We studied 71 patients (49 female, 22 male, mean age 35±14 years) undergoing percutaneous closure of ASD between January 2010-October 2012 in our clinic. All procedures were performed under sedoanalgesia without balloon sizing. Clinical characteristics of patients, properties of percutaneous closure intervention, complications and short-term results are evaluated.
Results: Defect diameter measured by transesophageal echocardiographic examination was 19.8±6.4 mm. Device size used for percutaneous closure was 24.7±6.7 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 examination. In the follow-up of 13±8 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.
