Abstract
Objectives
Percutaneous ostium secundum atrial septal defect (ASD II) closure has become the standard of care for treatment of congenital ASD II in adults. Nevertheless, patients are frequently ineligible for this technique due to challenging morphology. In such cases, closure via minimally invasive cardiac surgery (MICS) is an appropriate treatment option. The aim of this study is to compare outcomes of MICS and use of a percutaneous Amplatzer septal occluder (ASO) device for treatment of ASD II in adults.
Methods
From July 2002 to June 2014, 95 patients underwent MICS for congenital ASD II closure. During the same period, 169 patients underwent ASO procedure. Outcomes in terms of remaining ASD II, new onset atrial fibrillation (AF), post-interventional stroke, myocardial infarction and the post procedural implementation of anticoagulation were compared.
Results
Apart from age (38.3 ± 12.7 vs 49.6 ± 15.7 years, P < 0.0001) the groups did not differ in baseline characteristics. A significantly higher rate of residual ASD II was found in the ASO group at 3 months (0% vs 30.8%, P < 0.0001), 6 months (0% vs 15.9%, P < 0.0001) and 12 months follow-up (0% vs 7.1%, P = 0.005). A significantly higher rate of new-onset AF was seen in the ASO group (0% vs 9.5%, P = 0.0008).
Conclusions
MICS for ASD II is a safe and reproducible procedure with 0% mortality in our cohort. More complete closure of ASD, decreased rates of new onset AF and decreased need for oral anticoagulation are the advantages of the MICS procedure. Compared with the current standard of care, the MICS approach is feasible regardless of ASD morphology.
