Participants
In all, 45 participants formed our studied sample. We enrolled 15 patients after successful ASD device closure (ASD-D group, mean age: 9 ± 3 years; 4 boys) and 15 age- and sex-matched patients after successful ASD surgical closure (ASD-S group, mean age: 9 ± 3 years; 4 boys). All patients underwent ASD correction at least 6 months before the study (ASD-D [atrial septal defect device closure] group: range 6-48 months, median 12 months; ASD-S [atrial septal defect surgical closure] group: range
Results
Clinical and standard echocardiographic characteristics of the studied sample are listed in Table 1.
The age at ASD repair and the ASD diameter were comparable between patient groups.
Right ventricular end-diastolic dimension for patients with ASD-S was significantly larger than in control subjects and patients with ASD-D.
Standard transmitral and transtricuspid flow Doppler evaluation was similar among groups.
Discussion
This is the first attempt to study atrial function for patients after successful ASD closure. Our results demonstrate that percutaneous ASD closure preserves both RA and LA deformation properties.
Despite the successful surgical closure of an ASD, the incidence of atrial arrhythmias in these patients is high.15 This has been attributed to electrophysiologic abnormalities related to the age at the time of surgical repair, and the pulmonary arterial pressure.1, 2, 15
