abstract = {Background: 2D-transesophageal echocardiography (TEE) is routinely performed to guide percutaneous ASD closure in children. We aimed to assess whether two-dimensional (2D)-transthoracic echocardiography (TTE) is a safe alternative for assessment and guidance of atrial septal defect (ASD) closure in unselected children.
Methods: We performed a retrospective single-center study including 389 consecutive children aged less than 15-year-old who underwent percutaneous ASD closure under 2D-TEE (1998–2005, n=133) or 2D-TTE (2005–2014, n=256). A balloon calibration was performed in all cases for the Amplatz Septal Occluder choice.
Results: ASDs were larger and rims deficiencies were more frequent in the TTE-guided group. The procedure was successful in 376 patients [96.7%; 95% confidence interval (CI), 94.4–98.2%]. The success rate tended to be higher in the TTE- versus TEE-guided group (98.0% versus 94.0%, P=0.069). Device migration occurred in 4 patients (1.0%; 95% CI: 0.3–1.6%), all after TEE-guided procedure (P=0.013). Early major adverse events were observed in 5 patients (1.3%; 95% CI: 0.4–3.0%), all in the TEE group (P=0.004). Fluroroscopic time and irradiation dose were not different among the 2 groups (P=0.450 and P=0.130 respectively). After a median follow-up of 7 years (range, 1–16 years), no adverse events was reported. One (0.3%, 95% CI: 0–1.4%) 12-year-old patient developed atrial fibrillation 5 years after the procedure. Pregnancies were uneventful in 72 cases.
Conclusions: When a balloon sizing is performed, 2D-TTE imaging is as efficient as 2D-TEE to guide percutaneous ASD closure in children. The procedure can safely be done in spontaneously breathing children under TTE guidance alone in experienced centers.},
