- Abstract
<bold>Introduction: </bold>Pulmonary vein isolation (PVI) is widely practiced for treating atrial fibrillation. Transseptal access is necessary with one or even more transseptal sheaths to perform PVI.<bold>Methods: </bold>In this prospective study, 31 patients were examined with transesophageal echocardiography before, immediately after and in a 3-, 6- and 12-month follow-up period for evaluation of iatrogenic atrial septal defect (iASD). All patients underwent PVI with double transseptal puncture.<bold>Results: </bold>An iASD was detected in 27/31 patients (87%) with a maximum diameter of 1.0 mm. After 3 months, the iASDs were completely closed in 26/27 (96.3%) patients. In 1/27 (3.7%) patients, there was an iASD detectable even after 12 months. Clinically no patient suffered from cerebral or cardiac embolism in the follow-up period.<bold>Conclusions: </bold>We were only able to find small iASDs with left to right shunting after PVI but none with right to left shunting. iASDs following PVI show a high spontaneous closure rate already at 3 months of follow-up and are not associated with an increased rate of paradoxical embolism.
