Table 1 Clinical characteristics of the 51 patients before and 1 day after transcatheter closure of an atrial septal defect (ASD) or patent foramen ovale (PFO). The three patients who only underwent diagnostic balloon sizing of the defect are included in the ASD group. Differences in age, BSA, degree of TnT elevation, the procedural duration, defect size and device size between the subjects who underwent transcatheter ASD and PFO closure were evaluated with the Mann–Whitney U-test. Chi-squared analysis was used to examine the distribution of the cardiovascular risk factors and sex across the groups
