Abstract
Patients who underwent transcatheter edge-to-edge repair (TEER) or transcatheter mitral valve replacement (TMVR) have a transeptal access created by an iatrogenic atrial septal defect (ASD) which leads to significant complications requiring closure. Given limited data, we used the National Inpatient Sample between 2015 and 2020 to evaluate the clinical outcomes of percutaneous closure of ASD (PC-ASD) in TEER/TMVR hospitalizations. A total of 44,065 eligible weighted hospitalizations with either TEER (n = 39,625, 89.9%) or TMVR (n = 4,440, 10.1%) with a higher rate of PC-ASD in the TMVR group (10.7% vs 2.0%, p < 0.01). The TEER with PC-ASD group were more likely to experience acute heart failure and right ventricular failure and had longer hospital stays but there was no difference in in-hospital mortality compared with the no PC-ASD group. In the TMVR group, there was no difference in the odds of acute heart failure, right ventricular failure, cardiogenic shock, or acute hypoxic respiratory failure, but the odds of mechanical circulatory support, in-hospital mortality, and length of stay were significantly higher in patients with PC-ASD in the TMVR group. In conclusion, rates of percutaneous closure of ASD after TEER were lower than after TMVR and associated with worse in-hospital mortality in TMVR but not in TEER. Further prospective clinical trials are needed to identify patients who would benefit from the closure of iatrogenic ASD.
