TRICUSPID REGURGITATION
In the spontaneous iASD closure group, the RV basal diameter declined in comparison to the baseline echocardiography (38 [IQR 33-40] vs 33 [IQR 30-35] mm, p = 0.043) and a numerical rise in TAPSE could be observed (12 [IQR 8.5-17.5] vs 16 [IQR 11.75-18.75] mm, p = 0.058). Besides this, no significant changes regarding other chamber diameters, LV function or pulmonary artery pressures (PAPs) were observed. Chamber diameters, LV function and PAPs remained unchanged in comparison to baseline evaluation.Reduction of the MR and tricuspid regurgitation maintained at 6-month follow-up without any significant differences compared to 1-month post-M-TEER (Table
