Background: Portopulmonary hypertension (PoPH) is one of the major underlying causes of pulmonary arterial hypertension (PAH). However, PoPH, especially treatment strategies, has been poorly studied. Therefore, this study evaluated current treatments for PoPH, their efficacy, and clinical outcomes of patients with PoPH.Methods and Results: Clinical data were collected for patients with PoPH who were enrolled in the Japan Pulmonary Hypertension Registry between 2008 and 2021. Hemodynamic changes, functional class, and clinical outcomes were compared between patients with PoPH treated with monotherapy and those treated with combination therapies. Clinical data were analyzed for 62 patients with PoPH, including 25 treatment-naïve patients, from 21 centers in Japan. In more than half the patients, PAH-specific therapy improved the New York Heart Association functional class by at least one class. The 3- and 5-year survival rates of these patients were 88.5% (95% confidence interval [CI] 76.0–94.7) and 80.2% (95% CI 64.8–89.3), respectively. Forty-one (66.1%) patients received combination therapy. Compared with patients who had received monotherapy, the mean pulmonary arterial pressure, pulmonary vascular resistance, and cardiac index were significantly improved in patients who had undergone combination therapies.Conclusions: Combination therapy was commonly used in patients with PoPH with a favorable prognosis. Combination therapies resulted in significant hemodynamic improvement without an increased risk of side effects.

In patients with atrial septal defect (ASD), atrial left-to-right shunting causes left atrial (LA) remodeling and dysfunction, leading to atrial fibrillation (AF). In adults with ASD and concomitant AF, LA function should be evaluated after ASD closure plus AF radiofrequency catheter ablation (RFCA).This multicenter retrospective cohort study included patients who underwent transcatheter ASD closure at one of the four leading hospitals. Patients with a history of AF also underwent preceding RFCA. The association between AF history and LA ejection fraction (EF) (indicating LA global function) at 6-12 months following ASD closure was evaluated. To account for differences in baseline characteristics between patients with and without a history of AF, we conducted the following statistical methods: (1) multivariate regression analysis in the prepropensity score (PS)-matched cohort and (2) univariate comparisons in the PS-matched cohort.Overall, this study included 231 patients (30 with AF history, 201 without). Multiple regression analysis showed that AF history was independently associated with impaired LAEF (β = −10.425, P < 0.001, model created prior to propensity matching). A one-to-one PS matching (25 pairs) showed that the LAEF at 6-12 months following ASD closure was significantly impaired in patients with ASD and AF history compared to that in patients without history of AF (median LAEF, 37.5% (interquartile range [IQR] 29.4%-48.5%) versus 52.3 [IQR 50.0%-56.6%]; P < 0.001).LA function was impaired in patients with ASD and a history of AF at 6-12 months after successful transcatheter ASD closure and on maintenance of sinus rhythm by RFCA.
