Abstract
Pulmonary hypertension (PH) is a serious complication that impairs the prognosis of congenital heart disease (CHD) patients. The Japanese Association of Congenital Heart Disease with Pulmonary Hypertension Registry (JACPHR) is a nationwide CHD-PH registry in Japan, established in 2021. We aimed to clarify the current status of pharmacological treatment for CHD-PH using JACPHR data. Data from 266 registered CHD-PH cases for JACPHR were analyzed. Patient characteristics revealed a median age of 11.6 years (range: 0.7-85 years), with 51.1% having systemic underlying diseases, the most common being Trisomy 21 (27.8%). Pharmacological treatments were used in 69% of cases, with combination therapy in 44%. The use of combination therapy was linked to concurrent PH and a high pulmonary vascular resistance index. Conversely, patients with left heart disease, especially those with total anomalous pulmonary venous return, were less likely to receive combination therapy. Tadalafil and macitentan were the most commonly used medications in all age groups, according to age-specific analysis. The drug dosages for pediatric patients were either consistent with the guidelines’ recommended doses or calculated using adult dosing recommendations. In conclusion, combination therapies for CHD-PH were widely used in Japan, including for pediatric patients, with treatment decisions based on the clinical context and disease severity. This study sheds light on the real-world application of PH-targeted therapies for CHD-PH.
