摘要
Background Pulmonary endarterectomy (PEA) is the treatment of choice for chronic thromboembolic pulmonary hypertension (CTEPH), while balloon pulmonary angioplasty (BPA) is an alternative for inoperable patients. We aimed to compare right ventricular (RV) remodelling and late survival after PEA and BPA. Methods In this prospective observational cohort study, we performed echocardiography at baseline and follow-up in patients with CTEPH treated with PEA (n=54) or BPA (n=44) between 2011 and 2022. Results Follow-up echocardiography was performed at 5 months (IQR 4–7) after PEA and 3 months (IQR 2–4) after the last BPA. Both groups showed significant improvements in left ventricular end-systolic eccentricity index, RV basal diameter and RV fractional area change (RV FAC). Tricuspid regurgitation pressure decreased by 26±18 mm Hg after PEA and 13±21 mm Hg after BPA (p=0.02 for between-group difference). Tricuspid annular systolic excursion (TAPSE) decreased by 4±5 mm after PEA but increased by 1±4 mm after BPA (p<0.001). The TAPSE/systolic pulmonary artery pressure ratio improved similarly in both groups. Five-year survival was 96% (95% CI 86% to 99%) for PEA and 79% (95% CI 61% to 89%) for BPA (p=0.25). Change in RV FAC was an independent predictor of survival (HR 0.9, 95% CI 0.82 to 0.99, p=0.03). Conclusions Both PEA and BPA led to significant RV reverse remodelling, with no clear evidence of a difference in survival rates. Improvement in RV function, particularly RV FAC, was associated with better outcomes, highlighting the importance of RV recovery in CTEPH treatment.
