Objective: We aimed to explore the feasibility of an inverted-T upper hemisternotomy approach for pulmonary endarterectomy (PEA) and report the results after 17 cases.
Methods: PEA was conducted through a 7-cm skin incision using an inverted-T upper hemisternotomy across the third intercostal spaces. Cardiopulmonary bypass (CPB) was established through central arterial and percutaneous femoral dual-staged venous cannulation.
Background: We conducted a volume-outcome (V-O) meta-analysis of PEA procedures for chronic thromboembolic pulmonary hypertension (CTEPH), to objectively determine the minimum required annual case load that can define a high-volume centre.
Methods: Three electronic databases were systematically queried until May 1st, 2024. Centres were divided in volume tertiles (Ts).
Mutations in the () gene and signaling pathway impairment are observed in heritable and idiopathic pulmonary arterial hypertension (PAH). In PAH, endothelial dysfunction is currently handled by drugs targeting the endothelin-1 (ET-1), nitric oxide (NO), and prostacyclin (PGI) pathways. The role of angiogenesis in the disease process and the effect of PAH therapies on dysregulated angiogenesis remain inconclusive.
