Key result
Pulmonary endarterectomy significantly reduced pulmonary arterial elastance and restored ventriculo-arterial coupling, leading to an improvement in right ventricular ejection fraction from 25% to 46%.

Pulmonary endarterectomy in CTEPH patients leads to immediate and significant reverse remodeling of the right ventricle, driven primarily by the normalization of afterload and restoration of ventriculo-arterial coupling.

Supports PEA for RV recovery in CTEPH; extends prior observations but leaves open durability and generalizability.
Rolf et al. (2014) conducted an observational in Chronic thromboembolic pulmonary hypertension (CTEPH) (n=65). Pulmonary endarterectomy (PEA) vs. Pre-operative baseline was evaluated on Pulmonary arterial elastance index (Ea-pulm_i) (p=0.0001). Pulmonary endarterectomy significantly reduced pulmonary arterial elastance and restored ventriculo-arterial coupling, leading to an improvement in right ventricular ejection fraction from 25% to 46%.
