Early Postoperative Pulmonary Vascular Compliance Predicts Outcome After Pulmonary Endarterectomy for Chronic Thromboembolic Pulmonary Hypertension

BACKGROUND: Despite a major reduction in pulmonary vascular resistance (PVR), patients with chronic thromboembolic pulmonary hypertension (CTEPH) do not always return to functional New York Heart Association (NYHA) class I after pulmonary endarterectomy (PEA). We hypothesized that residual abnormal compliance (Cp) after PEA is associated with incomplete functional recovery despite major improvement in PVR. METHODS: The Cp of 34 consecutive …
