Early return of reflected waves increases right ventricular wall stress in chronic thromboembolic pulmonary hypertension.

CONCLUSIONS: Poor RV function in patients with proximal CTEPH is related to an early return of reflected pressure wave. PVR, compliance and characteristic impedance do not explain differences in RV function between proximal and distal CTEPH.
