Implication

Deformation parameters may better reflect regional RV recovery after PEA than TAPSE; leaves open their role in CTEPH monitoring pending prospective validation.

Does deformation imaging describe right ventricular function better than TAPSE in patients with CTEPH undergoing pulmonary endarterectomy?

Population

33 patients with chronic thromboembolic pulmonary hypertension (CTEPH), of which 16 were evaluated clinically and with echocardiography before and after pulmonary endarterectomy (PEA)

Intervention

Pulmonary endarterectomy (PEA)

Comparator

Pre-operative baseline

Outcome

Right ventricular function assessed by RV fractional area change (RVFAC), tricuspid annular plane systolic excursion (TAPSE), and peak ejection strain (S) and strain rate (SR) of the RV free wallsurrogate

Motion-independent deformation parameters (strain and strain rate) are superior to TAPSE for accurately describing regional right ventricular function after pulmonary endarterectomy in CTEPH patients.
