Abstract:Background
Assessment of the pattern of the RV outflow tract Doppler provides insights into the hemodynamics of chronic thromboembolic pulmonary hypertension (CTEPH). We studied whether pre-operative assessment of timing of the pulmonary flow systolic notch by Doppler echocardiography is associated with long-term survival after pulmonary endarterectomy (PEA) for CTEPH.
Methods
Fifty-nine out of 61 consecutive CETPH patients (mean age 53 ± 14 years, 34% mal… Show more
