Why the study?
Can patients with primary pulmonary hypertension develop extensive central thrombi?
Can patients with primary pulmonary hypertension develop extensive central thrombi?
Large central thrombi can develop in primary pulmonary hypertension without being hemodynamically significant, highlighting the need for careful diagnostic evaluation to distinguish this from operable chronic thromboembolic pulmonary hypertension.
No takes yet. Share an insight, caveat, or question.
Central thrombi in primary pulmonary hypertension may evade perfusion scan detection without hemodynamic effects; leaves open anticoagulation role and CTEPH differentiation.
Moser et al. (1995) studied this question.
