Abstract
Background: The right heart thrombus (RHT) embolizes from deep venous thrombi and sits in the right atrium or the right ventricle. We aimed to determine the occurrence and prognosis of the RHT in patients with pulmonary embolism.
Methods: We reviewed the cohort data of 622 patients with acute pulmonary embolism obtained from the registry of Tehran Heart Center. Demographic, physiological, clinical, and echocardiographic data, as well as clinical outcomes, were compared between patients with and without the RHT.
Results: The study population comprised 622 patients, including 329 men (52.8%). The mean age of the patients was 60.2±17.0 years. Thirty patients (4.8%) had echocardiographically proven RHT. Baseline demographic and clinical characteristics were not different between the 2 groups. Right ventricular dysfunction was more prevalent in the RHT (+) group, and more patients in this group were treated with thrombolysis (P=0.013 and P<0.001, respectively). Overall, 3 out of 21 patients (14.2%) in the RHT (+) group vs 29 out of 306 patients (9.4%) in the RHT (−) group died at 1 month (P=0.445) and 5 out of 21 patients (23.8%) in the RHT (+) group vs 56 out of 307 patients (18.2%) in the RHT (−) group died at 1 year (P=0.562).
Conclusion: The RHT is an influential complication in patients with pulmonary emboli, and it seems to increase the mortality rate of patients with acute pulmonary embolism.
