WebECG-synchronized CT scan and CTA in predicting outcome. Results: In 113 patients with PE, RV and LV ejection fraction (EF) and RV/LV diameter and vol-ume ratios were associated with adverse outcome ( P,.05), whereas vascular obstruction index was not. RVEF had the largest area under the receiver operating characteristic curve (0.75; 95% CI, WebOct 30, 2024 · We confirm this suspicion demonstrating over 90% have an RV-to-LV diameter ratio of ≥ 0.9 on CT, while such a finding was present on less than 2/3 of patients without syncope. These rates are similar to findings of RV strain in patients with acute PE by echocardiography by Jenab et al. [ 6 ].
