Excerpt
Right ventricular (RV) dysfunction is an important marker to predict morbidity and mortality in patients with acute pulmonary embolism (PE) [
1,
2]. Because it provides a cine assessment, echocardiography is the first-line method to evaluate RV dysfunction. However, since CT pulmonary angiography (CTPA) is the standard diagnostic modality for PE [
3], echocardiography is generally performed after the clinical suspicion of PE has been confirmed by CTPA. Thus there has been considerable interest in detecting RV dysfunction on CTPA. Many CT signs of RV dysfunction have been proposed [
4], but the most commonly used is RV enlargement as measured by the right to left ventricular (RV/LV) diameter ratio. …
