Ventricular septum curvature ratio: a novel imaging marker to predict clinical deterioration in normotensive acute pulmonary embolism.

ABSTRACT:

Background

Identifying high-probability deterioration individuals at the time of admission remains a challenge in normotensive patients with acute pulmonary embolism (PE). Ventricular septum (VS) deviation, as observed on computed tomography pulmonary angiography (CTPA), has been associated with poor prognosis in acute PE patients. However, the quantitative relationship between the VS curvature ratio and clinical deterioration in normotensive acute PE patients has not been fully explored. This study aimed to investigate the role of the VS curvature ratio derived from CTPA as an image marker for deterioration in normotensive acute PE patients.

Methods

This prospective multicenter cohort study enrolled normotensive patients with acute PE across five centers in China between Ja
