Noninvasive assessment of pulmonary vascular resistance: a synergistic approach using computed tomography pulmonary angiography and echocardiography in pulmonary hypertension.

ABSTRACT:

Background

Pulmonary vascular resistance (PVR) is essential in managing pulmonary hypertension (PH) and has prompted the search for noninvasive assessment techniques. This study investigates the integration of morphological parameters from computed tomography pulmonary angiography (CTPA) and functional parameters from transthoracic echocardiography (TTE) to develop a noninvasive method for evaluating PVR in patients with PH.

Methods

Data from PH patients who underwent CTPA, TTE, and right heart catheterization (RHC) were analyzed retrospectively. The Cobb angle, defined as the angle between the spine and interventricular septum, was calculated by CTPA. It is assumed that thorax geometry, pericardial morphology, and body surface area (BSA) are factors influencing the Cobb ang
