Analysis of Regional Right Ventricular Function by Tissue Doppler Imaging in Patients with Aortic Stenosis.

ABSTRACT:

Background

Right ventricular (RV) dysfunction is frequently observed in patients with aortic stenosis (AS). Nevertheless, assessment of regional RV deformation is yet not performed. The aim of the study was to analyze the impact of moderate and severe AS on global and regional RV function by a multisegmental approach using tissue Doppler imaging (TDI).

Methods

In 50 patients (Group I - AS [n = 25] and Group II - normal controls [n = 25]), additional echocardiographic views of the RV were prospectively performed. The TDI sample volume was placed in the basal myocardial region of the anterior (RV-anterior), inferior (RV-inferior), and free RV wall (RV-free wall) to assess the following parameters: S'_RV, E'_RV, and A'_RV waves; IVCT<
