The Right Ventricle in Cardiorespiratory Failure

Abstract

Purpose of Review

Thorough evaluation of the hypotensive or dyspneic patient requires an understanding of the physiology and common pathologies that relate to the right ventricle (RV). This review focuses on the role of point-of-care ultrasound (PoCUS) in evaluating the RV and discusses common clinical scenarios where PoCUS provides value.

Recent Findings

There are several signs of underlying RV pathology that can be detected using PoCUS; these including alterations in RV size, wall thickness, interventricular septal deviation, and RV function. These indicators help in differentiating between acute and chronic RV dysfunction. Recent findings include the role of more advanced and quantitative measures such as TAPSE, including their use in complex clinical situations such as acute cor pulmonale.

Summary

PoCUS can be used to supplement the history and physical examination in critically ill patients, specifically in the evaluation of RV dysfunction. This bedside tool is a valuable aid in guiding both diagnosis and management.
