Echocardiography

Part of the Respiratory Medicine book series (RM, volume 12)

Abstract

In this chapter we aim to explore the role of the echocardiographic-Doppler examination in the evaluation and management of patients with pulmonary hypertension (PH). Too often, the echo-Doppler examination is primarily viewed as a method of “screening” for the presence of PH by Doppler estimation of increased pulmonary arterial pressure (PAP). While Doppler pressure estimation is important, an overemphasis on PAP estimation often occurs without recognition of the inherent imprecision of these methods and importantly, often neglects critically important two-dimensional (2D) and additional Doppler parameters that provide pivotal diagnostic, prognostic, and therapy-guiding information. It is the integration of relevant 2D and Doppler parameters that provide a comprehensive view of the underlying pathophysiology of PH. For example, several signature findings, well studied and validated, will help in differentiating the two major causes of PH, namely, PH that is caused by pulmonary venous hypertension (PHPVH) from PH that is caused by pulmonary vascular disease (PHPVD).
