Echocardiography in pulmonary arterial hypertension

Area of Science:

• Cardiology
• Pulmonology
• Medical Imaging

Background:

• Pulmonary arterial hypertension (PAH) significantly impacts right ventricular (RV) function.
• Echocardiography (ECHO) is a primary tool for evaluating RV status in PAH.
• Assessing RV geometry, interaction, and systolic function is vital for PAH management.

Purpose of the Study:

• To review the utility of various echocardiographic parameters for assessing RV function in PAH.
• To evaluate the prognostic significance of different ECHO measures.
• To explore future directions in echocardiographic imaging of the right heart in PAH.

Main Methods:

• Review of Doppler echocardiography techniques for RV function assessment.
• Analysis of direct and indirect ECHO measures of RV geometry and function.
• Evaluation of clinical relevance, reproducibility, and prognostic value of ECHO parameters.

Main Results:

• A combination of direct and indirect ECHO measures is essential for comprehensive RV assessment in PAH.
• Selected ECHO parameters offer prognostic value and are clinically relevant.
• The review synthesizes current understanding and identifies areas for future research.

Conclusions:

• Comprehensive echocardiographic assessment is critical for understanding PAH's impact on the RV.
• Clinically relevant and reproducible ECHO parameters aid in predicting patient status.
• Future ECHO imaging advancements promise enhanced characterization of right heart function in PAH.
