Non-Invasive Assessment of Multivalvular Heart Disease: A Comprehensive Review

Area of Science:

• Cardiology
• Cardiovascular Imaging
• Valvular Heart Disease

Background:

• Multivalvular heart disease (MVD) involves lesions on two or more heart valves, increasingly common due to population aging.
• Each MVD combination alters patient hemodynamics, potentially affecting left ventricle (LV) dimensions, shape, and function over time.
• Standard echocardiographic parameters, developed for single valve disease, may be unreliable in MVD due to flow and load dependency.

Purpose of the Study:

• To review common MVD combinations and their echocardiographic interpretation challenges.
• To highlight the potential for errors in assessing MVD severity using standard echocardiographic methods.
• To explore multimodality assessment strategies for improved understanding and management of MVD.

Main Methods:

• Literature review focusing on echocardiographic assessment of MVD.
• Analysis of hemodynamic alterations caused by combined valvular lesions.
• Discussion of limitations of current echocardiographic parameters in MVD.
• Exploration of multimodality imaging approaches.

Main Results:

• Standard echocardiographic parameters can lead to misjudgment of MVD severity.
• Combined non-severe valve lesions can result in significant hemodynamic compromise and systolic dysfunction.
• Echocardiographic assessment in MVD necessitates careful consideration of combined valvular effects.

Conclusions:

• Accurate assessment of MVD requires awareness of echocardiographic caveats.
• Multimodality imaging offers enhanced understanding and management of MVD.
• Addressing MVD complexity is crucial for effective patient treatment and outcomes.
