Multimodality imaging in heart failure patients.

Area of Science:

• Cardiology
• Medical Imaging

Background:

• Heart failure diagnosis, staging, and treatment rely heavily on imaging modalities.
• Echocardiography is the preferred method due to accessibility, safety, and cost-effectiveness.

Purpose of the Study:

• To review the current role of various imaging techniques in heart failure management.
• To highlight emerging diagnostic methods and evolving applications of established techniques.

Main Methods:

• Review of current literature on echocardiography, cardiovascular magnetic resonance (CMR), and cardiac catheterization in heart failure.
• Analysis of diagnostic accuracy and prognostic value of different imaging modalities.

Main Results:

• Echocardiography, combined with biomarkers, is effective for heart failure diagnosis, with new methods for heart failure with preserved ejection fraction emerging.
• Cardiovascular magnetic resonance (CMR) is increasingly used for etiological assessment and evaluating myocardial deformation and fibrosis, potentially replacing some uses of cardiac catheterization.
• The role of cardiac catheterization for myocardial viability assessment is diminishing, and non-ECG based dyssynchrony assessment is being re-evaluated with growing cardiac resynchronization therapy use.

Conclusions:

• Echocardiography remains the cornerstone of heart failure imaging.
• Cardiovascular magnetic resonance (CMR) serves as a valuable complementary tool.
• The utility of invasive cardiac catheterization in heart failure management is decreasing.
