[Is echocardiography still helpful in cardiac resynchronization therapy?]

Area of Science:

• Cardiology
• Medical Imaging

Background:

• Cardiac resynchronization therapy (CRT) treats heart failure with left ventricular systolic dysfunction.
• Echocardiography is a non-invasive, repeatable imaging method used for patient evaluation.
• The role of echocardiography in CRT has varied over time.

Purpose of the Study:

• To review the current applications of echocardiography in cardiac resynchronization therapy.
• To define the utility of echocardiography before, during, and after CRT device implantation.

Main Methods:

• Literature review of clinical studies on echocardiography and CRT.
• Analysis of echocardiographic parameters for cardiac dyssynchrony, prognosis, and optimization.
• Synthesis of current evidence regarding echocardiography's role throughout the CRT process.

Main Results:

• Echocardiography provides essential anatomical and functional data for CRT patient selection and management.
• Specific echocardiographic parameters aid in assessing cardiac dyssynchrony and predicting response to CRT.
• The technique is valuable for optimizing pacing settings and monitoring treatment effectiveness post-implantation.

Conclusions:

• Echocardiography remains a cornerstone in the comprehensive management of patients receiving cardiac resynchronization therapy.
• Its non-invasive nature and detailed functional insights support its continued use in the entire CRT pathway.
• Further research may refine echocardiographic protocols for enhanced CRT outcomes.
