Echocardiographic Evaluation in Cardiac Resynchronization Therapy: A Single Center Experience

Area of Science:

• Cardiology
• Medical Imaging

Background:

• Heart failure results from cardiac muscle dysfunction, impairing blood pumping.
• Cardiac resynchronization therapy (CRT) is a proven treatment for heart failure.
• Echocardiography is vital for assessing CRT effectiveness and patient response.

Purpose of the Study:

• To evaluate the role of echocardiography in assessing CRT efficacy in heart failure patients.
• To determine if echocardiographic parameters predict response to CRT.
• To analyze changes in left ventricular ejection fraction (LVEF) and volumes post-CRT.

Main Methods:

• Retrospective analytical cohort study of 53 heart failure patients who underwent CRT.
• Echocardiograms analyzed at baseline and at least six months post-CRT.
• Statistical analysis (paired t-tests) used to compare pre- and post-CRT echocardiographic parameters (EF, ESV, EDV).

Main Results:

• Mean ejection fraction (EF) significantly increased from 29.09% to 33.3% (p=0.0014).
• Mean end-systolic volume (ESV) decreased from 114.46 mL to 97.13 mL (p=0.056).
• Mean end-diastolic volume (EDV) decreased from 157.08 mL to 138.87 mL (p=0.0158).

Conclusions:

• Echocardiography demonstrates significant improvements in EF and ESV after CRT in heart failure patients.
• CRT is an effective therapy for heart failure with reduced ejection fraction.
• Echocardiography aids in identifying responders to CRT, guiding treatment decisions.
