Echocardiographic Evaluation in Cardiac Resynchronization Therapy: A Single Center Experience.

Introduction Heart failure develops as a result of dysfunction in the cardiac muscle, which impairs the heart's ability to pump blood effectively. For this reason, many studies have shown that cardiac resynchronization therapy (CRT) has significantly reduced symptoms and improved cardiac function in patients with heart failure. Echocardiography is crucial in assessing CRT response, as it helps differentiate between patients who benefit from CRT and those who do not by evaluating key parameters like left ventricular ejection fraction (LVEF), a critical parameter in determining CRT eligibility.
