Echocardiography- commonly referred to as "echo," is a non-invasive imaging technique that uses ultrasound waves to produce detailed images of the heart’s structure and function. It plays a crucial role in the diagnosis, management, and follow-up of patients with various cardiovascular conditions. Through real-time visualization, echocardiography helps assess heart chamber size, wall motion, valve function, and blood flow dynamics, making it an indispensable tool in modern cardiology.
