🫀 Diagnostic Soundwaves: Echocardiography Techniques and Their Central Utility in Cardiac Assessment
Echocardiography is a foundational, non-invasive diagnostic tool in cardiology that utilizes high-frequency sound waves (ultrasound) to create moving, real-time images of the heart's structure and function. The procedure provides crucial insights into how blood flows through the heart chambers and valves, offering clinicians a powerful method to diagnose and assess a wide range of cardiac conditions. Clinically, it is used to evaluate changes in heart size, assess the strength of the heart's pumping action (e.g., calculating ejection fraction), detect areas of heart muscle damage that may indicate a past heart attack, and check for various heart valve diseases like regurgitation or stenosis. Its non-ionizing nature makes it a safe, repeatable assessment for ongoing patient monitoring.
The technology encompasses several sophisticated techniques: Two-dimensional (2D) and Three-dimensional (3D) echocardiography provide detailed anatomical pictures of the heart walls and valves, with 3D offering superior visualization of complex structures. Doppler echocardiography measures the speed…
