Stories That Inspire Global Impact

Tricuspid regurgitation (TR) is a cardiac condition characterized by the abnormal backflow of blood from the right ventricle into the right atrium during systole, due to improper closure of the tricuspid valve. This inefficiency in the heart's right side can lead to increased pressure in the right atrium and systemic veins, affecting overall cardiac function.…

The E/e’ ratio in cardiac ultrasound is a critical non-invasive measure used to assess left ventricular diastolic function and filling pressures. It's calculated by dividing the early diastolic mitral inflow velocity (E wave) by the early diastolic mitral annular velocity (e’ wave), reflecting the relationship between left atrial pressure and left ventricular relaxation. This ratio…

Tricuspid stenosis, in cardiac ultrasound, refers to the narrowing of the tricuspid valve opening, obstructing blood flow from the right atrium to the right ventricle. This rare valvular heart disease can lead to increased right atrial pressure and systemic venous congestion, often caused by rheumatic fever or congenital abnormalities. Early diagnosis via echocardiography is crucial…

Prosthetic valve assessment in cardiac ultrasound is crucial for monitoring the function and integrity of implanted heart valves. Regular echocardiographic evaluations detect complications like stenosis (narrowing), regurgitation (leakage), thrombus formation, endocarditis, or structural deterioration. This detailed imaging ensures optimal valve performance and patient well-being. Comprehensive medical ultrasound techniques, including Doppler and 2D/3D imaging, are employed…

Vegetation detection in cardiac ultrasound identifies abnormal growths on heart valves or endocardium, often indicative of endocarditis. These irregular masses, composed of platelets, fibrin, microorganisms, and inflammatory cells, can lead to serious complications like emboli or valvular damage. Early and accurate detection is crucial for timely diagnosis and management, significantly impacting patient outcomes. Utilizing advanced…

A Patent Foramen Ovale (PFO) in cardiac ultrasound refers to a small, flap-like opening between the heart's right and left atria that failed to close after birth. While often asymptomatic, a PFO can allow blood to shunt from the right to the left side of the heart, potentially leading to paradoxical embolism, stroke, or decompression…

ASD (Atrial Septal Defect) and VSD (Ventricular Septal Defect) detection in cardiac ultrasound involves identifying abnormal openings in the heart's septa. These congenital heart defects allow blood to shunt between the atria or ventricles, impacting blood flow and potentially leading to heart strain. Echocardiography is the primary non-invasive tool for diagnosing ASDs and VSDs, visualizing…

An intracardiac shunt, in cardiac ultrasound, refers to an abnormal connection between the heart's chambers or great vessels, allowing blood to bypass its normal circulatory path. This can lead to oxygenated and deoxygenated blood mixing, affecting cardiac efficiency and potentially causing conditions like pulmonary hypertension or cyanosis. Detecting and characterizing shunts is crucial for diagnosis…

A bubble study, or agitated saline contrast echocardiogram, is a crucial diagnostic technique in cardiac ultrasound. It involves injecting agitated saline solution intravenously to create microbubbles, which are then tracked as they pass through the heart chambers. This non-invasive method helps detect intracardiac shunts, such as patent foramen ovale (PFO) or atrial septal defects (ASD),…
