Stories That Inspire Global Impact

Pericardial thickening, when assessed in cardiac ultrasound, refers to an abnormal increase in the thickness of the pericardium, the sac surrounding the heart. This condition often results from chronic inflammation, infection, or radiation therapy, leading to a rigid, less pliable pericardial sac. Early detection via echocardiography is crucial for managing symptoms like shortness of breath…

An LV thrombus, or left ventricular thrombus, is a blood clot that forms inside the left ventricle of the heart, often a complication of myocardial infarction (heart attack) or dilated cardiomyopathy. This "cardiac ultrasound" finding is crucial as these clots can dislodge and travel to other parts of the body, leading to serious complications like…

Cardiac tamponade physiology describes a life-threatening condition where fluid accumulates in the pericardial sac, severely compressing the heart. This impedes the heart's ability to fill with blood during diastole, leading to reduced cardiac output, hypotension, and potential circulatory collapse. Early diagnosis via medical ultrasound is crucial. Ultrasound plays a vital role in identifying tamponade physiology,…

Mitral regurgitation (MR) in cardiac ultrasound refers to the abnormal backflow of blood from the left ventricle into the left atrium during systole due to incompetent mitral valve closure. This condition can lead to volume overload in the left atrium and ventricle, potentially causing heart failure. Early detection of MR is crucial for cardiac health,…

Aortic stenosis (AS) in cardiac ultrasound refers to the narrowing of the aortic valve, restricting blood flow from the left ventricle to the aorta. This critical condition increases the heart's workload, leading to symptoms like chest pain, shortness of breath, and syncope. Early detection through medical ultrasound is crucial for diagnosis and timely intervention to…

Left Ventricular (LV) hypertrophy, in cardiac ultrasound, refers to the abnormal thickening of the heart's main pumping chamber wall. This condition often results from increased workload, such as uncontrolled hypertension or aortic stenosis, making the heart muscle less efficient at pumping blood. Early detection via echocardiography is crucial for managing heart health and preventing progression…

Ejection Fraction (EF) is a vital measurement in cardiac ultrasound, quantifying the percentage of blood pumped out of the left ventricle with each heartbeat. This crucial indicator assesses global left ventricular systolic function, providing essential insights into the heart's pumping efficiency. A healthy EF typically ranges from 55-70%, while lower values may indicate heart failure…

Tricuspid Annular Plane Systolic Excursion (TAPSE) is a crucial echocardiographic parameter used in cardiac ultrasound to assess right ventricular (RV) systolic function. It measures the longitudinal motion of the tricuspid annulus towards the apex during systole. A healthy RV function is indicated by higher TAPSE values, while reduced values often suggest RV dysfunction, which can…

RVSP, or Right Ventricular Systolic Pressure, is a critical echocardiographic measurement in cardiac ultrasound, estimating the pressure within the right ventricle during systole. It's often calculated using the tricuspid regurgitation (TR) jet velocity and an estimation of right atrial pressure, providing invaluable insights into pulmonary artery pressure and the presence of pulmonary hypertension. Accurate assessment…
