Stories That Inspire Global Impact

An LV pseudoaneurysm is a contained rupture of the left ventricular wall, typically a serious complication following myocardial infarction, cardiac surgery, or trauma. Unlike a true aneurysm, it lacks endocardial and myocardial layers, instead being walled off by thrombus and pericardium. This critical distinction is vital in cardiac ultrasound for accurate diagnosis, as rupture risk…

A true left ventricular (LV) aneurysm is a localized, scarred, and thinned segment of the left ventricular wall that bulges outward during both systole and diastole. Unlike a pseudoaneurysm, a true aneurysm contains all layers of the cardiac wall. It is typically a late complication of a transmural myocardial infarction, where necrotic myocardial tissue is…

Myocarditis findings in cardiac ultrasound often include global or regional wall motion abnormalities, indicating impaired heart muscle function. You may also observe myocardial edema, appearing as increased wall thickness with a ground-glass texture, alongside pericardial effusion. These sonographic markers are crucial for diagnosing myocarditis, an inflammatory heart condition. Early identification through cardiac ultrasound helps guide…

End-stage heart failure, in cardiac ultrasound, reveals profound structural and functional abnormalities. Key findings often include severe ventricular dilation, markedly reduced ejection fraction, significant wall motion abnormalities, and valvular regurgitation. Ultrasound helps assess chamber size, wall thickness, and contractility, guiding management and prognosis. Sonographic indicators of end-stage heart failure also encompass increased filling pressures, evidence…

The Shock Evaluation Protocol in cardiac ultrasound is a rapid, systematic assessment to identify and characterize the cause of circulatory shock. This protocol typically involves focused ultrasound views of the heart, IVC, lungs, and abdomen to quickly detect conditions like severe internal bleeding (hemoperitoneum or hemothorax), pericardial effusion leading to cardiac tamponade, severe left ventricular…

Myocardial strain imaging, a crucial technique in cardiac ultrasound, assesses heart muscle deformation (strain) during the cardiac cycle. This advanced echocardiographic method offers precise quantification of myocardial function, detecting subtle impairments often missed by traditional ejection fraction measurements. It's invaluable for early diagnosis of cardiomyopathies, ischemia, and cardiotoxicity, providing critical insights for patient management and…

Global longitudinal strain (GLS) is a sophisticated echocardiographic parameter in cardiac ultrasound, quantifying the myocardial deformation along the long axis of the left ventricle. It represents the percentage of shortening of the heart muscle fibers from base to apex during systole. GLS is a highly sensitive and reproducible measure for detecting subtle changes in ventricular…

Cardiac tamponade physiology describes the critical condition where excessive fluid buildup in the pericardial sac compresses the heart, severely impairing its ability to fill with blood and pump effectively. This increase in intrapericardial pressure restricts ventricular diastole, leading to reduced cardiac output, hypotension, and eventually cardiogenic shock if untreated. Understanding this hemodynamic compromise is vital…

RV systolic dysfunction in cardiac ultrasound refers to the impaired ability of the right ventricle to pump blood effectively, leading to reduced ejection fraction. This critical condition impacts pulmonary circulation and systemic venous return, often stemming from pulmonary hypertension, chronic lung disease, or left heart failure. Early detection via echocardiography is vital for appropriate medical…
