12 kwi 2018 · The diverse causes of right-sided heart failure (RHF) include, among others, primary cardiomyopathies with right ventricular (RV) involvement, RV ischemia and infarction, volume loading caused by cardiac lesions associated with congenital heart disease and valvular pathologies, and pressure loading resulting from pulmonic stenosis or pulmonary ...
22 mar 2023 · Pathophysiology of Right Ventricular Failure. The main determinants of right ventricular function, like those of left ventricular function, are preload, afterload, contractility, and lusitropy.
3 lis 2022 · Right heart failure (RHF) is a clinical syndrome in which symptoms and signs are caused by dysfunction of the right heart structures (predominantly the right ventricle [RV], but also the tricuspid valve apparatus and right atrium) or impaired vena cava flow, resulting in impaired ability of the right heart to perfuse the lungs at normal central ...
17 lip 2023 · Heart failure is a condition in which the heart loses its ability to pump blood efficiently to the rest of the body. Right heart failure is most commonly a result of left ventricular failure via volume and pressure overload. Clinically, patients will present with signs and symptoms of chest discomfort, breathlessness, palpitations, and body ...
4 lis 2019 · Clinical Signs. The clinical signs of RV failure are mainly determined by backward failure causing systemic congestion. In severe forms, the right heart dilates and, through interventricular dependence, can compromise LV filling, reducing LV performance and causing forward failure (i.e. hypotension and hypoperfusion).
12 gru 2016 · This article reviews the pathophysiology, epidemiology and clinical presentation of right ventricular failure (RVF), a common complication of left ventricular failure (LVF) and pulmonary hypertension. It also discusses the role of imaging modalities in the diagnosis and the treatment options for RVF.
2 paź 2022 · Right-sided heart failure occurs when the right ventricle cannot pump blood effectively, leading to blood backup and swelling. It can be caused by pulmonary hypertension, valvular heart disease, heart attack, or other conditions.
