Transcatheter Interatrial Shunt Device for the Treatment of Heart Failure
Prevalence of Heart Failure With Preserved Left Ventricular Ejection Fraction More than one-half of people with heart failure (HF) have a preserved left ventricular ejection fraction (HFpEF). Patients with HFpEF, commonly referred to as diastolic HF, have symptoms and/or signs of HF and a left ventricular ejection fraction (LVEF) >40% to 50%. The prevalence of HFpEF exceeds 3 million in the Uni...
متن کاملEmerging Drug Therapies for Heart Failure
Heart failure is associated with high morbidity and mortality and is proving to be an economic burden in developing countries. A number of therapeutic agents are presently employed in heart failure; but they are not sufficient to control symptoms of heart failure. Moreover, the prevalence of chronic heart failure is progressively increasing and thus there is a continuing need to develop effecti...
متن کاملInteratrial shunt devices for heart failure with normal ejection fraction: a technology update
Heart failure with normal ejection fraction (HeFNEF) accounts for ~50% of heart failure admissions. Its pathophysiology and diagnostic criteria are yet to be defined clearly which may hinder the search for effective treatments. The clinical hallmark of HeFNEF is exertional breathlessness, often due to an abnormal increase in left atrial pressure during exercise. Creation of an interatrial commu...
متن کاملInteratrial shunt for chronic pulmonary hypertension: differential impact of low-flow vs. high-flow shunting.
The purpose of the present study was to determine for the first time the qualitative and quantitative impact of varying degrees of interatrial shunting on right heart dynamics and systemic perfusion in subjects with chronic pulmonary hypertension (CPH). Eight dogs underwent 3 mo of progressive pulmonary artery banding, following which right atrial and ventricular end-systolic and end-diastolic ...
