An automated external defibrillator or automatic electronic defibrillator (AED) is a portable electronic device that automatically diagnoses the life-threatening cardiac arrhythmias of ventricular fibrillation (VF) and pulseless ventricular tachycardia, [1] and is able to treat them through defibrillation, the application of electricity which stops the arrhythmia, allowing the heart to re ...
An artificial heart valve is a one-way valve implanted into a person's heart to replace a heart valve that is not functioning properly (valvular heart disease). Artificial heart valves can be separated into three broad classes: mechanical heart valves, bioprosthetic tissue valves and engineered tissue valves.
The valve is sewn into a fabric-covered sewing ring, facilitating secure attachment within the patient's aortic annulus during the implantation procedure. The design aims to closely mimic the natural function of the human aortic valve, allowing for efficient blood flow and minimizing the risk of complications.
Aortic valve replacement is a cardiac surgery procedure whereby a failing aortic valve is replaced with an artificial heart valve. The aortic valve may need to be replaced because of aortic regurgitation (back flow), or if the valve is narrowed by stenosis .
Advisers to the U.S. Food and Drug Administration on Tuesday backed an approval for Abbott Laboratories' heart valve repair device that is designed for patients who are at risk of complications or ...
Mitral valve repair is mainly used to treat stenosis (narrowing) or regurgitation (leakage) of the mitral valve. [citation needed] A mitral balloon valvuloplasty enlarges the valve opening to allow greater oxygenated blood flow into the left ventricle, and since severe mitral regurgitation can be a major complication, degrees of stenosis, regurgitation, and valve anatomical features are taken ...
Tissue engineered heart valves (TEHV) offer a new and advancing proposed treatment of creating a living heart valve for people who are in need of either a full or partial heart valve replacement. Currently, there are over a quarter of a million prosthetic heart valves implanted annually, [ 1 ] and the number of patients requiring replacement ...
In Nebraska, PLWH newly covered by Medicaid expansion in 2013-14 were four times more likely to be virally suppressed than PLWH who were eligible but remained uninsured. [241] As an early adopter of Medicaid expansion, Massachusetts found a 65% rate of viral suppression among all PLWH and an 85% rate among those retained in healthcare in 2014 ...
