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.
A heart valve is a biological one-way valve that allows blood to flow in one direction through the chambers of the heart. A mammalian heart usually has four valves. Together, the valves determine the direction of blood flow through the heart. Heart valves are opened or closed by a difference in blood pressure on each side. [1] [2] [3]
The American Heart Association reported a major spike in interest in hands-only CPR in the days following Hamlin’s cardiac arrest, which could lead to greater bystander intervention and higher ...
Dr. Jayne Morgan, MD, cardiologist and vice president of medical affairs at Hello Heart, also says that not smoking is the best way to protect your heart. “More and more evidence is pointing to ...
Researchers from the University of British Columbia have developed a "groundbreaking coating" that could make blood-contacting devices safer. Dr. Jayachandran Kizhakkedathu discusses the benefits.
Valve repair is where the valve that is causing heart failure is modified by removing excess valve tissues that cause them to close too tightly. In some cases, annuloplasty is required to replace the ring around the valves. If the repair of the valve is not possible, it is replaced by an artificial heart valve. The final step is heart replacement.
Building on the work of Dr. Shinya Yamanaka of Japan, who discovered that specialized cells could be reprogrammed back to immature stem cells, Watt and his collaborators have taken this work ...
