  2. Automated external defibrillator - Wikipedia

    en.wikipedia.org/wiki/Automated_external...

    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 ...

  3. Aortic valve replacement - Wikipedia

    en.wikipedia.org/wiki/Aortic_valve_replacement

    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 .

  4. Artificial heart valve - Wikipedia

    en.wikipedia.org/wiki/Artificial_heart_valve

    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.

  5. Defibrillation - Wikipedia

    en.wikipedia.org/wiki/Defibrillation

    Defibrillation is a treatment for life-threatening cardiac arrhythmias, specifically ventricular fibrillation (V-Fib) and non-perfusing ventricular tachycardia (V-Tach). [1] [2] A defibrillator delivers a dose of electric current (often called a counter-shock) to the heart.

  6. Hancock Aortic Tissue Valve - Wikipedia

    en.wikipedia.org/wiki/Hancock_Aortic_Tissue_Valve

    The Hancock Aortic Tissue Valve was invented by Warren Hancock. [4] In the late 1960s and early 1970s, Warren Hancock, an American engineer, collaborated with the medical community to develop a cutting-edge bioprosthetic heart valve. The valve was first introduced by the American company Medtronic. [1]

  7. Heart valve repair - Wikipedia

    en.wikipedia.org/wiki/Heart_valve_repair

    Heart valve repair is a cardiac surgery procedure, carried out to repair one or more faulty heart valves. In some valvular heart diseases repair where possible is preferable to valve replacement . A mechanical heart valve is a replacement valve that is not itself subject to repair.

  8. Aortic valve repair - Wikipedia

    en.wikipedia.org/wiki/Aortic_valve_repair

    Aortic valve repair or aortic valve reconstruction is the reconstruction of both form and function of a dysfunctional aortic valve. Most frequently it is used for the treatment of aortic regurgitation. [1] It can also become necessary for the treatment of aortic aneurysm, less frequently for congenital aortic stenosis.

  9. Björk–Shiley valve - Wikipedia

    en.wikipedia.org/wiki/Björk–Shiley_valve

    Björk–Shiley valve, as depicted in patent #US003824629. The Björk–Shiley valve is a mechanical artificial heart valve. The valve was co-invented by American engineer Donald Shiley and Swedish heart surgeon Viking Björk. Beginning in 1971, it has been used to replace aortic valves and mitral valves. It was the first successful tilting ...
