    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.

  3. Minimally invasive cardiac surgery - Wikipedia

    en.wikipedia.org/wiki/Minimally_invasive_cardiac...

    Minimally invasive cardiac surgery, encompasses various aspects of cardiac surgical procedures (aortic valve replacement, mitral valve repair, coronary artery bypass surgery, ascending aorta or aortic root surgery) that can be performed with minimally invasive approach either via mini-thoracotomy or mini-sternotomy.

  4. Coronary stent - Wikipedia

    en.wikipedia.org/wiki/Coronary_stent

    Coronary artery stents, typically a metal framework, can be placed inside the artery to help keep it open. However, as the stent is a foreign object (not native to the body), it incites an immune response. This may cause scar tissue (cell proliferation) to rapidly grow over the stent and cause a neointimal hyperplasia.

    en.wikipedia.org/wiki/Valve_replacement

    Current aortic valve replacement approaches include closed heart surgery, Very invasive cardiac surgery (VICS) and Very invasive, Scapulae-based aortic valve replacement. Catheter replacement of the aortic valve (called trans-aortic valve replacement or implementation [TAVR or TAVI]) is a minimally invasive option for those suffering from ...

    A heart attack during or shortly after the procedure occurs in 0.3% of cases; this may require emergency coronary artery bypass surgery. [13] Heart muscle injury characterized by elevated levels of CK-MB, troponin I, and troponin T may occur in up to 30% of all PCI procedures.

    The first uses a cardiopulmonary bypass machine, a machine which takes over the functions of the heart and lungs during surgery by circulating blood and oxygen. With the heart in cardioplegic arrest , harvested arteries and veins are used to connect across problematic regions—a construction known as surgical anastomosis .

  9. Bioresorbable stent - Wikipedia

    en.wikipedia.org/wiki/Bioresorbable_stent

    A bioresorbable stent is a tube-like device that is used to open and widen clogged heart arteries and then dissolves or is absorbed by the body. It is made from a material that can release a drug to prevent scar tissue growth. It can also restore normal vessel function and avoid long-term complications of metal stents. [1] [2]
