  2. Deep hypothermic circulatory arrest - Wikipedia

    en.wikipedia.org/wiki/Deep_hypothermic...

    After surgery is completed during the period of cold circulatory arrest, these steps are reversed. The brain and heart naturally resume activity as warming proceeds. The first activity of the warming heart is sometimes ventricular fibrillation requiring cardioversion to re-establish a normal beating rhythm. [42]

  3. Hypokalemia - Wikipedia

    en.wikipedia.org/wiki/Hypokalemia

    Mild hypokalemia is often without symptoms, although it may cause elevation of blood pressure, [6] and can provoke the development of an abnormal heart rhythm. Severe hypokalemia, with serum potassium concentrations of 2.5–3 meq/L (Nl: 3.5–5.0 meq/L), may cause muscle weakness, myalgia, tremor, and muscle cramps (owing to disturbed function ...

  4. Coronary artery bypass surgery - Wikipedia

    en.wikipedia.org/wiki/Coronary_artery_bypass_surgery

    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.

  5. Cardiac surgery - Wikipedia

    en.wikipedia.org/wiki/Cardiac_surgery

    Cardiac surgery, or cardiovascular surgery, is a surgery on the heart or great vessels performed by cardiac surgeons.It is often used to treat complications of ischemic heart disease (for example, with coronary artery bypass grafting); to correct congenital heart disease; or to treat valvular heart disease from various causes, including endocarditis, rheumatic heart disease, [1] and ...

  6. Minimally invasive direct coronary artery bypass surgery

    en.wikipedia.org/wiki/Minimally_invasive_direct...

    Minimally invasive direct coronary artery bypass (MIDCAB) is a surgical treatment for coronary heart disease that is a less invasive method of coronary artery bypass surgery (CABG). [1] MIDCAB gains surgical access to the heart with a smaller incision than other types of CABG.

  7. Minimally invasive cardiac surgery - Wikipedia

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

    This procedure makes heart surgery possible for patients who were previously considered too high risk for traditional surgery due to age or medical history. [ 5 ] [ 6 ] Patients referred for this procedure may have coronary artery disease (CAD); aortic, mitral or tricuspid valve diseases; or previous unsuccessful stenting.

  8. Off-pump coronary artery bypass - Wikipedia

    en.wikipedia.org/wiki/Off-pump_coronary_artery...

    Off-pump coronary artery bypass (OPCAB), or beating-heart surgery, is a form of coronary artery bypass graft (CABG) surgery performed without cardiopulmonary bypass (heart-lung machine) as a treatment for coronary heart disease. It was primarily developed in the early 1990s by Dr. Amano Atsushi.

  9. Afterdepolarization - Wikipedia

    en.wikipedia.org/wiki/Afterdepolarization

    Afterdepolarization is commonly a consequence of myocardial infarction, cardiac hypertrophy, or heart failure. [1] It may also result from congenital mutations associated with calcium channels and sequestration. [2]
