  2. Coronary artery bypass surgery - Wikipedia

    en.wikipedia.org/wiki/Coronary_artery_bypass_surgery

    Snares and tapes are used to facilitate exposure. The aim is to avoid distal ischemia caused by blockage of the vessel supplying distal portions of the left ventricle, so usually LITA to LAD is the first to be anastomosed and others follow. For the anastomosis, a fine tube blowing humidified CO 2 keeps the surgical field clean of blood. Also, a ...

  3. Left anterior descending artery - Wikipedia

    en.wikipedia.org/wiki/Left_anterior_descending...

    The LAD gives off two types of branches: septals and diagonals. Septals originate from the LAD at 90 degrees to the surface of the heart, perforating and supplying the anterior 2/3 of the interventricular septum. Diagonals run along the surface of the heart and supply the lateral wall of the left ventricle and the anterolateral papillary muscle.

  4. Restenosis - Wikipedia

    en.wikipedia.org/wiki/Restenosis

    The term "binary" means that patients are placed in 2 groups, those who have ≥50% stenosis and those who have <50% stenosis. Binary restenosis is an epidemiological method of analyzing percent diameter stenosis for observing not only an individual patient, but also performing statistical techniques on a group of patients to determine averages ...

  5. Coronary catheterization - Wikipedia

    en.wikipedia.org/wiki/Coronary_catheterization

    Since the late 1970s, building on the pioneering work of Charles Dotter in 1964 and especially Andreas Gruentzig starting in 1977, coronary catheterization has been extended to therapeutic uses: (a) the performance of less invasive physical treatment for angina and some of the complications of severe atherosclerosis, (b) treating heart attacks ...

  6. Coronary artery disease - Wikipedia

    en.wikipedia.org/wiki/Coronary_artery_disease

    Treatment involves the same measures as prevention. [10] [22] Additional medications such as antiplatelets (including aspirin), beta blockers, or nitroglycerin may be recommended. [10] Procedures such as percutaneous coronary intervention (PCI) or coronary artery bypass surgery (CABG) may be used in severe disease.

  7. Angioplasty - Wikipedia

    en.wikipedia.org/wiki/Angioplasty

    The LAD, as is usual, has two large diagonal branches, which arise at the centre-top of the image and course toward the centre-right of the image. A coronary angioplasty is a therapeutic procedure to treat the stenotic (narrowed) coronary arteries of the heart found in coronary heart disease . [ 1 ]

  8. Wellens' syndrome - Wikipedia

    en.wikipedia.org/wiki/Wellens'_syndrome

    Wellens' syndrome is an electrocardiographic manifestation of critical proximal left anterior descending (LAD) coronary artery stenosis in people with unstable angina. Originally thought of as two separate types, A and B, it is now considered an evolving wave form, initially of biphasic T wave inversions and later becoming symmetrical, often ...

  9. Aortic stenosis - Wikipedia

    en.wikipedia.org/wiki/Aortic_stenosis

    Aortic valve repair or aortic valve reconstruction describes the reconstruction of both form and function of the native and dysfunctioning aortic valve. Most frequently it is applied for the treatment of aortic regurgitation. It can also become necessary for the treatment of an aortic aneurysm, less frequently for congenital aortic stenosis. [53]
