| myocardial necrosis | Irreversible destruction of myocardial (heart muscle) cells. (27 Sep 1997) |
|---|---|
| myocardial perfusion imaging | <radiology> (thallium scanning) thallium (Tl) 201, acts as potassium analog, dose 2.0 - 3.0 mCi at peak exercise, 4% of injected dose reaches myocardium, imaging: exercise (1-5 min), redistribution (3-4 hrs), views: anterior, LAO 45', left lateral, interpretation: normal, reversible abnormalitymost likely to be exercise-induced ischemia, nonreversible abnormalitymost likely to be prior myocardial infarction, reverse redistribution most likely to be normal areas wash out faster, lung activity most likely to be LV failure during exercise see also: dipyridamole test, nuclear cardiology (12 Dec 1998) |
| myocardial reperfusion | Generally, restoration of blood supply to heart tissue which is ischemic due to decrease in normal blood supply. The decrease may result from any source including atherosclerotic obstruction, narrowing of the artery, or surgical clamping. Reperfusion can be induced to treat ischemia. Methods include chemical dissolution of an occluding thrombus, administration of vasodilator drugs, angioplasty, catheterization, and artery bypass graft surgery. However, it is thought that reperfusion can itself further damage the ischemic tissue, causing myocardial reperfusion injury. (12 Dec 1998) |
| myocardial reperfusion injury | Functional, metabolic, or structural changes in ischemic heart muscle thought to result from reperfusion to the ischemic areas. Changes can be fatal to muscle cells and may include oedema with explosive cell swelling and disintegration, sarcolemma disruption, fragmentation of mitochondria, contraction band necrosis, enzyme washout, and calcium overload. Other damage may include haemorrhage and ventricular arrhythmias. One possible mechanism of damage is thought to be oxygen free radicals. Treatment currently includes the introduction of scavengers of oxygen free radicals, and injury is thought to be prevented by warm blood cardioplegic infusion prior to reperfusion. (12 Dec 1998) |
| myocardial revascularization | The restoration of blood supply to the myocardium. (12 Dec 1998) |
| myocardial rigor mortis | Irreversible contraction of the left ventricle of the heart as a complication seen in the early period of cardiopulmonary bypass and now avoided by appropriate cardioplegic solutions. Synonym: myocardial rigor mortis, stone heart. (05 Mar 2000) |
| myocardial stunning | Prolonged dysfunction of the myocardium after a brief episode of severe ischemia, with gradual return of contractile activity. It occurs frequently, both in the experimental laboratory and in clinical medicine. Since stunned myocardium occurs adjacent to necrotic tissue after prolonged coronary occlusion, many myocardial infarcts may be a mixture of necrotic and stunned tissue. (12 Dec 1998) |
| myocardiograph | An instrument composed of a tambour with recording lever attachment, by means of which a tracing is made of the movements of the heart muscle. Origin: myo-+ G. Kardia, heart, + grapho, to record (05 Mar 2000) |
| myocardiopathy | Synonym: cardiomyopathy. Origin: myocardium + G. Pathos, suffering (05 Mar 2000) |
| myocardiorrhaphy | Suture of the myocardium. Origin: myocardium + G. Rhaphe, suture (05 Mar 2000) |
| myocarditic | Related to myocarditis (adjective). (05 Mar 2000) |
| myocarditis | <cardiology, pathology> Inflammation of the myocardium, inflammation of the muscular walls of the heart. Origin: Gr. Kardia = heart (18 Nov 1997) |
| myocardium | <anatomy> A term used to describe the middle layer of the heart wall (heart muscle). (27 Sep 1997) |
| myocardosis | An obsolete term for a condition marked by symptomatic signs of cardiac trouble without any discoverable pathologic lesion and for any degenerative condition of the heart muscle except myofibrosis. (05 Mar 2000) |
| myocele | 1. Protrusion of muscle substance through a rent in its sheath. Origin: myo-+ G. Kele, hernia 2. The small cavity that appears in somites. Synonym: somite cavity. Origin: myo-+ G. Koilia, a cavity (05 Mar 2000) |
