It is characterized by hypokinetic areas involving the free wall of the ventricle, with fibrofatty replacement of the myocardium, with associated arrhythmias often originating in the right ventricle. The nomenclature ARVD is currently thought to be inappropriate and misleading as ACM does not involve dysplasia of the ventricular wall.
In normal subjects, the left ventricular ejection fraction (LVEF) should be about 50% [9] (range, 50-80%). There should be no area of abnormal wall motion (hypokinesis, akinesis or dyskinesis). Abnormalities in cardiac function may be manifested as a decrease in LVEF and/or the presence of abnormalities in global and regional wall motion.
Due to this, and the fact that the left ventricle in normal conditions contract with a relatively invariant outer contour, [8] [9] the longitudinal strain contains the main information, while transmural strain (wall thickening) is a function of wall shortening, wall thickness and chamber diameter, while circumferential shortening is mainly a ...
The wall of the affected segments is hypo-, a-, or dyskinetic. [citation needed] The phenomenon is highly significant clinically because it usually manifests itself in the setting of chronic ischemia, that is potentially reversible by revascularisation via cardiac catheterization. The regions of myocardium are still viable and can return to ...
Myocardial perfusion imaging or scanning (also referred to as MPI or MPS) is a nuclear medicine procedure that illustrates the function of the heart muscle (). [1]It evaluates many heart conditions, such as coronary artery disease (CAD), [2] hypertrophic cardiomyopathy and heart wall motion abnormalities.
Uhl anomaly – Partial or total loss of the right ventricular wall. Ventricular septal defect (VSD) – Defect in the ventricular septum that permits blood flow between ventricles. Diseases of blood vessels – diseases of the blood vessels can be multidisciplinary in nature. For example, medical treatment of atherosclerosis tends to be ...

Uhl anomaly is a rare cardiac malformation that was first identified by Dr. Henry Uhl in 1952. It is characterized by the absence of the right ventricle (RV) myocardium, either entirely or partially, and the replacement of the RV myocardium by nonfunctional fibroelastic tissue that resembles parchment.
