HYPERTROPHIC CARDIOMYOPATHY
filling prevents the heart from pumping enough blood, especially during exercise. Although HCM can involve both lower chambers, it usually affects the main pumping chamber (left ventricle) with thickening of the septum (wall separating the pumping chambers), posterior wall or both. With hypertrophic obstructive cardiomyopathy (HOCM), the muscle ...

Hypertrophic Cardiomyopathy Guide linic.org
Thickening of the heart muscle (myocardium) occurs most commonly at the septum. The septum is the muscular wall that separates the left and right side of the heart. Problems occur when the septum between the heart’s lower chambers, or ventricles, is thickened. The thickened septum may cause a narrowing that can block or reduce the blood

Differential diagnosis of thickened myocardium: an ...
myocardial wall thickening caused by pressure/volume over-load, infiltrative disorders, athlete ’s heart or neoplastic infil-tration [2–5]. For HCM diagnosis, international guidelines advocate using a wall thickness cut-off of 15 mm in one or more myocardial segments, measured by any imaging tech-nique [6, 7].

Hypertrophic cardiomyopathy is a disorder of the muscle cells of the heart, producing overly thick areas in the chamber walls. The most commonly affected areas of the heart are the apex of the heart and the central column of muscle (called the septum) with or without thickening of the posterior wall …

Understanding Feline Cardiomyopathy
This thickening causes the heart to not be able to relax normally when filling with blood. Over time this can lead to elevated pressures within the heart and ultimately congestive heart failure (fluid accumulation). Some cats with HCM will also have an obstruction to blood flow that is associated with the thickened muscle wall that can cause a ...

The muscle surrounding the left ventricle is the area commonly affected. Sometimes the muscle around the right ventricle is also affected. The degree of thickening may vary in different places. For example, the wall dividing the right and left ventricle (the septum) is often the area with the greatest thickening. In about 1 in 4 people the ...

the typical thickening of the heart wall is usually higher than 40% [10]. It is important to note that the wall thickening is not determined solely by the incompressibility of the myocardium. In the schematic of Fig 1, if the LV could dilate circumfere ntially, a WT of 10% would satisfy the incompressibility but results in …

and particularly the septum (area of muscle in the middle of the heart, which separates the right and left sides). However, it can also affect the right ventri-cle. The average thickness of the left ventricle wall in an adult is 12mm, but in HCM the thickness is 15mm or more. The thickening of the muscle …
