Gross pathology of left ventricular hypertrophy. Left ventricle is at right in image, serially sectioned from apex to near base. There are several sets of criteria used to diagnose LVH via electrocardiography. [10] None of them are perfect, though by using multiple criteria sets, the sensitivity and specificity are increased.
Ventricular hypertrophy (VH) is thickening of the walls of a ventricle (lower chamber) of the heart. [ 1 ] [ better source needed ] Although left ventricular hypertrophy (LVH) is more common, right ventricular hypertrophy (RVH), as well as concurrent hypertrophy of both ventricles can also occur.
The diagnosis of left ventricular outflow tract obstruction is usually made by echocardiographic assessment and is defined as a peak left ventricular outflow tract gradient of ≥ 30 mmHg. [ 35 ] Another, non-obstructive variant of HCM is apical hypertrophic cardiomyopathy ( AHCM or ApHCM ), [ 37 ] also called Yamaguchi syndrome .
[1] [4] left ventricular hypertrophy (LVH) is defined as an abnormal increase in LVM, an important independent risk factor for cardiovascular morbidity and mortality. [5] [6] [7] LVM is also an independent risk factor for cardiovascular disease even within the normal limits. [8] A reduction in LVM following antihypertensive treatment or aortic ...
Chronic aortic regurgitation If the individual survives the initial hemodynamic derailment that acute AR presents, the left ventricle adapts by its eccentric hypertrophy and dilatation with a subsequent compensated volume overload. The left ventricular filling pressures will revert to normal and the individual will no longer have overt heart ...
In this condition, the walls of the left and/or right ventricles of the heart become thin and stretched. [29] In the other types, the heart's left ventricle becomes abnormally thick. Hypertrophy is usually what causes left ventricular enlargement. Hypertrophic cardiomyopathy is typically an inherited condition. [30]
As blood regurgitates into the left ventricle between each systole, volume overload ensues and the ventricular wall hypertrophies in an attempt to maintain cardiac output and blood pressure. The massive ventricle can lead to a heart weighing over 1000 grams (the weight of a normal heart is about 350 grams), referred to as cor bovinum (Latin for ...
Ventricular remodeling may include ventricular hypertrophy, ventricular dilation, cardiomegaly, and other changes. It is an aspect of cardiomyopathy, of which there are many types. Concentric hypertrophy is due to pressure overload, while eccentric hypertrophy is due to volume overload. [6]
