Prevalence, clinical characteristics, and outcomes associated with eccentric versus concentric left ventricular hypertrophy in heart failure with preserved ejection fraction.
In this blog we describe left ventricular hypertrophy (LVH) and identify the different categories of concentric, eccentric and concentric remodeling.
Whether modifications of LV geometry from concentric to eccentric are beneficial beyond the reduction of LV mass has been debated; however, the conclusion has been, in general, that concentric LV hypertrophy is also characterized by greater LV mass than eccentric LV hypertrophy; therefore, these 2 features (ie, concentric geometry and LV ...
This eccentric hypertrophy creates a dilated ventricular chamber with relative wall thinning. In contrast, concentric hypertrophy is more often associated with chronic pressure overload states like hypertension or aortic stenosis.
Patients with LVH (LVM/body surface area ≥116 and ≥96 g/m 2 in men and woman, respectively) were divided into 4 groups—concentric nondilated (increased M/EDV, normal EDV), eccentric dilated (increased EDV, normal M/EDV), concentric dilated (increased M/EDV and EDV), and eccentric nondilated (normal M/EDV and EDV)—and compared with ...
Concentric left ventricular hypertrophy is an abnormal increase in left ventricular myocardial mass caused by chronically increased workload on the heart, most commonly resulting from pressure overload-induced by arteriolar vasoconstriction as occurs in, chronic hypertension or aortic stenosis.
Concentric hypertrophy is associated with increased left ventricular wall thickness whereas eccentric hypertrophy is characterized by dilatation of the left ventricular chamber; however, there occurs a general increase in the overall size of cardiomyocytes under both conditions.
