Relationship between left ventricular mechanical synchrony and left ventricular systolic function: a CZT-SPECT analysis [PDF]

BMC Cardiovascular Disorders, 2022
Background CZT-SPECT has good agreement in the evaluation of mechanical synchronization compared with conventional SPECT. The aim of this study was to evaluate the correlation between left ventricular mechanical contraction synchrony and left ventricular

Left ventricular systolic function in aortic stenosis [PDF]

European Heart Journal, 1988
In aortic valve stenosis, concentric hypertrophy develops which is characterized by a reduced end-diastolic radius-to-wall thickness ratio (r/h) with an essentially normal cavity shape. As long as the product of (r/h) and LV systolic pressure remains constant, hypertrophy is appropriate.

Echocardiographic assessment of left ventricular systolic function [PDF]

Journal of Echocardiography, 2018
Left ventricular (LV) ejection fraction (LVEF) is the most validated and commonly used echocardiographic measure of systolic function. LVEF has a unique position in cardiology having severed as selection criteria for therapeutic trials that constitute the evidence base of today's treatment recommendations.

Aortic valve stenosis: Prognosis and therapy [PDF]

Vojnosanitetski Pregled, 2003
There is a long latent period in the clinical course of aortic valve stenosis in adults. Symptoms usually occur in the case of critical stenosis, when aortic orifice area is under 0.7cm2 (0.4 cm2/m2).

The architecture of the left ventricular myocytes relative to left ventricular systolic function [PDF]

European Journal of Cardio-Thoracic Surgery, 2009
Mural thickening, combined with longitudinal and circumferential shortening, and apical along with basal twisting are critical components of the left ventricular systolic deformation that contribute to ventricular ejection. It is axiomatic that the spatial alignment of the actively contracting aggregates of myocytes must play a major role in the ...

Relation of atrial natriuretic peptides to left ventricular systolic and diastolic function in heart failure [PDF]

, 2000
Background: Plasma concentrations of atrial natriuretic peptides are correlated with atrial pressures, as are left ventricular ejection fraction and left ventricular filling abnormalities. Aims: This study investigated the relation of atrial natriuretic

Left ventricular systolic function in dogs with pulmonic stenosis [PDF]

Veterinary World, 2020
Background and Aim: Pulmonic stenosis (PS) is the most common congenital heart disease in dogs. This condition causes right ventricle (RV) overload and disrupts overall systolic function.
