Echocardiographic Evaluation of Right Ventricular Function [PDF]

European Journal of Echocardiography, 2002
To allow optimal patient management an ideal measure of right ventricular performance should give an accurate objective assessment of function, be practicable in everyday clinical use and provide accurate prognostic information. This review will provide the practising clinician with an understanding of the advantages and disadvantages of the available ...

Right Ventricular Plasticity and Functional Imaging [PDF]

Pulmonary Circulation, 2012
Right ventricular (RV) function is a strong independent predictor of outcome in a number of distinct cardiopulmonary diseases. The RV has a remarkable ability to sustain damage and recover function which may be related to unique anatomic, physiologic, and genetic factors that differentiate it from the left ventricle. This capacity has been described in

Beta-blockers, left and right ventricular function, and in-vivo calcium influx in muscular dystrophy cardiomyopathy.

PLoS ONE, 2013
Beta-blockers are used to treat acquired heart failure in adults, though their role in early muscular dystrophy cardiomyopathy is unclear. We treated 2 different dystrophic mouse models which have an associated cardiomyopathy (mdx: model for Duchenne ...

MECHANISMS OF RIGHT VENTRICULAR FAILURE AND BIVENTRICULAR MECHANICAL CIRCULATORY SUPPORT

Вестник трансплантологии и искусственных органов, 2014
The paper presents a review of the problems of mechanical circulatory support with left ventricular bypass in total cardiac failure. Dysfunction of right ventricular defines the high mortality on left ventricular device.

Evaluation of the right ventricular function in dogs with brachycephalic syndrome before and after rhinoplasty

Brazilian Journal of Veterinary Medicine, 2022
Brachycephalic dogs are usually affected by primary and secondary anatomical changes in the airways that contribute to the brachycephalic syndrome. Chronically, these changes contribute to an increase in pulmonary arterial pressure and right cardiac ...

Acute left ventricular dysfunction secondary to right ventricular septal pacing in a woman with initial preserved contractility: a case report

Journal of Medical Case Reports, 2011
Introduction Right ventricular apical pacing-related heart failure is reported in some patients after long-term pacing. The exact mechanism is not yet clear but may be related to left ventricular dyssynchrony induced by right ventricular apical pacing ...

Partitioning the Right Ventricle Into 15 Segments and Decomposing Its Motion Using 3D Echocardiography-Based Models: The Updated ReVISION Method

Frontiers in Cardiovascular Medicine, 2021
Three main mechanisms contribute to global right ventricular (RV) function: longitudinal shortening, radial displacement of the RV free wall (bellows effect), and anteroposterior shortening (as a consequence of left ventricular contraction).

Right Heart Size and Right Ventricular Reserve in Pulmonary Hypertension: Impact on Management and Prognosis

Diagnostics, 2020
Various parameters reflecting right heart size, right ventricular function and capacitance have been shown to be prognostically important in patients with pulmonary hypertension (PH).

Subtle right ventricular dysfunction in asymptomatic chronic heavy cigarette smokers: a speckle tracking case-control study

The Egyptian Heart Journal, 2021
Background Chronic heavy cigarette smoking can affect the right ventriclular function. The standard echocardiography may not show early right ventricular functional changes, and a more sensitive measure is needed. The aim of this work was to evaluate the

Right ventricular dyssynchrony in patients with pulmonary hypertension is associated with disease severity and functional class

Cardiovascular Ultrasound, 2005
Background Abnormalities in right ventricular function are known to occur in patients with pulmonary arterial hypertension. Objective Test the hypothesis that chronic elevation in pulmonary artery systolic pressure delays mechanical activation of the ...
