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 ...

Sodium leak through K2P potassium channels and cardiac arrhythmia, an emerging theme. [PDF]

, 2017
In this issue of EMBO Molecular Medicine, Decher et al (2017) identify a point mutation in the K2P2 (TREK‐1) potassium (K+) channel that changes function in just those ways expected to predispose to right ventricular outflow tract (RVOT) ventricular

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.

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

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).

Arterial switch for pulmonary venous obstruction complicating mustard procedure [PDF]

, 1995
Two patients underwent an arterial switch procedure for the relief of severe pulmonary venous obstruction complicating a Mustard procedure. Without preparatory pulmonary banding, both patients had adequate left ventricular function due to secondary ...

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 ...

Association of tricuspid annular plane systolic excursion (TAPSE) with survival time in Boxer dogs with ventricular arrhythmias [PDF]

, 2015
BACKGROUND: Tricuspid annular plane systolic excursion (TAPSE) is a useful estimate of right ventricular function in humans. Reference intervals for dogs have been generated, but the value of measuring TAPSE in other diseases, or investigating the ...
