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

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).

Evaluation of right ventricular function during liver transplantation with transesophageal echocardiography.

PLoS ONE, 2022
BackgroundThe pathophysiology of advanced liver cirrhosis may induce alterations in the circulatory system that may be challenging for the anesthesiologist to manage intraoperatively, and perioperative cardiovascular events are associated with worse ...

Right Ventricular Function, Peripheral Edema, and Acute Kidney Injury in Critical Illness

Kidney International Reports, 2017
The cardiorenal syndrome generally focuses on left ventricular function, and the importance of the right ventricle as a determinant of renal function is described less frequently. In a cohort of critically ill patients with echocardiographic measurements

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.

Right Ventricular Segmentation from Short- and Long-Axis MRIs via Information Transition [PDF]

arXiv, 2021
Right ventricular (RV) segmentation from magnetic resonance imaging (MRI) is a crucial step for cardiac morphology and function analysis. However, automatic RV segmentation from MRI is still challenging, mainly due to the heterogeneous intensity, the complex variable shapes, and the unclear RV boundary. Moreover, current methods for the RV segmentation

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 ...

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

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 ...
