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 ...

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

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 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 ...

Improvement of left ventricular systolic function after intervention on right ventricular hemodynamics

Annals of Pediatric Cardiology
Background: The importance of right–left ventricular interactions is increasingly recognized in patients with congenital heart disease. Interventions to improve right ventricular volume/pressure overloading may result in improvement of left ventricular ...

RaMBat: Accurate identification of medulloblastoma subtypes from diverse data sources with severe batch effects

Molecular Oncology, EarlyView.
To integrate multiple transcriptomics data with severe batch effects for identifying MB subtypes, we developed a novel and accurate computational method named RaMBat, which leveraged subtype‐specific gene expression ranking information instead of absolute gene expression levels to address batch effects of diverse data sources.

Relation Between QRS Duration, Right Ventricular Func-tion and Left Ventricular Dyssinchrony in Patients After Surgical Correction of Tetralogy Fallot

Majalah Kardiologi Indonesia, 2013
Background. QRS duration has long been established as a strong predic-tor of sudden cardiac death in patients after surgical correction of Tetral-ogy of Fallot (TOF).
