Altered microRNA and target gene expression related to Tetralogy of Fallot [PDF]

, 2019
MicroRNAs (miRNAs) play an important role in guiding development and maintaining function of the human heart. Dysregulation of miRNAs has been linked to various congenital heart diseases including Tetralogy of Fallot (TOF), which represents the most ...

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

Evidence that conflict regarding size of haemodynamic response to interventricular delay optimization of cardiac resynchronization therapy may arise from differences in how atrioventricular delay is kept constant. [PDF]

, 2014
Aims: Whether adjusting interventricular (VV) delay changes haemodynamic efficacy of cardiac resynchronization therapy (CRT) is controversial, with conflicting results.

How prostacyclin therapy improves right ventricular function in pulmonary arterial hypertension

European Respiratory Journal, 2017
Within recent years, right ventricular (RV) function has been recognised as a major determinant of outcome in pulmonary arterial hypertension (PAH) [1, 2].

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 ...

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 ...
