Changes in heart morphometric parameters over the course of a monocrotaline-induced pulmonary arterial hypertension rat model

Journal of Translational Medicine, 2020
Background Aim of this study was to assess changes in cardiac morphometric parameters at different stages of pulmonary arterial hypertension (PAH) using a monocrotaline-induced rat model. Methods Four groups were distinguished: I–control, non-PAH (n = 18)

Pathophysiology of the right ventricle and its pulmonary vascular interaction

European Respiratory Journal
The right ventricle and its stress response is perhaps the most important arbiter of survival in patients with pulmonary hypertension of many causes. The physiology of the cardiopulmonary unit and definition of right heart failure proposed in the 2018 ...

Utility of machine learning algorithms in assessing patients with a systemic right ventricle.

European Heart Journal-Cardiovascular Imaging, 2019
Aims To investigate the utility of novel deep learning (DL) algorithms in recognizing transposition of the great arteries (TGA) after atrial switch procedure or congenitally corrected TGA (ccTGA) based on routine transthoracic echocardiograms.

Correction of Double-Chambered Right Ventricle 40 Years after Pulmonary Valvuloplasty

The Thoracic & Cardiovascular Surgeon Reports, 2015
Background Double-chambered right ventricle is a partial separation of the right ventricle by pathological tissue. This anomaly is described in infants and children but can also be diagnosed in young adults.

Evaluation of Predictive Value of CT Pulmonary Angiography for Right Ventricular Failure in Patients with Pulmonary Embolism

Frontiers in Biomedical Technologies, 2023
Purpose: Right ventricle failure is a well-known complication following pulmonary thromboembolism. Although Computed Tomography Pulmonary Angiography (CTPA) findings are supposed to be a surrogate for patients’ outcome, investigations based on this ...

Assessment of left ventricle preload by transthoracic echocardiography: an easy task? [PDF]

, 2015
In sicker hearts, right atrial pressure (an estimation of right ventricle preload) are not equivalent to left atrial pressure (an estimation of left ventricle preload).

Double-chambered right ventricle [PDF]

European Heart Journal, 2007
An asymptomatic 11-year old boy with a history of spontaneously regressed right ventricle (RV) rhabdomyoma was referred to our institution for cardiovascular magnetic resonance (CMR), because a recent transthoracic echocardiography (TTE) study raised the suspicion of double-chambered RV (DCRV).

Adipokines and the Right Ventricle: The MESA-RV Study. [PDF]

, 2015
ObjectiveObesity is associated with changes in both right (RV) and left (LV) ventricular morphology, but the biological basis of this finding is not well established. We examined whether adipokine levels were associated with RV morphology and function in

Right ventricular failure and pathobiology in patients with congenital heart disease – implications for long-term follow-up

Frontiers in Pediatrics, 2013
Right ventricular dysfunction represents a common problem in patients with congenital heart defects, such as Tetralogy of Fallot or pulmonary arterial hypertension.

MEF2C regulates outflow tract alignment and transcriptional control of Tdgf1 [PDF]

, 2016
Congenital heart defects are the most common birth defects in humans, and those that affect the proper alignment of the outflow tracts and septation of the ventricles are a highly significant cause of morbidity and mortality in infants.
