Transthoracic three-dimensional echocardiography for the assessment of straddling tricuspid or mitral valves [PDF]
, 2008 Background The advent of 3D echocardiography has provided a technique which, potentially, could afford significant additional information over conventional cross-sectional echocardiography in the assessment of patients with straddling atrioventricular ...

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).

By-passing the Right Ventricle.
Experimental Biology and Medicine, 1949 Summary1. An anastomosis was made between the right atrial appendage and the main pulmonary artery.2. In acute experiments, the venous pressure was demonstrated to drive venous return through the lungs without benefit of the pumping action of the right ventricle.3. In chronic experiments, the anastomosis acts similarly to a tricuspid insufficiency.

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

Semi-Supervised Segmentation of Multi-vendor and Multi-center Cardiac MRI using Histogram Matching [PDF]
IEEE Conference on Signal Processing and Communications
applications (SIU 2021), 2023 Automatic segmentation of the heart cavity is an essential task for the diagnosis of cardiac diseases. In this paper, we propose a semi-supervised segmentation setup for leveraging unlabeled data to segment Left-ventricle, Right-ventricle, and Myocardium. We utilize an enhanced version of residual U-Net architecture on a large-scale cardiac MRI dataset.

The vulnerable right ventricle
Current Opinion in Pediatrics, 2015 The right ventricle (RV) is uniquely at risk in many patients with repaired or palliated congenital heart disease (CHD) such as tetralogy of Fallot, corrected transposition, single right ventricle, and in those with pulmonary hypertension. These patients live with abnormal cardiac loading conditions throughout their life, predisposing them to right ...

Histone deacetylase adaptation in single ventricle heart disease and a young animal model of right ventricular hypertrophy. [PDF]
, 2017 BackgroundHistone deacetylase (HDAC) inhibitors are promising therapeutics for various forms of cardiac diseases. The purpose of this study was to assess cardiac HDAC catalytic activity and expression in children with single ventricle (SV) heart disease ...

Journal of The Indian Academy of Echocardiography & Cardiovascular Imaging, 2018 Right Ventricle (RV) has been treated as the neglected cardiac chamber for a long time. Advent of cardiac MRI and advancements in echocardiography have facilitated the understanding of RV structure and function and elucidated its role in management and prognosis of various cardiac ailments.

Don't Forget the Right Ventricle [PDF]
Journal of Cardiothoracic and Vascular Anesthesia, 2020 In their recent article, González-Tallada et al. demonstrated an incidence of myocardial injury after noncardiac surgery (MINS) in 27.3% of patients undergoing thoracic surgery.1 MINS was defined as a postoperative troponin I level >0.04 ng/mL (>99th percentile) without evidence of a nonischemic cause of troponin I elevation.
