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 patients with RV myocardial infarction, pu...

BACKGROUND The right ventricle (RV) has an essential function in cardiovascular physiology and pathology. Currently, it is gaining an increasing interest given its recognized role in many cardiovascular conditions. However, echocardiographic assessment of the RV in daily practice is frequently based on qualitative estimation, and it has been regarded as a neglected chamber. OBJECTIVE We sough...

OBJECTIVES Right ventricular (RV) exercise contractile reserve (RVECR), its phenotypes, and its functional correlates are among the unresolved issues with regard to the role of the right ventricle in heart failure (HF) syndrome, and understanding these issues constitutes the objective of this study. BACKGROUND Although the role of the right ventricle in HF syndrome might be fundamental, the p...

Right ventricle (RV) dysfunction is a key outcome determinant and a leading cause of death for patients with chronic thromboembolic pulmonary hypertension (CTEPH). In this report, we followed the 5-year clinical journey of a patient with CTEPH. The tricuspid pressure gradient was significantly increased in the early phase of CTEPH and "normalized" at the late phase of this patient's clinical jo...

Background Severe right ventricular dysfunction (RVD) is an important prognostic parameter in dilated cardiomyopathy (DCM). The relationship between myocardial fibrosis of the left ventricle (LV) and particularly the septum and right ventricular (RV) function remains poorly understood. We sought to investigate this relationship in a large cohort of DCM patients using cardiovascular magnetic res...

Pulmonary arterial hypertension (PAH) is an incurable disease characterized by an increase in pulmonary arterial pressure due to pathological changes to the pulmonary vascular bed. As a result, the right ventricle (RV) is subject to an increased afterload and undergoes multiple changes, including a decrease in capillary density. All of these dysfunctions lead to RV failure. A number of studies ...

background: moderate non-organic tricuspid regurgitation (tr) concomitant with coronary artery disease is not uncommon. whether or not tr improves after pure coronary artery bypass grafting (cabg), however, is unclear.   the aim of this study was to evaluate the effect of isolated cabg on moderate non-organic tr. methods: this study recruited 50 patients (40% female, mean age: 65.38 ± 8.01 year...

BACKGROUND Right ventricular (RV) volume and function are important diagnostic and prognostic factors in dogs with primary or secondary right-sided heart failure. The complex shape of the right ventricle and its retrosternal position make the quantification of its volume difficult. For that reason, only few studies exist, which deal with the determination of RV volume parameters. In human medic...

This study aimed to demonstrate that congenital diaphragmatic hernia (CDH) results in vascular abnormalities that are directly associated with the severity of pulmonary hypoplasia and hypertension. These events increase right ventricle (RV) afterload and may adversely affect disease management and patient survival. Our objective was to investigate cardiac function, specifically right ventricula...

Background The right ventricle (RV) is not designed to sustain high pressure leading to failure. There are no current medications to help RV contraction, so further information is required on adaption of the RV to such hypertension. Methods The Right Ventricle in Children (RVENCH) study assessed infants with congenital heart disease undergoing cardiac surgery with hypertensive RV. Clinical an...
