Right ventricular (RV) involvement after acute myocardial infarction (MI) carries an adverse prognosis, but in the majority of patients RV function recovers fully over time.1 It is believed that the lower oxygen requirement of the RV and higher collateral flow make the RV more resistant to ischemia. In the absence of infarction, myocardial ischemia leads to intracellular and subsequently extrac...

Viruses are the leading cause for hospitalization due to gastroenteritis worldwide. Group A rotaviruses (RV) are the most prevalent and are assorted in glycoproteins (G) and protease sensitive (P) dual genotypes based on polymorphic genes that encode the external VP7 and VP4 capsid proteins, respectively. Noroviruses (NoV) have increasingly answered by sporadic gastroenteritis. This study aimed...

BACKGROUND The role of echocardiographic right ventricular (RV) dysfunction in predicting clinical outcome in clinically stable patients with pulmonary embolism (PE) is undefined. In this study, we assessed the prevalence and clinical outcome of normotensive patients with RV dysfunction among a broad spectrum of PE patients. METHODS AND RESULTS This prospective clinical outcome study included...

BACKGROUND Our study compares new single beat 3D echocardiography (sb3DE) to cardiovascular magnetic resonance imaging (CMR) for the measurement of right ventricular (RV) dimension and function immediately after a 30 km run. This is to validate sb3DE against the "gold standard" CMR and to bring new insights into acute changes of RV dimension and function after endurance exercise. METHODS 21 n...

Adaptation of the right ventricle (RV) to increased afterload is crucial for survival in pulmonary hypertension (PH), but it is challenging to assess RV function and identify associated molecular mechanisms. The aim of the current study was to analyze the relationship between invasive and noninvasive parameters of RV morphology and function and associated molecular changes. The response of mice...

BACKGROUND In current cardiology practice, the importance of acute cardiorenal syndrome (CRS) in determining the outcome of patients with acute coronary syndrome (ACS) is well recognized. Certain groups of ACS patients are at higher risk of developing CRS. Data on the association between right ventricular (RV) functions and CRS after acute myocardial infarction (AMI) are scarce. The purpose of ...

The right ventricular (RV) response to exercise was assessed in 32 patients with angiographically documented coronary artery disease and in 14 normal controls without cardiopulmonary disease. The relationships between exercise RV reserve, exercise left ventricular (LV) reserve, and the presence of proximal right coronary stenosis were also evaluated. RV and LV ejection fractions were determined...

Background Right ventricular (RV) dysfunction is an important predictor of long-term outcome in heart failure patients undergoing surgical ventricular restoration (SVR). RV assessment is therefore a pivotal step in the selection of patient candidates for SVR and during follow up. While the impact of SVR on left ventricle (LV) is currently described in terms of both functional and morphological ...

Previous studies in Jeddah, western Saudi Arabia, showed rotavirus (RV) prevalence around 40% in pediatric inpatients with gastroenteritis (GE) with a maximum level during cooler months. Currently, there are no data on impact of rotavirus vaccine (RVV) on RV-GE in Saudi Arabia. Therefore, this study was conducted to assess impact of RVV on incidence and severity of RV-GE in hospitalized pediatr...
