Background/Aims: It has previously been shown that permanent right ventricular (RV) apical pacing may lead to worsening of cardiac function due to associated electrical and mechanical dyssynchrony. Cardiac resynchronization therapy (CRT) or high septal RV pacing could be beneficial to prevent patients from these negative effects. Methods/Results: In this single center clinical study 164 patient...

OBJECTIVES To evaluate the contribution of breastfeeding to Rotavirus (RV)-induced antigenemia and/or RNAemia and disease severity in Indian children (<2 yrs age). METHODS Paired stool and serum samples were collected from (a) hospitalized infants with diarrhea (n = 145) and (b) healthy control infants without diarrhea (n = 28). Stool RV-antigen was screened in both groups by commercial rapid...

Right ventricular (RV) weight increases dependent on time after myocardial infarction (MI) and on MI size. The sequential changes in RV volume and hemodynamics and their relations to left ventricular (LV) remodeling after MI are unknown. We therefore examined the time course of RV remodeling in rats with LV MI. MI was produced by left coronary artery ligation. Four, eight, and sixteen weeks lat...

BACKGROUND & OBJECTIVE Rubella virus (RV) is one of the leading causes of childhood blindness in India. In this study we applied an optimized nested reverse transcription polymerase chain reaction (nRT-PCR) to detect RV in clinical specimens. METHODS nRT-PCR was optimized using total RNA extracted from standard strain of RV using nested sets of primers specific for E1 open reading frame. nRT-...

BACKGROUND AND OBJECTIVES Right ventricle (RV) remodeling can determine tricuspid valve (TV) geometry and the severity of functional tricuspid regurgitation (TR). SUBJECTS AND METHODS In 53 patients with various degrees of functional TR and in sinus rhythm, RV and TV geometries were analyzed using real-time 3-dimensional echocardiography, including tenting angles of 3 leaflets, septal-lateral...

By comparing three expression vectors for the rabies virus (Rv) minigenome, we show that the characteristic of the Rv RNA is important for efficient rescue despite its not being crucial for replication. Moreover, we show that the coexpression of the viral proteins from helper Rv and Mokola virus could rescue the Rv minigenome while Rv-related European bat lyssavirus 1 could not, suggesting that...

Objective To compare tissue-velocity MRI (TV-MRI) and tissue Doppler imaging (TDI) to assess regional right ventricular (RV) diastolic performance at the RV free wall (RVFW) and at the RV outflow tract (RVOT) in patients with corrected Tetralogy of Fallot (cToF) and in healthy controls. To compare regional diastolic velocities and performance of the RV between cToF patients and controls. To inv...

Right ventricular (RV) function is an important determinant of prognosis in congenital heart diseases, pulmonary hypertension, and heart failure. Preventive sildenafil treatment has been shown to enhance systolic RV function and improve exercise capacity in a model of fixed RV pressure load. However, it is unknown whether sildenafil has beneficial effects when treatment is started in establishe...

INTRODUCTION Right ventricular (RV) function has increasingly being recognized as an important predictor for morbidity and mortality in patients with pulmonary arterial hypertension (PAH). The increased RV after-load increase RV work in PAH. We used time-resolved 3D phase contrast MRI (4D flow MRI) to derive RV kinetic energy (KE) work density and energy loss in the pulmonary artery (PA) to bet...

The aim of this study was to use magnetic resonance imaging (MRI) to classify the morphological changes and remodeling of the right ventricle (RV) that occur in different clinical situations and that have an impact on RV function. Most literature has traditionally focused on the left ventricle (LV) and as a result, few studies analyze RV behavior and remodeling. The study evaluated all cardiac ...
