Right ventricular (RV) diastolic dysfunction is an important indicator for the assessment of heart failure. Abnormalities in RV diastolic function underlie many pathologies. However, the underlying mechanisms remain poorly described, because the term is used to describe many variants in diastolic pathophysiology and function. Since the right ventricle is coupled to the pulmonary circulation wit...

the right ventricle (rv) is a complex structure with abstruse function that reveals important differences when compared to the left ventricle (lv), so it cannot be described as a simple geometric form and achromatic physiology. as an inference from this fact, in the present review, we aim to describe rv structure including the embryology, anatomy, and physiology and present a functional, hemody...

Only in recent years has the right ventricle (RV) function become appreciated to be equally important to the left ventricle (LV) function to maintain cardiac output. Right ventricular failure is, irrespectively of the etiology, associated with impaired exercise tolerance and poor survival. Since the anatomy and physiology of the RV is distinctly different than that of the LV, its adaptive mecha...

PURPOSE To investigate right ventricle function in successfully reperfused ST elevated myocardial infarction (STEMI) and to compare reperfusion strategies. METHODS From January 2007 to August 2008, 33 patients with anterior myocardial infarction (MI) and 48 patients with non-anterior myocardial infarction were enrolled in this study. Patients were treated with thrombolytic therapy (TT) or pri...

The present study was undertaken to elucidate pathophysiological and pharmacological alterations in the right ventricle in monocrotaline-administered (MCT) rats. Examination of tissue weights of the MCT and age-matched control (CON) rats indicated the right ventricular (RV) hypertrophy until 8 weeks after a single subcutaneous administration of 60 mg/kg MCT. Apparent fibrosis in the right ventr...

background: the right ventricular (rv) dyssynchrony has not been studied extensively and the existing literature has established the effect of cardiac resynchronization therapy (crt) on the left ventricular (lv) dyssynchrony, but there is a dearth of data on the effect of crt on the forgotten ventricle . we sought to evaluate the presence of mechanical right ventricular dyssynchrony in patients...

objectives in this study, besides studying the rv function in ssc patients, attempts have been made to find a new possible noninvasive echocardiographic test for early diagnosis of systolic failure as a pah complication. methods 30 patients with at least a 2-year history of diffuse ssc confirmed by an expert rheumatologist were enrolled in this study. all the patients underwent transthoracic ec...

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 ...

Sepsis could produce myocardial depression and typically it affects the left ventricle (LV). Sepsis could also affect right ventricle (RV), in addition to the interdependence with LV. RV pressure may be elevated secondary to pulmonary vasoconstriction, leading to RV dysfunction. Unlike LV, RV is poorly prepared to compensate for acute overload. Aggressive volume replacement may be vital to main...

UNLABELLED In patients with pulmonary hypertension (PH) the right ventricular (RV)-to-left ventricular (LV) ratio of fatty acid uptake is reduced. In animal studies, such a finding was combined with an increased glucose uptake in RV myocardium. The aim of this study was to measure the metabolic rates of glucose uptake for the RV and LV myocardium in patients in relationship to parameters of RV ...
