Clinical relevance of right ventricular diastolic stiffness in pulmonary hypertension.
Right ventricular (RV) diastolic stiffness is increased in pulmonary arterial hypertension (PAH) patients. We investigated whether RV diastolic stiffness is associated with clinical progression and assessed the contribution of RV wall thickness to RV systolic and diastolic stiffness. Using single-beat pressure-volume analyses, we determined RV end-systolic elastance (Ees), arterial elastance (E...
متن کاملDescribing right ventricular function.
In pulmonary hypertension and other conditions, such as acute respiratory distress syndrome and left heart failure, right ventricular dysfunction is a prognostic determinant. Therefore, functional parameters pertaining to the right heart alone, i.e. independent of its loading conditions, should be used to quantify right ventricular disease progression and the results of treatment. Two methods t...
متن کاملPleural effusion as a cause of right ventricular diastolic collapse.
BACKGROUND We hypothesized, after seeing several suggestive clinical examples, that a process leading to a large bilateral pleural effusion in the presence of an otherwise insignificant pericardial effusion could result in right ventricular diastolic collapse (RVDC) as seen by two-dimensional echocardiography. This noninvasive marker for hemodynamically significant cardiac tamponade occurs when...
متن کاملEffect of right ventricular pressure on the end-diastolic left ventricular pressure-volume relationship before and after chronic right ventricular pressure overload in dogs without pericardia.
We studied the effect of chronic right ventricular pressure overload on diastolic ventricular interdependence in dogs without pericardia, instrumented to measure left ventricular pressure, right ventricular pressure, and 3 left ventricular dimensions. We studied 12 dogs before (control) and nine dogs after 6 weeks of pulmonary artery constriction producing systolic right ventricular pressure gr...
متن کاملEarly improvement in left ventricular diastolic function after relief of chronic right ventricular pressure overload.
Chronic right ventricular pressure overload is associated with left ventricular diastolic dysfunction. Whether or not an abrupt reduction in pulmonary artery pressure in patients with chronic pulmonary hypertension results in early improvement of left ventricular diastolic function is unknown. To assess this, the Doppler indexes of left ventricular diastolic function and echocardiographic measu...
