Left ventricular vorticity is marker of ventricular interdependency in pulmonary arterial hypertension
Background Chronic right ventricular (RV) pressure and volume overload in pulmonary arterial hypertension (PAH) results in leftward shift of the interventricular septum and impaired left ventricular (LV) diastolic function. However, the impact of PAH-mediated interdependency on LV fluid mechanics and fluid/structure interactions in LV diastolic dysfunction is incompletely understood. 4D flow CM...
متن کاملLeft ventricular dysfunction in patients with suspected pulmonary arterial hypertension*
OBJECTIVE To evaluate the role of right heart catheterization in the diagnosis of pulmonary arterial hypertension (PAH). METHODS We evaluated clinical, functional, and hemodynamic data from all patients who underwent right heart catheterization because of diagnostic suspicion of PAH--in the absence of severe left ventricular dysfunction (LVD), significant changes in pulmonary function tests, ...
متن کاملLeft-Ventricular Energetics in Pulmonary Arterial Hypertension-Induced Right-Ventricular Hypertrophic Failure
Pulmonary arterial hypertension (PAH) alters the geometries of both ventricles of the heart. While the right ventricle (RV) hypertrophies, the left ventricle (LV) atrophies. Multiple lines of clinical and experimental evidence lead us to hypothesize that the impaired stroke volume and systolic pressure of the LV are a direct consequence of the effect of pressure overload in the RV, and that atr...
متن کاملwhich type of right ventricular pressure overload is worse? an echocardiographic comparison between pulmonary stenosis and pulmonary arterial hypertension
conclusions it seems that severe pah aggravates the rv function more severely. results significant tricuspid regurgitation was more prevalent in the pah group than in the ps group (61% vs. 18.5%; p < 0.001). the abnormalities in the rv myocardial performance index, rv areas, and rv fractional area change were significantly more robust in the pah group (all ps < 0.05) despite the higher net rv s...
متن کاملVorticity is a marker of right ventricular diastolic dysfunction.
Right ventricular diastolic dysfunction (RVDD) is an important prognostic indicator in pulmonary arterial hypertension (PAH). RV vortex rings have been observed in healthy subjects, but their significance in RVDD is unknown. Vorticity, the local spinning motion of an element of fluid, may be a sensitive measure of RV vortex dynamics. Using four-dimensional (4D) flow cardiac magnetic resonance i...
