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 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...
متن کاملClinical 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 کاملApplication of centrifugal pump in right ventricular failure due to pulmonary artery hypertension. (A case report)
Background: It has not been yet developed a ost suitable method to treat right ventricular failure due to pulmonar artery hypertention resulted from ventricular arrhythia. Though some case reports about patients ready to heart transplant using left assist device or biventral assist device as bridge have been published in Journals, but nocase concerning application of centrifugal pump for treatm...
متن کاملLeft Ventricular Diastolic Dysfunction in Pediatric Pulmonary Hypertension.
Pulmonary hypertensive vascular disease (PHVD) is characterized by progressive narrowing of pulmonary arterioles, abnormally high pulmonary vascular resistance (PVR), right ventricular (RV) dysfunction, left ventricular (LV) compression, and death in ≈25% to 60% of patients with pulmonary arterial hypertension (PAH) 5 years after diagnosis. Meanwhile, consensus statements have been developed in...
