4D Flow Assessment of Vorticity in Right Ventricular Diastolic Dysfunction
Diastolic dysfunction, a leading cause of heart failure in the US, is a complex pathology which manifests morphological and hemodynamic changes in the heart and circulatory system. Recent advances in time-resolved phase-contrast cardiac magnetic resonance imaging (4D Flow) have allowed for characterization of blood flow in the right ventricle (RV) and right atrium (RA), including calculation of...
متن کاملVorticity for the assessment of right ventricular diastolic dysfunction using 4D flow CMR
Background 4D flow CMR analysis of right ventricular (RV) diastolic inflow has demonstrated vortical formations at tips of the tricuspid valve during the deceleration phase of early filling (E wave) (Figure 1). Vorticity can measure the rotation of these vortices and may represent a novel way to assess RV diastolic function. We aimed to determine if right heart vorticity identified right ventri...
متن کاملCardiac imaging in pulmonary embolism: assessment of right ventricular dysfunction by tissue Doppler.
O tromboembolismo pulmonar (TEP) é uma entidade relativamente frequente no contexto de urgência hospitalar, com uma elevada taxa de mortalidade e morbilidade quando não tratado precocemente, continuando a representar um desafio diagnóstico na prática clínica diária, sendo a sua apresentação clínica nem sempre esclarecedora, especialmente no contexto agudo1. A mortalidade de doentes por TEP nos ...

متن کاملEffect of secretin on portal venous flow.
In this study we evaluated the effect of two different doses of secretin on portal haemodynamics (by pulsed Doppler associated with real time ultrasound) in 24 healthy humans. In 12 subjects (group A) we administered an intravenous dose of 75 clinical units of secretin and in the remaining 12 (group B) a dose of 20 CU. In all subjects the following parameters were studied before, during, and fo...
