P1405 3D echocardiographic assessment of right ventriculo-arterial coupling in mitral valve prolapse
BACKGROUND Right ventricular (RV) function is a major determinant of outcome in pulmonary arterial hypertension (PAH). However, uncertainty persists about the optimal method of evaluation. METHODS We measured RV end-systolic and end-diastolic volumes (ESV and EDV) using cardiac magnetic resonance imaging and RV pressures during right heart catheterization in 140 incident PAH patients and 22 c...
During galloping, many animals display 1:1 coupling of breaths and strides. Locomotor respiratory coupling (LRC) may limit respiratory evaporative heat loss (REHL) by constraining respiratory frequency (f). Five sheep were exercised twice each, according to a five-step protocol: 5 min at the walk, 5 min at the trot (trot1), 10 min at the gallop, 5 min at the trot (trot2), and 5 min at the walk....
Numerical simulation of the response healthy and pathological arteries to cardiovascular agents can provide valuable information physician in treatment diseases such as hypertension, atherosclerosis, Marfan syndrome. Here, we a first step towards computational framework model effects antihypertensive on mechanical arterial walls. A material is developed by extending an existing formulation for ...
