BACKGROUND The aims of this study were to validate MRI-derived right ventricular (RV) pressure-volume loops for assessment of RV myocardial contractility and then to apply this technique in patients with chronic RV pressure overload for assessment of myocardial contractility, ventricular pump function, and VA coupling. METHODS AND RESULTS Flow-directed catheters were guided under MR fluorosco...

The Office of Nursing Services of the Department of Veterans Affairs (VA) piloted implementation of the clinical nurse leader (CNL) into the care delivery model and established a strategic goal in 2011 to implement the CNL role across the VA health care system. The VA Office of Nursing Services CNL Implementation and Evaluation (CNL I&E) Service was created as one mechanism to facilitate that g...

Background: Knowledge of variations in the origin of vertebral artery (VA) is indispensable to vascular surgeons. Aberrant origin of vertebral artery on either side is an uncommon finding. There are unilateral and bilateral variability in VA origin. Case presentation: We present a case of vertebral artery dissection who was found to have bilateral VAs aberrant origin. The right VA took origin ...
