Impella 5.5 Use in the Setting of Severe Aortic Insufficiency: A Relative Contraindication

Annals of Thoracic Surgery Short Reports
Moderate or severe aortic insufficiency is a contraindication to transvalvular Impella left ventricular assist device (Abiomed) use out of concern for worsening valvular insufficiency and recirculation. This report describes the case of a 75-year-old man

In vitro characterization of hemodynamics in bicuspid aortic valves: The impact of valve and ascending aortic morphologies

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose This study investigated the effect of bicuspid aortic valve (BAV) morphology and ascending aortic curvature (AAAc) bending angles on aortic hemodynamics, focusing on transvalvular jets and secondary helical flows that contribute to systolic hemodynamic stress linked to aortic complications.

Coronary Artery Blood Flow Imaging Using 3D Flow MRI

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose In this work, a 3D phase contrast (PC) technique is presented, which enables flow velocity measurements in three spatial directions, simultaneously covering the proximal left (LCA) and right (RCA) coronary arteries and yielding both morphological and flow information.

Comparison between the NUTRIC score and modified NUTRIC score to predict hospital mortality in patients undergoing cardiac surgery: A retrospective study

Nutrition in Clinical Practice, EarlyView.
Abstract Background Nutrition status evaluation is essential for patients undergoing cardiac surgery. The Nutrition Risk in the Critically Ill (NUTRIC) and modified NUTRIC (mNUTRIC) scores are nutrition risk assessment tools specifically for patients in the intensive care unit (ICU).
