Objective Delirium after cardiac surgery is associated with persistent cognitive deficits and increased mortality. The authors’ objective was to determine the incidence of and risk factors for delirium in a mixed cohort of patients undergoing on-pump and off-pump cardiac surgery and transcatheter aortic valve implantations (TAVI) in a Canadian quaternary care center. This study followed a pilot from the same center on patients treated in 2007. Design A retrospective cohort study. Setting A quate...

Aim Mobility issues in the early postoperative period result in poor functional outcomes and diminished quality of life for patients of advanced age. We determined the incidence of and risk factors for mobility issues in the early postoperative period in patients receiving open heart cardiac surgery. Methods A retrospective chart review was carried out on 396 patients receiving open heart coronary artery bypass grafts (CABG), valve replacements and combination CABG-valve replacements in a tertia...

Purpose Transcatheter aortic valve implantation (TAVI) techniques show favourable survival outcomes in high-risk patients, but the incidence of postoperative delirium is unknown. We conducted a historical cohort study to compare postoperative delirium in retrograde transfemoral (TF) versus anterograde transapical (TA) TAVI procedures. We also sought to identify independent predictors of delirium following TAVI.

Background Acute kidney injury (AKI) is defined as oliguria or rise in serum creatinine but oliguria alone as a diagnostic criterion may over-diagnose AKI.

OBJECTIVES The purpose of this study was to determine the origin of the pulmonary venous systolic flow pulse using wave-intensity analysis to separate forward- and backward-going waves. BACKGROUND The mechanism of the pulmonary venous systolic flow pulse is unclear and could be a “suction effect” due to a fall in atrial pressure (backward-going wave) or a “pushing effect” due to forward-propagation of right ventricular (RV) pressure (forward-going wave). METHODS In eight patients during coronary...
