Fallon and colleagues evaluated patient-prosthesis mismatch (PPM) following isolated aortic valve replacement reported in the STS Adult Cardiac Surgery Database. They found that both moderate and severe PPM were associated with worse outcomes compared to no PPM over the 10-year study period.

Research published recently in The Annals of Thoracic Surgery suggests a new approach for evaluating a patient’s risk for acute kidney injury before they undergo cardiac surgery.

Chan and colleagues describe a stepwise approach to reducing the time to extubation after cardiac surgery, driven primarily by bedside providers as opposed to a conventional physician-directed approach.

A brief, readable, sensibly balanced, and well-referenced editorial on the occasion of the retrospective Austrian paper on venoarterial extracorporeal membrane oxygenation (ECMO).

Sample size calculations are a necessary prerequisite in the design of clinical studies. Most often, they are encountered in randomized controlled trials. Hickey and colleagues describe the reasoning behind determinations of sample size and illustrate some basic calculations.

A young patient with a failed bicuspid valve repair and remodeling aortic root replacement underwent a successful re-repair using bicuspid ring annuloplasty and leaflet plication.

Controversial and revisited topic of dual-antiplatelet therapy (DAPT) (aspirin and clopidogrel) versus low dose warfarin after On-X mechanical aortic valve replacement. There were two arms to the study: low and high risk for thromboembolism. The low-risk arm was terminated secondary to higher thromboembolic events in the DAPT group. For the high-r
