TL;DR: New STS risk models have been developed for CABG mortality and eight other endpoints and overall model performance is excellent, with acceptable calibration in the overall population and in numerous subgroups.
Journal ArticleDOI
The Society of Thoracic Surgeons 2008 cardiac surgery risk models: part 2--isolated valve surgery.

TL;DR: New valve surgery models using contemporary data that include both valve repair as well as replacement are developed, expanding upon existing valve models, and include several nonfatal complications in addition to mortality.

TL;DR: This research presents a novel and scalable approach called “SmartCardiothoracicSurgery,” which aims to provide real-time information about the plaque-free reperfusion rate of deep vein thrombosis in the arteries of the heart.

TL;DR: In this article, the authors compared biological versus mechanical aortic valve prosthesis in older individuals and found that those receiving a mechanical valve had a similar adjusted risk for death (hazard ratio, 1.04; 95% confidence interval 1.01-1.07), higher risk for other adverse outcomes, including death, stroke, and bleeding.
