Patients undergoing transcatheter aortic valve replacement (TAVR) are at a higher risk of recurrent healthcare resource utilization due to multiple comorbidities, frailty, and advanced age. The 30-day all-cause readmission rate has been reported at 15-20%. We have devised a simple tool to identify patients at higher risk of 30-day readmission using the Nationwide Readmissions Databases (from January 2013 to September 2015). This simple and easy-to-use risk prediction tool may help identify TAVR patients at increased risk of 30-day readmission, and aid in appropriate transition of care upon discharge and post-discharge follow-up.

DeviceAID is an educational application with many categories of devices used in both diagnostic Cath as well as interventional cardiology. With hundreds of devices to keep in your head, having a tool to get to the key few numbers can be invaluable. A basics section introduces devices, and the library section allows for the searching and filtering of devices based on some key characteristics. Current sections include Catheters, stents, balloons, atherectomy devices, access, closure, and more. Devices can be added to your personal favorites list for easy access later. For those who want to refine their knowledge of devices, quizzes with correct answer explanations are available.
