The STS/ACC TAVR In-Hospital Mortality Risk App informs physicians of the estimated risk of in-hospital mortality for patients considering transcatheter aortic valve replacement as a treatment option. Physicians can compare individual patient risk to the national average based on data from the STS/ACC TVT Registry^TM. The app facilitates consistent risk assessment and communication between a physician and patient about TAVR. (Long Version Boilerplate).

The STS/ACC TAVR In-Hospital Mortality Risk App is intended to be used by physicians at the point-of-care to evaluate a patient’s potential risk of death while in the acute care setting from the TAVR procedure.

Yes.

The ACC and STS collaborated on the development of the App as part of its relationship on the STS/ACC TVT Registry^TM. This registry is a joint effort between the ACC and the STS that monitors outcomes related to transcatheter valve replacement and repair procedures.

The STS/ACC TAVR In-Hospital Mortality Risk App is intended for use by physicians, specifically cardiologists, interventionalists, and cardiac surgeons. Secondary users may include valve coordinators and registry site managers.

All of the content in the app was based on a risk model developed using the data from the STS/ACC TVT Registry^TM. As of May 2015, registry data show that the national average for in-hospital mortality from TAVR is 4%.

The STS/ACC TAVR In-Hospital Mortality Risk App is based on a risk model developed using the data the STS/ACC TVT Registry^TM which is offered as part of the ACC National Cardiovascular Data Registry (NCDR).The App is also part of the ACC’s growing Clinical Mobile App Collection, consisting of tools for use “on the go” to help optimize patient care. More information about the ACC Clinical App Collection can be found on ACC.org.

The STS/ACC TAVR In-Hospital Mortality Risk App was developed at the ACC in collaboration with STS using the STS/ACC TVT Registry risk-adjusted mortality model. Development of the App was overseen by a group of clinical leaders and experts representing the target audience. Technical experts designed and built the App. Several rounds of user testing were conducted by physicians, nurse practitioners, and others with sample patients.

Users enter some patient demographic data such as age, sex and race/ethnicity in the STS/ACC TAVR In-Hospital Mortality Risk App. This information can be emailed anonymously from the App during the course of an app session to the user’s personal email. No information is stored in the App. User behavior (e.g., number downloads, number of times a day app is used, which buttons in the app are clicked most often) are gathered anonymously through Google Analytics.

The App is available for free online at ACC.org and for download in the iTunes or Google Play App stores. Search “ACC STS TAVR Risk”.

Contact the ACC at 1-800-253-4636 or Resource@ACC.org.

If the national average changes the app will reflect that on the “predicted risk” screen.

The national average is calculated quarterly.

The risk model manuscript is expected to be published by May 2015 in JAMA Cardiology.

The TAVR In-Hospital Mortality Risk Model was developed by the STS/ACC TVT Registry Risk Model Work Group, a team assembled of ACC and STS members, as well as statisticians from Duke Clinical Research Institute.
