Other risk models, such as one estimating individual patient risk may follow. The initial model compares in-hospital mortality across participating centers, potentially identifying outliers as more data accumulate in the Registry. All 13,218 Cases are Commercial TAVR 272 Sites Enrolled in TVT Registry 258 Sites Entering Data 5 Sites > 200 Cases; 24 Sites > 100 Cases Does Not Include All TAVR Cases in US Over 10K Cases from IDE Trials Some Commercial TAVR Cases Before NCD, VA Cases 3
Distribution of Sites by Annual Volume Number of Sites Note: Investigative case volume at sites isnot counted Annualized Volume Groups Source: STS/ACC TVT Registry Database 2-6-14 Sites Participating in TVT Registry (Currently TAVR) No TAVR sites in Alaska and Wyoming (currently patients served by Seattle and Colorado sites) 1. As of last week 272 TAVR sites fully enrolled. Additional sites being trained by Edwards and Medtronic will be added. 2. Approximately 35 sites who have started commercial MitraClip use are already TAVR-TVT sites. STS/ACC TVT Registry Data Quality Program 4
Data Quality Program Pre data collection Data submission Post data submission Software Training Clinical support Data quality reports Adjudication Audit Outlier program Publications Data Quality Program Post Submission Adjudication Verifies and provides additional information for key events (stroke, TIA and repeat intervention, plus CHF admission for MitraClip) National audit program (starts in 2014) Evaluates accuracy and reliability Assesses proper and complete reporting of cases Voluntary and self audits Data Outlier Program Provides outlier alerts to Registry participants Adjudication Process: Additional Data and Physician Review at DCRI 5

David R. Holmes, J. Matthew Brennan, John Rumsfeld, Dadi (David) Dai, Fred Edwards, John Carroll, David Shahian, Frederick Grover, E. Murat Tuzcu, Eric Peterson, Ralph Brindis, Michael Mack. CMS has successfully linked the STS/ACC TVT Registry to inpatient Medicare claims using direct patient identifiers with a roughly 97% record linkage rate across more than 7,500 TAVR cases from Nov 2011 through October 2013.

Research and Publications Initial Phase: Steering Committee Members to Provide the First Wave of Strategic Presentations and Publications Current Phase: January 2014 the R & P Committee accepted outside research proposals for using the TVT Registry data 80 proposals were received! R & P committee now performing reviews and establishing priorities Post-Approval Studies, IDE s, and Uses of Registry Data for Expansion of Indications STS-ACC actively involved with discussions with FDA How are data collected in observational registries? How can data be used to support post-approval studies and investigative device exemptions ( IDE s )? What are the applicable informed consent requirements? How to best utilize the vast amount of patient-level data while assuring the safety and protection of human subjects and imposing the least burden on the sponsors and participating hospitals? Outcomes from TAVR and Surgical AVR Is Consumer Level Reporting Coming? 11
Outcomes of TAVR at Different Sites How and when can the TVT registry provide an analysis of outcomes per site that is credible and actionable? 1. To assist patient, families, and clinicians in site selection 2. To provide CMS, professional societies, and medical device companies on the success of the current site qualification standards used in the NCD 3. To provide guidance on whether the number of TAVR sites should be further expanded with less stringent qualifications 4. To determine learning curve effects, the volume-outcome relationship in TAVR, and the determination of best practices to improve outcomes 5. To start a dialogue on how sites with poor outcomes should be approached. Step #1: Outcomes Must Be Adjusted to The Characteristics of the Patients Being Treated Is the observed outcome equal, less, or more than predicted for a site s patients? The risk-model development group: Fred Edwards and others The first TVTR risk model should be available in May 2014. Other Factors Determining Outcomes TAVR technology is changing and the TVT Registry should show substantial changes (reductions) of many complications as new and better valves/delivery systems are approved. The learning curve continues to operate for the whole community and individual sites. Identification of patients who may have underlying characteristics predicting a poor outcome may help guide centers in the key issue of patient selection 12
Other Lessons Learned in Judging Sites Statistical assessment of sites with low volumes is problematic. Geographical distribution of sites is key for patient access Assuming 1. Patients, Families, and Clinicians Have Access to TAVR and savr 2. Sites Have Outcomes That Are at Least as Good as Expected How Can The TVT Registry Be Used to Help Patients, Families, and Clinicians in Key Patient-Centric Decisions? Optimizing Health Outcomes in Patients with Symptomatic Aortic Valve Disease. PICORI Grant Awarded Late 2013 Matthew Brennan, MD Principle Investigator DCRI 13
Research Goal: Help patients make informed treatment decisionsthat incorporate their preferences and outcomes of interest 1. Creation and assessment of statistical prediction models accurate and valid patient-level predictions of outcomes for patients with severe aortic stenosis treated with SAVR vs. TAVR. 2. Creation of decision assistance tools suitable for use by patients Surgical candidates A second tool for patients who have surgically inoperable disease. 3. Dissemination of these tools into clinical practice using a webbased platform coupled with a pilot evaluation of their effectiveness Questions? 14
