The Society of Thoracic Surgeons (STS)/ACC Transcatheter Valve Therapy (TVT) Registry has revealed a number of important trends and improvements in the patient outcomes and clinical care of transcatheter aortic valve replacement (TAVR) patients, according to the 2016 Annual Report of the STS/ACC TVT Registry published Dec. 9 in the Journal of the American College of Cardiology. This annual report focuses on patient characteristics, trends and outcomes of transcatheter aortic and mitral valve catheter-based valve procedures in the U.S. from late 2011 through December 2015. The TVT Registry has three modules: TAVR, transcatheter mitral leaflet clip, and transcatheter mitral valve-in-valve therapy/transcatheter mitral valve-in-ring therapy. The registry’s TAVR module shows that actual TAVR in-hospital, 30-day, and one-year mortality significantly decreased over time. Of note, one-year mortality decreased from 25.8 percent in 2012 to 21.6 percent in 2014, and the report found modest but significant decreases in acute kidney injury and major bleeding over time.
