In the United Kingdom, a clinical data set is completed for every patient undergoing coronary intervention and certain structural interventions, and sent to central servers in the National Institute for Cardiovascular Outcomes Research (NICOR) on behalf of the British Cardiovascular Intervention Society (BCIS). These data are linked to the national mortality register. In addition, data are obtained about the structure of healthcare provision using an annual survey. Analyses of these data are provided for different audiences in several formats. Public reports of individual consultant operator activity and risk-adjusted outcomes from percutaneous coronary intervention (PCI) have also been produced annually since 2012. Transcatheter aortic valve implantation (TAVI) has been performed since 2007. Over 2,000 cases were performed in 2015, giving a rate of 30 per million population. Complications to discharge have fallen as case mix has changed and technologies improved. While the mean age has remained about 81 years, the logistic EuroSCORE of patients treated by TAVI has fallen from about 22 in 2010 to 18 in 2015. Tracked 30-day mortality was 3.7% in 2014. Left atrial appendage occlusion and patent foramen ovale (PFO) closure for stroke, and the use of the MitraClip® system (Abbott Vascular, Santa Clara, CA, USA) for mitral regurgitation have been funded through a process called "commissioning through evaluation".
