However, there is a lack of data on how hospital volumes affect these outcomes.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We performed a cross sectional study based on Healthcare Cost and Utilization Project's Nationwide Inpatient Sample database of 2012 and identified subjects using the ICD\u20109\u2010CM procedure code of 35.97, which was introduced in October 2010 for percutaneous mitral valve repair if present in the primary or secondary procedure field. Hospital volumes were divided into tertiles. The primary outcome was a composite of in\u2010hospital mortality and peri\u2010procedural complications. Length of stay and hospitalization cost were also assessed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 95 (weighted n\u2009=\u2009475) TMVR procedures were identified. The mean age of the overall cohort was 70 years; 43.2% were female and 63.2% had a significant baseline burden of co\u2010morbidities. The composite of in\u2010hospital mortality and peri\u2010procedural complications decreased with increasing TMVR hospital volume: 48.7% in the first tertile, 17.4% in the second tertile, and 9.1% in the third tertile.
