• Use of transcatheter endovascular stenting has been increasing in the treatment of coarctation of aorta (CoA). The present study was undertaken on adults with CoA who underwent stent placement from 2000 to 2011 to analyze the relation of hospital volumes to the outcomes of stenting in adults with CoA. It was a retrospective study based on Healthcare Cost and Utilization Project's Nationwide Inpatient Sample (NIS) database from 2000 to 2011 and identified subjects using the International Classification of Diseases, Ninth Revision, Clinical Modification procedure code of 747.10 (CoA). Annual hospital volume was calculated using unique hospital identifiers. Weights provided by the Nationwide Inpatient Sample were used to generate national estimates. A total of 105 (weighted 521) subjects were identified with International Classification of Diseases, Ninth Revision , code of 39.90 (Endovascular stent). Hospital volumes were divided into tertiles. We compared the highest tertile (≥3 procedures annually) with other tertiles (<3 procedure annually). The composite outcomes of the analysis were procedure-related complications, length of stay (LOS), and cost in relation to the hospital volume. No inhospital death was reported in either group. Hospitals with ≥3 procedures annually had significantly lower incidence of complications (9.5% vs 23.0%) compared to the hospitals with <3 procedures annually (p-value 0.002). Similar results were obtained after multivariate regression analysis in relation to hospital volume. Shorter LOS and lower cost were observed with annual hospital volume of ≥3 procedures. In conclusion, stenting adults for CoA is remarkably safe, and the outcomes of the procedure have improved in centers with annual hospital volume of ≥3 procedures. There is also decreasing trend of procedure-related complications, shorter LOS, and lower costs compared to centers with annual volume <3 procedures.
