B-19 | Comparison of Cost of Hospitalization between Single-Vessel Chronic Total Occlusion and Non Chronic Total Occlusion Percutaneous Coronary Intervention

Abstract

Successful percutaneous coronary intervention (PCI) of chronic total occlusion (CTO) leads to improvement in anginal symptoms and ventricular function. As CTO PCI are technically challenging, associated with more complications and require additional equipment, we hypothesize that they are associated with a higher cost of hospitalization as compared to non-CTO PCI. In this retrospective study using the National Inpatient Sample (NIS) we compare the cost of hospitalization associated with elective single vessel (SV) CTO PCI to SV non-CTO PCI.
