Same day discharge after large bore vascular access in percutaneous coronary intervention of chronic total coronary occlusions

Abstract Background Same day discharge (SDD) in patients undergoing percutaneous coronary intervention (PCI) of a chronic total coronary occlusion (CTO) appears feasible, safe, and carries economic advantage. However, SDD may be hampered by the application of large bore dual arterial access, due to its association with vascular complications. Nevertheless, increasing French size augments therapeutic options and is therefore considered fundamental in complex CTO PCI. Purpose The present study investigated the feasibility of SDD in patients undergoing CTO PCI with large bore dual arterial access. Methods Between 2013 and 2018, a total of 683 patients were prospectively enrolled in a single-center CTO registry and underwent single-vessel CTO PCI. Large bore arterial access was defined as the application of 7 and/or 8 French sheaths in at least one access site. Technical success was defined as Thrombolysis in Myocardial Infarction flow grade 3 and residual stenosis
