In-hospital outcome of re-attempted percutaneous coronary interventions for chronic total occlusion
open access
Abstract
Background: With the advent of novel recanalization techniques and emerging devices, percutaneous coronary intervention (PCI) has become a promising leading treatment option for patients with chronic total occlusions (CTO). The present study aims to evaluate the acute outcomes of PCI in previously failed re-attempted vs. first-attempted CTO-lesions. Methods: Between 2012 and 2019, 619 patients were included and treated with PCI of at least one CTO. 253 patients were re-attempted lesions, while 366 were initially attempted lesions. Results: Re-attempted lesions were more complex, including higher Japanese-CTO (J-CTO) score and the need for a retrograde approach. The procedure time and fluoroscopy time were longer in this group. Nevertheless, overall success rates were comparable between both groups of patients. In-hospital events were rare and without significant differences. Conclusions: Re-attempted CTO lesions are more complex than first-attempt lesions and are associated with longer procedural times. However, they can be safely intervened by experienced operators with a similar success rate.
