Impact of Successful Chronic Total Occlusion Percutaneous Coronary Interventions on Subsequent Clinical Outcomes.
The impact of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) on angina and subsequent incidence of major adverse cardiovascular event (MACE) rate remains controversial. ⋯ Compared with failed CTO-PCI, successful CTO-PCI is associated with better angina improvement and lower incidence of MACE (on univariable analysis) during follow-up.
