Trial Outcomes & Findings for Chronic Total Occlusion Percutaneous Coronary Intervention Study (NCT NCT03988166)

NCT ID: NCT03988166

Last Updated: 2022-09-28

Results Overview

Defined as angiographic visualization of any guidewire in a position either distal or proximal to the occlusion depending on the route of access and the absence of in-hospital major adverse cardiac events (MACE). • MACE defined as any serious adverse experience that includes cardiac death, target lesion revascularization, or post-procedural myocardial infarction (MI) (Q-wave or non-Q-wave, with creatine kinase (CK) with Muscle (M)-Brain (B) subunits \> 3 ULN).

Chronic Total Occlusion Percutaneous Coronary Intervention
CTO percutaneous coronary intervention (PCI) in which at least one Teleflex guidewire and at least one Turnpike catheter are used. Chronic Total Occlusion Revascularization: Teleflex's series of study guidewires and catheters will be used to facilitate the safe and effective crossing of de novo CTOs and placement of conventional guidewires beyond the lesion via either a true lumen or subintimal pathway.
