Retrograde Chronic Total Occlusion Percutaneous Coronary Intervention via Saphenous Vein Graft.

Objectives: The aim of this study was to examine the use of saphenous vein grafts (SVGs) for retrograde crossing during chronic total occlusion (CTO) percutaneous coronary intervention (PCI).

Background: The use of SVGs for retrograde crossing during CTO PCI has received limited study.

Methods: A total of 1,615 retrograde CTO PCIs performed between 2012 and 2019 at 25 centers were examined.
