Abstract
During recent years, equipment and techniques for percutaneous coronary intervention
(PCI) of chronic total occlusions (CTO) have improved significantly. The retrograde
approach remains critical to the improved success of CTO PCI. Currently, the reverse
controlled antegrade and retrograde tracking (CART) technique has become the dominant
retrograde wire crossing technique. In this article, we propose a standardised terminology
and classification for this technique divided into three subtypes: a) conventional
reverse CART, usually involving the use of large balloons on the antegrade wire to
achieve re-entry within the CTO segment; b) "directed" reverse CART, which is characterised
by small antegrade balloon size and more active, intentional vessel tracking and penetration
with a controllable retrograde wire, still within the CTO segment; and c) "extended"
reverse CART, in which the intimal/subintimal dissection is extended proximal or distal
to the CTO segment, achieving re-entry outside the CTO segment. The proposed standardised
terminology will facilitate the communication, teaching and adoption of the reverse
CART techniques.
This study sought to perform a weighted meta-analysis of the complication risk during chronic total occlusion (CTO) percutaneous coronary intervention (PCI).
This study sought to develop a novel parsimonious score for predicting technical success of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) performed using the hybrid approach.
This study sought to accurately describe the success rate, risks, and patient-reported benefits of contemporary chronic total occlusion (CTO) percutaneous coronary intervention (PCI).
