Clinical and angiographic outcomes of crossing techniques for coronary chronic total occlusions: the ISAR-CTO registry.

ABSTRACT:

Background

Clinical and angiographic outcomes following recanalisation of coronary chronic total occlusions (CTO) through contemporary dissection and re-entry techniques (DART) as opposed to intraplaque techniques remain controversial.

Aims

The aim of this study was to compare clinical and angiographic outcomes following subintimal and intraplaque CTO recanalisation.

Methods

A total of 454 consecutive patients undergoing successful CTO recanalisation (473 vessels) were included. Intraplaque techniques were used in 403 (85.2%) and DART in 70 (14.8%) vessels. Surveillance angiography was scheduled at 6-9 months and clinical follow-up was performed up to 12 months.

Results

There were no significant differences in terms of the cumulative incidence of MACE (p=0.908)
