First prospective multicentre experience with left distal transradial approach for coronary chronic total occlusion interventions using a 7 Fr Glidesheath Slender.

AIMS
to assess the feasibility and safety of the left distal transradial artery (LDTRA) approach using a 7 Fr Glidesheath Slender for chronic total occlusion (CTO) percutaneous coronary interventions (PCIs).


METHODS AND RESULTS
From March to May 2018 a total of 41 consecutive CTO PCIs were performed through LDTRA access using a 7 Fr Glidesheath Slender. Technical and procedural success, defined as achievement of technical success using the initially selected LDTRA access with no in-hospital mayor adverse cardiovascular events (MACE), were respectively 90,3% and 78%. Failure in achieving LDTRA access was 17,1%. There were no vascular access-site complications such as no post-procedural LDRAOs. Doppler ultrasound imaging of the left distal radial artery at 1 month was available in 67,6% of patients with only one case (4.3%) of LDRAO in a female patient.


CONCLUSIONS
LDTRA approach using a 7 Fr Glidesheath Slender for CTO PCIs is feasible and associated with high rate of procedural success and low rate of vascular access-site complications.
