  1. 1. Initial experience with the Glidesheath Slender for Transradial Coronary Angiography and Intervention: a Feasibility Study with Prospective Radial Ultrasound Follow-up. Adel Aminian, MD, Dariouch Dolatabadi, MD, Pascal Lefebvre, MD, Robert Zimmerman, MSc, Philippe Brunner, MD, Georges Michalakis, MD, Jacques Lalmand, MD Centre Hospitalier Universitaire de Charleroi Belgium
  2. 2. Disclosures • I have no relevant financial interests to disclose
  3. 3. Background • Increasing use of TR access worldwide • Radial artery: smaller size and increased tendancy to spasm • 6Fr guide catheters are standard for PCI cases 1 1 Bertrand OF et al. JACC CI 2010; 3:1022–1031.

  5. 5. GLIDESHEATH “SLENDER” CONCEPT GLIDESHEATH “SLENDER” CONCEPT OD 2,63 mm ID 2,22 mm OD 2,45 mm Down Sizing ID 2,22 mm Equivalent Diameter 5Fr Sheath
  6. 6. GLIDESHEATH “SLENDER”: POTENTIAL BENEFITS GLIDESHEATH “SLENDER”: POTENTIAL BENEFITS • 1size down puncture Minimize invasiveness • 1 size up inner lumen Time and cost saving in ad-hoc PCI
  7. 7. GLIDESHEATH “SLENDER”: SPECIFIC CAUTIONS GLIDESHEATH “SLENDER”: SPECIFIC CAUTIONS Terumo t=0.20mm ETFE Terumo t=0.15mm ETFE Terumo t=0.10mm(Trial sample) ETFE Behaviors after the tube was folded at 180° With permission from Terumo
  8. 8. Objectives • To evaluate the feasibility and safety of the Glidesheath Slender in routine transradial (TR) coronary angiography and intervention.
  9. 9. Methods
  10. 10. TR procedures • Verapamil (2mg) and Isosorbide Dinitrate (200400 μg) • IV Heparin 5000 UI – PCI: Adjunctive bolus for ACT 250-300 • 4 or 5 French for diagnostic and 5 or 6 French for PCI
  11. 11. Postprocedural hemostasis • TR band • Strict patent hemostasis protocol • Compression time limited to 2H
  12. 12. Study end-points • Primary endpoint: – Procedural success. • Secondary endpoints: – Vascular access site complications – Symptomatic vascular spasm – Major sheath kinking – Post-procedural radial artery occlusion (RAO).
  13. 13. End-points definitions • Procedural success – Completion of the planned procedure through the initially selected radial access route. • Vascular access site complications – Any documented vascular damage (vessel perforation, arterial dissection, pseudoaneurysm and local hematoma). – Major: hemoglobin loss > 3 g/dl or need for blood transfusion or vascular repair. – Minor: local hematoma > 3 cm diameter without hemoglobin loss > 3 g/dl or need for blood transfusion or vascular repair.
  14. 14. End-points definitions • Symptomatic vascular spasm – Inability to manipulate the guidewire or catheter in a smooth and pain-free manner – Inability to remove the sheath in a similar way at the end of the procedure. – The presence of vascular anatomical variants was also recorded. • Major sheath kinking – Significant deformation of the sheath leading to vascular complication and/or procedural failure. • Post procedural RAO – The absence of a radial pulse assessed clinically together with the absence of flow assessed by Doppler ultrasound examination of the radial artery at 1 month follow-up
  15. 15. 1 full 360° Radio-ulnar loop 2 severe RA tortuosities
  16. 16. High procedural success • 99% PCI through single radial access without sheath upsizing • All comer population – ACS patients – Complex PCI
  17. 17. Low rate of post-procedural RAO • Reduced sheath size • Adequate anticoagulation • First TR procedure • Limited compression time • Strict patent hemostasis protocol
  18. 18. RAO SV. JACC CI 2012
  19. 19. SPECIFIC SETTINGS AT INCREASED RISK OF SHEATH KINKING SPECIFIC SETTINGS AT INCREASED RISK OF SHEATH KINKING • Resistance to sheath insertion – Short skin nick – Push the sheath carefully • During attempts to replace the sheath in case of slippage. – Adhesive dressing
  20. 20. Conclusions • Routine use of the Glidesheath Slender for TR coronary angiography and intervention is safe and feasible with a high rate of procedural success and low rates of vascular complications and RAO. • This new dedicated radial sheath has the potential to allow complex coronary interventions while limiting local trauma to the artery. • Future studies will need to compare the Glidesheath Slender with current 6Fr sheaths with focus on vascular access site complications and RAO.
