Study Details

Study Description

Brief Summary

CrossBoss First is a single-blind randomized controlled trial that will randomize 246 patients undergoing clinically-indicated Chronic Total Occlusion Percutaneous Coronary Intervention, to upfront use of the CrossBoss catheter vs. antegrade guidewire escalation strategy The "CrossBoss First" study has two primary objectives. The primary efficacy objective is to compare the procedure time required to cross the CTO or abort the procedure with a CrossBoss first vs. antegrade wire escalation strategy. The investigators hypothesize that upfront use of the CrossBoss catheter will be associated with shorter procedure time required for CTO crossing compared with an antegrade wire escalation strategy.

The primary safety objective is to compare the frequency of procedural major adverse cardiovascular events (MACE) with upfront use of CrossBoss vs. a guidewire escalation strategy. The investigators hypothesize that upfront use of the CrossBoss catheter will be associated with similar incidence of MACE compared with an antegrade wire escalation strategy.

The secondary endpoints are: (1) technical and procedural success4-6; (2) total procedure time (defined as the interval between administration of local anesthesia for obtaining vascular access and removal of the last catheter); (3) fluoroscopy time to cross the CTO and total fluoroscopy time; (4) total air kerma radiation exposure; (5) total contrast volume; and (6) number of wires, microcatheters, balloons, and stents used.

Outcome Measures

Primary Outcome Measures

    Incidence of procedural major adverse cardiovascular events (MACE, composite death, emergent coronary artery bypass graft surgery, tamponade requiring pericardiocentesis, and stroke)

Secondary Outcome Measures

  1. Procedure time to Cross the CTO [Until end of procedure (usually 2-3 hours after procedure starts)]

  2. Technical and procedural success [Until end of procedure (usually 2-3 hours after procedure starts)]

  3. Total procedure time [Until end of procedure (usually 2-3 hours after procedure starts)]

    Interval between administration of local anesthesia for obtaining vascular access and removal of the last catheter)

  4. Fluoroscopy time to cross CTO and total fluoroscopy time [Until end of procedure (usually 2-3 hours after procedure starts)]

  5. Total air kerma radiation exposure [Until end of procedure (usually 2-3 hours after procedure starts)]

  6. Total contrast volume [Until end of procedure (usually 2-3 hours after procedure starts)]

  7. Number of wires, microcatheters balloons and stents used. [Until end of procedure (usually 2-3 hours after procedure starts)]
