Penetration of total occlusion
However, the wire could be guided only in the direction of the second diagonal branch due to a severe angulation at the CTO exit site despite successful wire crossing of the CTO lesion Figure 2B. One coronary perforation was found but without cardiac tamponade, no serious complications such as acute myocardial infarction, acute heart failure, death and target vessel rebuilding. Additionally, multifunctional catheters are more difficult to pass than regular microcatheters. Retrograde approach such as retrograde wire crossing and controlled antegrade and retrograde tracking CART if there are available collaterals [ 10 ]. However, the antegrade approach is the basic technique and plays an important role in PCI for CTO lesions. The reason of all the 3 failure cases was due to guiding wire progressing in the false lumen of subintimal and could not adjust back to the true lumen.

Excimer laser recanalization of femoropopliteal lesions and 1-year patency: All Accepts Healthy Volunteers: Moreover, bougie dilatation with the BN allowed balloon crossing and stent deployment, even after failure to pass a 2. Percutaneous coronary intervention PCI using guidewires with normal distal tip equal to 0. Department of Health and Human Services. However, the fundamental question of what type of guidewire is the most appropriate as a first-choice guidewire has not been answered.

Chronic total occlusions — Current techniques and future directions - ScienceDirect
Excimer laser assisted angioplasty for critical limb ischemia: Actual Study Completion Date:. The first choice guidewire to treat CTO lesion was randomly assigned to normal group distal tip size 0. The primary passage must be performed with antegrade approach. The greatest challenge is the passage of the guidewire and a variety of new approaches including a parallel wire technique and a retrograde approach have been reported.
