Chronic Total Coronary Artery Occlusion Recanalisation with Percutaneous Coronary Intervention — Single Centre 10-Year Experience
2018
Abstract Coronary artery chronic total occlusions (CTO) are common — approximately one-third of patients with significant coronary artery disease on angiography have at least 1 CTO. Invasive treatment of these lesions still remain a major challenge for interventional cardiology due to their complexity. Historically, success rates have improved to about 60–70% by using only the traditional antegrade approach. The results have dramatically improved during the last decade after more widespread application of new retrograde techniques. The aim of our study was to review and analyse single hospital experience in CTO invasive treatment and to evaluate the long-term results. A total of 519 patient…
Channel Tracking Guidewire and Technique for Retrograde Approach
2020
Evaluation of the collateral circulation is critical for determining the feasibility of the retrograde approach. When assessing collateral channels it is of paramount importance to take time and review the previous angiogram carefully, for multiple potential collateral pathways, as the predominant collateral may change over time prior to the procedure. Careful review of collaterals prior to the procedure can reduce contrast and radiation dose as well as the duration of the procedure.Retrograde access to the distal vessel can be achieved via septal collaterals, epicardial collaterals (atrial channel), or (patent or occluded) coronary bypass grafts. Generally septals are used more often 65–70…
Trans-popliteal hybrid retrograde technique for revascularization of chronic total occlusions of the superficial femoral artery.
2020
Objectives We present the technical description and preliminary results of a hybrid approach for the treatment of chronic total occlusions of superficial femoral artery in the setting of critical limb-threatening ischemia (CLTI). Methods A retrospective analysis of selected case series was performed. A trans-popliteal hybrid technique was carried out in seven limbs (six patients). Open exposure of above-the-knee popliteal artery was performed over its maximum calcification zone. After retrograde recanalization and graft-stenting of the entire superficial femoral artery, endarterectomy of the popliteal artery was performed for debulking and widening of the distal landing zone of the endopros…
Retrograde recanalization of an in-stent ostial chronically occluded right coronary artery
2010
We describe a case of a chronic proximal in-stent CTO extending up to the ostium of a right coronary artery where successful achievement of guidewire passage through the CTO was performed with a retrograde approach. Guidewire trapping into the right guiding catheter was performed thereafter and procedure was completed by retrograde balloon crossing and antegrade stenting. © 2009 Elsevier Ireland Ltd.
