Insights
Retrograde wiring offers a rescue strategy for coronary artery perforation during chronic total occlusion (CTO) interventions. This technique successfully sealed a perforation and enabled antegrade stenting in a bypass graft patient.
Area of Science:
- Cardiovascular Interventions
- Interventional Cardiology
- Coronary Artery Disease
Background:
- Percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) presents significant technical challenges.
- Retrograde wiring is an advanced technique to improve PCI success rates in CTO cases.
Observation:
- Coronary perforation occurred during antegrade wiring of a CTO lesion in a patient with prior coronary artery bypass grafting (CABG).
- The perforation was successfully managed using a retrograde wiring approach.
Findings:
- Retrograde wiring facilitated sealing of the coronary perforation.
- Antegrade stenting was successfully completed after the perforation was sealed via the retrograde approach.
- This case demonstrates the utility of retrograde wiring as a rescue strategy in complex CTO interventions.
Implications:
- The retrograde wire technique can be a valuable rescue option for coronary perforation during CTO PCI.
- This approach is particularly relevant in patients with suitable retrograde conduit vessels, such as patent bypass grafts.
- Successful management of perforation can improve outcomes in challenging CTO interventions.
Abstract:
Percutaneous coronary intervention of chronic total occlusion (CTO) is one of the greatest challenges in coronary interventions. Retrograde wiring is suggested as a solution to improve the success rate of intervention for CTO. We experienced the coronary perforation during antegrade wiring at the CTO lesion and sealed it using retrograde wiring and antegrade stenting in a patient who underwent coronary arterial bypass grafting. We found that, in selected cases, the retrograde wire technique may provide a valuable rescue option for perforated CTO in a patient having a retrogradely accessible conduit vessel.
