Distal Target Vessel Quality and Outcomes of Chronic Total Occlusion Percutaneous Coronary Intervention
Authors' conclusion
A poor-quality distal vessel in CTO lesions is associated with higher lesion complexity, higher need for retrograde crossing, lower technical and procedural success, higher incidence of MACE and coronary perforation, and higher radiation dose.
Study context
- Population
