Acute, in-Hospital Outcome of Percutaneous Coronary Intervention for In-Stent Chronic Total Occlusion
Highlights
- • Lesion lengths of in-stent CTO were longer than in de-novo CTO alongside with implanted stent lengths and their diameter
- • Examination and fluoroscopy time were longer in patients with in-stent CTO and the amount of contrast medium was higher
- • Overall success rates were comparable between the two group of patients
- • Acute procedural complications were rare and showed no statistically significant difference
Abstract
Background
Percutaneous coronary intervention (PCI) of total chronic total occlusion (CTO) still remains a major challenge in interventional cardiology. Recanalization of in-stent CTO (IS-CTO) is associated with inferior success rates. This present study aims to comparatively evaluate the acute outcome of patients with IS-CTO and de novo CTO.
