Article Synopsis
- * The primary outcome was target lesion revascularization (TLR), which occurred in 4.8% of patients, and the secondary outcome was major adverse cardiac and cerebrovascular events (MACCEs), occurring in 14.3%.
- * Key risk factors for TLR included in-stent occlusion, hemodialysis, and diabetes mellitus, while MACCEs were notably associated with hemodialysis and arteriosclerosis obliterans, highlighting the
Background: Despite the effectiveness of the retrograde approach for chronic total occlusion (CTO) lesions, there are no standardized tools to predict the success of retrograde percutaneous coronary intervention (PCI).
Objectives: The aim of this study was to develop a prediction tool to identify CTO lesions that will achieve successful retrograde PCI.
Methods: This study evaluated data from 2,374 patients who underwent primary retrograde CTO-PCI and were enrolled in the Japanese CTO-PCI Expert Registry between January 2016 and December 2022 (NCT01889459).
Article Synopsis
- * Data from 4,088 lesions were analyzed, revealing that PRA was used in 19.2% of cases, with high success rates for both guidewire (93.6%) and technical procedures (91.3%).
- * Key characteristics linked to the use of PRA included previous coronary artery bypass surgery, chronic kidney disease, and specific lesion features like blunt stumps and distal runoff under 1 mm, providing insights for choosing PCI strategies in clinical practice.
(1) Background: The probability of technical success in percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) represents essential information for specifying the priority of PCI for treatment selection in patients with CTO. However, the predictabilities of existing scores based on conventional regression analysis remain modest, leaving room for improvements in model discrimination. Recently, machine learning (ML) techniques have emerged as highly effective methods for prediction and decision-making in various disciplines.

Background: While the technical success of general CTO-PCI has improved, CTO-PCI patients with reduced LVEF remain at high-risk for adverse events.
Methods: The data of 820 patients with LVEF ≤ 35% (Group 1), 1816 patients with LVEF = 35%-50% (Group 2), and 5503 patients with LVEF ≥ 50% (Group 3), registered in the Japanese CTO-PCI Expert Registry from January 2014 to December 2019, were retrospectively analyzed.
