Association of Proximal Vessel Tortuosity with Technical Success and Clinical Outcomes: Analysis From the Progress-CTO Registry.

Background: Proximal vessel tortuosity can hinder wiring and equipment delivery during chronic total occlusion (CTO) percutaneous coronary intervention (PCI).

Aims: We sought to examine the association of proximal vessel tortuosity with the short and long-term outcomes of patients undergoing CTO PCI.

Methods: We examined the association of proximal vessel tortuosity with clinical outcomes in patients who underwent CTO PCI at 50 US and non-US centers between 2012 and 2024.

Intravascular Lithotripsy Versus Rotational Atherectomy in Coronary Chronic Total Occlusions: Analysis from the Prospective Global Registry for the Study of Chronic Total Occlusion Intervention Registry.

There are limited comparative data on the use of plaque modification devices during chronic total occlusion (CTO) percutaneous coronary intervention (PCI). We compared intravascular lithotripsy (IVL) with rotational atherectomy (RA) for lesion preparation in patients who underwent CTO PCI across 50 US and non-US centers from 2019 to 2024. Of 15,690 patients who underwent CTO PCI during the study period, 436 (2.

Comparative Analysis of Polymer Versus Non-Polymer Jacketed Wires in Chronic Total Occlusion Percutaneous Coronary Intervention.

There is significant variation in wire utilization patterns for chronic total occlusion (CTO) percutaneous coronary intervention. This study aimed to compare the outcomes of polymer-jacketed wires (PJWs) versus non-PJWs in anterograde procedures. We analyzed clinical and angiographic characteristics, and procedural outcomes of 7,575 anterograde CTO percutaneous coronary interventions that were performed at 47 centers between 2012 and 2023.

Atrial fibrillation and chronic total occlusion percutaneous coronary intervention outcomes: insights from the Progress-CTO registry.

Background: We examined the effect of atrial fibrillation on the outcomes of chronic total occlusion (CTO) percutaneous coronary intervention (PCI).

Methods: We examined the baseline characteristics and procedural outcomes of 9,166 CTO PCIs performed at 39 US and non-US centers between 2012 and 2023.

Results: Atrial fibrillation was present in 1122 (12%) patients.

Outcomes of Chronic Total Occlusion Percutaneous Coronary Interventions in Patients With Previous Coronary Artery Bypass Graft Surgery.

The outcomes of chronic total occlusion (CTO) percutaneous coronary interventions (PCIs) in patients with previous coronary artery bypass graft (CABG) surgery have received limited study. We examined the baseline characteristics and outcomes of CTO PCIs performed at 47 United States and non-United States centers between 2012 and 2023. Of the 12,164 patients who underwent CTO PCI during the study period, 3,475 (29%) had previous CABG.
