Temporal trends of fluoroscopy time and contrast utilization in coronary chronic total occlusion revascularization: insights from a multicenter United States registry.

Background: The impact of operator experience on fluoroscopy time and contrast utilization during percutaneous coronary intervention (PCI) of coronary chronic total occlusions (CTOs) has received limited study.

Methods: We evaluated temporal trends in fluoroscopy time and contrast utilization among 1,363 consecutive CTO PCIs performed at three US institutions between January 2006 and November 2011.

Results: Mean age was 65 ± 11 years, 85% of patients were men, 40% had diabetes, 37% had prior coronary artery bypass graft surgery, and 42% had prior PCI.

Procedural outcomes of revascularization of chronic total occlusion of native coronary arteries (from a multicenter United States registry).

Percutaneous coronary intervention (PCI) of chronic total occlusions (CTOs) is a rapidly evolving area of interventional cardiology. We sought to examine the immediate procedural and in-hospital clinical outcomes of native coronary artery CTO PCI from a multicenter United States (US) registry. We retrospectively examined the procedural outcomes of 1,361 consecutive native coronary artery CTO PCIs performed at 3 US institutions from January 2006 to November 2011.

Impact of prior coronary artery bypass graft surgery on chronic total occlusion revascularisation: insights from a multicentre US registry.

Objective: To investigate the impact of prior coronary artery bypass graft (CABG) surgery on the outcomes of percutaneous coronary intervention (PCI) for chronic total occlusions (CTO).

Design: Observational retrospective study.

Setting: Three tertiary hospitals in the USA.

Retrograde coronary chronic total occlusion revascularization: procedural and in-hospital outcomes from a multicenter registry in the United States.

Objectives: This study sought to examine the contemporary outcomes of retrograde chronic total occlusion (CTO) interventions among 3 experienced U.S. centers.
