Determinants of operator and patient radiation exposure during cardiac catheterization: Insights from the RadiCure (RADIation reduction during cardiac catheterization using real-timE monitoring) trial.
Catheter Cardiovasc Interv
December 2016
Background: In the RadiCure study 505 catheterization procedures were 1:1 randomized to use or no use of real-time radiation monitoring. Use of the Bleeper Sv monitor resulted in a significant reduction in operator radiation exposure.
Methods: We examined the association between several baseline and procedural parameters with operator and patient radiation exposure using univariable and multivariable analysis in the 505 patients that were enrolled in RadiCure.
Background: Daily radiation exposure over many years can adversely impact the health of medical professionals.
Methods: Operator radiation exposure was recorded for 124 percutaneous coronary interventions (PCIs) performed at our institution between August 2011 and May 2013: 69 were chronic total occlusion (CTO)-PCIs and 55 were non-CTO PCIs. A disposable radiation protection sterile drape (Radpad; Worldwide Innovations & Technologies, Inc) was used in all CTO-PCI cases vs none of the non-CTO PCI cases.
Background: The BridgePoint system consists of the CrossBoss coronary catheter and Stingray CTO system (Boston Scientific) for coronary chronic total occlusions (CTOs), and the Viance crossing catheter and Enteer re-entry system (Covidien) for peripheral CTOs.
Methods: We performed a systematic review of the literature on the BridgePoint system published between October 2008 and August 2014, in accordance with the standards set forth in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement.
Results: We identified a total of 20 studies: 12 studies on coronary CTOs (10 retrospective with 2 prospective case series) and 8 studies on peripheral CTOs (all retrospective).
Effect of a real-time radiation monitoring device on operator radiation exposure during cardiac catheterization: the radiation reduction during cardiac catheterization using real-time monitoring study.
Circ Cardiovasc Interv
December 2014
Background: The Radiation Reduction During Cardiac Catheterization Using Real-Time Monitoring study sought to examine the effect of a radiation detection device that provides real-time operator dose reporting through auditory feedback (Bleeper Sv; Vertec Scientific Ltd; Berkshire, UK) on patient dose and operator exposure during cardiac catheterization.
Methods And Results: Between January 2012 and May 2014, 505 patients undergoing coronary angiography, percutaneous coronary intervention, or both were randomized to use (n=253) or no use (n=252) of the Bleeper Sv radiation monitor. Operator radiation exposure was measured in both groups using a second, silent radiation exposure monitoring device.
Background: Aortocoronary dissection can complicate percutaneous coronary intervention (PCI) of chronic total occlusions (CTOs).
Methods: We retrospectively examined the frequency and outcomes of aortocoronary dissection among 336 consecutive CTO PCIs performed at our institution between 2005 and 2012 and performed a systematic review of the published literature.
Results: Aortocoronary dissection occurred in six patients (1.
Objectives: This study sought to perform a weighted meta-analysis of the complication risk during chronic total occlusion (CTO) percutaneous coronary intervention (PCI).
Background: The safety profile of CTO PCI has received limited study.
Methods: We conducted a meta-analysis of 65 studies published between 2000 and 2011 reporting procedural complications of CTO PCI.
