Low Rate Fluoroscopy to Reduce Radiation Dose During Coronary Angiography and Intervention

Acute Coronary Syndrome Clinical Trial

Official title:
Low Rate Fluoroscopy at Reducing Operator and Patient Radiation Dose During Transradial Coronary Diagnostic Angiography and Interventions

Clinical Trial Summary

Objectives: To determine the efficacy of low rate fluoroscopy at 7.5 frames per second (FPS) vs. conventional 15 FPS for reduction of operator and patient radiation dose during diagnostic coronary angiography and percutaneous coronary intervention via the transradial approach.

Background: Transradial approach for cardiac catheterization is potentially associated with increased radiation exposure. Low rate fluoroscopy has potential to reduce radiation exposure.

Clinical Trial Description

Methods: Patients undergoing transradial approach diagnostic angiography ± ad hoc PCI, wil be randomized to fluoroscopy at 7.5 FPS vs. 15 FPS prior to procedure. Both 7.5 and 15 FPS fluoroscopy protocols will be configured with a fixed dose per pulse of 40 nGy. Primary endpoints will be operator radiation dose (measured with dosimeter attached to the left side of thyroid shield in µSv), patient radiation dose (expressed as dose-area product in μGy.m2), and fluoroscopy time. ;

Study Design

Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Health Services Research
