The purpose of this study is to examine the impact of using a real time radiation exposure monitoring device on the patient and operator radiation exposure during cardiac catheterization. The hypothesis of the study is that use of a real time radiation exposure monitoring device during cardiac catheterization will decrease both patient and operator radiation exposure compared to no use of the monitoring device.

Radiation monitoring device (Bleeper Sv, Vertec Scientific Ltd, Berkshire, UK) that provides real-time auditory feedback on radiation exposure during cardiac catheterization
VA North Texas Health Care System
Dallas, Texas, United States
Radiation exposure of the operator
Radiation exposure of the operator (measured in mrem by the real time monitoring device)
Time frame: radiation exposure will be measured for the duration of the catheterization procedure, an expected average of one hour
Radiation exposure of the patient
Radiation exposure of the patient, as measured by the X-ray machine using (a) air kerma dose, (b) dose area product, (c) fluoroscopy and cineangiography time
Time frame: radiation exposure will be measured for the duration of the catheterization procedure, an expected average of one hour
