Use of Large Field of View During Image Acquisition for Coronary Angiography

Preferential Use of Large Field of View During Image Acquisition for Coronary Angiography With Flat Detector Technology: a Simple Step to Reduce Radiation Exposure

Coronary angiography exposes patients and physicians to ionizing radiation. The purpose of this study is to evaluate the routine use of large field of view during image acquisition for coronary angiography. Patients with indication of diagnostic coronary angiography will be randomized for the use of either large field of view during image acquisition or medium field of view. Patients, physician and nurse radiation exposure will be measured by digital dosimeter.

Inclusion Criteria:

• Indication of diagnostic coronary angiography for suspected coronary artery disease
• Sign written consent form

Exclusion Criteria:

• Therapeutics procedures
• Urgency/emergency procedures
• Previous CABG
• Severe valvular disease
