Comparison of fluoro and cine angiographic modes in coronary stenting procedure: A preliminary feasibility study

X-ray exposure of patient during coronary angiography (CA) and percutaneous coronary intervention (PCI) may have some deleterious effects. The radiation dose per frame for digital acquisitions can be 15 times greater than that for fluoroscopy. The number and length of digital acquisition or cine “runs” may be the greatest source of patient radiation dose in interventional cardiology procedures. Last fluoroscopy hold (LFH) is a new advanced feature that dynamically stores only the last current sequence of fluoroscopy images for instant replay, editing and storage in radiography and fluoroscopy systems without the need for operator pre-setting. LFH could reduce the fluoroscopy time to half compared to when it is not used and enables the operator to examine the image as long as necessary for decision making without the use of radiation [1–7].
