As with any procedure involving the heart, complications can sometimes be fatal. However, this is rare with coronary angiography.

Next-generation CT scanner provides better images with minimal radiation
A new computed tomography (CT) scanner substantially reduces potentially harmful radiation while still improving overall image quality. National Institutes of Health researchers, along with engineers at Toshiba Medical Systems, worked on the scanner. An analysis of data on 107 patients undergoing heart scans found that radiation exposure was reduced by as much as 95 percent compared to the range of current machines, while the resulting images showed less blurriness, reduced graininess, and greater visibility of fine details.
