The use of embolic protection devices (EPD) during percutaneous cardiac procedures has helped reduce the number of complications due to debris being released into the bloodstream and causing blockages in smaller vessels. The devices are designed to capture and remove debris that may be dislodged during procedures. There are three classes of EPD devices:

If the case went to court for whether positron emission tomography (PET) or single, photon emission computed tomography (SPECT) is better suited for myocardial perfusion imaging, experts say the current technology and developments on the horizon would result in a hung jury.
