Video clip WB34 showing Pericardial Effusion at the Right Pericardial TFAST view. The FASTVet tenet is to always image toward the muscular apex of the heart away from heart chambers to support the diagnosis of pericardial effusion (PCE). We refer to this as the Bull’s Eye Sign because as the probe is directed along the short-axis of the heart the rounded sold gray muscular apex of the heart become surrounded by PCE – described in Focused Ultrasound Techniques for the Small Animal Practitioner, Wiley 2014.
The FASTVet tenet of imaging toward the muscular apex of the heart also takes place at the FAST DH view referred to as the Racetrack Sign – described in Focused Ultrasound Techniques for the Small Animal Practitioner, Wiley 2014.
