Intravascular Ultrasound
Intravascular Ultrasound Inova cardiologists perform intravascular ultrasounds (IVUs) during cardiac catheterization. Like echocardiograms, IVUs use high-frequency sound waves (also called ultrasound) to produce an image of the coronary arteries. Sound waves are sent with a transducer device attached to the end of a catheter that has been threaded through an artery and into your heart. The sound waves bounce off of the walls of the artery and return to the transducer as echoes.
