Intravascular Ultrasound (IVUS)

IVUS is based on the principle of sound waves and provides moving picture of the heart. It has transducer which sends the sound waves which are converted into picture of coronary arteries. It has a good resolution and high penetration. It helps the interventional cardiologist to characterise the lesion morphology, quantify plaque burden, guide stent sizing, assess stent expansion and identify complications. It also play the critical role to identify the mechanism of stent failure guiding appropriate therapy
