Uso del ultrasonido intravascular en las arterias coronarias

Transcatheter intravascular ultrasound (IVUS) imaging is a technique in which a miniaturized ultrasound transducer, mounted on the tip of a catheter, is inserted directly into an artery or vein to produce either 2- dimensional tomographic images or 3-dimensional computer-assisted reconstructions of planar IVUS images. As applied to intracoronary imaging, intravascular ultrasound is used as an adjunct to angioplasty, atherectomy, or placement of a stent. Intracoronary Doppler ultrasound, which provides a functional measure of flow across a coronary lesion, is addressed separately in Policy No. 6.01.19.
