Coronary CT angiography in percutaneous coronary intervention

Coronary CT angiography (CCTA) has become the non-invasive modality of choice for coronary imaging. It provides similar information to intravascular ultrasound (IVUS), but is less invasive and has fewer limitations. The availability of a three-dimensional data set allows the physician to assess the significance of a stenosis, thereby improving patient selection for percutaneous coronary intervention, and also impacts other areas such as procedural planning and identification of plaque and high-risk lesions. The three dimensional data set also consistently demonstrates totally occluded segments, facilitating opening of the occlusions with the aid of an advanced application that provides guidance for percutaneous intervention.
