Coronary Computed Tomographic Angiography Can Predict Chronic Total Occlusion Recanalization Success

Usefulness of Intraprocedural Coronary Computed Tomographic Angiography During Intervention for Chronic Total Coronary Occlusion.

Although intraprocedural coronary computed tomographic angiography (CCTA) allows for scanning during intervention without relocation of the patient, studies have yet to report on its use during chronic total occlusion (CTO) intervention. Therefore, we investigated the role of CCTA during CTO intervention, particularly whether CCTA could be used to evaluate the location of guidewires. A total of...

Coronary Computed Tomography Angiography Predicts Guidewire Crossing and Success of Percutaneous Intervention for Chronic Total Occlusion

Computed tomographic angiography and cerebral blood volume can predict final infarct volume and outcome after recanalization.

BACKGROUND AND PURPOSE Recanalization rates are higher in acute anterior stroke treated with stent-retrievers when compared with older techniques. However, some still have sizeable infarcts and poor outcome. This may be related to underestimation of core infarct on nonenhanced computed tomography (NECT). CT angiography (CTA) source images (CTASI) and CT perfusion may be more informative. We hyp...

Computed tomography angiography-guided recanalization of saphenous vein graft chronic total occlusion

Computed tomography (CT) angiography can augment conventional coronary angiography relative to length of vessel occlusion and quality of distal run-off. In this case report we describe the significance of CT angiography in the revascularization decision-making process of a patient following occlusion of both coronary artery bypass grafts.

"Role of CT Coronary Angiography in Recanalization of Chronic Total Occlusion"

Chronic total occlusion (CTO) is considered as the most challenging frontier in interventional cardiology and the last one to be conquered. With availability of state of art hardware, wires and catheters in particular and increased skills of the operators, the success rate for recanalization of CTO by percutaneous catheter intervention (PCI) has improved. Yet the complications rate and long-ter...
