Using intravascular imaging (IVI) to guide stent implantation during complex stenting procedures is safer and more effective ...

Stents are placed through a cardiac angiogram, a procedure in which a catheter is placed in the groin and run up to the heart. An angioplasty, in which the narrowed blockage of the artery is ...

Table 5 summarizes the mean velocities and ICA to CCA ratios for = 30 to < 50%, = 50 to < 70%, and = 70 to 99% in-stent restenosis, based on CT angiography. ROC Curves: Sensitivity and Specificity ...

A decade after the first introduction of angiography-derived fractional flow reserve (FFR), we are now entering an era in which simplified image-derived solutions could replace invasive assessment ...

The stent keeps arteries open, allowing the required drugs to be delivered and do their job. It then dissolves. Untreated ...

This prospective study revisits DUS criteria for determining the rate of in-stent restenosis. In analyzing a subset of 12 patients (pilot study) who had both completion carotid angiography and DUS ...

The stent keeps arteries open, allowing the required drugs to be delivered and do their job. It then dissolves. Untreated clogged arteries can cause leg amputations. Surgeons insert the ...
