1 In patients with chest pain, coronary angiography alone does not accurately determine whether or not there is reversible myocardial ischaemia. The RIPCORD concept proposes routine pressure wire ...

As a rule, revascularization is indicated only when coronary artery stenoses cause relevant ischemia, but this cannot be determined unequivocally by angiography alone. Pressure wire measurement ...

Opens in a new tab or window Stenting guided by quantitative flow ratio (QFR), derived from angiography without a pressure wire or use of drugs to induce hyperemia, improved major adverse ...

In a 2009 study involving 1,000 patients in the U.S. and Europe, patients who underwent an angiogram with the additional pressure wire technique received a third fewer stents than those examined ...

They will then insert a catheter into the blood vessel using a guide wire and ... of invasive angiogram may include bleeding at the wound site that does not stop with firm pressure.

to register iFR measurements onto the angiogram to identify vessels that require treatment. The wire uses conductive ribbons within its outer polymer layer to convey pressure information ...

A routine strategy that assesses function of all epicardial vessels at the time of diagnostic angiography in patients with new-onset chest pain doesn’t cost any more than conventional diagnostic ...

Traditional pressure wires use a hollow metal tube (hypotube) to house the wiring that transmits the ... (ESC), the Society for Cardiovascular Angiography and Interventions (SCAI) and the American ...

By contrast, QFR can be derived from three-dimensional coronary artery reconstruction and fluid dynamics from the angiogram, thereby estimating FFR without the use of a pressure wire or hyperemic ...
