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 ...

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 ...

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 ...

Most doctors depend on angiography (X-rays of the coronary ... Outcomes can be improved if lesions to stent are selected using a pressure wire to identify which are obstructing blood flow.

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.

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 ...

FFR is easily measured during routine coronary angiography by using a pressure wire. It is an add‑on test for PCI. NICE's guideline on managing stable angina recommends coronary angiography to guide ...

We assigned 1201 patients to OCT-guided PCI (600 patients) or angiography-guided PCI (601 ... functional test with imaging or a pressure-wire–based method or other objective documentation ...
