Pressure-wire diagnostics

Location

Cardiac catheter suite, level 1, Royal Derby Hospital

About

A pressure wire is a device that can be used during coronary angiography to determine if a narrowing (stenosis) in one of your heart arteries (coronary arteries) requires further treatment. A pressure wire measures the pressure difference across a stenosis to determine if it reduces blood flow to the heart muscle.

Services

During coronary angiography, a catheter is inserted into an artery in the groin or wrist using a sheath and a guide wire. A pressure wire is a special guide wire which has a small sensor at its tip which measures blood flow and blood pressure.

The doctor positions the pressure wire beyond the coronary artery stenosis. Pressures are then recorded across the artery. A drug may be given to ensure the readings obtained are as accurate as possible.

The doctor can then decide if treating the stenosis with coronary angioplasty is suitable for the patient and what further treatment may be required.
