★ ★ ★ ☆ ☆

The pressure wire has a pressure sensor near the end. The wire is introduced into the coronary artery and negotiated accross the narrowed artery. Following this the difference between the pressure measured in the artery beyond the narrowing is compared with that in the aorta (main blood vessel).

★ ★ ★ ★ ☆

A coronary pressure wire test is a coronary catheterization procedure in which a thin tube (called a catheter) is threaded through an artery up toward your heart. It can help show whether a narrowed section of a coronary artery is likely to cause problems in the future.

Can Pressure Wire Really Help Reduce Heart Attack Risk ...

★ ★ ☆ ☆ ☆

However, Pressure Wire technique has some risks too. It is an invasive procedure that is done during a heart disease patient is undergoing a coronary angiogram. In very rare instances, threading wire into the blood vessel could cause disruption to the plaque building up in the artery thus triggering a heart attack.

Fractional flow reserve - Wikipedia

★ ★ ★ ★ ☆

Fractional flow reserve (FFR) is a technique used in coronary catheterization to measure pressure differences across a coronary artery stenosis (narrowing, usually due to atherosclerosis) to determine the likelihood that the stenosis impedes oxygen delivery to the heart muscle (myocardial ischemia).

Hi poppy111. A pressure wire study is done in the same way as an angiogram, so you will be familiar with the process from your stents. The cardiologist guides a wire to your heart with a sensor on the end, then takes a blood pressure reading inside the artery above a narrowing, and below it to see if there are any differences in the readings.

We present a case of chronic mesenteric ischemia in a 70-year-old woman who had abdominal pain with multiple possible causes. We used a 0.014-in pressure wire to calculate pressure gradients and guide our decision to stent tandem lesions in the superior mesenteric artery. After revascularization, the patient's symptoms improved dramatically.

The instantaneous wave-free ratio can also be calculated on a beat-to-beat basis. If performed during the slow withdrawal of a pressure wire (referred to as 'pullback') under resting conditions, it is possible to plot the change of iFR or trans-stenotic gradient over the wave-free period throughout the vessel.
