Use of Physiology Significantly Reduces Major Adverse Coronary Events
The CorMicA (Coronary Microvascular Angina) trial revealed that patients may benefit when coronary microvascular dysfunction (CMD) is accurately diagnosed and appropriately treated.1 Learn more about diagnosing and treating CMD.
RFR clinical evidence derives from assessing over 3,500 lesions in 2,000 patients, and much of that evidence is from ILUMIEN I + PREDICT, VALIDATE RFR, IRIS-FFR and RE-VALIDATE RFR.2-6
Fractional flow reserve (FFR)-guided percutaneous coronary intervention (PCI) is supported by more than 600 published studies including the FAME clinical trials.7-9
When integrated into cardiac cath lab procedures, measurement of FFR has been shown to reduce the incidence of major adverse coronary events (MACE) in patients being treated for complex coronary artery disease.7
The FAME study—evaluating complex lesions—examined FFR measured exclusively by the PressureWire™ X Guidewire. Results showed that compared to angiography alone, FFR:
- Allows more accurate identification of hemodynamically relevant stenoses8
- Reduces mortality or myocardial infarction by 34% at 2 years7
- Lowers procedure and 1-year follow-up costs by 14%10
- Does not increase procedure time8
- Decreases the amount of contrast agent used8
Precise measurement of intravascular diagnostics relies on the market-leading PressureWire™ X Guidewire that combines excellent maneuverability—even in tortuous vessels—and reliable readings11, all of which can ensure accurate information in the cath lab.

PressureWire™ X Guidewire
Indications: The PressureWire™ X Guidewire is indicated to direct a catheter through a blood vessel and to measure physiological parameters in the heart and in the coronary and peripheral blood vessels. Physiological parameters include blood pressure. The PressureWire™ X Guidewire can also measure blood temperature.
Contraindications: This guidewire is contraindicated for use in the cerebral vasculature.
Warnings:
- No modification of this device is allowed.
- The PressureWire™ X Guidewire is supplied sterile. Discard the guidewire if the pouch is opened or damaged, compromising the sterile barrier. The guidewire is designed for single use only and shall not be reused or resterilized. Adverse effects of using a non-sterile or resterilized guidewire may include, but are not limited to:
- Local and/or systemic infection
- Mechanical damage
- Inaccurate readings
- Observe all guidewire movements. Whenever the guidewire is moved or torqued, the tip movement should be examined under fluoroscopy. Never push, withdraw, or torque the guidewire if it meets resistance or without observing corresponding movement of the tip, otherwise vessel/ventricle trauma may occur.
- Torquing or excessive manipulation of the guidewire in a sharp bend, against resistance, or repeated attempts to cross a total vessel occlusion may:
- Cause dissection or perforation of blood vessels
- Cause vessel spasm
- Damage and/or fracture the guidewire
- When introducing the guidewire, flush the catheter and administer anticoagulation as for a standard catheterization procedure or clotting may occur.
- Do not use the guidewire in the ventricles if the patient has a prosthetic mechanical or biological valve. It may result in damage to both the prosthesis and the guidewire, which may cause injury or death.
- Use of the PressureWire™ X Guidewire in conjunction with interventional devices with a short rapid exchange may result in a folded or fractured guidewire.
- High frequency surgical devices must not be used on a patient at the same time as the guidewire.
Precautions:
- The PressureWire™ X Guidewire is a delicate instrument and should be handled carefully.
- Make sure that the transmitter is kept dry to ensure accurate pressure and/or temperature readings. Inaccurate readings may necessitate device replacement.
- Do not use the guidewire in conjunction with atherectomy catheters. It may damage the guidewire.
- Do not withdraw or manipulate the guidewire in a sharp-edged object. It may result in abrasion of the guidewire coating.
- Factors that may affect the accuracy of the diagnostic information include, but are not limited to:
- Improper placement of the aortic pressure sensor.
- Failure to achieve maximum coronary and myocardial hyperemia in FFR procedures.
- Blood flow affected by the position of interventional devices, such as balloon catheters.
- Guidewire readings may be affected by defibrillation. Rezero the guidewire after defibrillation use.
- Do not measure pressure when the guidewire sensor element is in a sharp bend or in contact with atrial or ventricular walls. It might result in pressure artifacts.
- Do not use the PressureWire™ X Guidewire together with another guidewire, for so called jailed wire technique, due to difficulty in guidewire withdrawal and possible guidewire entrapment.
- Store at room temperature (15°C – 25°C) in a dry and dark place.
Potential Adverse Events: Potential complications which may be encountered during all catheterization procedures include, but are not limited to: vessel dissection or occlusion, perforation, embolus, spasm, local and/or systemic infection, pneumothorax, congestive heart failure, myocardial infarction, hypotension, chest pain, renal insufficiency, serious arrhythmias, or death.
In addition, this device has a coating containing Polyethylene Glycol (PEG); potential allergic reactions (anaphylaxis) may occur during the interventional procedure if the patient is allergic to PEG.
