BE CONFIDENT IN YOUR RESTING INDEX DECISION-MAKING with Abbott’s Pressure Wire™ X Guidewire: Abbott’s innovative sensor housing designs offers <1 mmHg/30 minutes with an 84% reduction in drift due to microbubbles.2
Drift is an issue that can lead to misclassification of stenosis.
There are two types of drift: wire-related (true drift) and procedure-related (apparent drift). While there are multiple causes of procedure-related drift, microbubbles (from residual air in device) are a major cause of drift5. Clinically significant drift is classified as ≥3 mmHg1
Drift affects the accuracy of most pressure measurement devices.3 Accuracy is particularly critical for resting indices, as clinical decisions from resting indices are more impacted by drift than FFR4,5. Compared to the hyperemic state, smaller separation between Pa and Pd at rest means it is critical to detect even the slightest difference of pressure.
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.
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.
