Use of PressureWire(R) Yields a More Accurate Assessment of Translesion Pressure Gradients in Peripheral Vasculature, Two New Studies Report

UPPSALA, Sweden, and WILMINGTON, Mass., March 28, 2008 /PRNewswire via COMTEX/ -- Use of a low profile PressureWire yields a more accurate assessment of translesion pressure gradients when compared to catheter-derived pressure gradient (CPG) measurements, according to a paper published in the Journal of Interventional Cardiology (2008; Vol. 20, Issue 1: 63-65).
The authors report that although CPG measurements derived from both a catheter and PressureWire correlated with anatomic stenosis, PressureWire gradient was more accurate in estimating the clinical significance of peripheral arterial lesions, thus reducing the risk of inappropriate intervention. The paper was based on a study of 20 lesions in 16 patients undergoing angiography for peripheral vascular disease.
Entitled "Physiologic Evaluation of Translesion Pressure Gradients in Peripheral Arteries: Comparison of PressureWire and Catheter-Derived Measurements," this study, conducted at the Beth Israel Deaconess Medical Center in Boston, is the first to assess this hypothesis in patients with peripheral arterial occlusive disease.
