title: Recent advances in hemodynamics: noncoronary applications of a pressure sensor angioplasty guidewire.
abstract: The use of the pressure sensor coronary guidewire is expanding into the peripheral circulation as well as into the realm of valvular heart disease. Small mechanistic studies and case reports have described the use of pressure wire technology in the renal and femoral arteries as well as in mechanical aortic valves. The use of this technology to measure hemodynamically significant stenoses in noncoronary locations will be discussed and a review of basic and more advanced hemodynamics in relation to problems encountered in clinical practice will be provided.
