Angioplasty performed to open a narrowed coronary artery, in which a balloon-tipped catheter is inserted into an artery in the groin or shoulder and threaded to the affected part. The balloon is inflated to flatten atherosclerotic plaque against the artery wall and reopen the artery.

Table 1 gives the measured values of permittivity, tan[Delta] and the [d.sub.33]- coefficient of the two composites PTCa/P(VDF-TrFE) and PTCa/epoxy (14) and of the ceramic PTCa. The values of the piezoelectric figure of merit, [(FOM).sub.piezo], were calculated using the measured values of [d.sub.33] and [[Epsilon].sub.r] from

PTCA dilatation catheters are used in coronary angioplasty and stenting procedures to open arteries blocked by atherosclerosis, which if left untreated can cause heart attack and stroke.
A virtually identical absolute difference in survival was seen after 7 years in the Bypass Angioplasty Revascularization Investigation (BARI) trial, with 84% of CABG patients and 81% in the PTCA group remaining alive.
Twenty-seven patients had PTCA. Heparin was injected into femoral arteries at a dose of 50 units/kg for CAG and 200 units/kg for PTCA.
Background In patients with anterior MI or extensive nonanterior MI, prompt PTCA is superior to intravenous thrombolysis in preventing reinfarction and death.[1] It is not yet clear, however, whether patients presenting with signs and symptoms of less extensive coronary ischemia will benefit more from PTCA than from immediate thrombolytic therapy.
Background Many of the 600,000 North American patients who undergo coronary revascularization each year are candidates for either PTCA or CABG.[1] The BARI Trial recently reported that with respect to the risk of myocardial infarction (MI) or death in the first 5 years after the procedure, the two procedures were equivalent.(2) This article reports the clinical and functional outcome for the same patients.
