Abstract

Palmaz-Schatz stents were implanted in 79 lesions in 76 patients, and serially expanded at 12, 15, and 18 atm of pressure using noncompliant balloons. By core lab analysis, intravascular ultrasound demonstrated marked stent expansion as pressure was raised, which was not apparent by angiography.
