title: Intracoronary radiation with a 32P source wire.
abstract: The Proliferation REduction with Vascular ENergy Trial (PREVENT) is a prospective randomized study of the safety and efficacy of intracoronary brachytherapy to reduce restenosis. A beta-emitter, 32P, is embedded on a wire tip and delivered to the target site through a centering catheter immediately following a coronary intervention. The radiation doses are 16, 20, and 24 Gy measured at 1 mm within the vessel wall. Follow-up includes an angiogram and IVUS at 6 months. Phase I of this trial has been completed with results expected in early 1999.
