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.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
