Paper Abstract

Restenosis remains the greatest limitation to the success of conventional and newer forms of angioplasty for the treatment of coronary artery disease. Since the armamentarium available to the clinician is presently limited to mechanical forms of intervention, invariably causing an acute response to injury, a pharmacologic alternative is sought. Photodynamic therapy has the potential to provide a combined drug/device therapy to significantly reduce the rate of restenosis through selective cytolysis and cytostasis. In this study Tin Ethyl Etiopurpurin, a second generation photosensitizer, demonstrated selective retention in catheter induced atheromatous plaques in a New Zealand White rabbit model in vitro and in vivo.
