The use of pressure-volume curves to assess the mechanism and adequacy of stenosis dilatation by balloon angioplasty.

Abstract

This report introduces a new technique for monitoring and understanding the mechanical events taking place during coronary balloon angioplasty. A standard inflation syringe is instrumented with transducers to record intra-balloon pressure and volume during stenosis dilatation. The theoretical and practical aspects of obtaining and interpreting PTCA… (More)
