Paper Abstract

Calcified human coronary arterial segments obtained at necropsy were irradiated in vitro with continuous wave (CW) argon laser (n=16) and a pulsed (P) excimer laser (n=28). CW laser irradiation accomplished little debridement of calcified plaque. P laser irradiation accomplished extensive ablation of calcific plaque, but was associated with more particulate photoproducts. The quantity and size of the resultant particles varied as a function of the pulse energy employed. Reduction in pulse energy from 80 to 15 mJ/pulse decreased the quantity of particulate debris by 50% and eliminated the largest (>700 microns) particles.
