Abstract

The influence of a coronary dissection on long-term outcome after PTCA has been controversely discussed in the past. Whereas diverse experimental studies have shown a positive relation between dissection and the incidence of restenosis, clinical trials could not document an influence of dissection on long-term outcome. However, most of the trials did not distinguish between the different morphologic configuration of the vascular dissection. Thus, the aim of the present study was to determine the influence of dissections on restenosis in regard to their amount and morphologic configuration. The prognostic importance of the National Heart, Lung, and Blood Institute classification on dissection as well as the importance of an additional classification of angiographic complications after PTCA were investigated to determine possible pathophysiologic mechanisms of the restenosis process. The study included 141 consecutive patients with 143 stable dissections after PTCA. A follow-up study was performed 13 months in mean after successful PTCA, which included clinical, symptomatic, and functional aspects of patients. In this patient population, type C dissections (Dorros et al.) showed a relevantly increased risk of a clinical adverse e...Continue Reading
