Catheter balloon valvuloplasty of stenotic porcine bioprosthetic valves: Part II: Mechanisms, complications, and recommendations for clinical use

Abstract

During the last several years dilating balloons have been applied in the treatment of stenotic cardiac valves. This interest has been extended to stenotic porcine bioprosthetic valves. Part I of this review discusses the pathologic changes producing stenotic porcine prosthetic valves. Part II of this review describes an in vitro study of porcine prosthetic valve valvuloplasty defining the mechanisms, complications, and clinical applications. Results of this study indicate a limited and cautious role in balloon dilation of stenotic bioprosthetic valves. Copyright © 1991 Wiley Periodicals, Inc.
