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.

杂志文章abstract:BACKGROUND:Patients with acute myocardial infarction (AMI) and nonobstructive coronary artery disease (nonobCAD) may be perceived to be at lower risk for cardiac events, relative to those with obstructive CAD (obCAD), and thus less likely to receive optimal preventive medications in the year following AMI.
