Mitral Stenosis by Duran Ring in Children: Two cases report / 대한흉부외과학회지

ABSTRACT

Mitral stenosis was developed after Duran ring annuloplasty in two growing children during follow up period of 8 years and 5 years respectively, which may be due to pannus overgrowth and patient's growing. Only removal of pannus and prosthetic ring has resulted in complete relieving of Mitral stenosis. With time, even adult-sized annuloplasty ring may induce stenosis in growing children.
