Abstract
Parachute mitral valve (PMV) is a congenital heart anomaly which consists of a unifocal attachment of the mitral valve chordae into a single or dominant papillary muscle. This morphological anomaly determines the impairment of mitral leaflet motion, resulting in different grades of mitral stenosis. Due to its frequent association with other congenital cardiac defects requiring surgical correction, the therapy of a relevant stenotic PMV is usually represented by surgical commissurotomy. Herein is reported the case of a PMV treated by surgery in infancy, which showed a severe restenosis after 34 years and was successfully treated by percutaneous valvuloplasty with the additional creation of a restrictive atrial communication.
