Abstract
The patient-prosthesis mismatch has been reported as an important cause of adverse
outcome following aortic valve replacement. The relief of patient-prosthesis mismatch
generally requires a reoperation of comprehensive nature, which necessitates an extensive
aortic root enlargement. The Konno aortoventriculoplasty represents an efficient treatment
option, as this technique provides both extreme root enlargement and relief of the
frequently associated subvalvular obstruction. However, the application and conduct
of the procedure may somewhat differ from the pediatric Konno procedures. This article
describes our surgical technique adaptation in Konno-aortoventriculoplasty for adult
patient-prosthesis mismatch cases, highlighting the differing points from the pediatric-Konno.
