Preservation of anterior leaflet chordae with modified miki technique: how to do it.
During mitral valve replacement, total chordae preservation is very important for left ventricular functions. But leaving anterior leaflet and chordae may cause serious complications, such as left ventricular outflow tract obstruction and impairment in prosthetic valve functions. In this article, we present the anterior leaflet preservation technique by excising the central portion of the anterior leaflet. The rim of the leaflet tissue containing the marginal chordae was divided in two parts without destroying the chordae, and then the rim of leaflet tissue was sutured to the left atrium. This technique provided optimal chordae tension and improved avoidance of complications due to total chordae preservation, in mitral valve replacement operations.
