An alternative method of prosthetic mitral valve implantation in the presence of extensive calcification

Abstract

Annular calcifications carry some technical difficulties for success in conventional valve surgery. In this paper we present an easy alternative mitral valve replacement method applied for a patient with a heavily calcified mitral annulus. Excision of both leaflets and partial resection of the annular calcification with an ultrasonic dissector allowed the intra-atrial insertion of a 33-mm Omnicarbon monoleaflet prosthetic valve through a smaller opening of the left posterior atrium. The technical difficulties in inserting a prosthetic valve in a patient with a heavily calcified mitral annulus are discussed.
