Abstract

A method and apparatus for replacing both the native mitral valve and the native aortic valve in a heart with a stentless bioprosthetic graft is provided. The bioprosthetic graft comprises a harvested homograft that includes a mitral valve portion and an aortic valve portion, and an extension portion made of a biocompatible material. The extension portion is sutured to the homograft and is for suturing to the left atrial wall of the heart to close an incision in the left atrial wall following implantation of the mitral valve portion and the aortic valve portion of the homograft.

Claims

1. A stentless bioprosthetic graft for replacing both the native mitral valve and the native aortic valve in a heart, said bioprosthetic graft comprising:

a harvested homograft that includes a mitral valve portion and an aortic valve portion; and

an extension portion made of a biocompatible material, said extension portion being sutured to said homograft and for suturing to the left atrial wall of the heart to close an incision in the left atrial wall following implantation of the mitral valve portion and the aortic valve portion of the homograft.

2. A method for replacing a native mitral valve and a native aortic valve with a single bioprosthetic graft, said method comprising the steps of:

harvesting a homograft that includes both a mitral valve portion and an aortic valve portion;

resecting the native mitral and aortic valve from the heart;

suturing a biocompatible extension portion to the homograft;

suturing the mitral valve portion of the homograft in place of the native mitral valve;

suturing the aortic valve portion of the homograft in place of the native aortic valve; and

suturing the extension portion to the left atrial wall of the heart to close the left atrial wall.
