Simple supra-annular prosthesis insertion for dialysis patients with extensive mitral annular calcification.

Abstract

This simple supra-annular prosthesis insertion technique was safely and easily performed with minimum debridement of the calcified annulus in five dialysis patients. The technique may represent an alternative approach for high-risk patients with extensive MAC. The SJM valve, with its hinge protruding into the atrial side, is suitable for use in this technique.
