Although many surgical procedures have been proposed to reduce the size of
a left atrium, their effectiveness is not well established. We present a ca
se of mitral and tricuspid valve insufficiency with a giant left atrium. Pa

eration with a successful outcome. This procedure can be an effective metho
d to treat giant left atrium. (Ann Thorac Surg 1999;67:1164-5) (C) 1999 by
