Surgery for mitral and tricuspid insufficiency associated with secundum atrial septal defect
M Shigenobu, JH Kay, M Mendez, P Zubiate, N Vanstrom and T Yokoyama
Pure mitral insufficiency associated with secundum atrial septal defect is
not an unusual finding. Thirteen patients with significant mitral
insufficiency and an associated secundum defect were operated upon. Two of
these patients also had severe tricuspid insufficiency. The mitral valve
was repaired in 12 patients and replaced in one. The tricuspid valve was
reapired in the two patients with associated tricuspid insufficiency. There
were two early deaths due to mediastinitis and one late death due to a
cerebral embolus in the only patient who had valve replacement; this
patient died 3 years after the operation. It is concluded that mitral and
tricuspid valve repair should be performed for patients with significant
mitral and tricuspid insufficiency associated with atrial septal defect of
the secundum variety. Replacement of the values should be avoided if
possible.
