RÉSUMÉ
A 51-year-old woman, who had undergone mitral valve replacement with the Starr-Edwards ball valve 21 years ago, was hospitalized with cardiac failure. Preoperative cineangiograms showed delay of the ball movement during the early diastolic phase. Re-replacement of the mitral prosthetic valve with a CarboMedics prosthetic valve and tricuspid annuloplasty was successfully performed. The postoperative period after the initial implantation of the Starr-Edwards ball valve is the longest among patients reported in Japan. The cause of prosthetic valve insufficiency may have been granulomatous hyperplasia on the valve seat.
RÉSUMÉ
Surgical results in eight octogenarians who were operated upon for abdominal aortic aneurysms were compared to those of 42 patients under 80 years of age. Seven of eight octogenarians were operated on an emergency basis, and four of them were ruptured aneurysms. The size of the ruptured aneurysms was over 6cm in all cases of both groups. Postoperative complications occurred more frequently and postoperative mortality were significantly higher in octogenarians than in patients under 80. Early surgical intervention is recommended for elderly cases with large abdominal aortic aneurysms.
