Mitral valve reconstruction in the elderly population

The technique, efficacy, and long-term results of mitral valve reconstruction have been well demonstrated and reported by Carpentier and other investigators. However, most of the results reported have been in patients aged less than 65 years. Between April 1985 and September 1988, we performed mitral valve reconstruction in 176 patients using Carpentier's classification and technique for repair. Ages ranged from 15 to 86 years (mean age, 63 years). Of the repairs, 96 / 176 (55%) had concomitant cardiac procedures. Patients aged 65 years or more accounted for 52% ( 92 / 176 ) of the population and 35% ( 65 / 176 ) were more than 70 years old. Hospital mortality (30 day) was 4% ( 4 / 84 ) in the group aged less than 65 years. Hospital mortality for the group aged more than 65 years was 12% ( 11 / 92 ), compared with an overall 8.5% mortality. These results suggest an increased morbidity with mitral valve repair in the patients aged more than 65 years, but this group represents an even higher risk group with mitral valve replacement.
