PURPOSE: The number of elderly patients who require surgical treatment for mitral regurgitation (MR) is increasing. However, the feasibility and efficacy of mitral valve repair in elderly patients are unclear.
METHODS: We retrospectively reviewed 55 patients, aged ≥75 years, who underwent mitral valve repair for degenerative MR between 1991 and 2011. All patients were followed up for 4.7 ± 3.4 years.
RESULTS: The patients aged ≥75 years were more symptomatic and had a higher incidence of persistent atrial fibrillation and pulmonary hypertension than those aged <75 years. Thirty-day and in-hospital mortality was 1.8% and 7.3%, respectively, and the 5-year survival rate was 81.6% ± 5.8%. The leading cause of late death was stroke, which primarily occurred in patients with postoperative atrial fibrillation. Except for a single failure of repair due to technical reasons, there was no recurrence of severe MR or reoperation on the mitral valve. In the late follow-up period, the mean left ventricular diastolic diameter significantly decreased and the mean left ventricular ejection fraction was approximately 60%. Most patients had mild symptoms at follow-up.
CONCLUSION: Mitral valve repair can provide satisfactory early as well as long-term outcomes and can preserve left ventricular function even in the elderly.
