Objective: Mitral valve repair is often preferred in elderly patients. In literature, has been described signi cant lower in-hospital stay, operative mortal- ity and cerebrovascular complications comparing mitral repair to mitral replacement. Our purpose was to assess the incidence of post-operative atrial brillation (POAF) in elderly patients that underwent mitral valve repair or replacement. Methods: 202 patients who underwent cardiac surgery for mitral insu ciency between January 2007 and December 2009 were retrospectively reviewed to recognize the incidence of POAF. Patients older than 75 years with no previous cardiac surgery were included in the elderly group and compared with a second group of patients younger than 75 years. Data were compared using t-Student test and a Mann-Whitney non-linear test. Results: Among the 41 patients over 75 years old (mean age 77,36±2,62), 20 underwent mitral valve repair, 21 mitral valve replacement. Preoperative permanent atrial brillation was not signi cantly di erent in the two groups (p>0,05). The incidence of POAF was 55% in the repair group and 67% in the replacement group with a p=0,46 (the new onset was 35% and 24% respectively, p=0,44). Considering the patients younger than 75 years old, new onset of POAF was 22% in mitral repair group and 19% in mitral replacement group (p=0,7). The incidence of stroke was 1% in the younger patient replacement group and 5% in the elderly patient replacement group; no cerebrovascular events were observed in the repair group. Conclusions: In elderly patients, there is no di erence in POAF comparing mitral repair to mitral replacement.
