Mitral valve repair in patients over the age of 70 years.
The question of whether to repair or replace the mitral valve in the elderly remains unanswered. The purpose of our study is to describe our experience with mitral valve repair (MVR) using Carpentier's technique in patients 70 years and older. Fifty consecutive patients underwent MVR between 1984-1992. There were 30 female patients. All had 2 + or more mitral regurgitation (MR). The valve pathology included ischemic (n = 28), myxomatous (n = 7) and rheumatic (n = 6), leaflet prolapse (n = 11) and healed bacterial endocarditis (n = 3). The clinical findings included: myocardial infarction (n = 17), congestive heart failure (n = 18), atrial fibrillation (n = 14) and pulmonary hypertension (n = 10). The surgical technique involved placement of a Carpentier ring (n = 41) or Duran ring (n = 3), resection of leaflets (n = 9), shortening of the chordae (n = 8) and commissurotomy (n = 6). At surgery, coronary bypass was carried out in 32 patients while the aortic valve was replaced in five and repaired in one. Postoperative complications included atrial fibrillation (n = 14), transient neurologic events (n = 4), heart block requiring pacemaker (n = 3) and prolonged intubation (n = 4). Echocardiogram carried out postoperatively showed 2 + MR in three patients, 1 + in four, and a trace or none in the remaining (n = 39). No patient required re-operation for MR. Three patients (6%) died within 30 days after surgery due to low output (n = 1), malignant ventricular arrhythmia (n = 1) and heart block with cardiac arrest (n = 1).(ABSTRACT TRUNCATED AT 250 WORDS)
