Mitral valve replacement in the elderly.
The results of elective mitral valve replacement between January 1978 and June 1982 in 35 patients aged over 70 are reported. The early mortality was 22,8% and late mortality 17,1%, after a mean follow-up of 25,1 months. Patient-related risk factors included chronic mitral stenosis, often after a previous closed mitral valvotomy, increased cardiothoracic ratio, pulmonary arterial hypertension, functional tricuspid incompetence and a raised left ventricular end-diastolic pressure.
