title: Mitral valve replacement in the elderly.
abstract: 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.
