Mitral valvotomy in patients ≥50 may offer symptomatic relief; leaves open net benefit versus perioperative risk in degenerative comorbidities.
Mitral valvotomy is a well-established procedure and is indicated in patients who have symptoms due to rheumatic mitral stenosis. The risk of operation in the younger age group (up to 50 years of age) is now very low, but in older patients it is a more formidable undertaking with greater risks owing to associated degenerative heart and cerebrovascular disease. Furthermore, there is considerable controversy on how much benefit will accrue from mitral valvotomy in this age group. It was for these reasons that a retrospective study was carried out of all patients aged 50 and over who had mitral valvotomy performed in the cardiothoracic unit at Mearnskirk Hospital.
