Abstract
Aortic valvuloplasty for calcific aortic stenosis requires the removal of large calcified plaques from the leaflets, particularly at the hinge areas at the bases of the leaflets, and opening the commissures to the annulus. By this technic the leaflets are made flexible, and an adequate and competent valve can be obtained in the large majority of instances. Extracorporeal circulation combined with general body hypothermia and selective hypothermia to the heart is an ideal method for this procedure, and it offers maximum protection to the patient. Additional protection for the heart can be obtained with intermittent coronary perfusion We have used this technic of aortic valvuloplasty in a consecutive series of sixteen patients with calcific aortic stenosis. Three patients died, a mortality rate of 19 per cent; ten patients have had an excellent result, two a good result and one a fair result.
