SIR LAUDER Brunton1 wrote in 1902:
Mitral Stenosis is not only one of the most distressing forms of cardiac disease, but in its severe forms it resists all treatment by medicine.... The risk which an operation would entail naturally makes one shrink from it, but in some cases it might be well worthwhile for the patients to balance the risk.
The first question that arises is whether the mitral orifice should be enlarged by elongating the natural opening or whether the valves should be cut through their middle at right angles to the normal opening. I think there can be little doubt that the former would be the better plan, but the latter is the more easily performed (Fig. 1).
The good results that have been obtained by surgical treatment of wounds in the heart emboldens one to hope that before very long similar good results may be obtained
