Surgical Repair of Mitral Insufficiency

A method of applying a pedicled pericardial graft under direct intracardiac digital control has been developed which is immediately effective in controlling serious mitral regurgitation of either pathological or surgical (during commissurotomy) origin. It is hoped and presumed that such grafts will prove permanently effective. Only the passage of time can finally prove this presumption. In seven human cases so treated there have been no deaths. One of the cases was not considered successful probably due to inaccurate positioning of the graft.
