The Journal of Thoracic and Cardiovascular Surgery, 1965 SUMMARY This paper summarizes the experience in the treatment of a series of 1,370 cases of open-heart surgery. Of these, 964 valvular lesions and the associated pathologic lesion are analyzed. Details of correction and immediate and late results in the treatment of the following groups of lesions were studied: 74 cases of congenital aortic stenosis ...
