Surgical correction of aortic and mitral valve lesions: Results in a series of 105 patients who underwent valvular replacement with the Starr prosthesis

Abstract

Summary 1. Surgical correction of pure mitral stenosis under extracorporeal circulation was attended by gratifying results, with a mortality of 1.3 per cent. 2. Surgical treatment of aortic stenosis was satisfactory for the correction of congenital lesions, with a mortality of 5.3 per cent. Acquired aortic valve lesions corrected by valvulotomy and débridement had a higher mortality (19.9 per cent) and poor late results. 3. A series of 105 cases of aortic and mitral valve lesions were corrected by replacement with a Starr prosthesis, with an early and late mortality of 22.8 per cent. 4. In a group of 42 cases of aortic valve lesions, mortality was higher in patients with pure aortic stenosis. Aortic insufficiency was treated with low mortality (8.6 per cent). The mortality observed in aortic valve replacement was not increased by simultaneous open mitral commissurotomy. 5. Mitral valve replacement was performed in 43 cases with a mortality of 21.9 per cent. Myocardial failure was the outstanding cause of death. 6. In a group of 10 patients who underwent aortic and mtral valve replacement, extremely high mortality was observed. 7. Immediate and late postoperative courses of the patients in the present series are analyzed.
