RESUMEN
We report the case of a 67 years old woman diagnosed of CREST syndrome (calcinosis, Raynaud's phenomenon, esophageal dysfunction, sclerodactyly, telangiectasias) variant of generalized scleroderma, that suffered a Brucella endocarditis on mitral valve affected by the primary disease. We examine the cardiac lesions in progressive systemic sclerosis, pointing up the rare involvement of the valves, together with the evolution and treatment of Brucella endocarditis, uncommon entity.

During the last 12 years, we have used a modified suture technique for aortic valve replacement in 450 patients in order to avoid periprosthetic leaks. There were 420 survivors, and reoperation for periprosthetic leaks was necessary in no instance. The "secret" of our technique consists of the uniform distribution of the tensile forces among all sutures, eliminating uneven stresses that favors tearing of the tissues or rupture of the stitches.

The term parchment heart is used to describe partial to nearly complete loss of ventricular myocardium. We report the first case of transposition of the great arteries with almost total absence of left ventricular myocardium. The latter was not recognized and the child underwent Mustard's operation at four months of age. He died on the operating table. At necropsy, the left ventricular wall was 1 mm in thickness; microscopic examination revealed few myocardial fibers within edematous connective tissue.

A case is presented in which the outlet strut of a Björk-Shiley mitral prosthesis (convexo-concave, 60 degree orifice opening) fractured 10 months postoperatively. Emergency reoperation was successful.

A suture technique which avoids periprosthetic leakage during replacement of the aortic valve is described. Three types of stitch are inserted in a manner that causes all needle points to exit in a straight plane. The method was employed in 106 consecutive patients; of the 99 who survived operation, none have developed perivalvular leak.
