[Heart insufficiency in aortic valve disease: prognosis and treatment].

The purpose of this paper is to review the mortality rate in patients with aortic stenosis, and the special subgroup of this pathology associated with left ventricular dysfunction and clinical data of heart failure. The left ventricular dysfunction is recognized by low aortic gradients, and differentiation must be made between reversible ventricular dysfunction, in which case the optimal treatment is surgery, and irreversible ventricular disfunction, since in these cases surgical treatment will have excessively high mortality rates and no benefit.

[Left ventricular myxoma].

Primary tumors of the heart are rare entities. We report a unique case of a young woman presenting a left ventricular myxoma, which manifested itself as coronary artery disease and was diagnosed by echocardiography. Emergency surgical treatment was indicated, done through a transeptal approach with extensive resection of the tumor, its pedicle and the papilar muscle to which it was attached as well as the anterior mitral leaflet, which was thinned and deformed by the presence of the mass. Mitral valve replacement was mandatory. A complete retrospective review of the literature is presented.

[Surgical treatment of aortic stenosis in small aortic annulus].

The purpose of this work is to demonstrate that the aortic enlargement procedures, first described for patients with small aortic annulus, are reproducible with excellent results. A retrospective revision of 72 cases in which an enlargement procedure was done, with consideration regarding the relationship between valve size and patient body surface area, in order to avoid prosthesis-patient mismatch, was done. We consider the immediate mortality of the group, differentiating the cardiac mortality, concluding with other authors that body surface areas between 1.3 and 1.7 m2 should receive aortic prosthesis larger than #23, which will eventually improve the late outcome of this population. We demonstrate that the aortic annular enlargement procedures can be safely done in our hospital, with a slight increase in mortality during the learning phase, but great benefit afterwards.
