SANTIBANEZ ESCOBAR, Felipe. Surgical treatment of aortic stenosis in small aortic annulus. Arch. Cardiol. Méx. [online]. 2006, vol.76, suppl.2, pp.117-123. ISSN 1665-1731.

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.
