HAMANA, Leticia  and  BLANDENIER DE SUAREZ, Claudia. Caracterización histopatológica de la estenosis subvalvular aórtica: Estudio de 24 biopsias. RFM [online]. 2006, vol.29, n.1, pp.29-37. ISSN 0798-0469.

The subaortic stenosis is the left ventricular outflow tract obstruction caused by an excess of weaving or by congenital anomalies of any of the structures located under the valve aortica. With the objective to classify a group of biopsies, the macroscopic characteristics of subaortic stenosis are described and histopathologic of 24 biopsies proceeding from the University Hospital of Caracas, which they were analyzed with of routines and special histopathologics colorations and inmunohistochemistry. Finding that the majority of the cases they were of membranous or fibrous aspect, some they showed muscular fibers. The fibrosis was the hsitopathologic find more constant (100%), mixoide degeneration, smooth muscle, elastic fibers, neoformation vascular and inflammatory cells. Likewise corresponding heart muscle was observed a surgical bed. We conclude indicating the importance of a work as a group of the pathologist with the clinical one to classify these wounds, likewise, while more be known of its macroscopic, anatomical structure and histopathologic, more possibilities there will be of obtain evidences as for its etiopatogenia.
