Anatomic Variation of the Right Atrioventricular Valve / Variacion Anatomica de la Valva Atrioventricular Derecha (Case Report‪)‬

INZUNZA, H. O.; ORTEGA, F. W.; BERROCAL, C. C. & VARGAS, D. A. Anatomic variation of the right atrioventricular valve. Int. J. Morphol., 24(1):5-6, 2006. SUMMARY: Anatomic tradition uses the term "tricuspid" for the right atrioventricular valve, even though several studies had demonstrated a great variation in the anatomy of this structure. Some studies describe two valvules (or cusps), others describe six veils. Interestingly, it seems to be a direct relationship between the increment in the number of cusps and the patient morbid-mortality. This study present a right atrioventricular valve bicuspid, whit a clearly septal component with one valvule, and a mural component with a wide anterior valvule and a small anteroseptal commissural cusp.
