Morphometric study of the tricuspid valve in dogs.
An anatomical study of the tricuspid valve was performed in the hearts of 45 dogs using a method of dissection which preserves the integrity of the valve. Morphometrical criteria such as the width of the cusp base and larger depth of cusp and morphological criteria such as the number of tendinous cords, the perimeter of the fibrous ring and the properties of the papillary muscle were adopted for the characterization of a cusp. The tricuspid valve was not consistent with three cusps, but it was observed to present 2, 4 or 5 cusps in 68% of the cases.
