21. Tricuspid atresia is the complete absence of the tricuspid valve which can lead to an underdeveloped or absent right ventricle. 22. The right side of the atrial canal will become the tricuspid valve and the left will become the bicuspid valve. 23. Endocardial cushion defects are associated with abnormalities of the atrioventricular valves ( the mitral valve and the tricuspid valve ). 24. Currently the most reliable concept for repair of a quadricuspid valve seems to be its conversion into a tricuspid valve . 25. When the atrium contracts, it sends the blood through a one way valve ( tricuspid valve ) into the right ventricle. 26. Tests confirmed Joanna had a rare heart condition called tricuspid atresia, meaning she was born without a tricuspid valve , her mother said. 27. Tricuspid valve regurgitation presents as a holosystolic murmur at the left lower sternal border with radiation to the left upper sternal border.28. Dysplasia of the mitral and tricuspid valves -also known as the atrioventricular ( AV ) valves-can appear as thickened, shortened, or notched valves. 29. Also during the operation, doctors repaired the tricuspid valve between the upper and lower chambers on the right side of the heart. 30. Ebstein's anomaly is the displacement of the septal leaflet of the tricuspid valve causing a larger atrium and a smaller ventricle than normal.
