| 21. | The heart has four valves and the other two are the mitral and the tricuspid valves.
|
| 22. | Mitral and tricuspid defects are opposite.
|
| 23. | In 1960, he performed one of the first-ever repairs of tricuspid valve regurgitation.
|
| 24. | In dogs, tricuspid valve dysplasia can be similar to Ebstein's anomaly in humans.
|
| 25. | The most common CHD include tricuspid valve regurgitation, atrial septal defects and patent ductus arteriousus.
|
| 26. | When the ventricular pressure is greater than the atrial pressure the tricuspid and mitral valves will shut.
|
| 27. | The tricuspid valve has three leaflets or cusps and is on the right side of the heart.
|
| 28. | The atrioventricular rings serve for the attachment of the muscular fibers of the bicuspid and tricuspid valves.
|
| 29. | The teeth are tricuspid and pleurodont, meaning they are attached to inner surfaces of the jaws.
|
| 30. | The closing of the mitral valve and the tricuspid valve constitutes the first heart sound ( S1 ).
