31. Right ventricular outflow tract tachycardia originates from the outflow tract of the right ventricle or the tricuspid annulus. 32. In the radula, the first bilateral teeth are bicuspid but occasionally they are tricuspid or rarely quadricuspid. 33. Marginal teeth are bicuspid or tricuspid with blunt inner cusp and shallow incision between the inner two cusps. 34. Isom replaced the mitral valve with a tissue valve and performed a ring annuloplasty to repair the tricuspid vale. 35. Some tricuspid valve regurgitation was shown after the procedure that could possibly be due from the right ventricular disc. 36. In addition to the possible ausculatory findings above, there are other signs indicating the presence of tricuspid regurgitation. 37. Surgical tricuspid valve replacement for severe stenosis ( blockage of blood flow ) has been necessary in some patients. 38. Next, the atrioventricular valves are identified, with the tricuspid valve slightly more apical than the mitral valve. 39. This increase in pressure causes blood to flow back toward the atria, closing the tricuspid and mitral valves. 40. Tricuspid atresia is the complete absence of the tricuspid valve which can lead to an underdeveloped or absent right ventricle.
