Cerebral Protection During Mitral Valve Repair in a Patient With Moyamoya Syndrome.

In patients with moyamoya syndrome requiring heart surgery, the brain blood flow during the low perfusion state under cardiopulmonary bypass is a concern. We report on a successful mitral valve repair and tricuspid repair in a patient with moyamoya syndrome, performed using an integrated cerebral protection strategy with cerebral oxygen saturation monitoring, intraaortic balloon pumping, and cardiopulmonary bypass perfusion at a relatively high pressure. An integrated approach with a thorough discussion among cardiac surgeons, anesthesiologists, and perfusionists was invaluable to protect brain perfusion in a patient with moyamoya syndrome.
