Mortality and serious adverse events are summarized in table 3. One patient had smooth postoperative course without complications. The patient who had severe aortic insufficiency with coronary and intestinal malperfusion developed right ventricular dysfunction and required hemodyalisis post-operatively. He also developed right brachial plexus palsy with full recovery and totally relieved from intestinal malperfusion. The other patient with intestinal malperfusion developed hemorrhagic shock post-operatively with severe abdominal pain. An exploratory laparotomy revealed a huge hemoperitoneum that was drained. The patient who had neurological deficit developed multiple small cerebral emboli due to atrial fibrillation. He also developed ventilator-associated pneumonia and acute renal insufficiency requiring hemodialysis. His consciousness improved with time. No aortic reinterventions were needed. No aortic injury related to the device was noted. Mortality rate was zero at the post-operative day 30. Patients were discharged from the hospital after an average of 21 days.
