Cerebral oxygenation impairment and S-100β protein release during off-pump coronary artery revascularization.

Objective: To elucidate the magnitude of global cerebral oxygenation impairment, using cerebral oxygenation indices and S-100β protein as potential markers, during off-pump coronary artery bypass grafting (OPCAB).

Design: Prospective cohort study.

Setting: Tertiary cardiac center.

Modified (Valsalva graft) aortic root reimplantation for successful repair of pulmonary autograft aneurysm after Ross procedure.

Dilatation of the pulmonary autograft after the Ross procedure is a possible complication, necessitating aortic valve replacement. We present a case of a patient who developed pulmonary autograft dilatation and was treated successfully with valve-sparing aortic root reimplantation with a Valsalva graft.
