Comparison of neurocognitive functions after beating-heart mitral valve replacement without aorta cross-clamping and after standard mitral valve replacement with cardioplegic arrest.

Background: The aim of this study was to compare the postoperative long-term neurocognitive functions of patients who under-went beating-heart mitral valve replacement on cardiopulmonary bypass (CPB) without aorta cross-clamping with those of patients who underwent mitral valve replacement via the classic method.

Methods: The study group included 25 randomly selected patients who underwent beating-heart mitral valve surgery. During the same period, 25 patients were randomly selected as controls to undergo mitral valve replacement procedures via the standard ascending aorta-cannulation technique.

Neurocognitive functions after beating heart mitral valve replacement without cross-clamping the aorta.

Background And Aim Of The Study: Although neurologic outcome after cardiac surgery is well-established, neurocognitive functions after beating heart mitral valve replacement still needs to be elucidated. The aim of this study was to compare preoperative and postoperative neurocognitive functions in patients who underwent beating heart mitral valve replacement on cardiopulmonary bypass without cross-clamping the aorta.

Methods: The prospective study included 25 consecutive patients who underwent mitral valve replacement.

Neurocognitive functions after aortic arch repair with right brachial artery perfusion.

Background: Satisfactory neurologic outcome following aortic arch repair through right brachial artery perfusion is well established. However, how neurocognitive functions are affected following selective cerebral perfusion, still needs to be elucidated.

Methods: In a period between April 2002 and March 2003, 22 patients (19 male, 3 female, with a mean age of 46.
