The Gender Specific Effect on the Results of Ascending Aortic Replacement

Surgical access will be performed through a median sternotomy. Ascending aortic repair is performed under conditions of cardiopulmonary bypass (CPB) and MHCA with unilateral ACP via innominate artery with a flow rate of 8-10 ml/kg/min and perfusion pressure of 60-80 mmHg. Once CPB is instituted, the aortic cross-clamp is applied, and the heart is arrested with antegrade cardioplegia. Hemiarch replacement involves resection lesser curve of the aortic arch from the base of the innominate artery (Zone 0) to a point immediately distal to the nadir of the lesser curvature (Zone 3 or Zone 2 if the left subclavian artery was too far).
