Operative Characteristics
Operative characteristics are presented in Table 2. Cardiopulmonary bypass time was similar between the two groups (CVG vs PAR, 228±19 vs 211±34 min, p=0.678), as was aortic cross clamp time (197±16 vs 210±19, p=0.291) and circulatory arrest time (19±4 vs 22±5, p=0.328).
Similarly, cannulation strategy was also comparable, with n=12 vs 9 (CVG vs PAR) receiving femoral cannulation, and n=8 vs 10 (CVG vs PAR) receiving axillary cannulation. Two patients in either group underwent a hemiarch replacement, whereas 3 patients required a total arch replacement in the CVG group, compared to none from the PAR group.
