3.2 Procedural outcomes
In intention-to-treat analysis, a significant reduction in the
cross-clamp time, CPB time and operative time was observed in the FLS
group compared with the conventional group (Table 2). The ratio of
continuous suture implantation of a bioprosthetic valve was also
significantly higher in the FLS group than that in the conventional
group (27/30 vs 5/30, p<0.001). There was no significant
difference in implanted valve size between two groups. In per-protocol
analysis, the two groups showed
comparable procedural outcomes .
