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 .
