median time was 90 minutes (interquartile range 66–130), with
a significant difference between patients implanted with one
(68 min, IQR 45–88) versus two clips (120 min, IQR 72–165)
respectively (P = 0.02). Comparison between the first and
second half of the cohort revealed a significant reduction in
median device time (71 vs. 129 min, IQR 45–93 vs. 83–165,
respectively, P = 0.02)
