Figure Legends
Figure 1. Three-dimensional coronary computed tomography shows a MB at
the mid segment of the LAD (white arrow) (A). LAD is normal at diastolic
phase (B) and collapsed at systolic phase (C) in intraoperative
epicardial echocardiography.
Figure 2. Preoperative CAG shows a severe stenosis of the LAD
at systolic phase (A). Postoperative CAG shows no squeezing of the LAD
(B).
Figure 3. The LAD was buried in the myocardium for 25 mm from
the first diagonal branch (white arrowhead) (A). LAD was exfoliated all
around (white arrowhead) (B). LAD was exposed after surgical unroofing
(C). There were two ports for thoracoscopy that consisted of a 6-cm main
incision in the left 4th intercoastal space and a 1-cm
stabilizer incision in the 5th intercoastal space(D).
