Figure 1. Pre- (A) and post-operative (B) computed tomography
images in end-diastolic phase of patient 3. The vertebral-apex angle
(preoperative: α; postoperative: β) is defined as the angle between the
line perpendicular to the vertebral body and that from the vertebral
body to the apex. The arrows indicate the left lower pulmonary veins; it
is normal in (A) and diffusely stenotic in (B).
Figure 2. Cumulative survival rate after TAPVC repair. TAPVC,
total anomalous pulmonary venous connection.
Figure 3. V-A angles before and after the operation. (A) The
change in V-A angle after the operation. (B) Differences in the
preoperative V-A angles (α) between the non-PVO and PVO groups. (C)
Differences in the postoperative V-A angles (β) between the non-PVO and
PVO groups. The V-A angles of the patients in the PVO group were 42° or
more, while those in the non-PVO group were 40° or less. The dotted line
presented the cut off value of 41°. (D) The ratio of post- and
preoperative V-A angles (β/α). The ratios of the patients in the PVO
group were 1.18 or more, while those in the non-PVO group were 1.15 or
less. The dotted line presented the cut off value of 1.17. Values are
median and interquartile range. PVO, pulmonary venous obstruction; V-A,
vertebral-apex.
