Study Population and Definitions
This was a retrospective review of patients from January 2009 to
November 2021 at Guangdong Provincial People’s Hospital. This study was
approved by the Guangdong Provincial People’s Hospital Institutional
Review Board. The requirement for individual patient consent was waived.
Data was obtained from a review of hospital charts and medical records.
During this period, a total of 1713 patients were diagnosed with TOF at
our institute. 8 cases of TOF with UAPA were enrolled, excluding
patients with intra-pericardial unilateral pulmonary artery occlusion or
unilateral pulmonary artery originating from the aorta. The absent
pulmonary artery in all patients was on the left side. Baseline
demographics and patient characteristics are presented in Table 1, and
the CT 3D print models of the pulmonary artery are shown in Figure 1.
