Patient characteristics
Table 1 shows the patient characteristics. The fetal diagnosis
of TAPVC was conducted for all patients. Stent dilation was performed as
the first palliative procedure for an obstructive vertical vein in seven
patients. The median age and bodyweight of the patients at TAPVC repair
were 102 days and 3.8 kg, respectively. The type of TAPVC was
supracardiac in 14 patients, infracardiac in two, and mixed type in two.
Seven patients had dextrocardia, while 11 had levocardia. The aortic
arch position was left in seven patients and right in 11 patients.
Concomitant procedures performed with TAPVC repair were Blalock Taussig
shunt (BTS) in two patients, PA banding (PAB) in four patients, Glenn
procedure in 11 patients, and right ventricle-PA (RV-PA) conduit
placement in one patient. There were no significant differences in
patient background and surgical procedures between the groups.
