Patient characteristics
In total 156 patients were included, 74 males and 82 females. The mean
age was 6.9 ± 7.4 years and mean weight was 23.7 ± 14.6 kg. There were
114 cases with different levels of tricuspid regurgitation. The baseline
characteristics and perioperative information are shown in Table 1.
Perioperative results
The mean size of the ASD was 9.7 ± 4.7 mm, and the occluder was 14.1 ±
5.7 mm. The mean length of the superior vena cava rim, inferior vena
cava rim, aortic rim, posterior rim and atrioventricular valve rim were
8.5 ± 4.0 mm, 11.4 ± 4.3mm, 1.8 ± 2.2 mm, 9.3 ± 3.4 mm, and 9.1 ± 3.2
mm. Tricuspid regurgitation was 1.1 ± 1.0 cm2 and mean
pulmonary artery pressure was 30.9 ± 9.4 mmHg. The type of bent sheath
was 8.3 ± 1.6 F. The operation time(From puncture right internal
jugular vein to leaving the operating room) was 49.6 ± 29.2 min, the
ICU time was 6.9 ± 8.3 h, the ventilator time was 1.2 ± 1.5 h. No case
required blood transfusion. All patients were occluded successfully.
There are 3 patient had a small residual shunt of 1-2mm. The residual
shunt had disappeared at the 3-6-12month follow-up. There were no
complications such as atrioventricular block, pericardial effusion,
thromboembolism, hematoma at puncture site and arteriovenous fistula.
