Methods
Patients : We retrospectively studied 156 cases (74 males and 82
females) who underwent trans-jugular transcutaneous closure of ASD with
an adjustable curved sheath under echocardiography guidance in the Heart
Center of Henan Province People’s Hospital from January 2016 to December
2022. All patients were diagnosed with ASD by echocardiography.
According to the guidelines for interventional treatment of congenital
heart disease(13) . The inclusion criteria were as
follows: 1) secundum ASD; 2) increased right ventricular volume load; 3)
left-to-right shunt; 4) in addition to the absence or insufficiency of
the stump margin of atrial septum on the aortic side, the stump margin
of the superior and inferior vena cava, the stump margin opposite the
aortic root, and the stump margin of the mitral valve annulus should be
≥ 3 mm; 5) the maximum extension diameter of the atrial septum was
larger than the left atrial surface diameter of the selected occluder.
The exclusion criteria were as follows:1) primum ASD; 2)Severe pulmonary
hypertension; 3)age < 6 months; 4)the stump margin of the
superior and inferior vena cava, the stump margin opposite the aortic
root, and the stump margin of the mitral valve annulus should be
< 3 mm
All patient and family members were informed and agreed to performance
of this operation.
Intraoperative TEE was performed using GE Vivid EQ5 portable
ultrasonography (GE Healthcare Biosciences, Piscataway, NJ, USA). The
occluders and adjustable bent sheaths were produced by Shenzhen LifeTech
Scientific Corporation China. The conveying device included loading
sheaths and push cables (Figure 1).
