Transcatheter closure of atrial septal defect in a patient with absent inferior caval vein connection: a novel technique using a steerable guide catheter

Analysis of the therapeutic effect of transesophageal echocardiography-guided percutaneous device closure of atrial septal defects via the right internal jugular vein in children

BACKGROUND

Traditional X-ray-guided transcatheter closure of atrial septal defects (ASDs) via the right femoral vein carries a risk of radiation damage, which is greatly exacerbated by age and vascular conditions. Transesophageal echocardiography (TEE) guidance for the closure procedure not only broadens the indications of interventional therapy for ASDs but also avoids radiation exposure.

PURPOSE

To assess the value of TEE-guided ASD device closure via the right internal jugular vein (RIJV) in children.

METHODS

Nineteen pediatric patients with secondary ASD underwent TEE-guided ASD device closure via the RIJV from July 22, 2015 to July 19, 2017. After the RIJV was successfully accessed, one Fustar curve-adjustable delivery sheath was inserted. The implant depth was adjusted, and the tip of the sheath was curved to facilitate passage through the ASD for the delivery and release of the occluder. TEE was used to guide the entire procedure.

RESULTS

In all 19 patients, the ASDs were successfully closed and the occluder was confirmed to have a stable position and good shape, with no residual shunt. During the follow-up period (2 months to 2 years), no pericardial effusion, thrombosis, tachyarrhythmia, atrioventricular block, or other complications were observed.

CONCLUSIONS

An adjustable delivery sheath can be used to treat ASD via the RIJV. This procedure has varied indications, and its advantages include a short operation path, procedural accuracy, minimal trauma, and quick recovery, especially for young patients with large ASDs and cases in which a femoral vein approach is difficult. The procedure has great clinical significance and merits attention.
