Abstract
BACKGROUND: Percutaneous atrial septal defect (ASD) closure is the preferred treatment for patients with suitable ASD anatomy. The safety and effectiveness of transcatheter closure have been established. However, reports on transesophageal echocardiography (TEE)-guided percutaneous closure of ASD via the right internal jugular vein (RIJV) are limited. The study aims to discuss the safety and effectiveness of percutaneous trans-jugular vein closure of ASD. METHODS: We conducted a retrospective analysis of patients (n=103) with secondary ASD who underwent surgical treatment in the Department of Cardiovascular Surgery, the Second Hospital of Jilin University between July 2015 to July 2022. The article is a cross-sectional study. Clinical data, including age, gender, weight, defect diameter, tricuspid regurgitation, left atrial (LA) size, and the operation results, were collected and evaluated. Nonparametric rank sum tests were used to assess tricuspid regurgitation before and after surgery, while paired sample t-tests were used to compare LA size before and after surgery. RESULTS: TEE-guided percutaneous closure of ASD via the RIJV was successfully performed in 97 out of 103 (94.2%) cases. The average procedure time was 34.48±13.06 min, and the mean age at the time of the procedure and ASD size were 36±18 years and 15.45±5.82 mm, respectively. On analyzing medical records and echocardiographic images, postoperative complications were found to occur in four (3.9%) patients. Among these, three patients had residual shunt as indicated by echocardiography during the operation, which subsequently disappeared at the three-month follow-up. One patient developed atrial fibrillation after surgery but returned to normal sinus rhythm with medication. Percutaneous closure of ASD via the RIJV was unsuccessful in 6 patients (5.8%), with 5 of them undergoing transthoracic ASD closure and achieving satisfactory results. One patient refused further surgical treatment. No pericardial effusion, thrombosis, atrioventricular block, or other complications were observed during the 3-month to 1-year follow-up period. CONCLUSIONS: ASD closure via the RIJV is a safe and effective therapeutic approach. The initial results are satisfactory, but further studies with large sample sizes and long-term follow-up are warranted to assess the long-term outcomes.
