Exploration Research of Ventricular Septal Defect Closure via Trans-jugular Approach Solely Under the Guidance of Echocardiography / 中国循环杂志

ABSTRACT

Objective: In order to avoid the radiation and contrast agent injury, and to extend the echocardiography guided percutaneous ventricular septal defects (VSD) closure, based on femoral artery approach, we assessed the efifcacy and safety of VSD closure via trans-jugular approach solely under the guidance of echocardiography. Methods: A total of 12 patients with peri-membranous VSD treated in our hospital from 2014-10 to 2015-04 were enrolled. The patients were at the age at (1.2-3.5 with the mean of 2.4 ± 0.8 ) years, the body weight at (7-15 with the mean of 11.6 ± 2.6) kg and the diameter of VSD was (3.5-6 with the mean of 4.8 ± 0.7) mm. The patients received percutaneous VSD closure via transjugular approach solely under the guidance of echocardiography. The procedural effect was evaluated by echocardiography and the follow-up study was conducted at 1, 3 and 6 month safter the procedures. Results: There were 9 patients successfully ifnished VSD closure via trans-jugular approach. 1 patient was converted to femoral artery approach because the wire could not pass through the defect of ventricular septal; 1 was converted to minimally invasive per-ventricular closure since the catheter could not pass through the defect; 1 was converted to conventional surgical repair due to the residual shunt was more than 2mm. The procedural time was (53-89 with the mean of 67.2±12.5) min, the diameter of symmetrical occluder was (6-8 with the mean of 7.0±0.9) mm. 2 patients had immediate post-operative residual shunt, all patients were recovered and discharged. No peripheral vascular injury and cardiac perforation occurred, the hospitalization time was (3-5 with the mean of 3.6 ± 0.7) days. The follow-up examination was conducted at (1-6 with the mean of 3.9 ± 2.1) months, the slight residual shunt in 2 patients disappeared at 1 month after procedure; no pericardial effusion, occluder malposition, aortic regurgitation and atria-ventricular block occurred. Conclusion: Echocardiography guided trans-jugular approach of VSD closure is safe and effective, it may particularly avoid the radiation and contrast agent injury in clinical practice.
