Application of transesophageal echocardiography in min-invasive hybrid procedure for intracristal ventricular septal defects in children / 中华超声影像学杂志

ABSTRACT

Objective To evaluate the clinical outcome of transesophageal echocardiography(TEE) in guiding and monitoring min-invasive transthoracic hybrid procedure for intracristal ventricular septal defects (VSD) using eccentric occluders.Methods 13 patients with intacristal VSD successfully underwent the min-invasive hybrid procedure using eccentric occluders were analyzed retrospectively.They were all carefully examined by transthoracic echocardiography (TTE) preoperatively and were diagnosed as intracristal VSD.There were no obvious aortic valve prolapse and no severe regurgitation.The entire process was guided and monitored by TEE.The condition of VSD occlusion was assessed by immediate postoperative TEE.Results All cases were occluded successfully.The results of postoperative TEE showed that the occluder was coincided closely with the edge of VSD,no aortic valve regurgitation worsen.2 had tiny residual left-to-right shunt (＜1.5 mm),which disappeared 1 and 3 months respectively after operation.No occluder dislocated followed-up at 6 months to 2 years postoperatively,and no major complications occurred.Conclusions The min-invasive hybrid procedure for intracristal VSD using eccentric occluders guided and monitored by TEE is easy to manipulate,which is safe,less invasive,and has excellent early-term results.
