Abstract: This study investigated the clinical effect of transesophageal echocardiography (TEE)-guided interventional closure surgery for ventricular septal defect (VSD). 53 patients with simple perimembranous VSD were selected for retrospective analysis. Among them, 29 patients underwent VSD occlusion through TEE-guided retrograde intubation through the femoral artery (study group), and 24 patients underwent traditional radiotherapy, the arteriovenous channel was established to perform transcatheter VSD interventional closure surgery (traditional group). The operation time, size of occluder, perioperative and postoperative complications, and echocardiographic indexes of left ventricular function of patients before and after surgery were compared between the two groups. The results showed that there was no significant difference in the size of the occluder between the research group and the traditional group (P>0.05), and the operation time of the research group was shorter than that of the traditional group (P<0.05). At 3 and 6 months after operation the measured values of Tie index, LVEDV, LVESV, peak E and peak A in the two groups were significantly lower than those before operation in the same group (P<0.05), and the measured values of LVEF were significantly higher than those in the same group. TEE-guided retrograde femoral artery intubation to complete VSD closure surgery is not much different from that of establishing arteriovenous passages under traditional radiation to implement transcatheter VSD interventional closure surgery, but the former simplifies surgical procedures and reduces X-ray damage.
