Abstract:
PurposeTo explore the value of transesophageal echocardiography (TEE) monitoring mini-incision transthoracic occlusion of ventricular septal defect (VSD) with asymmetric ventricular defects occlude in preoperative selection of patients, intraoperative guidance monitoring and postoperative evaluation.Materials and MethodsForty-five cases of VSD undertook mini-incision transthoracic occlusion with asymmetric ventricular defects occlude were enrolled, their clinical data was analyzed retrospectively, preoperative transthoracic echocardiography (TTE) was applied for choosing appropriate cases. During surgery, TEE was employed for evaluating the VSD and in which perimembranous VSD was found in 21 cases, intracristal VSD in 15 cases and subpulmonic VSD in 9 cases, suitable eccentric type occluders were chosen, guide occluder was placed, and the occlusion effect was evaluated right after operation.ResultsThe procedures were completed successfully in 42 cases, with a successful rate of 93.3%, of which 21 cases had perimembranous VSD, 15 cases had intracristal VSD, and 6 cases had subpulmonic VSD. The diameter of the VSD ranged from 3 to 7 mm, averaging (4.5±0.7) mm, the diameter of occluders ranged from 4 to 8 mm, averaging (5.7±1.2) mm, there was a good positive correlation between size of VSD and occlude (r=0.87,P<0.05). All patients received follow-ups from 3 months to 24 months after operation, all the occluders located normally, with no more than mildly residual shunt, valve regurgitation or severe arrhythmia discovered.ConclusionMini-incision transthoracic occlusion of ventricular septal defect (VSD) with asymmetric ventricular defects occlude has high success rates, minimal injury, and lower complication rate. TEE can play a vital role by improving the success rate and safety of surgery.
