Aims: To investigate the value of transesophageal echocardiography (TEE) in perimembranous ventricular septal defect (PmVSD) closure via a left parasternal ultra-minimal trans intercostal incision in children.
Methods: From January 2015 to December 2020, 212 children with PmVSDs underwent device occlusion via an ultra-minimal trans intercostal incision. TEE was used throughout the perioperative period, including TEE assessment, TEE-guided localization of the puncture site, and TEE guidance. All patients were followed up using transthoracic echocardiography for more than 6 months.
Results: A total of 207 cases were successfully occluded, and the success rate was 97.64%. One hundred forty-five patients had a single orifice, and 62 patients had multiple orifices in the aneurysm of the membranous septum (AMS). During the operation, the surgeon readjusted the device or replaced it with a larger device in 17 cases. After the operation, 19 cases of a slight residual shunt, 13 cases of pericardial effusion, and 4 cases of pleural effusion were noted. All patients returned to normal during the 4-month follow-up period. Mild mitral regurgitation was present in one patient and remained the same during the follow-up period. No other complications were found.
Conclusions: Under TEE guidance, PmVSDs were closed successfully using a concentric occluder via an ultra-minimal trans intercostal incision. TEE, which was used to assess defects and postoperative effect, effectively guide PmVSDs closure, is of great value.
