Peratrial device closure of perimembranous ventricular septal defects via a small right subaxillary incision: Midterm results in patients12 months of age
Both percutaneous and perventricular device closures of perimembranous ventricular septal defects (Pm-VSDs) are alternatives to surgical procedures，but they all present certain drawbacks.To report our clinical experiences and midterm follow-up results of minimally invasive peratrial device closure of Pm-VSDs under the guidance of transesophageal echocardiography(TEE) in patients12 months of age.Between January 2015 and December 2020，268 patients12 months of age with Pm-VSDs underwent peratrial device closure in our institute. The procedure was performed under TEE guidance via a small right subaxillary incision. The delivery pathways is established by manipulating the hollow probe, and then the device is installed.A total of 263 cases (98.1%) underwent successful closure, whereas five cases failed and were converted to cardiopulmonary bypass operation via the original incision during the procedure. The mean age was 9.5 ± 2.0 months and the mean body weight was 8.8 ± 1.4 kg. The mean diameter of the VSD was 4.4 ± 0.5 mm. One patient (0.4%) underwent a second thoracotomy for postoperative intercostal hemorrhage on the second day after surgery. The mean diameter of the occluder size was 5.5 ± 0.6 mm. During the follow-up (4.3 ± 1.4 y), there was no mortality, no new aortic valve regurgitation and atrioventricular block.Peratrial device closure of Pm-VSDs via the right subaxillary route under TEE guidance is safe and effective at midterm follow-up, confirming this is an valuable alternative method for patients12 months of age.
