Background: Transthoracic intervention for isolated congenital heart disease (CHD) has been well tested for its technological feasibility and is increasingly used in clinical practice. We aimed to present our experience in simultaneous transthoracic intervention for multiple cardiac lesions in a series of pediatric patients.
Methods: Between March 2015 and December 2019, 20 patients with multiple CHD were referred to this study; mean age was 18.8±8.6 (range, 4-36) months. The transthoracic echocardiography (TTE) diagnosis was atrial septal defect (ASD) and perimembranous ventricular septal defect (pmVSD) in 7 patients, patent ductus arteriosus (PDA) and ASD in 6, pmVSD and PDA in 2, pmVSD and valvular pulmonary stenosis (PS) in 2, ASD and PS in 2, and doubly committed subarterial VSD (dcsVSD) and PS in 1 patient. These patients underwent simultaneous transthoracic interventions with transesophageal echocardiography guidance. The procedure sequence was PS→VSD→PDA→ASD. Electrocardiography and TTE were scheduled at discharge and follow-ups.
Results: All patients were occluded successfully without any thoracotomy conversion. Operation time was 56-120 (mean, 75±13) minutes. A 1.5-2.0-cm median sternum incision was performed in 6 ASD&PDAs, 2 ASD&PSs, and 1 dcsVSD&PS. In 11 other patients, a 1.5-2.0-cm incision in the inferior sternum was made and the chest closed with a drain. There were no serious complications before discharge and at follow-up.
Conclusions: Simultaneous transthoracic intervention for multiple cardiac defects in children is feasible with good short-term outcomes. For different lesions, the appropriate surgical incision and operational sequence can render the intervention minimally invasive and safer.
