Pseudoaneurysm is a rare yet potentially life-threatening condition,typically arising as a complication of myocardial infarction,cardiac surgery,trauma,or infection.The incidence of postoperative pseudoaneurysms in congenital heart disease patients is exceedingly low.Traditional surgical intervention involves excising the pseudoaneurysm and repairing its base;however,this approach entails significant surgical trauma and elevated risk.This case report details the diagnosis of a left ventricular pseudoaneurysm(LVPA)in a 6-month-and-10-day-old child following corrective surgery for congenital heart disease.At 7 weeks of age,the patient underwent repair for ventricular septal defect,atrial septal defect,and pulmonary valve dilation.A LVPA was identified three months postoperatively.Four months after the initial procedure,successful percutaneous closure of the pseudoaneurysm was achieved via transfemoral access under transthoracic echocardiographic guidance.Postoperative follow-up confirmed optimal positioning of the occluder and satisfactory recovery in the child.This case underscores the efficacy and minimal invasiveness associated with ultrasound-guided percutaneous closure for newly developed LVPA in pediatric patients.
