Iatrogenic atrial septal defects caused by cardiac surgery are rare complications that are traditionally repaired through reoperations; unfortunately, reoperations are accompanied by high risk and trauma.Patient concerns:
Herein, we report a rare case of a huge atrial septal defect after mitral and aortic mechanical valve replacement.Diagnoses:
Transesophageal echocardiography revealed a 20 × 33 mm atrial septal defect with a mainly left-to-right shunt and bidirectional shunt.Interventions:
The defect was successfully occluded using a Shape Memory septal occlude with a waist diameter of 42 mm.Outcomes:
At follow-up 6 months after, the patient's symptoms were remarkably relieved and chest radiograph showed obvious improvement of the pulmonary congestion.Lessons:
Percutaneous device treatment can be used as an alternative to surgery in iatrogenic atrial septal defects if the anatomical condition of the septal defect is appropriate for transcatheter closure.
