Atrial Septal Defect Device Closure With Balloon Support in a Patient With Situs Inversus With Dextrocardia.

This case report describes a rare and complex case of atrial septal defect (ASD) device closure in a 53-year-old female patient with situs inversus and dextrocardia, who presented with exertional dyspnea and palpitations. The procedure posed unique challenges due to the patient's mirror-image anatomy, requiring meticulous pre-procedural planning and advanced imaging. During the intervention, we used balloon support and modified fluoroscopic and echocardiographic views to account for the reversed orientation, ensuring precise device placement. This case highlights the importance of individualized approaches in managing structural heart defects in patients with complex congenital anomalies and underscores the feasibility of ASD device closure in such challenging anatomical conditions, providing insights for similar interventions in the future.
