Redo Minimally Invasive Right Atrial Mass Removal After Surgical Atrial Septal Defect Closure.

Atrial septal defects are among the most prevalent congenital anomalies necessitating surgical intervention. Thrombus formation is a recognized complication that is typically characterized by an embolic event following patch-based repair. However, thromboembolic complications following primary repair of atrial septal defects are exceedingly uncommon. Minimally invasive surgery is a suitable alternative to redo sternotomy. We present a 46-year-old man who was diagnosed with a right atrial mass eight years following the patch repair of an atrial septal defect and underwent a successful minimally invasive redo surgery.
