Aorta-right atrial fistula after VSD operation

Area of Science:

• Cardiovascular Surgery
• Congenital Heart Disease
• Surgical Complications

Background:

• Ventricular septal defects (VSD) are common congenital heart abnormalities.
• Surgical repair of VSD is a standard procedure.
• Late complications after cardiac surgery can occur, necessitating long-term monitoring.

Observation:

• A previously unreported iatrogenic complication occurred 14 years after VSD closure.
• The complication manifested as an aorta-right atrium fistula.
• The fistula originated proximally and extended into the right atrium.

Findings:

• An aorta-right atrium fistula developed as a late sequela of VSD surgical repair.
• This represents a novel iatrogenic complication in cardiac surgery.
• Previous VSD operations are identified as a potential cause.

Implications:

• Recognition of this complication is crucial for timely diagnosis and management.
• Cardiac surgeons should consider prior VSD repair in patients presenting with aorta-right atrium fistulas.
• Surgical correction is necessary to address this serious complication.
