Thrombus in transit after balloon atrial septostomy

Area of Science:

• Cardiology
• Interventional Cardiology
• Pediatric Cardiology

Background:

• Balloon atrial septostomy (BAS) is a critical palliative procedure for congenital heart defects.
• Complications following BAS are uncommon, with most patients experiencing positive outcomes.

Purpose of the Study:

• To report a rare and previously undocumented complication of balloon atrial septostomy (BAS).
• To highlight the potential for a thrombus in transit as a cause of deterioration post-BAS.

Main Methods:

• Case report detailing a patient who experienced deterioration after a successful BAS.
• Review of clinical presentation, diagnostic findings, and management of the identified complication.

Main Results:

• The patient developed an unusual complication attributed to a thrombus in transit.
• This specific complication has not been previously reported in the literature following BAS.

Conclusions:

• A thrombus in transit is a potential, albeit rare, cause of deterioration after balloon atrial septostomy.
• Awareness of this complication is crucial for timely diagnosis and management in patients post-BAS.
