Transcatheter intervention for bilateral patent ductus arteriosus with isolated left brachiocephalic artery

Area of Science:

• Cardiovascular Medicine
• Pediatric Cardiology
• Interventional Cardiology

Background:

• Isolated left brachiocephalic artery is a rare congenital anomaly.
• Patent ductus arteriosus (PDA) can lead to significant hemodynamic alterations.
• Combined presence of these conditions may result in severe complications like excessive pulmonary blood flow and cerebral hypoperfusion.

Purpose of the Study:

• To describe a case of isolated left brachiocephalic artery with bilateral patent ductus arteriosus.
• To highlight the potential complications associated with this rare combination.
• To present the successful management of this complex case using transcatheter closure.

Main Methods:

• Case report detailing a patient with isolated left brachiocephalic artery and bilateral PDA.
• Review of relevant literature on similar anatomical variations and hemodynamic consequences.
• Description of the transcatheter closure procedure for both patent ductus arteriosus.

Main Results:

• The patient presented with symptoms suggestive of excessive pulmonary blood flow and potential cerebral steal phenomenon.
• Successful transcatheter closure of both patent ductus arteriosus was achieved.
• Post-procedural evaluation indicated resolution of hemodynamic abnormalities and improved cerebral perfusion.

Conclusions:

• Transcatheter closure is a viable and effective treatment option for bilateral patent ductus arteriosus in the setting of isolated left brachiocephalic artery.
• Early diagnosis and intervention are crucial to prevent severe complications such as cerebral atrophy.
• This case underscores the importance of recognizing and managing complex congenital cardiovascular anomalies.
