Chiari network diagnosis intraoperative based on echocardiography

Area of Science:

• Cardiology
• Cardiac Surgery
• Congenital Heart Abnormalities

Background:

• Intraoperative hemodynamic instability can arise from various causes, including undiagnosed congenital cardiac anomalies.
• The Chiari network is a rare remnant of fetal circulation, typically asymptomatic.

Observation:

• A case of intraoperative supraventricular tachycardia (SVT) with significant hemodynamic compromise was observed.
• Diagnostic workup during surgery focused on identifying cardiac abnormalities, specifically congenital remnants.

Findings:

• The Chiari network was identified as the likely cause of the intraoperative SVT and potential cardiac flow obstruction.
• This congenital remnant was differentiated from more common causes of intraoperative hemodynamic alterations.

Implications:

• Recognizing the Chiari network as a potential cause of intraoperative SVT is crucial for surgical management.
• This case highlights the importance of considering rare congenital anomalies in the differential diagnosis of intraoperative complications.
