Unrecognized tamponade diagnosed pre-induction by focused echocardiography

Area of Science:

• Cardiology
• Anesthesiology
• Critical Care Medicine

Background:

• A 58-year-old male with severe asymptomatic aortic stenosis presented for elective sinus surgery.
• Pre-operative cardiac evaluation deemed aortic valve replacement unnecessary due to asymptomatic status.

Observation:

• Focused transthoracic echocardiography (TTE) was performed pre-induction to establish baseline cardiac parameters.
• Unexpectedly, TTE revealed undiagnosed cardiac tamponade, necessitating urgent intervention.
• The patient was subsequently diagnosed with Churg-Strauss syndrome and treated with prednisone.

Findings:

• Focused perioperative TTE is valuable for diagnosing emergent cardiac conditions in complex patients.
• Echocardiographic findings significantly influenced immediate patient management, averting potential intraoperative complications.
• Anesthetic management considerations for Churg-Strauss syndrome were also addressed.

Implications:

• Focused TTE provides critical diagnostic and assessment capabilities for hemodynamically significant cardiac conditions.
• This technique is particularly useful in challenging clinical scenarios where physical examination may be limited.
• Early echocardiographic diagnosis can lead to prompt management decisions and improved patient outcomes.
