Summary
A woman experienced sudden loss of consciousness due to cardiac tamponade from a left ventricular rupture. Emergency drainage and surgical repair were successful, revealing underlying coronary artery disease.
Area of Science:
- Cardiology
- Cardiac Surgery
- Emergency Medicine
Background:
- Sudden loss of consciousness and pulseless electrical activity indicate a critical cardiovascular event.
- Massive pericardial effusion can lead to cardiac tamponade, impairing heart function.
Observation:
- An 83-year-old female presented with sudden syncope and unrecordable blood pressure.
- Electrocardiogram showed pulseless electrical activity; echocardiography revealed massive pericardial effusion.
Findings:
- Emergency subxiphoid pericardiotomy successfully released cardiac tamponade.
- Intraoperative exploration identified and repaired a ruptured posterior-lateral left ventricular wall defect.
Implications:
- Prompt diagnosis and bedside intervention are crucial for managing cardiac tamponade.
- Left ventricular rupture, though rare, can be surgically repaired.
- Postoperative cardiac catheterization identified significant coronary artery disease, a common comorbidity.
