Imaging findings in cardiac tamponade with emphasis on CT

Area of Science:

• Cardiology
• Radiology
• Emergency Medicine

Background:

• Cardiac tamponade is a critical condition caused by pericardial fluid accumulation, leading to heart compression and hemodynamic compromise.
• Multiple etiologies exist, including trauma, inflammation, and neoplastic disease, all contributing to increased intrapericardial pressure.
• The resulting cardiogenic shock is characterized by reduced cardiac output, stroke volume, and blood pressure.

Purpose of the Study:

• To elucidate the role of computed tomography (CT) in diagnosing cardiac tamponade.
• To correlate clinical and pathophysiological features with specific CT findings.

Main Methods:

• Review of clinical presentations and pathophysiological mechanisms of cardiac tamponade.
• Analysis of characteristic computed tomography (CT) findings in patients with cardiac tamponade.

Main Results:

• CT findings include large pericardial effusion, vena cava distention, and contrast reflux into the azygos vein.
• Cardiac chamber compression, interventricular septum bowing, and other intrapericardial structural deformities are noted on CT.
• These imaging findings are crucial for confirming the clinical diagnosis.

Conclusions:

• Computed tomography (CT) is instrumental in assessing cardiac tamponade and guiding therapeutic interventions.
• Early and accurate diagnosis relies on integrating clinical, pathophysiological, and CT findings.
• Familiarity with CT hallmarks of cardiac tamponade improves diagnostic accuracy and patient outcomes.
