Beating pulmonary vein sign during catheter ablation

Area of Science:

• Cardiology
• Medical Imaging
• Physiology

Background:

• Cardiac tamponade is a life-threatening condition where fluid accumulation in the pericardium compresses the heart.
• Early detection of cardiac tamponade is crucial for timely intervention and preventing adverse outcomes.
• Pulmonary veins are critical vessels returning oxygenated blood to the heart's left atrium.

Purpose of the Study:

• To describe the phenomenon of a beating pulmonary vein during cardiac catheterization.
• To highlight the diagnostic utility of the beating pulmonary vein sign in identifying cardiac tamponade.
• To emphasize the importance of this sign for early diagnosis and management of cardiac tamponade.

Main Methods:

• Observational case report during cardiac catheterization procedures.
• Identification of the "beating pulmonary vein" sign based on characteristic movements.
• Correlation of the sign with the presence and severity of pericardial effusion and cardiac tamponade.

Main Results:

• The beating pulmonary vein sign was observed in a specific clinical context of cardiac tamponade.
• This sign is a direct consequence of the heart's mechanical action through pericardial effusion.
• The presence of the beating pulmonary vein sign indicates significant cardiac compression.

Conclusions:

• The beating pulmonary vein is a rare but significant indicator of cardiac tamponade during cardiac catheterization.
• This sign offers a valuable, potentially pre-collapse, diagnostic clue for clinicians.
• Prompt recognition of the beating pulmonary vein sign can facilitate urgent management of cardiac tamponade.
