Cardiac Tamponade in a Patient With Myocardial Infarction and COVID-19: Electron Microscopy

Area of Science:

• Cardiology
• Infectious Diseases
• Pathology

Background:

• Myocardial infarction and COVID-19 are serious conditions.
• Hemorrhagic pericardial effusion and cardiac tamponade are rare but critical complications.

Purpose of the Study:

• To present a unique case of myocardial infarction and COVID-19 leading to cardiac tamponade.
• To discuss the differential diagnosis and diagnostic methods for this rare presentation.

Main Methods:

• Case report of a patient with co-existing myocardial infarction and COVID-19.
• Differential diagnosis considered: post-infarction pericarditis, mechanical complications, thrombolysis, Dressler syndrome, viral pericarditis.
• Histopathologic and electron microscopic examination of pericardial tissue for definitive diagnosis.

Main Results:

• The patient developed hemorrhagic pericardial effusion and cardiac tamponade.
• Histopathology and electron microscopy confirmed the diagnosis.

Conclusions:

• This case highlights a rare but severe complication of myocardial infarction in the context of COVID-19.
• Accurate diagnosis requires thorough differential consideration and advanced examination techniques.
