Key result
H1N1 influenza A infection can lead to severe pericarditis and life-threatening cardiac tamponade even in previously healthy young adults.
Case Report (n=1)
H1N1 influenza A infection can rarely lead to severe pericarditis and cardiac tamponade, which can be successfully managed with urgent pericardiocentesis and medical therapy.
H1N1 pericarditis may cause tamponade even without prior heart disease; this Level 5 case leaves open its true incidence and management implications.
INTRODUCTION: The cardiac manifestations of influenza A are broad, ranging from self-limited pericarditis to fatal cardiomyopathy. The 2009 H1N1 influenza A (H1N1) strain is a rare cause of pericarditis, and its role in developing a pericardial effusion leading to tamponade has infrequently been reported. CASE PRESENTATION: We describe a case of a young female with no prior cardiovascular history who presents with a pericardial effusion and shock secondary to cardiac tamponade from pericarditis due to H1N1 influenza A. CONCLUSIONS: This case highlights the potential severity of H1N1 infections and the utility of considering cardiac tamponade in patients presenting with influenza symptoms and circulatory collapse.

Bainey et al. (2015) conducted a case report in Cardiac tamponade secondary to H1N1 influenza A (n=1). H1N1 influenza A infection was evaluated on Clinical outcome of cardiac tamponade. H1N1 influenza A infection can lead to severe pericarditis and life-threatening cardiac tamponade even in previously healthy young adults.
