Diffuse Myocardial Calcifications Caused by Leptospirosis

Area of Science:

• Infectious Diseases
• Cardiology
• Radiology

Background:

• Severe leptospirosis is characterized by multiple organ failure.
• Cardiac involvement in leptospirosis is uncommon and poorly understood.
• Diffuse myocardial calcifications secondary to sepsis are infrequent and challenging to predict.

Observation:

• A 51-year-old male presented with sepsis, diagnosed as leptospirosis.
• The patient developed septic cardiomyopathy with diffuse left ventricular myocardial calcifications.
• Myocardial calcifications are often incidentally found via imaging (e.g., CT scan) and may progress gradually.

Findings:

• Leptospirosis can lead to significant cardiac complications, including myocardial calcifications.
• These calcifications can cause conduction disorders and arrhythmias, potentially leading to sudden death.
• Multimodality imaging is crucial for diagnosing such rare cardiac manifestations.

Implications:

• Highlights the need for a multidisciplinary approach in diagnosing and managing complex sepsis cases.
• Emphasizes the importance of early recognition and treatment of cardiac involvement in leptospirosis.
• Underscores the necessity of long-term cardiac monitoring, including left ventricular systolic function and arrhythmia surveillance.
