Summary

Tuberculosis (TB) rarely affects the heart. This case highlights myocardial TB as a potential cause of congestive heart failure, even in patients without typical TB symptoms.

Area of Science:

  • Cardiology
  • Infectious Diseases
  • Pathology

Background:

  • Tuberculosis (TB) is a global health concern, typically sparing the heart, skeletal muscle, thyroid, and pancreas.
  • Myocardial involvement in TB is exceptionally rare, challenging conventional understanding of the disease's organ tropism.

Observation:

  • A patient presented with symptoms mimicking congestive heart failure.
  • Diagnostic investigations and clinical course were meticulously documented.
  • A post-mortem cardiac biopsy confirmed tuberculosis of the myocardium.

Findings:

  • The case underscores the possibility of myocardial TB, a condition seldom recognized.
  • Literature review indicates limited documented instances of TB affecting the heart muscle.

Implications:

  • Myocardial TB should be considered in the differential diagnosis of unexplained congestive heart failure, particularly in endemic TB regions.
  • Early diagnosis via endomyocardial biopsy can lead to treatment and potentially cure this form of cardiomyopathy.
