A rare case of tuberculous myocarditis: A diagnostic challenge in a tuberculosis‐endemic country

Abstract

Key Clinical MessageTuberculous myocarditis is a rare presentation of tuberculosis, posing diagnostic challenges in endemic countries. Clinicians should consider this entity in patients with unexplained heart failure, conduction abnormalities, or sudden cardiac events in tuberculosis‐endemic regions.AbstractTuberculous myocarditis is an uncommon manifestation of tuberculosis, often presenting as a diagnostic challenge, particularly in tuberculosis‐endemic regions. We report a case of a 58‐year‐old male with a history of chronic cough and fever, who presented with progressive dyspnea, generalized body swelling, and New York Heart Association (NYHA) Class IV heart failure. Clinical examination revealed signs of cardiac decompensation and congestive heart failure. Emergency echocardiography demonstrated biventricular dysfunction, and imaging showed clots in both atria and the left ventricle. The patient responded well to initial treatment with anticoagulants, antibiotics, diuretics, and inotropic support. Subsequent investigations, including computed tomography pulmonary angiogram (CTPA) and high‐resolution computed tomography (HRCT), confirmed active pulmonary tuberculosis. Anti‐tuberculous treatment (ATT) was initiated, and the patient showed remarkable improvement. The diagnosis of tuberculous myocarditis was based on clinical, radiological, and laboratory evidence, as cardiac biopsy was not performed due to resource limitations. Tuberculous myocarditis is an underreported condition, and clinicians should be vigilant about its occurrence, especially in tuberculosis‐endemic regions. Early recognition and prompt initiation of ATT can lead to favorable outcomes. This case highlights the importance of considering tuberculous myocarditis in patients with unexplained heart failure or cardiac abnormalities in areas with a high burden of tuberculosis.

“…TB primarily affects the lungs through the airborne transmission of bacteria when infected individuals cough, sneeze, or spit [ 4 , 5 , 6 , 7 ]. Upon entering the bloodstream, the bacteria can attack other organs and tissues, including the brain, kidneys, bones, spine, skin, peripheral lymph nodes, heart, pancreas, thyroid, spleen, eye, and skeletal muscles [ 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 ].…”
