Right ventricular outflow tract obstruction produced by a myocardial abscess in a patient with tuberculosis

Tuberculous dilated cardiomyopathy: an under-recognized entity?

“…Rhythm disturbances include supraventricular arrhythmias [3,6], ventricular arrhythmias [9] or varying degrees of conduction blocks [10], and sudden cardiac death is also described [5,11]. Right ventricular outflow tract obstruction [3,12,13], ventricular aneurysm [4,13], ventricular pseudoaneurysm [14], aortic insufficiency [15], coronary arteritis [10,13], or congestive heart failure [6,16,17] have also been described in literature. Recently, magnetic resonance imaging has also been used in the diagnosis of myocardial TB [18].…”

“…Antitubercular drugs are the cornerstone of therapy [6], and surgery [12,14-16] is indicated only in complicated cases. Paradoxically, our patient presented with features of congestive heart failure, and echocardiography showed severe left ventricular systolic dysfunction inspite of being on anti-tuberculous therapy which had resulted in bacteriological improvement of the pulmonary lesions.…”

Isolated right atrium tuberculoma causing complete heart block

“…The reported presentations include complete heart block,5 7 aortic regurgitation,8 left ventricular aneurysm and pseudoaneurysm,9 10 superior vena cava syndrome11 and right ventricular outflow tract obstruction 12. Our case appears to be the first one reported of complete atrioventricular block with right atrium tuberculoma.…”

Diagnostic challenges in a patient with myocardial tuberculoma: A case report

“…The most common cardiac symptoms are arrhythmias both ventricular and as in this patient episodes of supraventricular arrhythmia [8], [9]. Due to the localization of the tuberculoma, intermittent or permanent obstruction within the chambers may affect hemodynamics [10]. Another complication can occur if necrotic tissue separates from the tuberculoma margins, causing septic embolism [11].…”
