We report the case of a 46-year-old patient with a history of multifocal tuberculosis (peritoneal and pericardial) treated with anti-tuberculosis drugs and corticosteroid therapy for 12 months. He presented with progressive onset right heart failure syndrome during the course of his treatment related to chronic constrictive pericarditis documented by transthoracic ultrasound and right heart catheterization. The treatment was surgical by decortication with favorable operative consequences. This observation aims to question the rapid evolution of tuberculous pericarditis to chronic constrictive pericarditis usually described in the literature as a rare complication and occurring very late after several years.
