Hypothesis-generating for giant right atrium in rheumatic disease; leaves open optimal long-term management strategies.
Giant right atrium (RA) is a rare finding in adults. We report a case of a 53-year-old female with rheumatic heart disease (RHD) previously submitted to two mitral valve replacements. She presented at the emergency room with signs of heart failure. Image studies revealed gross cardiomegaly. Transthoracic echocardiogram showed torrential tricuspid regurgitation, with right chambers enlargement. At chest tomography, the estimated right atrium volume was 1,200 mL. The patient was treated with intravenous diuretics and multiple paracentesis, as well as referred to heart transplantation. Physicians should be aware of this extreme outcome, which can lead to life-threatening complications such as atrial fibrillation and thromboembolism.

Voltarelli et al. (2023) conducted a case report in Rheumatic heart disease with giant right atrium (n=1). Diuretics and paracentesis was evaluated. A 53-year-old female with rheumatic heart disease developed a giant right atrium of 1,200 mL due to severe tricuspid regurgitation, requiring management with diuretics and paracentesis.
