A 59-year-old man presented with exertional dyspnoea and pretibial oedema that had lasted 6 months. He was referred to our hospital with suspected constrictive pericarditis (CP). Several examinations, including CT, echocardiography and cardiac catheterisation, indicated heart failure associated with CP that had been induced by trauma 13 years prior. The CP and heart failure were unresponsive to medical treatment, therefore, a surgical pericardiectomy was performed, which is considered the only definitive treatment. Pathological examination of the resected pericardium revealed a fatty texture and dense fibrous connective tissues, which are associated with old haemorrhage and focal calcification. The patient’s symptoms were improved to New York Heart Association Class I, and his peripheral oedema disappeared 6 months after leaving hospital.
A 61-year-old woman who underwent hemodialysis presented with heart failure. Echocardiography revealed multiple mobile masses in the left atrium. The masses were excised, and histopathologic examination revealed calcified amorphous tumors. Here, we present several echocardiography images, including 3-dimensional transesophageal echocardiography, demonstrating the revolving masses in the left atrium.

Urinary tract infection (UTI) is one of the adverse effects of sodium-glucose cotransporter 2 (SGLT2) inhibitors. We describe a rare case of septic shock due to UTI in an immunosuppressed patient prescribed dapagliflozin. A 69-year-old woman was admitted to our hospital for the treatment of pyelonephritis. She was prescribed immunosuppressive drugs for systemic lupus erythematosus and was newly prescribed dapagliflozin for heart failure two weeks prior. One hour after admission, the patient developed hypotension and was diagnosed with septic shock due to UTI. She was administered norepinephrine, hydrocortisone and meropenem. Afterward, she underwent emergent transurethral lithotomy for her right urinary tract stones. The following clinical course was uneventful, and she was discharged on day 17. She had no recurrence of UTI or exacerbation of heart failure without dapagliflozin administration. This case report emphasizes the importance of considering the possibility of UTIs and cases in which SGLT2 inhibitors should be used. If a patient is female and immunocompromised, dapagliflozin should be prescribed more carefully after considering the increased risk of UTIs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
