Introduction: Emphysematous endocarditis is caused by the gas-forming organisms , , species, and . We report the first case of emphysematous endocarditis caused by .
Case Report: An 82-year-old man presented with fever and rapidly progressive shortness of breath. He was found to be in atrial fibrillation with rapid ventricular rates. Two-dimensional transthoracic echocardiography demonstrated severe mitral regurgitation. Subsequent two- and three-dimensional transesophageal echocardiogram revealed a large, highly mobile vegetation on the atrial surface of the anterior mitral leaflet with aneurysmal destruction of the lateral scallop requiring mitral valve replacement. Sequencing of the vegetation revealed an anaerobic gram-positive coccus that, in rare cases, produces gas using a heme-dependent catalase. Histopathological analysis of the infected valve suggested interstitial gas accumulation, leading to the diagnosis of emphysematous endocarditis.
Conclusions: associated emphysematous endocarditis should be included in the differential diagnosis of valvular vegetation in patients with a rapidly progressing clinical course. When possible, histopathological analysis should be used alongside other imaging techniques to confirm the diagnosis of emphysematous endocarditis. This case also highlights the importance of collecting blood cultures prior to initiating antibiotic treatment.

Introduction And Importance: Infections of inferior vena cava (IVC) filters are rare. The authors present a case of IVC filter infection following concurrent emphysematous urinary tract infections that was finally treated with prolonged suppressive antibiotic therapy (PSAT).
Case Presentation: A 68-year-old man with pemphigoid and type 2 diabetes mellitus, who had undergone IVC filter placement, was transferred with decreased consciousness, respiratory failure, and hypotension.

Infective endocarditis (IE) is an infection of the heart endocardium with significant morbidity and mortality. Gram negative infection, particularly emphysematous IE, is an extremely rare and life-threatening disease. We report a 59-year-old diabetic female patient who was admitted to a secondary care hospital in Rustaq, Oman, in 2017 with the diagnosis of pneumonia for which she was started on antibiotics.

Diagnosis of myocardial abscess without endocarditis is challenging, and a high index of clinical suspicion is fundamental for diagnosis. It should never be ruled out before TEE. And CT could be a helpful modality in case of emphysematous morphology.
