“…The involvement of listeriosis with AV block is yet to fully characterized in medical literature. During our review of published literature, we found only two case reports that reported AV block associated with listeriosis [16,17]. In the case report by Uehara et al [17], the patient was found to have a pseudotumor made up of L. monocytogenes .…”

“…Other investigators have reported the involvement of L. monocytogenes in endocarditis, prosthetic valve endocarditis, fetal pericarditis, myocarditis and myocardial infarction [1,3]. Pseudotumor of the heart and pseudotumoral right atrial involvement in L. monocytogenes septicemia has also been reported in the literature [17]. Yet, there remains a paucity of research characterizing atrioventricular (AV) block and its relationships with listeriosis in literature.…”

Listeria endocarditis is a rare, but serious disease with high mortality rate. Currently, little is known regarding the optimal treatment modality of Listeria endocarditis in affected individuals. Here, we present the case of a 66-year-old female with history of mitral and aortic replacement with bioprosthetic valve, and hospital course complicated by Listeria monocytogenes infective endocarditis with atrial-ventricular (AV) block. Listeria monocytogenes infection was eradicated by a 6-week antimicrobials course involving ampicillin and gentamicin, culminating in the resolution of AV block. On further investigation, the patient admitted to frequent consumption of salami and provolone cold-cut sandwiches, which based on previous evidence in literature is hypothesized to be the source of infection. Our findings suggest the development of perivalvular abscesses as the cause of the AV block. To our knowledge, this is the first reported case in literature where AV block secondary to listeriosis resolved with treatment solely by antimicrobials. While further research and larger studies are needed to extend our findings, patients with AV block secondary to listeriosis may benefit from optimized management with antimicrobials.

“…There are two reports of large right atrial masses consistent with tuberculomas on biopsy that completely resolved following 6 - 12 months of anti-tuberculous therapy [35, 36]. In addition, IP has also been reported in association with other infections including Listeria monocytogenes [37, 38] and Mycobacterium avium-intracellulare [39]. Primary cardiac tumors are often suspected by their appearance on imaging studies and the primary source of metastatic disease to the heart is usually obvious on review of history, examination, and laboratory testing.…”

Systemic rheumatologic and inflammatory disorders can affect almost any organ system, including the heart. The cardiac valves, conduction system, myocardium, endocardium, pericardium, and coronary arteries may be affected. Intracardiac masses may develop as part of the disease process or a consequence of their therapy, such as methotrexate-associated nodulosis. Optimal therapy in these cases is not known, since many patients are asymptomatic and the potential benefit of surgical excision must be weighed against its associated morbidity and mortality. Importantly, these inflammatory masses must be differentiated from thrombus, infection, and primary and metastatic tumors. We present three cases of inflammatory cardiac masses associated with rheumatoid arthritis and Wegener’s granulomatosis, which were successfully treated conservatively, and propose a management algorithm. The benefits of such an approach must be individualized and weighed against the risks of systemic embolization, stroke and obstruction.

“…About 60 % of listerial endocarditis is associated with valve dysfunction [ 3, 4 ], and patients with a prosthetic valve have a higher mortality rate than those with a native valve (41 and 31 %, respectively) [ 2, 3 ]. So far, approximately 80 cases of endocarditis due to Listeria monocytogenes have been reported in the literature [ 5 ]. Recurrent infection by Listeria monocytogenes occurs even more rarely.…”

Molecular evidence of Listeria monocytogenes infection relapse in a severe case of endocarditis

et al. 2017

View full text Add to dashboard Cite

Introduction. Endocarditis is a rare complication of bacteraemia due to Listeria monocytogenes and is characterized by a high fatality rate (37–50 %). Recurrent infection by Listeria monocytogenes occurs even more rarely.Case presentation. We report a case of recurrent Listeria monocytogenes infection that resulted in severe endocarditis in a 66-year-old patient with an aortic valve prosthesis. Relapse was confirmed by pulsed-field gel electrophoresis (PFGE) and multi-locus sequence typing (MLST).Conclusion. Our case highlights that the molecular subtyping approach is an important tool for the detection of microbial reinfections and for the support of clinical diagnosis.
