Fungal endocarditis is a cardiac complication that has been increasing throughout the world. We present a case of infective endocarditis by Paecilomyces variotii in a male patient with a prosthetic mitral valve. Successful treatment consisted of administration of amphotericin B (total dose 3670 mg) and mitral valve replacement. Only six cases have been reported previously, with a 100% mortality rate.

Fungal endocarditis (FE) is a rare complication in immunocompromised patients which is difficult to diagnose and has been characterized by excessive mortality (> 50%) and morbidity, regardless of treatment. The lack of clinical trials due to the small number of cases contributes further to a poor outcome. In our two cases of aspergilllus endocarditis we reviewed the clinical features, echocardiographic findings, microbiologic data, treatment, and outcome of these 2 cases and provide a current characterization of the syndrome. In this paper we have demonstrated the diversity of presentation of a critical fungal infection in immunocompromised but non neutropenic paediatric patients. The prompt diagnosis and initiation of treatment is crucial for a favourable outcome along with the use of double antifungal treatment with liposomal amphotericin and voriconazole initially which could be later switched to oral voriconazole with a good tissue penetration. Histological samples as well as radiological evidence and echocardiograms should be reviewed by experienced clinicians in order to aid diagnosis and promptly initiate treatment for these patients in order to achieve a favourable outcome.

Infective endocarditis is the most common and dangerous form of endovascular infection. Fungal endocarditis especially of native valve is rare with Candida albicans being the causative organism in one-fourth of such cases. Diagnosis of such cases is further complicated if blood cultures are sterile, vegetations are not initially seen on echocardiogram and patient presents with non-specific symptoms. We hereby report a patient with native valve fungal endocarditis, treated successfully with voriconazole.

The authors report a rare case of fungal endocarditis caused by Histoplasma capsulatum in an immunocompetent woman with mitral valve prosthesis. The patient presented with chronic fever and embolic phenomenon. Transthoracic and transesophageal echocardiography revealed a mobile mass attached to mitral prosthetic valve and her blood cultures were negative for both bacteria and fungi. The diagnosis was made by presence of budding yeasts in the histopathological findings of the vegetation and recovery of H. capsulatum from tissue culture of the excised vegetation. The patient was improved after a 6-week course of amphotericin B. Fungal endocarditis caused by Histoplama capsulatum is rare but should be considered as a possible causative organism in culture-negative endocarditis. To our knowledge, this is the first case report of H. capsulatum endocarditis in Thailand.

Fungal endocarditis is rare in comparison with bacterial endocarditis and is associated with a poor prognosis. Despite the proven reliability of echocardiography, false negatives are not uncommon and may influence the therapeutic strategy, as some reports have supported the efficacy of antifungal treatment alone. We report on a case of bioprosthetic aortic valve Candida parapsilosis endocarditis without typical echocardiograhy findings, which we treated with both antifungal and surgical therapy.

In recent decades the incidence of Candida endocarditis has increased dramatically. Despite the application of surgery and antifungal therapy, Candida endocarditis remains a life-threatening infection with significant morbidity and mortality. We report a 37-year-old male drug abuser presenting with high fever, chest pain, loss of appetite and cardiac failure. His echocardiography revealed mobile large tricuspid valve vegetations. Fungal endocarditis was confirmed by culturing of the resected vegetation showing mixed growth of Candida albicans and Candida tropicalis, although three consecutive blood cultures were negative for Candida species. Phenotypic identification was reconfirmed by sequencing of the internal transcribed spacer (ITS rDNA) region. The patient was initially treated with intravenous fluconazole (6 mg kg(-1) per day), followed by 2 weeks of intravenous amphotericin B deoxycholate (1 mg kg(-1) per day). Although MICs were low for both drugs, the patient's antifungal therapy combined with valve replacement failed, and he died due to respiratory failure.

Fungal endocarditis (FE) is an uncommon disease with a high risk of morbidity and mortality. Here, we evaluated the different methods for diagnosing this infection. Cardiac valve, vegetation, and embolic materials obtained during surgery were examined for fungal infections by direct smear and culture. At least two blood samples were inoculated at the bedside into BACTEC medium. Galactomannan, mannan Ag enzyme-linked immunosorbent assay, and real-time polymerase chain reaction (PCR) assay were performed with serum samples. Of 25 patients with suspected infective endocarditis (IE), 8 were found to have proven FE according to the direct culture results. The etiologic agents were Aspergillus niger (three cases), A. flavus (two cases), A. fumigatus (one case), and Candida albicans (two cases). Blood culture was positive in only 1 case. The sensitivity, specificity, positive and negative predictive values, and positive and negative likelihood ratios of the results from the galactomannan test were 83.3%, 84.2%, 62.5%, 94.1%, 5.3, and 0.2; these same values, obtained from real-time PCR, were 87.5%, 94.4%, 87.5%, 94.4%, 15.6, and 0.14, respectively. Because mannan antigen was positive in samples from only one patient, we opted not to calculate the sensitivity. However, the specificity value in 23 cases without IE caused by Candida spp. was 100%. Based on our results, both the galactomannan test and real-time PCR can serve as reliable, noninvasive tests for the diagnosis of FE, compared with culture, which is considered to be the gold standard.

Fungal endocarditis is an extremely debilitating disease associated with high morbidity and mortality. Candida spp. are the most common isolated organisms in fungal endocarditis. It is most prevalent in patients who are immunosuppressed and intravenous drug users. Most patients present with constitutional symptoms, which are indistinguishable from bacterial endocarditis, hence a high index of suspicion is required for pursuing diagnosis. Diagnosis of fungal endocarditis can be very challenging: most of the time, blood cultures are negative or take a long time to yield growth. Fungal endocarditis mandates an aggressive treatment strategy. A medical and surgical combined approach is the cornerstone of therapy.

Fungal endocarditis is a rare and fatal condition. The Candida and Aspergillus species are the two most common etiologic fungi found responsible for fungal endocarditis. Fever and changing heart murmur are the most common clinical manifestations. Some patients may have a fever of unknown origin as the onset symptom. The diagnosis of fungal endocarditis is challenging, and diagnosis of prosthetic valve fungal endocarditis is extremely difficult. The optimum antifungal therapy still remains debatable. Treating Candida endocarditis can be difficult because the Candida species can form biofilms on native and prosthetic heart valves. Combined treatment appears superior to monotherapy. Combination of antifungal therapy and surgical debridement might bring about better prognosis.

Fungal endocarditis is a rare entity which has a poor outcome. Our case reports an atypical presentation of similar pathology now presenting with femoral artery ischemia in an immune competent individual. A 62-year Asian male presented with sudden onset of right sided lumbar pain. Initial clinical exam was consistent with right sided renal colic. Intravenous analgesia did not relieve the pain. Repeat clinical examination revealed absent right femoral artery pulsation. The patient underwent a Computerized tomography angiography of right lower extremity. Echocardiogram revealed valvular vegetations that were later revealed to be because of Aspergillus Terreus. This case highlights the atypical presentation of a rare fungal endocarditis in an immune competent individual presenting with right sided lumbar pain. This case is of particular interest for emergency physicians who are at the forefront and may require to deal with such presentations.
