Staphylococcus aureus is one of the most common causative pathogens of bloodstream infections (BSIs). In approximately one-half of patients with S. aureus BSI, no portal of entry can be documented. This group of patients has a high risk of developing septic metastases. Similarly, patient populations at high risk of S. aureus BSI and BSI-associated complications include patients receiving hemodialysis, injection drug users, patients with diabetes, and patients with preexisting cardiac conditions or other comorbidities. One of the most severe complications of S. aureus BSI is infective endocarditis, and S. aureus is now the most common cause of infective endocarditis in the developed world. Patients with methicillin-resistant S. aureus BSI or infective endocarditis have higher rates of mortality, compared with patients with methicillin-susceptible S. aureus infection. Nasal carriage is the most important source of S. aureus BSI. Better eradication and control strategies, including nasal decolonization and more-active antibiotics, are needed to combat S. aureus BSIs.

A 58-year-old female presented with symptoms mimicking infective endocarditis and was diagnosed with a right ventricular metastasis from a transitional cell carcinoma (TCC) of the left renal pelvis. The patient was treated with concurrent removal of the cardiac tumour and radical left nephrectomy followed by adjuvant gemcitabine-cisplatin chemotherapy. To our knowledge, this is the 14th report of cardiac metastases from TCC and the only case where one-stage surgical management of primary and cardiac metastases from TCC has been successfully completed.

Mural vegetations in the course of infective endocarditis are very rare. We report the case of a patient with an extremely large right ventricular free wall vegetation. Establishing diagnosis in the presence of only mural vegetations on echocardiography scan without valve involvement in the inflammatory process was difficult. In a differential diagnosis, benign and malignant tumours, metastases and thrombi were taken into account. The patient was operated upon and the tumour was removed successfully. A histopathological examination revealed an inflammatory character of the tumour. The patient was treated according to antibiogram and discharged home in stable condition.

Primary aortic graft infection early after aortic graft insertion is well described in the literature. Here, we present a unique case of late aortic graft infection 5 years after insertion secondary to mitral valve endocarditis, resulting from cellulitis in a patient with severe venous varicosities. A 63-year-old male presented for severe low back pain, constipation, and low-grade fever. An abdominal computed tomography scan with oral and intravenous contrast showed a normal spine and urinary tract. Blood and urine cultures, done at the same time, grew Staphylococcus aureus. A transesophageal echocardiogram confirmed the diagnosis of endocarditis. Subsequently, a gallium scan showed increased uptake in the vertebral bodies, aortic graft, left patella, and left ankle. After 3 months of antibiotic therapy, the patient's low back pain resolved with normalization of his laboratory values. He remained free of infection at a 2-year follow-up. We reviewed the literature concerning the atypical presentation of infective endocarditis, with a focus on distant metastases at initial presentation, such as osteomyelitis and aortic graft infection, as well as the different treatment modalities. This report describes successful medical treatment with intravenous followed by oral antibiotics for an infected endovascular graft without any surgical intervention.

Secondary systemic vasculitis and nonbacterial endocarditis are rare events. We report a case presented with different manifestations of underlying malignancy such as systemic vasculitis, non bacterial endocarditis and DIC (disseminated intravascular coagulopathy). Efforts to find the source of malignancy was unsuccessful and due to patient's unwillingness for further evaluation, finally under the diagnosis of metastatic disease of unknown primary, patient is receiving cyclic chemotherapy.

We present a case of a middle-aged male patient who was admitted to our institution because of the supposed diagnosis of endocarditis/myocarditis. Echocardiographic findings revealed cystic mass in the left myocardial wall as well as floating structures at the lateral papillary muscle, mimicking endocarditis/myocarditis. Due to progressive urinary retention and clinical signs of a beginning ileus, an abdominal and thoracic computed tomographic scan was performed, which demonstrated a large diverticle of the urinary bladder with expansive tumorous wall mass. One week later, the patient died of acute cardiorespiratory failure. On autopsy, the tumorous mass in the urinary bladder with large carcinosis of the peritoneum and multiple left and right ventricular metastases were confirmed; the histological analysis indicated a less differentiated urothelial cell carcinoma with its origin in the large diverticle of the urinary bladder with subsequent cardiac metastases.

Clinical preference for a semisynthetic penicillin (oxacillin or nafcillin) over cefazolin for deep-seated methicillin-susceptible Staphylococcus aureus (MSSA) bloodstream infections (BSI) perseveres despite limited data to support this approach. A retrospective cohort study of patients treated for MSSA BSI with either oxacillin or cefazolin was performed across two medical centers in Chicago, IL. The outcome measures included documented in-hospital treatment failure, all-cause in-hospital mortality, duration of MSSA BSI, and incidence of documented adverse events. Of 161 patients with MSSA BSI, 103 (64%) received cefazolin, and 58 (36%) received oxacillin. The identified sources of BSI were central line (37.9%), osteoarticular (18%), and skin and soft tissue (17.4%). Patients with endocarditis (29/52 [44.2%]) and other deep-seated infections (23/52 [55.8%]) were classified under the subset of deep-seated infections (52/161 [32.3%]). Multivariate models found deep-seated infection (adjusted odds ratio [aOR], 4.52; 95% confidence interval [CI], 1.23 to 16.6; P = 0.023), metastatic disease (aOR, 4.21; 95% CI, 1.13 to 15.7; P = 0.033), and intensive care unit (ICU) onset of infection (aOR, 4.80; 95% CI, 1.26 to 18.4; P = 0.022) to be independent risk factors for in-hospital treatment failure. Treatment group was not an independent predictor of failure (aOR, 3.76; 95% CI, 0.98 to 14.4; P = 0.053). The rates of treatment failure were similar among cefazolin-treated (5/32 [15.6%]) and oxacillin-treated (4/20 [20.0%]) patients (P = 0.72) in the subset of deep-seated infections. Mortality was observed in 1 (1%) and 3 (5.2%) cases of cefazolin- and oxacillin-treated patients, respectively (P = 0.13). Cefazolin was not associated with higher rates of treatment failure and appears to be an effective alternative to oxacillin for treatment of deep-seated MSSA BSI.

We report a case of nonbacterial thrombotic endocarditis (NBTE) in a patient with bladder cancer presenting with multiple cerebral infarctions. Initial transthoracic and transesophageal echocardiography did not show any abnormalities. However, repeat transthoracic and transesophageal echocardiography demonstrated a vegetation on the anterior leaflet of the mitral valve with mild mitral regurgitation and no evidence of leaflet destruction. Persistent high-grade fevers and leukocytosis were observed. The patient was suspected to have infective endocarditis. However, abdominal ultrasound and computed tomography scan revealed multiple metastatic masses, and serial blood cultures were negative. The patient was ultimately diagnosed with NBTE associated with multiple metastases of bladder cancer. This case suggests that even if echocardiography does not initially demonstrate any abnormalities in patients with embolism, it must be repeated at the recurrence of embolism, and that even if clinical signs of infection are documented, NBTE should be suspected in any cancer patient with thromboembolic events.

Renal infarction is a rare cause of acute kidney injury which could lead to permanent loss of renal function. A prompt diagnosis is necessary in order to achieve a successful revascularization of the occluded artery. Given the rarity of the disease and the paucity of the reported cases in the previous literature a high index of suspicion must be maintained not only in the classical cardiac sources of systemic emboli (atrial fibrillation, dilated cardiomyopathy, or endocarditis), but also in the situations when a hypercoagulable state is presumed. The unspecific presenting symptoms often mask the true etiology of the patient's complaints. We present here a rare case of renal infarction that occurred in the setting of a hypercoagulable state, in a female patient with a history of breast cancer and documented hepatic metastases.

Marantic or nonbacterial thrombotic endocarditis is characterized for the presence of vegetations formed by a meshwork of fibrin and other cellular material similar a blood clot, without the presence of microorganisms. It is often related with tumors and chronic inflammatory states. We report a 49 years old female with a history of weight loss and asthenia, presenting with multiple cerebrovascular attacks and fever. Blood cultures were negative and the fever did not subside with antibiotic treatment. Trans esophageal echocardiogram showed a mitral valve vegetation and thickening of the free edge of both leaflets. In search of the etiology of such a case, a primary pancreatic cancer with distant metastases was found. We cannot rule out the differential diagnosis with bacterial endocarditis with negative blood cultures, although the clinical context supports a non-infectious etiology.
