An adolescent with Behcet's aortitis mimicking infective endocarditis: a case report.

ABSTRACT:

Background

Aortic valve involvement is rare in patients with Behçet' s disease (BD); however, recurrent prosthetic valve detachment after valve surgery has frequently been reported. We report a rare case of Behçet's aortitis involving the aortic valve, mimicking active infective endocarditis (IE) with perivalvular abscess.

Case summary

A 16-year-old boy, with an unknown case of BD, presented with pyrexia of unknown origin, severe aortic valve regurgitation, vegetation, and perivalvular abscess in the aortic valve. All cultures tested negative for microorganisms. As we suspected IE, aortic valve replacement was performed. After the initial surgery, recurrent prosthetic valve detachment and pseudoaneurysm formation occurred, which resulted in the diagnosis of BD. The patient underwent a modified Bentall procedure, in which the valve conduit was proximally sutured to the left ventricular outflow tract instead of the aortic annulus. Immunosuppressive therapy was initiated on the 10th postoperative day. His condition became stable, and additional surgery was not required.

Discussion

The echocardiographic findings of Behçet's aortitis involving the aortic valve resemble those of aortic valve IE. Modified Bentall procedure, combined with effective immunosuppressive therapy, may be useful in preventing prosthetic valve detachment.

Rheumatoid arthritis mimicking infective endocarditis with severe aortic regurgitation and aortic root abscess: a case report.

Project description:BackgroundRheumatoid arthritis (RA) may involve the cardiovascular system and can cause significant structural cardiac disease. RA mimicking infective endocarditis (IE) is rarely reported.Case summaryA 46-year-old man with a medical history of seropositive RA attended a planned outpatient visit for infliximab treatment. The pre-infusion examination revealed a pulse of 41 b.p.m. and the following electrocardiogram showed 3rd degree atrioventricular block. A temporary pacemaker was inserted, and subsequent transthoracic and transoesophageal echocardiograms showed severe aortic valve regurgitation with thickened cusps and thus raised suspicion of infective aortic endocarditis with root abscess. The patient underwent surgery with valve and root replacement the next day. What was thought to be IE, proved to be suppurative and granulomatous inflammation with sporadic necrosis and hyaline fibrosis, compatible with a rheumatoid nodule linked to the patient's RA diagnosis.DiscussionIE is a disease with high mortality and morbidity. In some cases of IE perivalvular cavities develop, most commonly abscesses and/or pseudoaneurysms, which necessitates surgery. Several conditions may mimic IE: for example, malignant and benign tumours, rheumatic diseases, and common age-related valve calcification. In patients with valvular vegetations that are 'culture-negative', alternative pathologies should be considered.

Infective endocarditis complicating COVID-19 pneumonia: a case report.

Project description:BackgroundDuring the COVID-19 outbreak, cardiovascular imaging, especially transoesophageal echocardiography (TOE), may expose healthcare personnel to virus contamination and should be performed only if strictly necessary. On the other hand, transthoracic echocardiography (TTE) and TOE represent the first-line imaging exams for the diagnosis of infective endocarditis (IE). To date, this is the first case of COVID-19 complicated by IE.Case summaryWe present the case of a 57-year-old man with severe COVID-19 pneumonia requiring mechanical ventilation. During the intensive care unit (ICU) stay, he developed fever and positive haemocoltures for methicillin-resistant Staphylococcus aureus infection. TTE did not identify endocardial vegetations. TOE was then performed and outlined IE of the aortic valve on the non-coronary cusp. Antibiotic therapy was given with progressive resolution of the septic state and improvement of inflammatory signs. After 30 days of ICU stay, the patient was transferred to the Sub-ICU and then to a rehabilitation hospital. A close follow-up has been scheduled: after full recovery, a new echocardiography will be performed (TTE and TOE, if the former is non-conclusive) to consider surgical valve repair in the case of persistence/progression of the valvular lesion or deterioration of the valve function.DiscussionIn COVID-19 patients, echocardiography remains the leading imaging exam for the diagnosis of IE. If the suspicion of IE is high, even in this setting of patients, TTE or TOE (if TTE is non-conclusive) are mandatory. A high degree of attention must be paid and appropriate preventive measures taken to avoid contamination of healthcare personnel.

Surgicel mimicking early onset prosthetic valve endocarditis: case report.

Project description:BackgroundSurgicel is one of the commercial forms of oxidized regenerated cellulose used as a bioabsorbable topical haemostatic agent during surgical procedures. However, its presence can mimic an abscess, tumour, lymph node or retained foreign body on imaging studies. The challenge in cardiac surgery is to differentiate the haemostatic material from an abscess that might be mistaken for an early onset prosthetic valve endocarditis.Case summaryA 56-year-old woman was admitted to our department for a suspicion of early onset prosthetic valve endocarditis after an aortic valve replacement. An early clinical and biological improvement, features on a chest computed tomography scan, as well as a surgical correlation were able to rectify the diagnosis. The acute fever was linked to urinary tract infection, whereas the periaortic echogenic mass shown at the transoesophageal echocardiography corresponded to Surgicel.DiscussionOxidized regenerated cellulose can mimic an abscess on cardiac imaging, especially when used in excess during cardiac surgery. Fortunately, some radiographic features can help differentiate the haemostatic material from an abscess. Hence, sharing the use and location of Surgicel between the surgeon, radiologist, and cardiologist is very important and necessary to make the correct diagnosis.

Infective endocarditis presenting as diffuse alveolar hemorrhage: A case report.

Project description:An 80-year-old man was admitted to the hospital because of fever, bloody sputum and exertional dyspnea of 3 days. Laboratory tests showed anemia and increase of the C-reactive protein level. A chest computed tomography scan revealed diffuse bilateral ground-glass opacities. Bronchoalveolar lavage confirmed the clinical diagnosis of diffuse alveolar hemorrhage (DAH). After methylprednisolone pulse therapy, Enterococcus faecalis was detected in the blood cultures. A diagnosis of infective endocarditis was made according to the Modified Duke's criteria. The causes of DAH are certainly diverse; however, we should consider infective endocarditis as one of the etiologies of DAH.

Late-Stage Loffler's Endocarditis Mimicking Cardiac Tumor: A Case Report.

Project description:Löffler's endocarditis (cardiac involvement in hypereosinophilic syndrome) is rare yet life-threatening if left untreated. We describe a case of hypereosinophilic syndrome presenting as a cardiac mass with an abnormal electrocardiogram. Diagnostic studies of the cardiac mass strongly suggested a malignant cardiac tumor invading the papillary muscle. Thus, excision of the cardiac mass and endomyocardial resection with mitral valve replacement were successfully performed. Pathology revealed various stages of thrombosis and irreversible myocardial damage caused by eosinophilic infiltration with no malignancy, leading to the correct diagnosis of late-stage Löffler's endocarditis. The subsequent combination of anticoagulation and corticosteroids was effective with a favorable outcome. This case highlights pitfalls in multimodality imaging of cardiac thrombus and the clinical significance of considering Löffler's endocarditis in the diagnostic work-up of a cardiac mass.

Infective Endocarditis Complicated with Anterior Mitral Leaflet Abscess: A Case Report.

Project description:Infective endocarditis (IE) is defined as infection of endocardial surface of the heart. It may include one or more heart valves, the mural endocardium or a septal defect. Its intracardiac effect includes severe valvular insufficiency which may lead to intractable congestive heart failure and myocardial abscess. Infective endocarditis especially complicated by an abscess is associated with high mortality, despite the medical and surgical therapeutic options available. Surgical intervention is indicated in cases of heart failure or uncontrolled infection and sometimes for the prevention of embolic phenomena. We report a case of 42 yrs/M with RVHD admitted in Dr D.Y.Patil hospital, Kolhapur. He had high grade, continuous fever, vomiting, cough with expectoration since 15 days prior to admission. He had prior embolic stroke 2 months back from which he recovered completely. The diagnosis of Infective endocarditis was confirmed clinically & echocardiographically by Duke's criteria. His ECHO showed severe MR, Moderate MS and large vegetations on AML oscillating through mitral orifice along with subvalval (mitral) abscess. Due to severe haematemesis following Mallory weiss tear surgical intervention was not possible. Patient succumbed as a result of refractory pulmonary oedema.

Concurrent diagnosis of infective endocarditis and acute rheumatic fever: A case report.

Project description:Rheumatic heart disease has been classically considered as a risk factor for infective endocarditis (IE). Although valvulitis is frequently present in patients with acute rheumatic fever (ARF), the established valve disease after initial episode of ARF is usually considered as a predisposing factor for IE. We hereby present a biopsy-proven case of IE co-diagnosed with the first episode of ARF. <Learning objective: Infective endocarditis and acute rheumatic fever are both diagnosed with clinical criteria. When both of these conditions are possible in a single case, however, the diagnosis might be challenging. We highlight this issue in the presented case.>.

Project description:BackgroundThe incidence of infective endocarditis (IE) following a MitraClip is rare with 17 reported cases in the literature. The reported mortality rate is high, at 41%, despite both medical and surgical therapies. To date, this is the first documented case of IE following a MitraClip procedure in Australia.Case summaryAn 88-year-old male presented with a 1-week history of confusion and dyspnoea. Clinical examination was significant for a temperature of 37.7°C, a pansystolic murmur and bilateral pitting oedema to mid-shin, but no peripheral stigmata of IE. His history included a MitraClip procedure 11 weeks prior for severe mitral regurgitation. Initial blood cultures grew enterococcus faecalis. A transthoracic echocardiogram did not identify vegetations on the MitraClip. Subsequent transoesophageal echocardiogram (TOE) identified a 4 mm × 2 mm echodensity on the posterior mitral valve leaflet suggestive of IE. He was deemed not suitable for surgical intervention due to poor cognitive reserve and his medical comorbidities, so he commenced intravenous (IV) Ampicillin and Ceftriaxone which was later changed to Benzylpenicillin. Repeat TOE 2 weeks later showed the vegetation to have increased to ∼1 cm in length, so his treatment was reverted to Ampicillin. A further TOE 4 weeks later showed reduction in size to 5 mm × 2 mm. After 6 weeks of IV antibiotics, the patient was discharged on lifelong oral antibiotics.DiscussionInfective endocarditis following MitraClip procedure is rare. This disease has a high mortality rate despite optimal medical and surgical therapy. Increased awareness amongst clinicians is important given an increasing volume of MitraClip procedures.

Catastrophic Perforation in Streptococcus Pneumoniae Aortitis: Complications of Infective Endocarditis in the Current Antimicrobial Era.

Project description:Infectious aortitis is an uncommon but life-threatening cause of aortitis. Given the lack of specific symptoms, establishing the diagnosis is often a challenge. When it is associated with an endovascular infection, such as infective endocarditis, blood cultures may be diagnostic although often limited by low positive predictive value. Imaging studies may reveal characteristic findings, with computerized tomography angiography being the most sensitive. Management includes prompt initiation of antimicrobial therapy followed by surgical intervention, keeping in mind that operative mortality is high due to weakened arterial wall integrity. Here we describe a 25-year-old woman without relevant medical history, who presented to the hospital with subacute onset of fever, back pain and malaise, and was found to have infectious aortitis secondary to Streptococcus pneumoniae endocarditis. Despite appropriate antimicrobial coverage and surgical repair attempts, she succumbed to aortic perforation after a complicated and prolonged hospitalization.
