Prosthetic Valve Endocarditis

Andre Paixao, Mehmet Cilingiroglu
Paravalvular leak (PVL) remains as uncommon but serious complication after surgical prosthetic valve implantation. PVL when associated which congestive heart failure, hemolytic anemia, or infective endocarditis may require percutaneous treatment. High-surgical risk is common in this population. Dedicated PVL devices are lacking often limiting optimal treatment.

Sensitivity and specificity of the modified Duke criteria for native valve endocarditis are both suboptimal, at approximately 80%. Diagnostic accuracy for intracardiac prosthetic material-related infection is even lower. Non-invasive imaging modalities could potentially improve diagnosis of infective endocarditis; however, their diagnostic value is unclear. We did a systematic literature review to critically appraise the evidence for the diagnostic performance of these imaging modalities, according to PRISMA and GRADE criteria...

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...

Cardiovascular implantable electronic device (CIED) infection and prosthetic valve endocarditis (PVE) remain a diagnostic challenge. Cardiac imaging plays an important role in the diagnosis and management of patients with CIED infection or PVE. Over the past few years, cardiac radionuclide imaging has gained a key role in the diagnosis of these patients, and in assessing the need for surgery, mainly in the most difficult cases. Both (18)F-fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) and radiolabelled white blood cell single-photon emission computed tomography/computed tomography (WBC SPECT/CT) have been studied in these situations...

Chronic Coxiella burnetii endocarditis usually develops in people with underlying heart disease and accounts for 60-70% of chronic Q fever. Onset is generally insidious and manifestations are atypical. The authors report a case of Coxiella burnetii prosthetic valve endocarditis in a 53 years- old patient with recurrent mechanical valve dehiscence on mitral position. He lived in a rural area with sheep and goats on the surroundings. During a 9 year- period, he was submitted to three cardiac mitral valve surgeries two of which with no Q fever diagnosis suspicion...

OBJECTIVE: To clarify the mid-term durability of the Trifecta bioprosthesis for aortic valve replacement (AVR). METHODS: We retrospectively analyzed the prospectively collected data of 824 consecutive implants of the Trifecta valve at a single institution. A 100% complete follow-up was available (average duration, 2.2 ± 1.3 years; range, 0.03-6.9 years; 1747.6 patient-years). Echocardiography data at discharge were recorded prospectively. RESULTS: Operative mortality was 3...

BACKGROUND We present a unique case of a 61-year-old female patient with homograft deterioration after redo surgery for prosthetic valve endocarditis with root abscess. CASE REPORT The first operation was performed for type A dissection with root, arch, and elephant trunk replacement of the thoracic aorta. The present re-redo surgery was performed as valve-in-valve with a sutureless aortic bioprosthesis. The postoperative course was uneventful and the patient was discharged on day 6. CONCLUSIONS The current case report demonstrates that sutureless bioprostheses are an attractive option for surgical valve-in-valve procedures, which can reduce morbidity and mortality...

Abiotrophia defectiva, a nutritionally variant streptococci can cause bacteremia, brain abscess, septic arthritis and in rare cases, infective endocarditis, which accounts for 5-6% of all cases. A. defectiva is characteristically difficult to diagnose and the mortality, morbidity and complication rates are high. Here, we discuss a case of infective endocarditis caused by A. defectiva. A 62-year-old female had previously undergone prosthetic valve replacement 6 years prior to admission. She developed infective endocarditis after tooth extraction...

Destructive aortic valve endocarditis is a serious condition that can result in aortoventricular disjunction. The appropriate surgical approach for severe excavating lesions remains a matter of debate. Homografts, prosthetic valves associated with a pericardial patch for annulus repair, and prosthetic valve conduits can be used. We report the technical issue of subcoronary inclusion of the full root Freestyle xenograft for complicated aortic endocarditis extending to the left ventricular outflow tract.

BACKGROUND: Lead-related or valve-related endocarditis can complicate cardiovascular implantable electronic device (CIED) infection in patients with both CIED and prosthetic valves. The objective of this study was to determine the outcomes of transvenous lead extraction for CIED infection in patients with prosthetic valves. METHODS AND RESULTS: We retrospectively screened 794 transvenous lead extraction procedures, between September 1, 2001 and August 31, 2012, at Mayo Clinic to identify patients with prosthetic valves who underwent lead extraction for infection...

Infective endocarditis (IE) is a highly morbid condition in pregnancy which poses both maternal and fetal risk. In majority of cases, endocarditis occurs only on single valve and usually occurs on valve with structural disease or prosthetic valve. Multi-valvular involvement is not common and so we report a case of native triple valve endocarditis as a complication of post abortal sepsis which was successfully treated medically.

OBJECTIVE: To analyze the characteristics and outcome of infective endocarditis (IE) according to the time interval between IE first symptoms and diagnosis. METHODS: Among the IE cases of a French population-based epidemiological survey, patients having early-diagnosed IE (diagnosis of IE within 1 month of first symptoms) were compared to those having late-diagnosed IE (diagnosis of IE more than 1 month after first symptoms). RESULTS: Among the 486 definite-IE, 124 (25%) had late-diagnosed IE whereas others had early-diagnosed IE...

PURPOSE: The diagnosis of prosthetic valve (PV) infective endocarditis (IE) and infection of cardiac implantable electronic devices (CIEDs) remains challenging. The aim of this study was to assess the usefulness of (18)F-FDG PET/CT in these patients and analyse the interpretation criteria. METHODS: We included 41 patients suspected of having IE by the Duke criteria who underwent (18)F-FDG PET/CT. The criteria applied for classifying the findings as positive/negative for IE were: (a) visual analysis of only PET images with attenuation-correction (AC PET images); (b) visual analysis of both AC PET images and PET images without AC (NAC PET images); (c) qualitative analysis of NAC PET images; and (d) semiquantitative analysis of AC PET images...

INTRODUCTION: Due to late complications associated with the use of conventional prosthetic heart valves, several centers have advocated aortic valve repair and/or valve sparing aortic root replacement for patients with aortic valve insufficiency, in order to enhance late survival and minimize adverse postoperative events. METHODS: From March/2012 thru March 2015, 37 patients consecutively underwent conservative operations of the aortic valve and/or aortic root. Mean age was 48±16 years and 81% were males...

We report a case of aortic prosthetic valve endocarditis presenting with subaortic stenosis without perivalvular leakage and vegetations in the left ventricular outflow and right atrium, the latter being attached to the atrioventricular septum. Intraoperatively, an abscess that had formed on the aortic annulus and perforated to the right atrium was unexpectedly found, the fistula being occluded by vegetations. Even when no left-to-right shunts are detected by imaging, vegetations adjacent to the atrioventricular septum may conceal a left ventricle-right atrium fistula, resulting in prosthetic valve endocarditis presenting clinically as subaortic stenosis without perivalvular leakage...

OBJECTIVE: The recent development of the EDWARDS INTUITY Elite™ (EIE) valve system enables the rapid deployment of a prosthetic surgical heart valve in an aortic valve replacement (AVR) procedure via both the minimally invasive (MISAVR) and conventional (CAVR) approaches. In order to understand its economic value, this study performed a cost evaluation of the EIE valve system used in a MIS rapid-deployment approach (MIS-RDAVR) vs MISAVR and CAVR, respectively, compared to standard prosthetic aortic valves...

Complete dehiscence of a composite aortic valve graft with pseudoaneurysm formation is a rare complication following aortic root replacement. This complication often takes place in the setting of acute graft infection and accompanies symptoms of heart failure, valve insufficiency or sepsis. We present a delayed, asymptomatic presentation of this complication in a young man with distant history of aortic root replacement and medically treated prosthetic valve endocarditis a year postoperatively. He had been non-adherent to warfarin over 10 years, but otherwise maintained a healthy life...
