A 74-year-old male presented to the emergency department 46 days after undergoing an aortic valve replacement. He presented with nonspecific symptoms developed over the previous 15 days, with a new onset of a systolic panfocal murmur. Echocardiography revealed a great vegetation measuring 15 mm by 23 mm causing a severe obstruction of the bioprosthesis. The patient underwent an emergency surgical procedure due to his hemodynamic unsteadiness. During the procedure, we noted an obstruction of the left ventricle outflow tract with pseudoaneurysm of the aortomitral continuity...

BACKGROUND: Mitral para-prosthetic leaks are rare but major complications of mitral heart valve replacements. When they must be re-operated, they are burdened with high mortality rates. We propose to review our surgical experience in terms of approach and type of operation carried out. METHODS: Demographic, preoperative, intraoperative and postoperative characteristics of 34 patients who benefited from a surgical treatment of mitral paravalvular leak at the Brugmann University Hospital between 1996 and 2016 have been gathered retrospectively...

BACKGROUND: Prosthetic valve endocarditis (PVE) due to methicillin resistant Staphylococcus aureus (MRSA) is a rare disease with significant mortality and morbidity. With the emerging resistance and adverse effect profile of vancomycin which is the standard treatment, there is a compelling necessity of an effective alternative for vancomycin. Linezolid is proved as such an agent for infections caused by MRSA in other sites. However to-date the evidence for successful use of linezolid for MRSA prosthetic valve endocarditis is limited only for few case studies...

BACKGROUND: The prevalence of congenital heart disease (CHD) in the adult population is steadily increasing. A substrate of prosthetic material and residual lesions, constantly evolving as surgical techniques change over time, predispose these patients to the potentially devastating complication of infective endocarditis (IE). METHODS: We retrospectively reviewed 2935 patients in our adult CHD database for all cases of endocarditis between 1991 and 2016. Incidence, clinical course and predictors of outcomes were analysed...

Staphylococcus warneri, a coagulase negative staphylococcus, has been isolated in prosthetic device-related infections and has been reported as a rare cause of endocarditis. We report a case of prosthetic aortic valve S. warneri endocarditis, in which the patient lacked typical infectious signs and symptoms, instead presenting with congestive heart failure due to perforation of the valve. Providers should consider endocarditis with a low virulence pathogen such as S. warneri when a patient with a prosthetic valve presents with heart failure, even in the absence of fever, leukocytosis and other infectious symptoms...

Congenital heart disease (CHD) increases the risk of infective endocarditis (IE), though the lesion-specific risk and mortality are poorly defined. Using the population-based Quebec CHD database, we sought to describe the predictors of IE and to evaluate if IE was associated with mortality among adult CHD (ACHD) patients without prior valve replacement surgery. We extracted data on ACHD patients with IE and assessed the lesion-specific incidence of IE, risk factors for IE acquisition, and all-cause 1-year mortality...

A 78-year-old man who had undergone aortic valve and ascending aorta replacements presented with fever and was referred to our hospital. Blood culture revealed Gram-positive cocci, thus antibiotic therapy was started. Brain magnetic resonance imaging showed fresh cerebral infarction without cerebral haemorrhage or mycotic aneurysm. Transoesophageal echocardiogram revealed a vegetation that was attached to the right coronary cusp. The patient underwent successful aortic valve neocuspidization using glutaraldehyde-treated bovine pericardium...

Despite significant technological advances, the diagnosis of infective endocarditis (IE) remains a major challenge, and the condition continues to be associated with significant morbidity and mortality. Valvular vegetations have long been the diagnostic and pathologic hallmarks of IE. However, IE can be diagnosed even in the absence of vegetations using the modified Duke criteria. Vegetation-negative endocarditis is rare, and to the present authors' knowledge no cases of septic emboli in the absence of valvular vegetations have been reported...

Background: Prosthetic valve endocarditis caused by Candida spp. (PVE-C) is rare and devastating, with international guidelines based on expert recommendations consisting in the combination of surgery and subsequent azole treatment. Methods: PVE-C collected in Spain and France between 2001 and 2015 were retrospectively analyzed with a focus on management and outcome. Results: Forty-six cases were followed up for a median of 9 months. Twenty-two (48%) patients had a past history of endocarditis; 30 (65%) cases were nosocomial or healthcare-related, 9 (20%) patients were intravenous drug users...

A 80-year-old man was admitted to catheterization room for an acute infero-lateral ST-elevation myocardial infarction (STEMI). Coronary angiography showed a thrombotic occlusion of the second left marginal branch, and normal other coronary arteries. The thrombo-embolic mechanism of the STEMI, and the infectious context in this patient who had had a transcatheter aortic valve implantation (TAVI) two months earlier, led us to suspect a bioprosthesis endocarditis. It was confirmed by transthoracic and transoesophageal echocardiography, which showed an aortic-mitral curtain abscess and aortic bioprosthesis vegetations, associated to Enterococcus faecalis bacteriemia...

Aims: To support decision-making regarding prosthetic valve selection in non-elderly adults, we aim to provide a detailed overview of outcome after contemporary mechanical aortic valve replacement (AVR). Methods and results: A systematic review was conducted for papers reporting clinical outcome after AVR with bileaflet mechanical valves with a mean patient age ≥18 and ≤55 years, published between 1 January 1995 and 31 December 2015. Through meta-analysis outcomes were pooled and entered into a microsimulation model to calculate (event-free) life expectancy and lifetime event risk...

Endocarditis of a prosthetic heart valve is a life-threatening condition that is associated with high morbidity and mortality. Perivalvular extension in infective endocarditis includes complications such as periannular or intramyocardial abscesses, pseudoaneurysms and fistulae. The incidence of perivalvular extension ranges from 10 to 30% in native valve endocarditis and 30 to 55% in prosthetic aortic-valve endocarditis. Herein, we describe a case of a 66-year-old man who presented endocarditis of a prosthetic aortic valve complicated by infective pseudoaneurysm with localization next to the right coronary sinus of Valsalva...

Introduction.Listeria monocytogenes is a rare etiology of infectious endocarditis with only 30 cases of prosthetic valve and about twice as many native valve infections described in the literature. We describe an unusual presentation of an endovascular embolic phenomenon with associated lower extremity mycotic aneurysm due to Listeria monocytogenes prosthetic aortic valve and aortic endograft infection. Case presentation. This is a case of an elderly gentleman with prior history of bioprosthetic aortic valve placement and aortic arch repair who was admitted with several weeks of constitutional symptoms and left lower leg pain...

BACKGROUND: Sepsis and septic shock are common presentations of infective endocarditis (IE), but little is known about clinical characteristics in this group of patients, use of surgical treatment, and their associations with outcome. We sought to determine the influence of cardiac surgery (CS) on the outcome of patients with IE in different stages of sepsis severity. METHODS: Two hundred ninety four patients with definite IE native or prosthetic valve IE admitted between 2000 and 2011...

OBJECTIVE: Optimal valve substitute for young patients with aortic valve endocarditis remains controversial. Given its better resistance to infection, the Ross procedure is an attractive alternative to prosthetic valve replacement or homograft implantation. The objective of this study was to assess long-term outcomes of the Ross procedure in this indication. METHODS: From 01/1991 to 04/2017, 190 patients underwent a Ross procedure at our institution. Acute endocarditis was the indication for operation in 19 patients, including 6 patients with a bicuspid aortic valve...

OBJECTIVE: The rarity of invasiveness of right-sided infective endocarditis (IE) compared with left-sided has not been well recognized and evaluated. Thus, we compared invasiveness of right- versus left-sided IE in surgically treated patients. PATIENTS AND METHODS: From January 2002 to January 2015, 1292 patients underwent surgery for active IE, 138 right-sided and 1224 left-sided. Among patients with right-sided IE, 131 had tricuspid and 7 pulmonary valve IE; 12% had prosthetic valve endocarditis...
