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: 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...

AIM: To determine whether the need for additional tricuspid valve repair is an independent risk factor when surgery is required for a left-sided heart disease. METHODS: One hundred and eighty patients (68 ± 12 years, 79 males) underwent tricuspid annuoplasty. Cox proportional-hazards regression model for multivariate analysis was performed for variables found significant in univariate analyses. RESULTS: Tricuspid regurgitation etiology was functional in 154 cases (86%), organic in 16 cases (9%), and mixed in 10 cases (6%), respectively...

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...

Aorto-atrial fistulas are a relatively rare, but potentially life-threatening condition, where an anomalous connection forms between the aortic structures and the cardiac atria. Aorto-atrial fistulas are most often the result of an underlying condition concerning the cardiac structures. It may be congenital, secondary to conditions such as aortic dissection, infective endocarditis, or valve replacement, or iatrogenic in nature. Secondary causes incite local deterioration of cardiac wall integrity leading to formation of fistulous connections, while iatrogenic causes are more traumatic in nature...

Valve-in-valve implantation is an alternative to reoperation for patients with degenerated bioprostheses. This case report presents a 75-year-old woman presenting with worsening dyspnoea according New York Heart Association (NYHA) Class III after she had received a Sorin Perceval® S sutureless valve due to severe aortic valve stenosis 5 years ago. Echocardiography revealed a degenerated Perceval valve with severe valvular aortic regurgitation and stenosis. After exclusion of acute infective endocarditis, an Edwards SAPIEN 3 was implanted leading to an immediate haemodynamic improvement...

OBJECTIVES: Paravalvular leak (PVL) is a major cause of morbidity and mortality after mitral valve replacement. Risk factors and data on long-term surgical outcomes are lacking. METHODS: Between January 1995 and December 2012, 206 [118 males (57%)] patients underwent reoperation due to mitral PVL. Mean age was 64 ± 11 years. Haemolytic anaemia was present in 85 (41%) patients, while 137 (67%) patients were in New York Heart Association Class III or IV. Baseline creatinine was above 1...

Background: Non-beta-hemolytic streptococci (NBHS) are a common cause of infective endocarditis (IE). Echocardiography is used to diagnose IE, but it is not known which patients with NBHS bacteremia should undergo echocardiography. Method: Medical records of patients with NBHS bacteremia in southern Sweden from 2012-2014 were studied retrospectively. The patients were divided into two cohorts. In the first, correlations between the reported data and IE were studied...

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...

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...

Streptococcus mutans, a major pathogen of dental caries, is considered to be one of the causative agents of infective endocarditis (IE). Recently, bacterial DNA encoding 120 kDa cell surface collagen-binding proteins (CBPs) has been frequently detected from S. mutans-positive IE patients. In addition, some of the CBP-positive S. mutans strains lacked a 190 kDa protein antigen (PA), whose absence strengthened the adhesion to and invasion of endothelial cells. The interaction between pathogenic bacteria and serum or plasma is considered an important virulence factor in developing systemic diseases; thus, we decided to analyze the pathogenesis of IE induced by S...

BACKGROUND: Consensus guidelines recommend repair over replacement for the surgical treatment of active native mitral valve infective endocarditis. However, contemporary practice and long-term outcome data are limited. METHODS: Multivariable Cox regression was used to compare outcomes of 1970 patients undergoing isolated primary mitral valve repair (n = 367, 19%) or replacement (n = 1603, 81%) for active infective endocarditis between 1998 and 2010 in New York and California states...

Infective endocarditis (IE) is caused due to the vegetation on the heart valves, myocardium wall, or the pacemaker leads. Vegetation is a lesion that appears as a consequence of successive deposition of platelets and fibrin on the endothelial surface of the heart. Colonies of microbes can be usually found under the vegetation. Heart valves are involved more frequently as compared to other places. Streptococcus mitis, formerly known as S. mitior, is a commensal of the oral flora, however, if there of loss of integrity of the mucous membrane, the infection may disseminate to the blood flow...

Infective endocarditis complicating a quadricuspid aortic valve (QAV) is rare. Previous reports highlight the increased risk for complications, including progressive aortic regurgitation, decompensated heart failure, and valve perforation. Thus, cardiologists must be able to quickly identify QAVs to guide rapid evaluation and treatment. We report a case of infective endocarditis in a QAV identified on echocardiography and effectively managed with medical therapy alone without complications over an 8-year follow-up period...
