Staphylococcus lugdunensis (S. lugdunensis) is a coagulase negative staphylococcus (CoNS) that can cause destructive infective endocarditis. S. lugdunensis, unlike other CoNS, should be considered to be a pathogen. We report the first case of S. lugdunensis endocarditis causing ventricular septal defect and destruction of the aortic and mitral valves. A 53-year-old male with morbid obesity and COPD presented with intermittent fever and progressive shortness of breath for 2 weeks. Chest examination showed bilateral basal crepitations, and a grade 2 systolic murmur along the right sternal border...

Infective endocarditis (IE) of the left heart is the most frequent type of IE in chronic hemodialysis (CHD) (in 90% of cases) whereas involvement of the right heart is rare. The aim of this study was to determine the clinical, biological, and echocardiographic characteristics, as well as the prognosis of IE in CHD. This is a retrospective study conducted at the Center of Nephrology and Hemodialysis in Oujda, Morocco. Over a period of 56 months, we compiled data on a series of 11 CHD patients with IE. Their mean age was 40...

INTRODUCTION: The term "predisposing heart condition" is used as an indication of antimicrobial prophylaxis to prevent infective endocarditis (IE) and as a criterion for diagnosing IE according to modified Duke criteria. The purpose of this survey was to elaborate clinician's knowledge and opinion on relevant heart conditions as a Duke minor criterion for the diagnosis of IE. METHODS: A questionnaire was created that consisted of two knowledge and two opinion questions on the term predisposing heart condition...

A woman aged 36 years G2P1 presented at our outpatient clinic with symptoms of discomfort, dyspnoea and fever at a gestational age of 17 weeks. She was subsequently diagnosed with severe endocarditis with a large vegetation on the mitral valve. She underwent open chest mitral valve surgery while on cardiopulmonary bypass (CPB) within a few days. Such surgical intervention is not only associated with increased maternal risks, but also with severe fetal morbidity and mortality. In such patients, certain perioperative measures can diminish these risks...

OBJECTIVE: The majority of cardiovascular diagnoses in the Danish National Patient Registry (DNPR) remain to be validated despite extensive use in epidemiological research. We therefore examined the positive predictive value (PPV) of cardiovascular diagnoses in the DNPR. DESIGN: Population-based validation study. SETTING: 1 university hospital and 2 regional hospitals in the Central Denmark Region, 2010-2012. PARTICIPANTS: For each cardiovascular diagnosis, up to 100 patients from participating hospitals were randomly sampled during the study period using the DNPR...

The epidemiology, clinical presentation, and treatment of infective endocarditis (IE) has significantly changed over the past few years in developed countries. However, relevant data from developing countries are different and remain scarce. The objective of this study was to evaluate the clinical presentations, treatment and outcomes of IE patients in a tertiary hospital in East China over an 8-year period. This was a retrospective observational study of consecutive cases of definite or possible IE as per the modified Duke criteria between January 2008 and December 2015...

This study aimed to investigate the incidence, predictors, and clinical outcomes of cardiac tamponade after heart valve surgery. A total of 556 patients who underwent heart valve surgery in a single tertiary center between January 2010 and March 2012 were studied. All patients underwent transthoracic echocardiography (TTE) about 5 days after surgery and TTE was repeated regularly. Patients with suspected acute pericardial hemorrhage were excluded. Cardiac tamponade occurred in twenty-four (4.3%) patients and all underwent surgical or percutaneous pericardial drainage...

Bicuspid aortic valve (BAV) is the most common congenital abnormality of the heart. In this condition, instead of three cusps, the aortic valve has two cusps. Children with congenital heart diseases are at increased risk of developing oral diseases, such as: higher number of decayed teeth, developmental anomalies, periodontal disease, malocclusion, dental crowding, as well as susceptibility to develop infective endocarditis from bacteremia caused by chronic poor oral health. However, little information is available regarding oral manifestations and their management in patients with congenital heart defects, despite the importance of these diseases...

BACKGROUND AND OBJECTIVES: Compared with conventional treatment, early surgery significantly reduced the composite end point of all-cause death and embolic events during hospitalization, but long-term data in this area are lacking. This study sought to compare long-term outcomes of early surgery with a conventional treatment strategy in patients with infective endocarditis (IE) and large vegetations. SUBJECTS AND METHODS: The Early Surgery versus Conventional Treatment in Infective Endocarditis (EASE) trial randomly assigned patients with left-sided IE, severe valve disease and large vegetation to early surgery (37 patients) or conventional treatment groups (39 patients)...

The most common cardiovascular presentation of brucellosis (a zoonotic infection) in Iran is aortic valve endocarditis. Brucellosis is a systemic infection and may involve any congenital heart defect with various clinical signs and symptoms. We report brucella endocarditis in an atrial septal defect (ASD) in a 55-year-old man who presented with fever and hemiplegia. Echocardiography showed a secundum ASD with large vegetations of 0.5×1 cm arising from the rim of the ASD. Serological analysis was positive for Brucella agglutinin, thus confirming the diagnosis...

Background. Heart disease is the leading cause of nonobstetric mortality in pregnant women. Because of high risk, medical management represents the first line of treatment. However, when medical treatment fails, cardiac surgery becomes necessary. Case Presentation. A 27-year-old female who underwent successfully cardiac surgery three times within 3 years. At the first time, she had an aortic valve replacement at 25 weeks of gestation after an infectious endocarditis complicated with an ischemic stroke. At 39 weeks of gestation, she had delivered, vaginally, a healthy baby boy weighing 2800 g...

We describe a retired physician who presented with visual disturbance and systemic symptoms. The presence of general malaise, headache and scalp tenderness, with raised inflammatory markers, suggested that giant cell arteritis (GCA) was the likely diagnosis. Rapid response to initial steroid therapy and histological evidence of inflammation in the temporal artery supported this diagnosis. The character of these visual symptoms was, however, atypical for GCA. The patient, who had heart valve disease, subsequently deteriorated and developed further symptoms warranting investigation of bacterial endocarditis...

A man aged 77 years with postrenal transplant lymphoproliferative disease was admitted with high fever, elevated inflammatory markers and a heart murmur. Blood cultures grew Enterococcus faecalis and he was found to have mitral valve endocarditis on echocardiogram and subsequently started on appropriate antibiotics. 5 days into treatment, he developed ocular symptoms and 3 days later, he had irreversible monocular visual loss. He was seen by the ophthalmology team who diagnosed endogenous endopthalmitis secondary to bacteraemic spread from his endocarditis...

REVIEW
Mehrdad Namdari, Ali Eatemadi
Heart valves are currently under thorough investigation in tissue engineering (TE) research. Mechanical and biological heart valve prostheses which are recently used have several shortcomings. While allogenic and xenogenic biological prostheses are related to graft rejection, degeneration and thrombosis, resulting in a high rate of reoperation. Mechanical prostheses on the other hand are based on metallic, carbon, and polymeric components, and require continuous treatment with anticoagulant, which result in adverse reactions, e...

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.

We report a case of isolated native tricuspid valve infective endocarditis caused by Coagulase Negative Staphylococcus in a non-IV drug abuser without structural heart disease. Early diagnosis and prompt initiation of appropriate treatment saved the patient without surgical intervention. The recent trend of Coagulase Negative Staphylococci (CoNS) causing native valve endocarditis (NVE) is reviewed with literature.

A 65-year-old Japanese man was admitted with a 4-month history of fatigue and exertional dyspnea. Transthoracic echocardiography revealed a vegetation on the aortic valve and severe aortic regurgitation. Accordingly, infective endocarditis and heart failure were diagnosed. Although a blood culture was negative on day 7 after admission, a prolonged blood culture with subculture was performed according to the patient's history of contact with cats. Consequently, Bartonella henselae was isolated. Bartonella species are fastidious bacteria that cause blood culture-negative infective endocarditis...

End stage renal disease has a list of consequences, cardiovascular being the most common. Inefficient dialysis can cause significant deposition of calcium all over the body, including heart valves making heart function impaired. We illustrate a case of 38-year-old female with end stage renal disease on peritoneal dialysis. The patient had been complaining of pain and swelling of the right hand for the last few months and had been seen by hand surgeon and was admitted electively for the biopsy of hand lesions...

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...
