The timely diagnosis of prosthetic heart valve endocarditis remains challenging yet of utmost importance. 18F-fluorodeoxyglucose (18 F-FDG) positron emission/computed tomography (PET/CT) and cardiac computed tomography angiography (CTA) were recently introduced as additional diagnostic tools in the most recent ESC guidelines on infective endocarditis. However, how to interpret PET/CT findings with regard to what is to be considered abnormal, what the potential confounders may be, as well as which patients benefit most from these additional imaging techniques and how to best perform them in these often-complex patients, remains unclear...

Objective: Female sex is a known risk factor for cardiac surgery, and tricuspid valve (TV) disease is more common in women. There are few data on sex-stratified surgical outcomes for isolated TV surgery. An administrative database was used to compare acute in-hospital outcomes between men and women undergoing isolated TV surgery. Methods: Patients aged >18 who underwent TV repair or replacement from 2004 to 2013 were identified using the National Inpatient Sample...

Infective endocarditis (IE) is an infectious disease that affects the endothelium of the large intrathoracic vessels, heart valves, and intra-cardiac foreign body material. A 20-year-old woman was admitted to the cardiology department with complaints of fever and palpitations. Transthoracic echocardiography revealed a bicuspid aortic valve, aortic root enlargement, and aortic coarctation. Transesophageal echocardiography revealed a bicuspid aortic valve, but there was no vegetation. Methicillin-sensitive Staphylococcus aureus was identified on a blood culture...

BACKGROUND: Surgery of the pulmonary valve, right ventricular outflow tract, and pulmonary artery falls under the domain of paediatric cardiac surgery. However, 97 adult patients underwent such operations in our establishment from 1993 to 2016. AIM: This study aims to analyse preoperative risk factors, intraoperative data, postoperative outcomes, and long-term survival to identify the potential predictors of mortality and high-risk patients.
 METHODS: We divided our patient cohort into three groups in accordance with surgical indications: 17 patients with pulmonary valve endocarditis (group A), 70 patients with congenital defects involving the pulmonary valve (group B), and 10 patients who underwent pulmonary valve surgery for other indications, like tumor or other acquired valvular disease (group C)...

Generally, infective endocarditis is found at the left side of the heart. The right side infective endocaritis accounts for only 5~10% of all cases of infective endocarditis. The right side infective endocarditis occurs especially among drug users employing intravenous injection. A typical site of infection is the tricupid valve, and isolated pulmonary valve involvement is rare. It is assumed that its rarity is due to the low pressure gradients within the right heart, the low prevalence of valve disease, and the lower oxygen content of the venous blood...

Aims: Patients with prior infective endocarditis (IE), a prosthetic heart valve, or a cyanotic congenital heart disease (CHD) are considered to be at high risk of IE by guidelines. However, knowledge is sparse on the relative risk of IE between these three groups and compared controls. Methods and results: Using Danish nationwide registries (1996-2015), we identified all patients with prior IE, a prosthetic heart valve, or a complex CHD (defined as tetralogy of Fallot, truncus arteriosus, and transposition of great arteries) as well as matched control populations...

AngioVac is a vacuum-based device approved in 2014 for percutaneous removal of undesirable materials from the intravascular system. Although numerous reports exist with regard to the use of the AngioVac device in aspiration of iliocaval, pulmonary, upper extremity, and right-sided heart chamber thrombi, very few data are present demonstrating its use in treatment of right-sided endocarditis. In this case report, we describe the novel device used in debulking a large right-sided tricuspid valve vegetation reducing the occurrence of septic embolisation and enhancing the efficacy of antibiotics in clearance of bloodstream infection...

Approximately one-third of patients with infective endocarditis require surgical treatment, but the ideal procedure that prevents infection ensures long durability and maintains quality of life remains unclear. A 21-year-old man who was diagnosed with aortic active infective endocarditis was referred to our hospital for surgical treatment. Echocardiography showed bicuspid aortic valve, severe aortic regurgitation, a large vegetation, and a paravalvular abscess. We planned to perform elective surgical treatment after antibiotic therapy; however, progression to heart failure required urgent operation...

Lactobacillus is a genus of Gram-positive, facultative anaerobic/ microaerophilic, rod-shaped bacteria. Lactobacilli constitute a significant component of the human microbiota in the oral cavity, gastrointestinal tract and female urogenital tract. They are also widely used as probiotics. Rarely, especially in patients with impaired immunity or with structural heart disease, do Lactobacilli become the pathogen responsible for serious infections, e.g. infective endocarditis (IE). CASE REPORT: The authors describe a case of an 80-year-old female with a past history of aortic valve replacement, mitral annuloplasty and pacemaker implantation admitted to hospital due to weakening, subfebrile state and chills...

This report describes a case of nonbacterial thrombotic endocarditis caused by Waldenström macroglobulinemia, with diffuse endocardial lesions and involvement of all 4 cardiac valves. A 77-year-old man presented with heart failure due to severe regurgitation of all 4 cardiac valves; surgical repair using bioprosthetic valves was indicated. A pathological study revealed fibrin-triggered thrombus formation that confirmed the diagnosis of nonbacterial thrombotic endocarditis. In cases of nonbacterial thrombotic endocarditis, the underlying cause should be investigated...
