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...

BACKGROUND: Surgical treatment of active prosthetic aortic valve endocarditis presents a challenge for cardiac surgeons because of tissue friability and destruction caused by infection. Sutureless prostheses, such as the Perceval S® (LivaNova, Saluggia, Italy), have emerged as an option among the different surgical approaches for these complicated cases. METHODS: This study presents data from nine patients who underwent aortic valve re-replacement with the Perceval S® due to active prosthetic aortic valve endocarditis, between January 2014 and August 2016...

Congenital anomalies of the inferior vena cava and its tributaries are quite uncommon; however, since the development of cross-sectional imaging, they have been described more frequently. Most of them are usually asymptomatic, although they can have clinical implications. We report a case of a rare anomaly of the inferior vena cava in a 54-year-old man admitted to our hospital for complicated native aortic valve endocarditis, requiring urgent surgery, and making necessary an alternative venous cannulation for establishing cardiopulmonary bypass circulation...

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...

Staphylococcus aureus infective endocarditis (IE) is a fast-progressing and tissue destructive infection of the cardiac endothelium. The superantigens (SAgs) toxic shock syndrome toxin-1 (TSST-1), staphylococcal enterotoxin C (SEC), and the enterotoxin gene cluster (egc) play a novel and essential role in the etiology of S. aureus IE. Recent studies indicate that SAgs act at the infection site to cause tissue pathology and promote vegetation growth. The underlying mechanism of SAg involvement has not been clearly defined...

Streptococcus bovis endocarditis has 18%-62% association with colonic neoplasms with multivalvular involvement and affects mainly elderly males leading to severe cardiac dysfunction, septic embolization, and neurological complications. The aortic valve is the commonest valve to be affected followed by aortic and mitral valves together. However, involvement of tricuspid valve is extremely rare. There are no reported cases of Streptococcus bovis endocarditis affecting the tricuspid valve in the presence of ventricular septal defect with left to right shunt...

BACKGROUND: Performance of tricuspid annuloplasty (TA) in patients undergoing mitral valve surgery is recommended based on the degree of tricuspid regurgitation and tricuspid annulus size, but is often underused. AIM: To evaluate the impact of combined TA on in-hospital outcome in patients undergoing mitral valve replacement (MVR). METHODS: We selected all consecutive patients who underwent MVR for native valve disease. Clinical, echocardiographic and in-hospital complications were obtained from chart review...

OBJECTIVES: Aortic root abscess (ARA) is a catastrophic complication of aortic root endocarditis, involving both native and prosthetic valves, which often warrants surgical intervention. Currently, aortic valve replacement (AVR) and aortic root replacement (ARR) are the most widely employed techniques. However, evidence that directly compares these methods is scarce. In this meta-analysis, we aimed to describe the surgical outcome of ARA when using different surgical methods. METHODS: In this meta-analysis, we performed literature searches in the EMBASE and PubMed databases and reviewed articles describing postoperative results of ARA that were published before 30 June 2016...

We report a case of infective endocarditis on a Perceval S aortic valve bioprosthesis, and we describe a feasible and useful technique that can help remove the infected valve. These maneuvers consist of an "x-movement" reached with the aid of anatomical forceps. The risk of infective endocarditis in patients with prosthetic valves is a well-known phenomena in cardiac surgery, and it can represent a life-threatening event in many cases. According to guidelines, an emergency surgical intervention is required in case of high risk of embolization, vegetation superior than 1 cm or acute cardiac failure secondary to the acute valve dysfunction...

BACKGROUND: We present our results after elective, isolated David I procedures over the past 20 years. METHODS: Between 1993 and 2015, 197 patients (mean age 46 ± 17 years, 73% men) underwent isolated aortic valve reimplantation using straight tube grafts (David I procedure). Sixty patients (31%) had Marfan syndrome, and 24 (12%) had a bicuspid aortic valve. Twenty-four patients (12%) were operated through upper mini-sternotomy. RESULTS: There were no perioperative deaths...

BACKGROUND: Since FDA approval of the Melody valve, transcatheter pulmonary valve replacement (TPVR) has been offered to an expanding population. Limited data exist regarding the safety and feasibility of TPVR in smaller patients. METHODS: All patients weighing <20 kg who underwent catheterization for percutaneous TPVR at four centers were reviewed. RESULTS: Of the 51 patients reviewed, 43 (84%) had successful valve implantation and 8 (16%) were found not to be candidates due to access veins too small (n = 3), coronary artery/aortic root compression (n = 3), and RVOT too large (n = 2)...

Infective endocarditis (IE) after transcatheter aortic valve implantation (TAVI) is a rare but severe complication. Among 326 patients who underwent TAVI in Grenoble Alpes university hospital, 6 (1.8%) IE cases and 11 (3.4%) bacteraemia cases were identified. No EI was linked to the intervention; one was due to Staphylococcus aureus despite a screening and targeted decolonization strategy. This underscores the need for randomized studies to evaluate benefit and cost-effectiveness of this policy.

Infective endocarditis, caused by Pseudomonas aeruginosa, is rarely seen in clinical practice. It has been reported mainly in intravenous drug abusers (IVDA). We present a case of a 63-year-old male who presented with abdominal pain and fever. Computed tomography (CT) abdomen showed splenic and renal infarct. The blood culture grew Pseudomonas aeruginosa. A transthoracic echocardiogram showed aortic insufficiency with 13 mm mobile vegetation. The patient was started on ceftazidime and tobramycin and, later on, surgery was done for aortic valve replacement...

Background -Surgical aortic root enlargement (ARE) during aortic valve replacement (AVR) allows for larger prosthesis implantation and may be an important adjunct to surgical AVR in the transcatheter valve-in-valve era. The incremental operative risk of adding ARE to AVR has not been established. We sought to evaluate the early outcomes of patients undergoing AVR with or without ARE. Methods -From January 1990 to August 2014, 7039 patients underwent AVR (AVR + ARE, n=1854; AVR, n=5185) at a single institution...

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...
