INTRODUCTION: The Bentall procedure is a cardiac surgery involving graft replacement of the aortic valve, aortic root and ascending aorta. Graft infection after Bentall's procedure (BGI) is infrequent but severe, and often difficult to diagnose and treat. PATIENTS AND METHODS: A retrospective cohort study was performed using the Bordeaux endocarditis database of adult patients admitted to the Bordeaux University Medical Hospital for BGI between 2008 and 2014. Published case reports were identified in the literature...

OBJECTIVES: Totally endoscopic minimally invasive mitral valve surgery (MIMVS) is technically demanding and often performed with robotic assistance. We hypothesized that three-port video-assisted thoracic surgery (VATS) would facilitate endoscopic MIMVS and evaluated its feasibility and safety. METHODS: From October 2010 to June 2016, we performed first-time MIMVS in 250 consecutive patients (122 male), with median age of 65 years (54-73 years, 25-75 percentile)...

OBJECTIVES: Severe cases of infective endocarditis (IE) of the aortic valve can cause aortic root destruction and affect the surrounding structures, including the aortic-mitral continuity, the anterior mitral valve leaflet and the roof of the left atrium. Reconstruction after resection of all infected tissue remains challenging. We describe our surgical approach and the mid-term results. METHODS: Between January 2004 and December 2015, 35 patients underwent surgery for extensive IE of the aortic valve with destruction of the aortic root, the aortic-mitral continuity and the mitral valve...

A 50-year-old man was admitted with fever and chill sensation 6 months ago. Transthoracic echocardiography (TTE) showed left and right coronary cusp prolapses and a thickened tissue of the aortic curtain. Congestive heart failure due to active infective aortic valve endocarditis was diagnosed, and he underwent aortic valve replacement. The aortic annulus was reconstructed using a glutaraldehydetreated autologous pericardium. Six months after surgery, TTE showed severe aortic regurgitation and saccular change in the aortic annulus...

The present case exemplified the detrimental traits of prosthetic valve endocarditis caused by Propionibacterium acnes. As a baby, the patient had a congenital cardiac defect with truncus arteriosus type I with interrupted aortic arch and open ductus Botalli, and had undergone several operations. However, at 18 months after a Bentall procedure performed 29 years later he presented with major prosthetic dehiscence due to endocarditis. The patient underwent a high-risk reoperation for a re-do Bentall procedure and was treated postoperatively with intravenous antibiotics consisting of vancomycin for five weeks and penicillin and rifampicin each for six weeks...

BACKGROUND: The Sorin Freedom SOLO valve is a third-generation stentless aortic valve which shows beneficial hemodynamic performance compared to stented bioprostheses. Long-term results regarding hemodynamics, the durability of the valve, and patient outcome are scarce, and their acquisition was the aim of this single-center study. METHODS: Between 2005 and 2006, a total of 68 consecutive patients (30 males, 38 females; mean age at surgery 76.1 ± 6.3 years) underwent aortic valve replacement with a Sorin Freedom SOLO prosthesis...

Dissection of the interventricular septum (IVS) is an extremely rare entity. An institutional echocardiographic database was retrospectively reviewed; 13 patients with a diagnosis of IVS dissection were found and confirmed by cardiac surgery. The purposes of the study were: to determine the value of transthoracic echocardiography (TTE) in establishing the diagnosis of IVS dissection, and to detail the TTE features of IVS dissection.Thirteen patients with IVS dissection diagnosed by TTE, 8 males and 5 females were taken from 789,114 TTE studies performed between 1985 and 2014...

OBJECTIVES: Coexisting aortic root and mitral valve pathology is increasingly recognized among patients undergoing surgery. We characterized the pathology and surgical outcomes of patients with combined aortic root and mitral disease. METHODS: From 1987 to 2016, 118 patients (age 52.40 ± 17.71 years) underwent concomitant aortic root and mitral procedures (excluding aortic stenosis, endocarditis, and reoperations). Aortic root pathologies included degenerative aneurysm (94%) and aortic dissection (6%)...

Pseudoaneurysm of the mitral-aortic intervalvular fibrosa (P-MAIVF) is a rare complication of infective endocarditis and trauma, particularly of aortic valve surgery. Clinical symptoms are usually unspecific and generally due to complications. Transesophageal echocardiography (TEE) is the most commonly used exam to diagnose P-MAIVF. The main echocardiographic feature is the presence of a cavity communicating with the left ventricular outflow tract that expands during systole and collapses during diastole. Most frequent complications are formation of a fistulous tract and compression of adjacent structures...

A 40-year-old man underwent 4 aortic surgeries because of endocarditis and subsequent prosthesis dehiscence. At the last recurrence he presented with acute severe aortic regurgitation of a Pericarbon Freedom (LivaNova plc, London, UK) stentless bioprosthesis and a morphologically disarranged aortic root. He also presented with left ventricular dysfunction and a very low origin of the left coronary artery. Therefore, a fifth redo aortic valve replacement was considered at high surgical risk. Accordingly, before listing the patient for a heart transplantation, a transcatheter valve-in-valve implantation with the JenaValve (JenaValve Technology, GmbH, Munich, Germany) prosthesis was performed...

A 28-week-old fetus was detected to have a single left atrial mass in prenatal ultrasound. Postnatal echocardiography showed an aneurysm between the anterior mitral leaflet and aortic valve, to the left of atrioventricular junction and communicating with the left ventricle through a narrow mouth. It probably originated from the mitral-aortic intervalvular fibrous tissue and an inherent weakness at this site might be the cause. Reported cases of pseudoaneurysm of mitral-aortic intervalvular fibrosa and subvalvular ventricular aneurysms seen following infective endocarditis, surgery, or trauma seem to have a similar anatomical background...

INTRODUCTION: Neisseria macacae is a Gram-negative diplococcus, found in the oropharynx of healthy Rhesus Monkeys. Infections caused by N. macacae in humans are extremely rare. CASE PRESENTATION: We present here the first case of N. macacae infective endocarditis in a 65-year-old man with a native aortic valve infection complicated by a peri-aortic abscess. N. macacae was isolated from blood culture and was found on the cardiac valve using 16S rDNA detection. Despite an appropriate antibiotic therapy, and aortic homograft replacement, and mitral repair, the patient died 4 days after surgery from a massive hemorrhagic stroke...

OBJECTIVE: Minimally invasive surgery through an upper hemisternotomy for aortic valve replacement has become the routine approach with excellent results. Actually, the same minimally invasive access is used for complex ascending aorta procedures only in few centers. We report our experience with minimally invasive approach for aortic valve and ascending aorta replacement using Bentall technique. METHODS: From January 2010 to November 2015, a total of 238 patients received ascending aorta and aortic valve replacement using Bentall De Bono procedure at our institution...

Infective endocarditis (IE) is a serious infectious condition with high morbidity and mortality in patients with end-stage renal disease (ESRD). It has been particularly associated with recurrent bacteremia due to vascular access via lumen catheters. The most common pathogen is Staphylococcus (S.) aureus, and most affected valve is mitral valve, which frequently calcified. Two patients with ESRD who received hemodialysis treatment via tunneled catheters, aged 56 and 88 years, were admitted with fever and high troponin level...

The brucellosis with multi-organ involvement in a patient with a history of the composite aortic graft (Bentall procedure) and Hepatitis B infection is rare. A 35-year-old man presented to us with fever and loss of consciousness. Four years ago, he was IDU and underwent cardiac surgery because of endocarditis. Recently lumbar spondylodiscitis was diagnosed. The Wright (1/320) and Coombs Wright tests (1/640) were positive. After CNS imaging, lumbar puncture was done. The CSF pleocytosis was lymphocyte dominant...

The case is presented of a 72-year-old male patient suffering from active infective aortic prosthetic endocarditis two months after emergency surgery with aortic valve implantation, and who underwent aortic arch reconstruction using a Dacron patch, due to the spontaneous post-procedural migration of a transcatheter-implanted aortic valve. The heart team considered transcatheter valve implantation (TAVI) due to the increased operative risk demonstrated by a EuroSCORE II of 10.9%, including chronic obstructive pulmonary disease (GOLD 3), cirrhosis (Child-B), esophageal varicose stage 2, chronic renal failure stage 3, and reduced left ventricular ejection fraction...
