Prosthetic valve endocarditis is a very grave and often terminal disease. Surgical valve replacement remains the cornerstone treatment for this disease. However, it is often contraindicated. Herein, we describe the implantation under direct visualization of a self-expandable transcatheter heart valve in a prohibitive surgical risk patient with homograft aortic valve endocarditis.

BACKGROUND: Various conduits and stent-mounted valves are used as pulmonary valve graft tissues for right ventricular outflow tract reconstruction with good hemodynamic results. Valve replacement carries an increased risk of infective endocarditis (IE). Recent observations have increased awareness of the risk of IE after transcatheter implantation of a stent-mounted bovine jugular vein valve. This study focused on the susceptibility of graft tissue surfaces to bacterial adherence as a potential risk factor for subsequent IE...

BACKGROUND: There is no international consensus regarding the optimum management of infected aortae (mycotic aneurysms, infected aortic grafts). Neoaortoiliac reconstruction has advantages over extra-anatomical bypass grafting; however, the use of autologous vein is associated with venous hypertension and compartment syndrome, alternatively cadaveric homografts are associated with high rates of perianastomotic hemorrhage, limb occlusion, and pseudoaneurysm. Arterial repair using xenoprosthetic patches is associated with lower infection rates compared to the use of prosthetic material...

Plant grafting has been practiced widely in horticulture and proved as a useful tool in science. However, the mechanisms of graft healing or graft incompatibility remain poorly understood. In this study, Litchi chinensis cv. 'Jingganghongnuo' homograft ('J/J') and 'Jingganghongnuo'/'zhuangyuanhong' heterograft ('J/Z') as compatible and incompatible combination, respectively, was used to study transcriptional changes between incompatible and compatible graft during graft union formation. Anatomical observation indicated that three stages (2 h, 14 d and 21 d after grafting) were critical for graft union formation and selected for high-throughput sequencing...

Ascending aorta reinterventions present a challenge for surgeons as the technical difficulties of the procedure and the complex strategic approach can complicate successful treatment. These patients should be treated by surgical teams with ample experience in aortic diseases as they can be at high risk of mortality. The number of interventions on the ascending aorta and aortic arch and the use of biological conducts (lung autograft, homograft, etc.) have increased in recent years; therefore, the number of reinterventions can also be expected to increase, representing 10% of aortic surgical procedures...

Hypertension-related, calcium-regulated gene (HCaRG/COMMD5) is highly expressed in renal proximal tubules, where it contributes to the control of cell proliferation and differentiation. HCaRG accelerates tubular repair by facilitating re-differentiation of injured proximal tubular epithelial cells, thus improving mouse survival after acute kidney injury. Sustained hyper-proliferation and de-differentiation are important hallmarks of tumor progression. Here, we demonstrate that cancer cells overexpressing HCaRG maintain a more differentiated phenotype, while several of them undergo autophagic cell death...

Reza Tavakoli, Peiman Jamshidi, Max Gassmann
In patients with small aortic roots who need an aortic valve replacement with biological valve substitutes, the implantation of the stented pericardial valve might not meet the functional needs. The implantation of a too-small stented pericardial valve, leading to an effective orifice area indexed to a body surface area less than 0.85 cm(2)/m(2), is regarded as prosthesis-patient mismatch (PPM). A PPM negatively affects the regression of left ventricular hypertrophy and thus the normalization of left ventricular function and the alleviation of symptoms...

Surgical aortic valve replacement with a stented prosthesis has been the standard of care procedure for aortic stenosis. The Perceval (LivaNova, London, United Kingdom) is a sutureless aortic valve bioprosthesis currently implanted in more than 20,000 patients. The purpose of this article was to review the literature available after 9 years of clinical experience of the Perceval aortic valve. PubMED, Embase, and the Cochrane Library databases were searched. A meta-analysis of summary statistics from individual studies was conducted...

Infectious aneurysm is a rare entity associated with significant morbidity and mortality. Current knowledge on pathogenesis, outcome, diagnosis, management, and follow-up remains debatable. We report the case of a patient with Streptococcus pyogenes aneurysm who was successfully treated with a homograft implant and discuss microbiological characteristics, diagnostic methods, and treatment options currently available for this serious disease.

PURPOSE: Despite a substantial amount of literature on tissue-guided regeneration, decellularization process, repopulation time points and stem cell turnover, more in-depth study on the argument is required. Currently, there are plenty of reports involving large animals, as well as clinical studies facing cardiac repair with decellularized homografts, but no exhaustive rodent models are described. The purpose of this study was to develop such a model in rats; preliminary results are also herein reported...

REVIEW
Kathirvel Subramaniam, Soheyla Nazarnia
Prosthesis-patient Mismatch (PPM) is not uncommon with an incidence reported up to 70% after aortic valve (AV) replacement. Severe forms of PPM are less common (up to 20%); PPM can lead to increased short- and long-term morbidity and mortality. It is important to discriminate PPM from other forms of prosthetic valve dysfunction. Sometimes, prosthetic valve degenerative disease may coexist with PPM. Echocardiography plays an important role in the prevention and diagnosis of PPM. Preemptive strategies to prevent PPM include insertion of newer generation prosthetic valves with better hemodynamic characteristics, stentless prosthesis, aortic root enlargement to insert a larger prosthesis, aortic homograft, and transcutaneous AV implantation...

Russell W H Kridel, Angela K Sturm
Dorsal augmentation grafts are used to reconstruct and raise the nasal dorsum in patients with dorsal saddling due to trauma, infection, or previous nasal surgery, as well as in patients with a narrow, congenitally low, and/or wide dorsum. Alloplastic implants and various biomaterials are available for grafting, each with advantages and disadvantages. Although autologous septal cartilage is a preferable and often convenient source of cartilage, it is frequently not sufficient for large volume dorsal augmentation, nor is it available in patients who have had septoplasty, infection, previous rhinoplasty with grafting, or significant trauma...

INTRODUCTION: Vascular homografts are used for limb salvage in cases of graft infection after previous reconstructive vascular surgery or inadequate autologous veins. During multi-organ donation the thoracic aorta segment, aortic bifurcation, iliac arteries, femoral arteries, popliteal arteries, femoral veins and greater saphenous veins can be harvested. Our aim was to optimize the use of homografts by analyzing the results of previous procedures. METHODS: The patient information was processed retrospectively, using the clinical computer system...
