ConclusionHealthy BV implanted with C-TAH enabled us to study, for the first time, non-degenerated implanted valve in human. Biomaterial passivation by an organized fibrin deposit and formation of EC monolayer on top achieve an optimal hemocompatibility without any modification of pericardial tissue.

ConclusionsThe risk variant rs6702619 is located in a binding site for NFATC2, modifies DNA shape and decreases enhancer-mediated expression of PALMD. PALMD downregulation in VICs results in actin polymerization, a myofibroblast-like phenotype and promotes fibrosis processes, a key feature in the pathogenesis of CAVS.

MontaigneIntroductionQuantitative assessment of right ventricular (RV) function is difficult with 2D-echocardiography (2D-TTE) and changes in RV longitudinal parameters are surprisingly not predictive of cardiovascular events after surgical Aortic Valve Replacement (SAVR).ObjectiveWe aimed at investigating peri-operative evolution of both RV longitudinal parameters and RV global function (assessed b...

Conclusions: The mortality rate and the risk of thromboembolic events and endocarditis were similar between BP and MP patients. The risk of bleeding was approximately one third lower for BP patients than for MP patients, while the risk of reoperations was more than three times higher for BP patients.Resumo Fundamento: A escolha de pr óteses mecânicas ou biológicas para pacientes com doença de válvula cardíaca ainda não é um consenso. Objetivo: Determinar os desfechos clínicos de próteses mecânicas e biológicas nesses pacientes. Métodos...

AbstractThe aortic and pulmonary allograft heart valves (AHV) are used in the cardiac surgery for replacing the impaired semilunar valves. They are harvested from donor hearts and cryostored in tissue banks. The expiration period was set to 5  years arbitrarily. We hypothesized that their mechanical and structural properties do not deteriorate after this period. A total of 64 human AHV (31 aortic and 33 pulmonary) of different length of cryopreservation (fresh, 0–5, 5–10, over 10 years) were sampled to different tissue strips (arte ry, leaflet, ventriculo-arterial junction) and tested by tensile test ...

Neovasc (NSDQ:NVCN) today claimed a win in its patent infringement war with Edwards Lifesciences (NYSE:EW) subsidiary CardiAQ Valve Technologies, saying a German appeals court dismissed a case there. In June 2017 the District Court in Munich ruled that CardiAQ Valve contributed to the creation of Neovasc’s Tiara transcatheter mitral valve replacement, awarding”co-entitlement” rights to the patent in Europe. Both sides appealed that ruling, in the course of which CardiAQ withdrew its total ownership claim but asserted partial ownership, Vancouver-based Neovasc said today. Munich’s Higher Re...

We read the letter to the Editor by Safer and colleagues regarding the diagnosis of sarcopenia and measurement of muscle mass, with great interest. We fully agree with Safer and colleagues that diagnosis of sarcopenia needs to be comprehensively evaluated. As they point out, the European Working Group on Sarcopenia in Older People (EWGSOP) defined sarcopenia as the presence of both low muscle mass and low muscle function (strength or performance).1 Both the muscle mass and muscle function of the patient should be taken into consideration when evaluating the impact of sarcopenia on clinical outcomes.

We read with great interest the article by Okamura and colleagues,1 who evaluated the impact of sarcopenia on the clinical outcomes after heart valve surgery. They concluded that preoperative sarcopenia defined from the psoas muscle area was associated with long-term survival after valve surgery. Before generating current results, however, we would like to direct readers' attention to some methodologic points.
