G Santarpino, F Vogt
Despite the limited clinical relevance of thrombocytopenia after bioprosthetic aortic valve replacement (AVR), the postoperative depletion of platelet count continues to attract the attention of many authors. The development of thrombocytopenia has been evaluated either in patients receiving a sutureless bioprosthesis (1,2) or in those undergoing transcatheter aortic valve implantation, where cardiopulmonary bypass bears little or no relation to this phenomenon (3). Recently, Sánchez et al. (1) have published their findings on this topic, but their limited experience with the devices used makes their study of doubtful interest...

The use of transcatheter aortic valve replacement (TAVR) has risen dramatically during the past decade. Notably, the procedure can reduce symptoms and improve prognosis in patients who would otherwise be excluded from intervention due to prohibitive surgical risk. During the same time period, the use of percutaneous mechanical circulatory support devices for patients with severe left ventricular dysfunction, including the Impella System (Abiomed, Inc., Danvers, MA, USA), has also increased. These devices provide superior hemodynamic effects compared to intra-aortic balloon pumping...

Coarctation of the aorta (CoA) is a relatively common congenital heart anomaly, and bicuspid aortic valve (BAV) is a common congenital heart disease that coexists with CoA. In larger children and adults with CoA, transcatheter intervention has gained acceptance, but for surgical high-risk patients with aortic stenosis, the use of transcatheter aortic valve implantation (TAVI) has been established. Recently, although favorable data have been reported for TAVI when treating BAV, simultaneous transcatheter intervention for CoA and BAV will prove to be a challenge because of the unique anatomy involved requires multiple procedural steps and also has problems of site access...

BACKGROUND: In order to accommodate transcatheter valves to miniaturized catheters, the leaflet thickness must be reduced to a value which is typically less than that of surgical bioprostheses. The study aim was to use finite-element simulations to determine the impact of the thickness reduction on stress and strain distribution. METHODS: A 23 mm transcatheter aortic valve (TAV) was modelled based on the Edwards SAPIEN XT (Edwards Lifesciences, Irvine, CA, USA)...

OBJECTIVES: The aim of the study was to assess indications, procedural success, complications, echocardiographic, and clinical outcomes of percutaneous pulmonary valve implantation (PPVI) in adult patients with congenital heart disease (CHD). BACKGROUND: PPVI offers a non-surgical treatment option for failing prosthetic conduits in pulmonary position. However, efficacy and clinical outcomes after PPVI are still underreported. METHODS: From January 2008 to March 2016, 25 adult CHD patients with right ventricular outflow tract (RVOT) stenosis and/or pulmonary regurgitation underwent PPVI in our institution...

The interrupted noneverting mattress suture technique is typically used in conventional surgical aortic valve replacement. The continuous suture technique, although faster, has been associated with a higher incidence of paravalvular leak. Using a slightly modified technique to minimize this risk, we investigated whether continuous suturing would shorten aortic cross-clamp time in aortic valve replacement in comparison with interrupted suturing. We reviewed the cases and compared the perioperative data of 60 consecutive patients in Japan and Australia (35 men and 25 women; median age, 70 yr) who had undergone aortic valve replacement with or without septal myectomy...

BACKGROUND: To determine the value of aortic valve repair rather than replacement for valve dysfunction, we assessed late outcomes of various repair techniques in the contemporary era. METHODS: From January 2001 to January 2011, aortic valve repair was planned in 1,124 patients. Techniques involved commissural figure-of-8 suspension sutures (n = 63 [6.2%]), cusp repair with commissuroplasty (n = 481 [48%]), debridement (n = 174 [17%]), free-margin plication (n = 271 [27%]) or resection (n = 75) or both, or annulus repair with resuspension (n = 230 [23%]), root reimplantation (n = 252 [25%]), or remodeling (n = 35 [3...

Transcatheter aortic valve replacement (TAVR) has been approved in the United States for intermediate and high-risk patients with severe symptomatic aortic stenosis. More than 80 000 TAVR procedures have been performed in the United States and the number is growing every year. Two valve designs are approved in the United States including the balloon expandable Edwards Sapien prosthesis and self-expanding CoreValve prosthesis. The PARTNER trial of the Sapien valve, involving patients who were considered inoperable, reported a 19% absolute risk reduction in mortality compared with medical therapy, with a number needed to treat of 5...

BACKGROUND: Coronary artery disease (CAD) is common in patients undergoing transcatheter aortic valve replacement (TAVR). However, the impact of CAD distribution before TAVR on short- and long-term prognosis remains unclear. HYPOTHESIS: We hypothesized that the long-term clinical impact differs according to CAD distribution in patients undergoing TAVR using the FRench Aortic National CoreValve and Edwards (FRANCE-2) registry. METHODS: FRANCE-2 is a national French registry including all consecutive TAVR performed between 2010 and 2012 in 34 centers...

We present a 22-year-old patient with a univentricular heart who had already undergone five open heart surgeries including a Damus-Kaye-Stansel procedure, Fontan completion and tricuspid valve replacement. In addition, epimyocardial pacemaker implantation and repeated revisions had been necessary. He developed symptomatic free regurgitation of the pulmonary portion of his DKS anastomosis. To avoid additional high-risk open-heart surgery, we successfully implanted an Edwards Sapien 3 valve transfemorally in the pulmonary portion of the DKS anastomosis relieving insufficiency...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) is widely applied for the treatment of severe aortic stenosis (AS) in developed countries; however, in China, it is still in the early stage of utilization. On the basis of previous studies, this work explored the feasibility of TAVR in patients with severe AS in China and analyzed the cause of death in four cases. METHODS: This retrospective study included 20 patients who had severe AS and underwent TAVR with a balloon-expandable system (Edwards SAPIEN XT) in our hospital from January 2011 to June 2016...

Extensive mitral annulus calcifications are considered a contraindication for valve surgery. We describe the case of a 76-year-old female with severe mitral and aortic stenosis associated with extensive calcifications of the heart. The patient underwent an open mitroaortic valve replacement using transcatheter aortic valve implantation with an Edwards SAPIEN XT valve (Edwards Lifesciences Corp., Irvine, CA, USA) in the mitral position. The aortic valve was replaced using a stentless valve prosthesis (LivaNova SOLO; LivaNova PLC, London, UK)...

BACKGROUND: Annulus-sparing (AS) repair of tetralogy of Fallot (TOF) carries a potential increased risk reoperation for re-stenosis and unproven benefits on right ventricular (RV) geometry. METHODS: Primary TOF repairs (N=434) between 2000 and 2012 were studied using risk-adjusted parametric techniques. Progression of cardiac dimensions were analyzed using repeated measures regression using reports of all 2,103 echocardiograms undertaken throughout the study period, to maximum follow-up 13...

OBJECTIVE: It has been reported that balloon aortic valvuloplasty immediately before transfemoral or transapical transcatheter aortic valve implantation has mostly little to no clinical value. We aimed to provide data on the need for balloon aortic valvuloplasty in patients undergoing transaortic transcatheter aortic valve implantation. METHODS: Patients undergoing transaortic transcatheter aortic valve implantation with the Edwards SAPIEN XT (Nyon, Switzerland) or 3 transcatheter heart valve were prospectively included at 18 sites across Europe...

Adipose tissue can affect the metabolic control of the cardiovascular system, and its anatomic location can affect the vascular function differently. In this study, biochemical and phenotypical characteristics of adipose tissue from periaortic fat were evaluated. Periaortic and subcutaneous adipose tissues were obtained from areas surrounding the ascending aorta and sternotomy incision, respectively. Adipose tissues were collected from patients undergoing myocardial revascularization or mitral valve replacement surgery...
