Abstract
AIMS Our aim was to assess the clinical outcomes of the Direct Flow Medical Transcatheter Aortic Valve System (DFM-TAVS), when used in routine clinical practice. METHODS AND RESULTS This is a prospective, open-label, multicentre, post-market registry of patients treated with DFM-TAVS according to approved commercial indications. Echocardiographic and angiographic data were evaluated by an independent core laboratory and adverse events were adjudicated and classified according to VARC-2 criteria by an independent clinical events committee. The primary endpoint was freedom from all-cause mortality at 30 days post procedure. Secondary endpoints included procedural, early safety and efficacy endpoints at 30 days. Two hundred and fifty patients with severe aortic stenosis undergoing transcatheter aortic valve implantation (TAVI) with the DFM-TAVS were enrolled in 21 European centres. The primary endpoint, freedom from all-cause mortality at 30 days, was met in 98% (245/250) of patients. Device success was 83.8%. Moderate or severe aortic regurgitation was reported in 3% of patients, and none/trace regurgitation in 73% of patients. Post-procedural permanent pacemaker implantation was performed in 30 patients (12.0%). CONCLUSIONS The DFM-TAVS was associated with good short-term outcomes in this real-world registry. The low pacemaker and aortic regurgitation rates confirm the advantages of this next-generation transcatheter heart valve (THV).

Abstract
Coronary obstruction during transcatheter aortic valve implantation is a potentially life-threatening complication. Most of the widely used transcatheter heart valves require a certain distance between the basal aortic annular plane and the origins of the coronary arteries. We report the case of a successful valve-in-valve procedure with an Edwards SAPIEN XT valve into a JenaValve as a bail-out procedure in a patient with a low originating left coronary artery and a heavily calcified aorta.

Abstract
Next-generation transcatheter heart valves are designed to overcome procedure-related adverse events such as vascular complications and annulus rupture, and to minimize paravalvular regurgitation. The Direct Flow Medical valve is fully repositionable and shows promising results. The case is presented of Direct Flow Medical valve implantation in a patient with a functional bicuspid aortic valve. Multiple repositioning maneuvers failed to overcome the anatomic difficulties, and this resulted in a moderately high persisting gradient and moderate paravalvular leakage. Surgical valve explantation was necessary which, to the present authors' knowledge, is the first such case of Direct Flow Medical valve explantation to be performed.

Abstract
OBJECTIVES The number of implanted biological valves for treatment of valvular heart disease is growing and a percentage of these patients will eventually undergo a transcatheter valve-in-valve (ViV) procedure. Some of these patients will represent challenging cases. The aim of this study was to develop a feasible algorithm to plan and in vitro simulate a new interventional procedure to improve patient outcome. METHODS In addition to standard diagnostic routine, our algorithm includes 3D printing of the annulus, hydrodynamic measurements and high-speed analysis of leaflet kinematics after simulation of the procedure in different prosthesis positions as well as X-ray imaging of the most suitable valve position to create a 'blueprint' for the patient procedure. RESULTS This algorithm was developed for a patient with a degenerated Perceval aortic sutureless prosthesis requiring a ViV procedure. Different ViV procedures were assessed in the algorithm and based on these results the best option for the patient was chosen. The actual procedure went exactly as planned with help of this algorithm. CONCLUSIONS Here we have developed a new technically feasible algorithm simulating important aspects of a novel interventional procedure prior to the actual procedure. This algorithm can be applied to virtually all patients requiring a novel interventional procedure to help identify risks and find optimal parameters for prosthesis selection and placement in order to maximize safety for the patient.

Abstract
BACKGROUND AND AIMS Bariatric surgery is the most effective treatment for obesity. However, not all patients have similar weight loss following surgery and many researchers have attributed this to different pre-operative psychological, eating behavior, or quality-of-life factors. The aim of this study was to determine whether there are any differences in these factors between patients electing to have bariatric surgery compared to less invasive non-surgical weight loss treatments, between patients choosing a particular bariatric surgery procedure, and to identify whether these factors predict weight loss after bariatric surgery. MATERIAL AND METHODS This was a prospective study of 90 patients undergoing gastric bypass, vertical sleeve gastrectomy, or adjustable gastric banding and 36 patients undergoing pharmacotherapy or lifestyle interventions. All patients completed seven multi-factorial psychological, eating behavior, and quality-of-life questionnaires prior to choosing their weight loss treatment. Questionnaire scores, baseline body mass index, and percent weight loss at 1 year after surgical interventions were recorded. RESULTS AND CONCLUSIONS Surgical patients were younger, had a higher body mass index, and obesity had a higher impact on their quality of life than on non-surgical patients, but they did not differ in the majority of eating behavior and psychological parameters studied. Patients opting for adjustable gastric banding surgery were more anxious, depressed, and had more problems with energy levels than those choosing vertical sleeve gastrectomy, and more work problems compared to those undergoing gastric bypass. Weight loss after bariatric surgery was predicted by pre-operative scores of dietary restraint, disinhibition, and pre-surgery energy levels. The results of this study generate a number of hypotheses that can be explored in future studies and accelerate the development of personalized weight loss treatments.

Abstract
Since the introduction of anti-VEGF drugs for the treatmet of CNV in age-related macular degeneration (AMD), visual acuity can be stabilised or improved in a significant number of patients. There is an ongoing debate on the safety, efficiency and economic aspects related to current intravitreal therapeutic concepts. Twenty-four to 36 hours after 80 % low-fluence verteporfin photodynamic therapy (PDT) a combined phrarmacosurgical intravitreal therapy for 52 patients with wet AMD was conducted (multiple therapy). By performing a 23-gauge core vitrectomy with the Intrector, an intravitreal substitution with BSS, dexamethasone and bevacizumab was achieved via a self-adapting two-channel cannula for aspiration and injection in one probe tip. After 14 months the mean gain in visual acuity (VA) was 0.18 Snellen lines, with VA stabilisation in 14 / 52 (27 %) and VA gain in 38 / 52 (73 %) of the patients. This safe pharmacosurgical regimen indicated a low intravitreal retreatment rate of (13 / 52) 25 %.

Abstract
Screening for B-cell-specific antibodies in unabsorbed pregnancy sera preselected for weak reactivity in regular HLA-A, -B, and -C screening yielded a relatively high proportion (35/81) of B-cell-specific antibodies. Most B-cell-specific antibodies react broadly, showing inclusion phenomena suggesting 'cross-reactivity' analogous to that observed in HLA-A and -B serology. In control experiments with T-cell-enriched suspensions three antisera reacted with T cells and not with B cells. These antisera are highly associated with HLA-A2 in the unrelated population and segregate with HLA haplotypes in families and with HLA-A in a family with HLA-A, B recombination, Thus it appears that the human equivalents of Ia antigens may include--in analogy to the murine Ia antigens--B cell- as well as T-cell-specific alloantigens.
