Aims: Preliminary data on Sapien 3 valve (S3-THV) use for transcatheter aortic valve implantation have shown an increased permanent pacemaker implantation (PPMI) rate with respect to Sapien XT valve. Aim of this study was to investigate the role of S3-THV position in the left ventricular outflow tract (LVOT) on electrocardiographic changes suggestive of atrioventricular (ΔPR) and/or intraventricular (ΔQRS) conduction abnormalities and 30 days PPMI rate. Methods and results: Eighty-six consecutive patients treated with S3-THV were included in the study...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) in patients with bicuspid aortic valve stenosis (AS) is being increasingly performed. OBJECTIVES: From the Bicuspid AS TAVR multicenter registry, the procedural and clinical outcomes in patients with bicuspid versus tricuspid AS were compared. METHODS: Outcomes of 561 patients with bicuspid AS and 4,546 patients with tricuspid AS were compared after propensity-score matching assembling 546 pairs of patients with similar baseline characteristics...

Aims: When compared with the former Sapien XT (XT-THV), the Sapien 3 trans-catheter heart valve (S3-THV) embeds an outer annular sealing cuff to prevent para-valvular regurgitation (PVR). The consequences of this new feature on valve haemodynamics have never been evaluated. We aimed to compare both types of prostheses regarding patient-prosthesis mismatch (PPM). Methods and results: Patients who underwent a TAVR for aortic stenosis were retrospectively included...

Advanced chronic kidney disease (CKD) is associated with poor outcomes in patients who underwent surgical aortic valve replacement, whereas its prognostic role in transcatheter aortic valve implantation (TAVI) remains unclear. This study aimed to investigate outcomes in patients with advanced CKD who underwent TAVI. A total of 1,904 consecutive patients who underwent balloon-expandable TAVI in 33 centers between 2007 and 2012 were enrolled in the Italian Transcatheter Balloon-Expandable Valve Implantation Registry...

Advances in surgical techniques in tetralogy of Fallot (TOF) patients have improved survival of these patients into adulthood. The procedure requires right ventricular outflow tract or trans-annular patch with resultant pulmonary stenosis and/or regurgitation. As such, adult patients seen with this condition may have increasing right ventricular hypertrophy and/or right ventricular dilation. Recently, the Sapien XT valve (Edwards Lifesciences, CA) was approved by the FDA for pulmonary implantation. In some cases, advancing the valve in right ventricular outflow tract is difficult...

OBJECTIVES: The purpose of this in-vitro study was to evaluate the force to debond stainless steel orthodontic brackets bonded to acrylic teeth using different combinations of adhesive and surface treatments. MATERIALS AND METHODS: One hundred prefabricated upper lateral incisor acrylic teeth were divided into 4 equal groups: Transbond XT® adhesive only (Group 1, control), Transbond XT® adhesive with sandblasting (Group 2), Transbond XT® adhesive with abrasion / + methyl methacrylate (MMA) (Group 3) and Triad® Gel only (Group 4)...

Apicoaortic conduit surgery is an option for treating severe aortic stenosis. The implanted conduit valve may eventually fail and require replacement; this is usually performed by repeat surgery. Treating the conduit valve with a standard transcatheter heart valve is an option that has become feasible in recent years. We describe a case of a failed 23 mm CE bioprosthesis that was successfully treated with a 23 mm Sapien XT valve as a valve-in-valve procedure. © 2017 Wiley Periodicals, Inc.

OBJECTIVES: Coronary obstruction (CO) is a rare but serious complication of transcatheter aortic valve implantation (TAVI). There are very limited data regarding CO following TAVI. The aim of this study was to evaluate the incidence and outcomes of CO after TAVI and identify the predictors including the valve type. METHODS: Between October 2006 and March 2015, 1,203 TAVI cases were performed in our institution. Of them, 814 cases whose coronary height was measured using computed tomography for screening were analyzed in this study...

AIM: To assess the effect of four different children's drinks on color stability of resin dental composites. STUDY DESIGN: A total of one hundred and twenty specimens were prepared from Grandio SO, Filtek Z350 XT and Filtek Z250 XT (forty specimens each). Specimens were thermocycled, then each group was further subdivided into four subgroups (n=10) according to the immersion media which were chocolate milk, mango juice, orange fizzy drink, and water (control). The initial color parameters of each specimen were recorded before immersion (baseline) and color change values were recorded three and seven days after immersion in each solution using a digital spectrophotometer...

BACKGROUND: We report a patient who received conventional bilateral deep brain stimulation of the ventral intermediate nucleus of thalamus (Vim) for the treatment of medication refractory essential tremor (ET). After initial beneficial effects, therapeutic efficacy was lost due to a loss of control of his proximal trunkal and extremity tremor. The patient received successful diffusion tensor magnetic resonance imaging fiber tractographic (DTI FT)-assisted DBS revision surgery targeting the dentato-rubro-thalamic tract (DRT) in the subthalamic region (STR)...

OBJECTIVES: The objective of the present study is to evaluate the in vitro cytotoxicity and in vivo biocompatibility of two novel endodontic sealers: RealSeal XT1 and Sealapex Xpress on the subcutaneous connective tissue of mice. MATERIALS AND METHODS: The cytotoxicity was assessed by cell viability using the MTT assay (one-way ANOVA), trypan blue test (Mann-Whitney) and cell apoptosis by flow cytometer. For the subcutaneous study, polyethylene tubes filled with the sealers were implanted in 70 BALB/c mice: 6 experimental groups (n = 10/group) and 2 control groups with empty tubes (n = 5/group)...

BACKGROUND: Transcatheter tricuspid VIV replacement has been proposed as a feasible option for high-risk patients with previous tricuspid valve replacement that undergo valve degeneration causing refractory heart failure. However, little is known about the long-term outcome of patients treated with transcatheter tricuspid VIV. We evaluate the safety of transcatheter tricuspid valve-in-valve (VIV) replacement by using balloon-expandable aortic valve stents and the long-term follow-up. METHODS AND RESULTS: From January 2013 to March 2016, 4 patients underwent transcatheter tricuspid VIV in our center using balloon-expandable Edwards Sapien-XT and Sapien-3 valves...

INTRODUCTION: The aim of this study is to evaluate the effect of different combinations of various surface treatments on the shear bond strength (SBS) of repaired composite resin. MATERIALS AND METHODS: A total of 122 composite samples were prepared from Filtek Z350 XT. Samples were light cured and stored for 6 weeks. Surface treatment of old composite was done in five groups: Group I: bur roughening + phosphoric acid etching, group II: bur roughening + hydrofluoric acid etching + silane coupling agent, group II: air abrasion + phosphoric acid etching, group IV: air abrasion + phosphoric acid etching + silane coupling agent, group V: air abrasion + hydrofluoric acid etching + silane coupling agent...

BACKGROUND: Right bundle branch block is an established predictor for new conduction disturbances and need for a permanent pacemaker (PPM) after transcatheter aortic valve replacement. The aim of the study was to evaluate the absolute rates of transcatheter aortic valve replacement related PPM implantations in patients with pre-existent right bundle branch block and categorize for different transcatheter heart valves. METHODS AND RESULTS: We pooled data on 306 transcatheter aortic valve replacement patients from 4 high-volume centers in Europe and selected those with right bundle branch block at baseline without a previously implanted PPM...
