The mainstay for the current treatment of severe aortic stenosis includes surgical aortic valve replacement (SAVR) and transcatheter aortic valve implantation (TAVI). In patients with high operative risk TAVI is established as first line therapy. New data on intermediate and low risk groups demonstrate at least non-inferiority of TAVI against SAVR, and in the near future a consistently rising number of transcatheter procedures may be anticipated. The purpose of this review is to outline the decision making process, hence to illustrate the diagnostic algorithm and to provide criteria for a differentiated approach against the background of recent data...

Aims: To analyse reasons, timing and predictors of hospital readmissions after transcatheter aortic valve implantation (TAVI). Methods and Results: Patients included in the Bern TAVI Registry between August 2007 and June 2014 were analysed. Fine and Gray competing risk regression was used to identify factors predictive of hospital readmission within 1 year after TAVI with bootstrap analysis for internal validation. Of 868 patients alive at discharge, 221 (25.4%) were readmitted within 1 year...

The VARC (Valve Academic Research Consortium) for transcatheter aortic valve replacement set the standard for selecting appropriate clinical endpoints reflecting safety and effectiveness of transcatheter devices, and defining single and composite clinical endpoints for clinical trials. No such standardization exists for circumferentially sutured surgical valve paravalvular leak (PVL) closure. This document seeks to provide core principles, appropriate clinical endpoints, and endpoint definitions to be used in clinical trials of PVL closure devices...

BACKGROUND: Little is known about patients with severe symptomatic aortic stenosis (AS) who receive medical management despite evaluation at a heart valve treatment center. OBJECTIVE: We identified patient characteristics associated with medical management, physician-reported reasons for selecting medical management, and patients' perceptions of their involvement and satisfaction with treatment selection. METHODS AND RESULTS: Of 454 patients evaluated for AS at 9 established heart valve treatment centers from December 12, 2013 to August 19, 2014, we included 407 with severe symptomatic AS...

To investigate the effects of lentiviral vector-mediated shRNA suppressing CXCR7 on tumour invasion and metastasis in hepatocellular carcinoma (HCC) after transcatheter arterial chemoembolization (TACE). HCCLM3 cell lines were cultured and assigned into the CXCR7-shRNA, negative control (NC) and blank groups. The qRT-PCR and Western blotting were applied to detect the mRNA and protein expressions of CXCR7, CXCR4 and MMP-2 in HCCLM3 cells. Cell proliferation and invasion were evaluated by MTT and Transwell assays...

OBJECTIVES: This study sought to use a new catheter technique to split the anterior mitral valve leaflet (AML) and prevent iatrogenic left ventricular outflow tract (LVOT) obstruction immediately before transcatheter mitral valve replacement (TMVR). BACKGROUND: LVOT obstruction is a life-threatening complication of TMVR, caused by septal displacement of the AML. METHODS: The procedure was used in patients with severe mitral valve disease and prohibitive surgical risk...

Nickel-titanium alloys are commonly adopted for producing cardiovascular minimally invasive devices such as self-expandable stents, aortic valves and stent-grafts. These devices are subjected to cyclic loads (due to blood pulsatility, leg or heart movements), that can induce fatigue fracture, and may also be subjected to very large deformations (due to crimping procedure, a tortuous physiological path or overloads), that can induce material yield. Recently, the authors developed a new constitutive model that considers inelastic strains due to not-completed reverse phase transformation (not all the stress-induced martensite turns back to austenite) or/and plasticity and their accumulation during cyclic loads...

BACKGROUND/AIM: Transcatheter aortic valve implantation (TAVI) is an innovative approach to the treatment of aortic stenosis (AS) as an alternative to surgery in high-risk patients. Mean platelet volume (MPV) is considered an indicator of endothelial dysfunction, platelet function, and activation. In this study, we aimed to investigate MPV changes in patients undergoing TAVI. MATERIALS AND METHODS: This study included 100 patients diagnosed with symptomatic severe AS and treated with TAVI between July 2011 and August 2013...

Although heart failure is managed medically most of the time, heart transplantation is still last resort for selected end-stage heart failure patients with noncompaction cardiomyopathy. Presently described for the first time is case of pediatric patient with noncompaction cardiomyopathy who was initially referred to our hospital for heart transplant but underwent PDA repair and improved clinically without need for heart transplant.

Objective: To evaluate our experience following the introduction of a percutaneous program for endovascular treatment of aortic diseases using Perclose Proglide® assessing efficacy, complications and identification of potential risk factors that could predict failure or major access site complications. Methods: A retrospective cohort study during a two-year period was performed. All the patients submitted to totally percutaneous endovascular repair (PEVAR) of aortic diseases and transcatheter aortic valve implantation since we started the total percutaneous approach with the preclosure technique from November 2013 to December 2015 were included in the study...

Postpartum haemorrhage (PPH) remains one of the leading causes of maternal death worldwide and can be classified as either immediate (primary) or delayed (secondary) according to the onset time - before or after 24 hours postpartum. Uterine pseudoaneurysm is a rare cause of PPH that has been suggested to arise from abnormal vascular regression and a recurrent vascular healing state, such as a vascular stricture and relaxation with thrombin deposits after placental expulsion. With advances in multidetector computed tomography, 3D-computed tomography with angiography can aid in identifying the location and originating vessels of the pseudoaneurysm via fast and clear 3D images...
