BACKGROUND: The impact of various post-procedural complications after transcatheter aortic valve implantation (TAVI) on resource use and their consequences in the German reimbursement system has still not been properly quantified. METHODS: In a retrospective observational study, we use data from the German DRG statistic on patient characteristics and in-hospital outcomes of all isolated TAVI procedures in 2013 (N = 9147). The impact of post-procedural complications on reimbursement, length of stay and mechanical ventilation was analyzed using both unadjusted and risk-adjusted linear and logistic regression analyses...

BACKGROUND: The performance of emerging transcatheter aortic valve implantation (TAVI) clinical prediction models (CPMs) in national TAVI cohorts distinct from those where they have been derived is unknown. This study aimed to investigate the performance of the German Aortic Valve, FRANCE-2, OBSERVANT and American College of Cardiology (ACC) TAVI CPMs compared with the performance of historic cardiac CPMs such as the EuroSCORE and STS-PROM, in a large national TAVI registry. METHODS: The calibration and discrimination of each CPM were analyzed in 6676 patients from the UK TAVI registry, as a whole cohort and across several subgroups...

BACKGROUND: Patients with failed bioprostheses are an increasing population at high risk for redo surgery. Valve-in-valve transcatheter aortic valve implantation is a promising alternative but a limited number of first-generation devices have proven efficacy in all cases. METHODS: Patients with degenerated bioprostheses at high risk for redo surgery were included in the registry after being assigned to valve-in-valve intervention by a local heart team. Main basal and follow-up data (at 1 month and 6 months) of patients undergoing valve-in-valve transcatheter aortic valve implantation with the Lotus valve system (Boston Scientific, Natick, MA) in three high-volume Italian centers were entered in the registry...

The comparative outcomes of transcatheter aortic valve replacement (TAVR) versus surgical aortic valve replacement (SAVR) in diabetes mellitus (DM) patients are scarce. We aimed to assess and compare the outcomes of TAVR versus SAVR in DM patients using the Nationwide Inpatient Sample database from 2011 to 2013. A complete case analysis was performed for the multivariate analysis and cases with missing data were excluded. The primary end point was in-patient all-cause mortality and secondary outcomes were perioperative complications...

BACKGROUND: Aortic valve predilation with balloon aortic valvuloplasty (BAV) is recommended before transcatheter aortic valve implantation (TAVI), despite limited data around the requirement of this preprocedural step and the potential risks of embolization. This study aimed to investigate the trends in practice and associations of BAV on short-term outcomes in the UK TAVI registry. METHODS AND RESULTS: Eleven clinical endpoints were investigated, including 30-day mortality, myocardial infarction, aortic regurgitation, valve dysfunction, and composite early safety...

Current guidelines for patients who are undergoing transcatheter aortic valve implantation but who do not require anticoagulation recommend double antiplatelet therapy for 3-6 months after the procedure, followed by aspirin indefinitely. However, these guidelines are based on expert consensus rather than clinical trials. Several randomized trials are currently evaluating alternative antithrombotic strategies, and recommendations will likely change when their results become available.

BACKGROUND: There are currently only limited data focusing on transcatheter aortic valve implantation (TAVI) for bicuspid aortic valves (BAV) patients using the Edwards SAPIEN (Irvine, CA, USA) 3 (S3) valve. The aim of this study was to evaluate the feasibility and efficacy of TAVI using the S3 in patients with BAV. METHODS: A total of 153 TAVI cases performed with the S3 were included. BAV was detected by multidetector computed tomography (MDCT) in 10 (7%) patients...

OBJECTIVES: This study sought to update benchmark values to use a quality measure prospectively. BACKGROUND: Congenital Cardiac Catheterization Outcomes Project - Quality Improvement (C3PO-QI), a multi-center registry, defined initial radiation dose benchmarks retrospectively across common interventional procedures. These data facilitated a dose metric endorsed by the American College of Cardiology in 2014. METHODS: Data was collected prospectively by 9 C3PO-QI institutions with complete case capture between 1/1/2014 and 6/30/2015...

BACKGROUND: The authors present their own experience of the treatment of patients qualified for transcatheter aortic valve implantation (TAVI) carried out in a modern hybrid operating room. The objective of the present study was to demonstrate the initial results of conducting anaesthesia in high-risk patients qualified for the TAVI procedure (transcatheter aortic valve implantation). In addition, the authors' aim was also to point out to the special challenges of an anaesthesiologist conducting local anaesthesia in such a type of procedures and to evaluate the safety and efficacy of the TAVI procedure conducted under remifentanil analgosedation...

OBJECTIVES: The authors present the UK and Irish real-world learning curve experience of the Evolut R transcatheter heart valve. BACKGROUND: The Evolut R is a self-expanding, repositionable, and fully recapturable second-generation transcatheter heart valve with several novel design features to improve outcomes and reduce complications. METHODS: Clinical, procedural, and 30-day outcome data were prospectively collected for the first 264 patients to receive the Evolut R valve in the United Kingdom and Ireland...

Transcatheter aortic valve implantation is a recent innovation in the treatment of severe aortic stenosis. On the other hand, several reports suggested that minimally invasive aortic valve replacement (MICS-AVR) is likely to be associated with reduced postoperative discomfort and faster recovery. Of note, an upper partial sternotomy for isolated aortic valve replacement( L-shaped MICS-AVR) has been accepted as the most common approach to the MICS-AVR. Since October 2013, we have preformed L-shaped MICS-AVR at our hospital...

A 40-year-old man underwent 4 aortic surgeries because of endocarditis and subsequent prosthesis dehiscence. At the last recurrence he presented with acute severe aortic regurgitation of a Pericarbon Freedom (LivaNova plc, London, UK) stentless bioprosthesis and a morphologically disarranged aortic root. He also presented with left ventricular dysfunction and a very low origin of the left coronary artery. Therefore, a fifth redo aortic valve replacement was considered at high surgical risk. Accordingly, before listing the patient for a heart transplantation, a transcatheter valve-in-valve implantation with the JenaValve (JenaValve Technology, GmbH, Munich, Germany) prosthesis was performed...

BACKGROUND: It is unknown whether circumferential strain is associated with prognosis after treatment of aortic stenosis (AS). We aimed to characterise strain in severe AS, using myocardial tagging cardiovascular magnetic resonance (CMR), prior to and following Transcatheter Aortic Valve Implantation (TAVI) and Surgical Aortic Valve Replacement (SAVR), and determine whether abnormalities in strain were associated with outcome. METHODS: CMR was performed pre- and 6 m post-intervention in 98 patients (52 TAVI, 46 SAVR; 77 ± 8 years) with severe AS...

AIMS: Long-term outcomes are available for first-generation transcatheter heart valves, but data on second-generation devices are scarce. We aim to provide an oversight of all patients implanted with a second-generation valve in our center. METHODS AND RESULTS: From April 2012 to July 2016, 219 patients were enrolled in this prospective single-center experience; they received either the transapical ACURATE TA™ (n=99) or the transfemoral ACURATE neo™ (n=120) prosthesis...

BACKGROUND: The results from the PARTNER 2 trial showed the feasibility of transcatheter aortic valve replacement (TAVR) in intermediate surgical risk patients. Although low risk clinical trials will take time to conclude, some data has emerged comparing TAVR with surgical aortic valve replacement (SAVR) in lower risk patients. METHODS: A Medline search was conducted using standard methodology to search for studies reporting results comparing TAVR and SAVR. Studies were included if the overall mean Society of Thoracic Surgeons Score was less than 4% (or equivalent Euroscore)...
