BACKGROUND: Treatment for patients with end-stage renal disease (ESRD) and severe aortic stenosis (AS) includes balloon aortic valvuloplasty (BAV), surgical (SAVR), or transcatheter (TAVR) aortic valve replacement. We compared outcomes among these strategies. METHODS: A retrospective review of patients with ESRD undergoing treatment for severe AS between 07/2007 and 06/2015 was performed at our center. Patients were classified based on treatment: BAV-only, TAVR, or SAVR...

In the recent decade medicine developed far beyond people's mind, as transcutaneous aortic valve replacement(TAVR), Mitraclip et al. As recent development of information technology has changed to real time information system in the world, international communication in the field of cardiovascular surgery has also changed to become large in volume, rapid in time and frequent and convenient in use. The Asian Society for Cardiovascular and Thoracic Surgery(ASCVTS) which has a major role of international communication in the field cardiovascular surgery in Japan, has developed to become one of the major international academic society...

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)...

Importance: In clinical trials, transcatheter aortic valve replacement (TAVR) has been shown to improve symptoms and quality of life. As this technology moves into general clinical practice, evaluation of the health status outcomes among unselected patients treated with TAVR is of critical importance. Objective: To examine the short- and long-term health status outcomes of surviving patients after TAVR in the context of an unselected population. Design, Setting, and Participants: This observational cohort study included patients with severe aortic stenosis who underwent TAVR in the Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy (TVT) Registry from November 1, 2011, to March 31, 2016, at more than 450 clinical sites...

OBJECTIVE: Our objective was to evaluate sex-differences in outcomes after trans-catheter aortic valve replacement (TAVR) in a population-based cohort from Ontario, Canada. BACKGROUND: Prior studies comparing outcomes in men and women after TAVR have yielded divergent results. Some studies have suggested that women have better survival than men while others have not corroborated this finding. METHODS: A retrospective observational cohort study was conducted using chart abstraction data on all TAVR procedures performed between 2007 and 2013 in Ontario, Canada...

RATIONALE AND OBJECTIVES: Multimodality evaluation of the aortic annulus is generally advocated to plan for transcatheter aortic valve replacement (TAVR). We compared aortic annular measurements by cardiac computed tomography angiography (cCTA) to three-dimensional transesophageal echocardiography (3D-TEE), and also evaluated the use of semi-automated software for cCTA annular measurements. MATERIALS AND METHODS: A retrospective cohort of 74 patients underwent 3D-TEE and electrocardiogram-gated cCTA of the heart within 30 days for TAVR planning...

AIMS: The impact of left ventricular outflow tract calcification (LVOT-CA) on Sapien 3 transcatheter aortic valve replacement (S3-TAVR) is not well understood. The aims of the present study were to determine optimal device sizing for S3-TAVR in patients with or without LVOT-CA and to evaluate the influence of residual paravalvular leak (PVL) on survival after S3-TAVR in these patients. METHODS AND RESULTS: This study analyzed 280 patients (LVOT-CA=144, no LVOT-CA=136) undergoing S3-TAVR...

Increasing annular calcification portends more adverse outcomes and worse hemodynamic results following percutaneous structural heart interventions. Though the Direct Flow prosthesis did not appear to have significantly different post-procedural gradients based on aortic valve calcium burden in a selected group of patients, the average residual gradients were relatively high in all cases and the presence of a paravalvular leak was more common with increasing valvular calcification. It is unclear how the Direct Flow prosthesis fits into the armamentarium of TAVR prostheses...

Transcatheter aortic valve replacement (TAVR) was designed to treat elderly patients with severe aortic stenosis at high risk for surgery, and is most commonly performed with retrograde approach through femoral arteries. However, in up to 30% of cases, it is either not possible to use this access route or it is considered to have high risk of vascular injury. Alternative approaches have been described for patients with no suitable femoral access: trans-subclavian, transaortic, or direct aortic access; however, since the introduction of new valves deployed with low-profile delivery systems, another alternative transcatheter approach has been discovered...

AIMS: The aim of this study was to examine the short- and medium-term outcomes of transcatheter aortic valve replacement (TAVR) with the self-expanding and repositionable Portico valve (St. Jude Medical, St. Paul, MN, USA). METHODS AND RESULTS: A total of 57 patients underwent TAVR with the Portico valve between March 2012 and August 2014, representing the first-in-human experience and the entire early experience in Canada. Patients were followed up at 30 days and one year with repeat echocardiography and clinical review...

AIMS: Concomitant severe calcific aortic and mitral stenosis is a relatively uncommon but very challenging valvular heart disease to manage. We sought to evaluate the feasibility of a fully percutaneous approach to replace both stenotic native mitral and aortic valves using SAPIEN 3 valves. METHODS AND RESULTS: An 87-year-old woman with chronic kidney disease stage 3, pul-monary hypertension, chronic obstructive pulmonary disease, a permanent pacemaker, and atrial fibrillation was referred with Class III heart failure symptoms...

OBJECTIVES: The aim of this study was to describe the incidence and clinical impact of left atrial appendage thrombus (LAAT) in a population referred for transcatheter aortic valve replacement (TAVR) and to examine the role of cardiac computed tomography (CCT) in the diagnosis of LAAT. BACKGROUND: Atrial fibrillation is common in patients undergoing TAVR. Embolization of LAAT is a potential mechanism of periprocedural stroke. The incidence and clinical impact of LAAT in a TAVR cohort have not been reported, and the optimal method for diagnosing LAAT remains unclear...

OBJECTIVES: This study sought to explore the impact of balloon post-dilation (BPD) on outcomes in the CoreValve US Clinical Trials. BACKGROUND: BPD following transcatheter aortic valve replacement (TAVR) has been used in selected cases to optimize hemodynamic results. METHODS: Procedural details of 3,532 patients were examined to determine whether BPD was performed after self-expanding TAVR. "Best practice" guidelines recommended BPD for treatment of suboptimal intraprocedural valve function, primarily manifested by moderate or severe residual aortic regurgitation (AR)...

OBJECTIVES: Leaflet thrombosis following transcatheter aortic valve replacement (TAVR) and valve-in-valve (ViV) procedures has been increasingly recognized. However, the factors affecting the post-TAVR/ViV thrombosis are not fully understood. This study aimed to investigate the effect of the geometric confinement of transcatheter aortic valve (TAV) on blood residence time (BRT) on the TAV leaflets and in turn on the post-TAVR valve thrombosis. METHODS: Two computational models, representing a surgical bioprosthesis and a TAV, were developed to study the effect of the geometric confinement on BRT on the leaflets in ViV setting/TAVR Intra-annular positioning...
