BACKGROUND: The aim of this study was to determine the influence of an elliptic annulus on acute device success rates following self-expanding (SE) transcatheter aortic valve replacement (TAVR) vs. balloon-expandable (BE) TAVR.Methods and Results:Outcomes were assessed using Valve Academic Research Consortium-2 definitions. Aortic annulus ratio (AAR) was measured as short axis diameter/long axis diameter. Mean AAR was 0.81±0.06. Patients were therefore divided into 2 groups: AAR <0...

BACKGROUND: Subclinical leaflet thrombosis of bioprosthetic aortic valves after transcatheter valve replacement (TAVR) and surgical aortic valve replacement (SAVR) has been found with CT imaging. The objective of this study was to report the prevalence of subclinical leaflet thrombosis in surgical and transcatheter aortic valves and the effect of novel oral anticoagulants (NOACs) on the subclinical leaflet thrombosis and subsequent valve haemodynamics and clinical outcomes on the basis of two registries of patients who had CT imaging done after TAVR or SAVR...

BACKGROUND: The clinical significance of left ventricular (LV) diastolic function (DF) improvement after transcatheter aortic valve implantation (TAVI) is not fully elucidated. We sought to investigate the long-term clinical and hemodynamic effects of post-TAVI DF improvement and to identify its determinants.Methods and Results:Clinical and serial echocardiographic data before and after TAVI were retrospectively reviewed together with measurement of mitral annular displacement (MAD) representing longitudinal myocardial function in 98 patients with severe aortic stenosis and ejection fraction >55%...

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...

Severe device landing zone calcification (DLZ-CA) predicted paravalvular leak (PVL) and post-dilatation (PD) after transcatheter aortic valve implantation (TAVI). The aim of this study was to determine the influence of DLZ-CA on PVL or PD rates after SAPIEN XT (XT) versus CoreValve (CV).We analyzed patients undergoing TAVI who had severe DLZ-CA. Severe DLZ-CA defined the upper left ventricular outflow tract calcification; the cross-sectional region 2 mm inferior to the annular plane. PVL was evaluated at 30days using transthoracic echocardiography...

AIMS: Calcified aortic stenosis (AS) and mitral annular calcification (MAC) have certain similar etiology and pathophysiological mechanisms. MAC is frequently encountered in pre-procedural computed tomography (CT) imaging of patients that undergo transcatheter aortic valve replacement (TAVR), but its prognostic implications for these patients have not been thoroughly investigated. This study sought to evaluate the prevalence of MAC among patients with severe AS and to assess the clinical implications of MAC on these patients during and following TAVR...

BACKGROUND: Neurological complications after transcatheter aortic valve replacement (TAVR) may be reduced with transcatheter cerebral embolic protection (TCEP). OBJECTIVES: This study evaluated the safety and efficacy of TCEP during TAVR. METHODS: Nineteen centers randomized 363 patients undergoing TAVR to a safety arm (n = 123), device imaging (n = 121), and control imaging (n = 119). The primary safety endpoint consisted of major adverse cardiac and cerebrovascular events (MACCE) at 30 days, and the primary efficacy endpoint was reduction in new lesion volume in protected brain territories on magnetic resonance imaging scans at 2 to 7 days...

OBJECTIVES: Aortic valve preparation with balloon aortic valvuloplasty (BAV) has been previously considered mandatory during transcatheter aortic valve implantation (TAVI) procedures. BAV-inherent risks including stroke, conduction abnormalities, and reduced device profile size established the rationale for safe valve deployment without the need for aggressive valve preparation. We investigate the feasibility and safety of performing Sapien 3 (S3; Edwards Lifesciences) balloon-expandable TAVI with moderate or without predilation (PD)...

Symptomatic transcatheter heart valve (THV) thrombosis is noted in up to 1% of patients after transcatheter aortic valve replacement. Recently, hypoattenuated leaflet thickening and reduced leaflet motion of bioprosthetic aortic valves associated with normal transvalvular gradients (and possibly related to subclinical leaflet thrombosis) have been reported. While trans-thoracic echocardiography is a useful initial screening imaging modality for the detection of symptomatic THV thrombosis associated with elevated transvalvular gradients, it has limited utility in the detection of subclinical THV thrombosis...

IMPORTANCE: Limited data exist on clinical characteristics and outcomes of patients who had infective endocarditis after undergoing transcatheter aortic valve replacement (TAVR). OBJECTIVE: To determine the associated factors, clinical characteristics, and outcomes of patients who had infective endocarditis after TAVR. DESIGN, SETTING, AND PARTICIPANTS: The Infectious Endocarditis after TAVR International Registry included patients with definite infective endocarditis after TAVR from 47 centers from Europe, North America, and South America between June 2005 and October 2015...

AIMS: The Valve Academic Research Consortium (VARC) recommendations were devised to standardise clinical endpoint definitions which best reflect the safety and efficacy of transcatheter aortic valve implantation (TAVI). The categorisation of vascular complications (VC) is greatly affected by the definition, but the impact of its change is unclear. We sought to compare VC between VARC-1 and VARC-2 definitions as a predictor for survival. METHODS AND RESULTS: A series of 376 patients undergoing TAVI by the transfemoral or transapical approach was studied...

OBJECTIVES: The aim of this study was to evaluate the impact of increased aortic angulation (AA) on acute procedural success following transcatheter aortic valve replacement (TAVR). BACKGROUND: The degree of angulation between the aorta and the heart can make accurate positioning of the bioprosthesis during TAVR more demanding, particularly in instances of an extremely angulated or horizontal aortic root. Nonetheless, there are limited data on the impact of AA on the acute success of TAVR...

OBJECTIVES: This study sought to evaluate transcatheter aortic valve replacement (TAVR) in bicuspid aortic valve (BAV) aortic stenosis (AS), with a particular emphasis on TAVR-directed bicuspid aortic valve imaging (BAVi) of morphological classification. BACKGROUND: TAVR has been used to treat BAV-AS but with heterogeneous outcomes and uncertainty regarding the relevance of morphology. METHODS: In 14 centers in the United States, Canada, Europe, and Asia, 130 BAV-AS patients underwent TAVR...

BACKGROUND: Significant paravalvular leak (PVL) occurs in up to 13% of patients after transcatheter aortic valve replacement (TAVR) with a balloon-expandable bioprosthesis. Transcatheter PVL repair has emerged as a less invasive alternative for this problem. OBJECTIVES: The aim of this study was to evaluate the safety, feasibility, and clinical outcomes of transcatheter PVL repair after TAVR with balloon-expandable valve. METHODS: We retrospectively identified 15 patients who underwent 16 PVL repair procedures after the TAVR at our center...

AIMS: Prosthesis-patient mismatch (PPM) after transcatheter aortic valve replacement (TAVR) leads to increased mortality. However, its peri-procedural determinants remain unknown. We investigated geometric changes in aortic annulus (AoA) and left ventricular outflow tract (LVOT) during TAVR by three-dimensional transoesophageal echocardiography (3D-TEE) and its association with post-procedural PPM. METHODS AND RESULTS: A total of 131 patients with severe aortic stenosis underwent intraprocedural 3D-TEE during balloon-expandable TAVR...

Several clinical variables have been identified as predictors of clinical outcome after transcatheter aortic valve implantation (TAVI). Nonetheless, there is limited and contradictive data on the impact of diabetes mellitus (DM) on the prognosis of patients who undergo TAVI. We aimed to investigate the clinical characteristics and the early and midterm outcomes after TAVI according to DM status. From 802 consecutive patients who underwent TAVI, we compared 548 patients with no DM to 254 patients with diabetes (177 orally treated and 77 insulin treated)...
