OBJECTIVES: : The aim of this study was to prove technical feasibility and document haemodynamic and clinical outcomes of transcatheter aortic valve implantation (TAVI) with the latest generation repositionable and retrievable Lotus™ transcatheter heart valve (THV) without prior balloon-aortic valvuloplasty (BAV). It has been demonstrated for self-expandable and balloon-expandable THV that implantation without prior BAV is not only feasible and safe but also results in lower fluoroscopy times and amounts of contrast agent while yielding non-inferior haemodynamic and clinical outcome...

REVIEW
Caroline Bleakley, Mehdi Eskandari, Mark Monaghan
Transcatheter aortic valve implantation (TAVI) was initially proven as an alternative to valve replacement therapy in those beyond established risk thresholds for conventional surgery. With time the technique has been methodically refined and offered to a progressively lower risk cohort, and with this evolution has come that of the significant imaging requirements of valve implantation. This review discusses the role of transoesophageal echocardiography (TOE) in the current TAVI arena, aligning it with that of cardiac computed tomography, and outlining how TOE can be used most effectively both prior to and during TAVI in order to optimise outcomes...

AIM: The role of transoesophageal echocardiography in cardiac interventional structural procedures is well established and appreciated. However, the need for general anaesthesia (GA) throughout the procedure remains a controversial issue. The aim of the present study is to assess the feasibility and imaging quality of using a transnasal microrobe that allows the usage of conscious sedation in patients that undergo cardiac structural interventional procedures without missing the benefits, guidance and navigation of conventional trans-procedural TEE...

BACKGROUND: Dual antiplatelet therapy (DAPT) is commonly used after transcatheter aortic valve implantation (TAVI); however, the supporting evidence is limited. To determine if aspirin alone is a better alternative to DAPT, we compared the outcomes of patients treated with DAPT or aspirin alone after TAVI.Methods and Results:We analyzed a total of 144 consecutive patients (92 females, mean age 83±6 years) who underwent implantation of a balloon-expandable transcatheter valve (SAPIEN or SAPIEN XT, Edwards Lifesciences)...

OBJECTIVES: We sought to investigate a new angiographic method for aortic regurgitation (AR) severity assessment in the setting of transcatheter aortic valve implantation (TAVI). BACKGROUND: AR after TAVI is common but challenging to quantitate, especially in the cath-lab. METHODS: In 228 patients, AR was quantitated before and after TAVI by echocardiography and by video-densitometric analysis of aortograms. Contrast time-density curves for the aortic root (the reference region) and the left ventricular outflow tract, LVOT were generated...

AIMS: While TAVI is the treatment of choice in patients with aortic stenosis considered inoperable or at high risk, interventional replacement of the mitral valve is still in the preclinical or early clinical phase. Our aim was to report on the first transcatheter double valve replacement into native valves from a transapical access. METHODS AND RESULTS: A 67-year-old, highly symptomatic female patient considered inoperable due to severe calcification of the mitral annulus and comorbidities was scheduled for transcatheter double valve replacement by the local Heart Team...

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...

INTRODUCTION: Aortic stenosis (AS) is more than only a degenerative disease, it could be also an atherosclerotic-like process involving the valve instead of the vessels. Little is known about the relation of arterial stiffness and AS. AIM: We sought to determine wether pulse wave velocity (PWV), is related to AS severity and to the procedures response, both as surgical aortic-valve-replacement (AVR) and trascatheter-aortic-valve-implantation (TAVI). METHODS: 30 patients with severe AS were treated (15 AVR, 15 TAVI)...

AIMS: Quantitative mitral regurgitation (MR) grading remains challenging. This study evaluated the concept of integrating echocardiography and computed tomography for grading MR severity. Specifically, an integrated parameter was developed that combines the true cross-sectional mitral regurgitant orifice area (ROA) assessed with multi-detector row computed tomography (MDCT) with flow data from echocardiography. METHODS AND RESULTS: Systolic MDCT data of 73 patients, referred for transcatheter aortic valve implantation (TAVI) who also had MR, were evaluated...

AIMS: The Edwards Sapien 3 heart valve prosthesis (S3) is commonly used for transcatheter aortic valve implantation (TAVI) and is available in three sizes. To date no data has been published on the effective orifice area (EOA) and the hemodynamic performance of the three different S3 sizes. The aim of this study was to measure the size-specific EOA and hemodynamic performance of the S3 in short-term and 1-year follow-up. METHODS AND RESULTS: One hundred and thirteen consecutive patients treated by TAVI with a S3 prosthesis at the Heart Clinic Zurich between May 2014 and July 2015 were included...

BACKGROUND: Severe aortic stenosis (AS) is a common, serious valve disease in which no effective medical therapy is available and, if not treated by intervention, has a 5-year survival of only 40-60%. Despite the availability of guidelines supporting the effective use of surgical aortic valve replacement (SAVR) or transcatheter aortic valve implantation (TAVI) to treat the majority of these patients, adherence to these guidelines in clinical practice is still unsatisfactory. Several recent studies have emphasised the necessity for improved communication between multidisciplinary teams, with the aim to ensure that severe AS patients receive appropriate treatment...

BACKGROUND: Aortic regurgitation (AR) is a frequent and life-limiting complication after transcatheter aortic valve implantation (TAVI). The study aim was to relate post-TAVI AR, using a self-expandable stent, to detailed baseline anatomical and morphological characteristics of the native aortic valve. METHODS: A total of 82 patients (40 males, 42 females; mean age 80 ± 7 years) who received a Medtronic CoreValve implant was included. Aortic root morphology, aortic annulus and implant size mismatch, implant position, extent of aortic annulus and leaflet calcification, the connected sub-annular calcification volume, and their distribution were quantified based on computed tomography scan analysis...

Thrombosis of transcatheter aortic valve implantation (TAVI) is an uncommon complication that commonly occurs weeks to months following the procedure. Herein are described the details of a patient who presented with a recurrence of symptoms days after intervention with a bioprosthesis thrombosis that was successfully treated with direct oral anticoagulant (DOAC) therapy and resulted in hemodynamic improvement and resolution of symptoms. Whilst a previous trial of DOAC therapy with mechanical valves was stopped due to elevated events in comparison to warfarin, a TAVI valve may be different, and the rapid onset of action and reduced bleeding risk may be beneficial in this patient group...

BACKGROUND: Aortic valve replacement (AVR) is the treatment of choice in patients with severe symptomatic aortic stenosis (AS). Patients with a low left ventricular ejection fraction (LVEF) represent a challenge for evaluation and therapeutic decision. Dobutamine stress echocardiography (DSE) allows the distinction to be made between fixed low-flow/low-gradient (LF/LG) AS and pseudosevere AS. METHODS: Between 2001 and 2014 a retrospective analysis was conducted of patients who underwent DSE to investigate severe AS...
