Although occlusion of the coronary arteries during transcatheter aortic valve replacement is rare, the mortality is high. In this review, we discuss the prevention and management of this complication. Occlusion of coronary ostia is a very rare, but serious, complication of transcatheter aortic valve replacement (TAVR). Although reported as only occurring in <1% of TAVR cases, it carries a high risk of fatality, with some series reporting a mortality rate as high as 40%. We present the management of an occluded left coronary artery after a self-expanding TAVR, and review the incidence, prevention, and management of this complication...

OBJECTIVES: We sought to assess angiographic, echocardiographic and hemodynamic grading of paravalvular leakage (PVL) after transcatheter aortic valve implantation (TAVI) with respect to prediction of 1-year mortality. BACKGROUND: Meaningful criteria for the severity of PVL are needed to allow intraprocedural guidance and patient management after TAVI. METHODS: We pooled the prospective TAVI databases of 2 German centers. During TAVI, PVL was assessed angiographically and by the aortic regurgitation index (ARI)...

OBJECTIVES: Compare final morphology of self-expanding and balloon-expandable prosthesis and association with paravalvular regurgitation (PVR). BACKGROUND: PVR after transcatheter aortic valve replacement (TAVR) remains a frequent complication. A better understanding of the prosthesis geometry may be important to improve selection of the best device for each case and possibly reduce the rates of PVR. METHODS: Retrospective study including patients consecutively submitted to transcatheter aortic valve replacement: August/2007-October/2016...

Despite the technical advancements in transcatheter aortic valve implantation (TAVI), this procedure in patients with peripheral artery disease remains challenging and requires a patient-tailored management by the Heart Team. In-depth assessment of the patient's vascular anatomy is of utmost importance for the management of TAVI procedures with the aim to use the less invasive approach according to the specific patient characteristics. The trans-subclavian approach should be the preferred option in patients with femoral arterial disease undergoing TAVI; however, self-expandable valves have potential limitations, as in case of ascending aorta dilation and high implantation...

BACKGROUND: Transcatheter mitral valve replacement (TMVR) is a potential therapy for patients with symptomatic, severe mitral regurgitation (MR). The feasibility of this therapy remains to be defined. OBJECTIVE: We report our early experience with TMVR using a new valve system. METHODS: The valve is a self-expanding, nitinol valve with bovine pericardial leaflets that is placed using a transapical delivery system. Patients with symptomatic MR who were deemed high or extreme risk by the local heart teams were enrolled in a global pilot study at 14 sites (U...

BACKGROUND: Iliofemoral arterial disease can preclude transfemoral (TF) transcatheter aortic valve replacement (TF-TAVR). Transthoracic access by direct aortic or a transapical approach imparts a greater risk of complications and death than TF access. We hypothesized that subclavian/axillary arterial (SCA) access offers equivalent risks and outcomes as TF access. METHODS: The outcomes of 202 patients from the CoreValve (Medtronic, Minneapolis, MN) United States Pivotal Trial Program treated with SCA access were propensity matched with patients treated with TF access and analyzed...

BACKGROUND: Although transcatheter aortic valve implantation (TAVI) is a steadily expanding treatment for the pathology of the aortic valve, its role in the replacement of native aortic valves following valve-sparing surgery has not been investigated. METHODS: Among 150 patients who underwent TAVI at the authors' institution, three (2%) had a failed valve-sparing operation. The in-hospital outcome, mid-term mortality, and valvular function of the three patients were evaluated retrospectively...

Transcatheter aortic valve replacement (TAVR) has become standard therapy for patients with severe aortic stenosis who are deemed at least intermediate risk for surgical valve replacement. Over the past decade, several technological advances have taken place to improve the quality and safety of these devices. The current commercially available valves are broadly grouped into balloon expandable and self-expandable valves. The latest iteration of the self-expandable valve is Medtronic's repositionable valve known as the Evolut PRO system...

An 87-year-old female with symptomatic severe aortic stenosis underwent transcatheter valve replacement (TAVR) via the transfemoral approach with a 29mm self-expanding device. Moderate to severe paravalvular regurgitation led to the development of congestive heart failure and hospital readmission 1 month following TAVR. A second 29mm valve was placed to abolish the paravalvular regurgitation. Routine follow-up computed tomography (CT) imaging demonstrated leaflet thickening and decreased leaflet mobility suggesting valve thrombosis, despite adherence to Factor Xa inhibitor...

Transcatheter aortic valve implantation (TAVI) has emerged as a viable treatment modality for patients with severe aortic valve stenosis and multiple co-morbidities. More recent indications include the use of transcatheter heart valves (THV) to treat degenerated bioprosthetic surgical heart valves (SHV), which are failing due to stenosis or regurgitation. Valve-in-valve (VIV) procedures in the aortic position have been performed with a variety of THV devices, although the balloon-expandable SAPIEN valve platform (Edwards Lifesciences Ltd, Irvine, CA, USA) and self-expandable CoreValve platform (Medtronic Inc...

The encouraging results of the PARTNER 2 (Placement of AoRtic TraNscathetER Valves 2) trial led to the approval of transcatheter aortic valve replacement (TAVR) in intermediate-surgical-risk patients. Recently, the SURTAVI (SUrgical Replacement and Transcatheter Aortic Valve Implantation) investigators demonstrated the feasibility of TAVR with self-expanding valves in intermediate-risk patients. The focus has now shifted to clinical trials comparing TAVR to surgery in low-surgical-risk populations with a goal to expand TAVR to all-risk patients...

AIMS: The XELTIS aortic valve leaflets are made from a bioabsorbable supramolecular polymer that guides the tissue to restoring itself. It is mounted on a self-expandable nitinol frame that includes three feelers and a native leaflet clipping mechanism. We sought to investigate the acute valve performance in a preclinical setting. METHODS AND RESULTS: In 33 sheep, 26 mm XELTIS aortic valve were transapically implanted in a 23 mm native annulus. Aortography (analysable, n=28) and echocardiography (analysable, n=20) were acquired immediately after implantation of the XELTIS aortic valve to assess the acute device performance...
