Assessment of chronical total occlusions management in France: The ENCOCHE Registry, a prospective, multicentric study.

Background: Coronary chronic total occlusions (CTO) are frequent, and coronary angioplasty has been increasingly used in recent years for lesion revascularisation. However, to date, no dedicated multicentric prospective study is available in France.

Aim: To describe the characteristics of CTO patients and to assess current treatment strategies in French catheterisation laboratory practice.

Directional atherectomy with antirestenotic therapy for the treatment of no-stenting zones.

Endovascular treatment for peripheral artery occlusive disease carries unresolved problem of restenosis. Treatment modalities in areas of high mechanical stress like popliteal artery and common femoral artery remains challenging. New-generation devices improved the results of stent therapy in this anatomical territory, but could impact on future surgical options if they are needed.

Bicuspid Aortic Valve Anatomy and Relationship With Devices: The BAVARD Multicenter Registry.

Background: Sizing for transcatheter aortic valve implantation in bicuspid aortic valves (BAV) remains controversial.

Methods And Results: The aim of the BAVARD (Bicuspid Aortic Valve Anatomy and Relationship With Devices) retrospective registry is to capture the sizing ratios used for transcatheter aortic valve implantation in BAV and analyze the second-generation prostheses geometry postimplantation. About 101 patients with BAV along with available pre- and post-transcatheter aortic valve implantation multidetector computed tomography were compared with 88 tricuspid aortic valves (TAV) patients.

What are the remaining limitations of TAVI?

Transcatheter aortic valve implantation (TAVI) is a recognized therapy for patients with symptomatic severe aortic stenosis (AS). TAVI is superior compared to medical therapy as for mortality in extreme-risk patients, is non-inferior or superior to surgery in high-risk patients and non-inferior to surgery in intermediate-risk patients. However, several limitations affect outcomes after TAVI.

Aortic valve anatomy and outcomes after transcatheter aortic valve implantation in bicuspid aortic valves.

This original clinical research study id focused on description of baseline anatomy and outcomes after transcatheter aortic valve implantation (TAVI) in patients presenting with severe aortic stenosis (AS) and bicuspid aortic valve (BAV). We compared this BAV population with a population of patients with AS and tricuspid aortic valves after a propensity score matching developed by a multivariate logistic regression according to a non-parsimonious approach. Baseline anatomical characteristics were obtained by transthoracic echocardiography (TTE) and multi-sliced computed tomography (MSCT) and compared by chi-square and t-student tests.

Impact of Pre-Existing Prosthesis-Patient Mismatch on Survival Following Aortic Valve-in-Valve Procedures.

Objectives: The aim of this study was to determine whether the association of small label size of the surgical valve with increased mortality after transcatheter valve-in-valve (ViV) implantation is, at least in part, related to pre-existing prosthesis-patient mismatch (PPM) (i.e., a bioprosthesis that is too small in relation to body size).

Incidence and outcomes of emergent cardiac surgery during transfemoral transcatheter aortic valve implantation (TAVI): insights from the European Registry on Emergent Cardiac Surgery during TAVI (EuRECS-TAVI).

Aims: Life-threatening complications occur during transcatheter aortic valve implantation (TAVI) which can require emergent cardiac surgery (ECS). Risks and outcomes of patients needing ECS during or immediately after TAVI are still unclear.

Methods And Results: Incidence, risk factors, management, and outcomes of patients requiring ECS during transfemoral (TF)-TAVI were analysed from a contemporary real-world multicentre registry.

Non-Vitamin K Oral Anticoagulants for Stroke Prevention in Special Populations with Atrial Fibrillation.

Atrial fibrillation (AF) is associated with an increased risk of ischemic stroke or systemic embolism compared with normal sinus rhythm. These strokes may efficiently be prevented in patients with risk factors using oral anticoagulant therapy, with either vitamin K antagonists (VKAs) or non-vitamin K antagonist oral anticoagulants (NOACs) (i.e.

Oral anticoagulation, stroke and thromboembolism in patients with atrial fibrillation and valve bioprosthesis. The Loire Valley Atrial Fibrillation Project.

Vitamin K antagonists are currently recommended in patients with 'valvular' atrial fibrillation (AF), e. g. those having mitral stenosis or artificial heart valves.

How to define valvular atrial fibrillation?

Atrial fibrillation (AF) confers a substantial risk of stroke. Recent trials comparing vitamin K antagonists (VKAs) with non-vitamin K antagonist oral anticoagulants (NOACs) in AF were performed among patients with so-called "non-valvular" AF. The distinction between "valvular" and "non-valvular" AF remains a matter of debate.

Prognostic value of CHA2DS2-VASc score in patients with 'non-valvular atrial fibrillation' and valvular heart disease: the Loire Valley Atrial Fibrillation Project.

Aims: The CHA2DS2VASc score is a clinical risk stratification tool which estimates the risk of stroke and thromboembolism in non-valvular atrial fibrillation (AF). We aimed to establish the value of this score for risk evaluation in patients with non-valvular AF and valvular heart disease.

Methods And Results: Among 8053 patients with non-valvular AF (ESC guidelines definition), patients were categorized into Group 1 (no valve disease, n = 6851; 85%) and Group 2 (valve disease with neither rheumatic mitral stenosis nor valve prothesis, n = 1202; 15%).
