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.

Assessment of the MANTA closure device in real-life transfemoral transcatheter aortic valve replacement: A single-centre observational study.

Background: Vascular complications increase morbidity and mortality in transcatheter aortic valve replacement (TAVR). Data involving suture-based percutaneous vascular closure devices (VCDs) have been extensive. Although promising, data regarding the efficacy and safety of the MANTA VCD (Teleflex) are scarce.

Sodium Chloride Physiological Saline Solution Versus Water Preparations Injectable in the Use of Shockwave Intravascular Lithotripsy: A Single-Center Experience.

Background: Shockwave intravascular lithotripsy (IVL) coronary system is a very useful new technology for severely calcified coronary artery plaques before percutaneous coronary intervention (PCI). The device uses a semi-compliant low-pressure balloon, integrated into a sterile catheter, to deliver by vaporizing fluid an expanding bubble that generates high-pressure ultrasonic energy by waves that create multiplane longitudinal micro-macro fractures in calcified plaques, which facilitate optimal stent placement and expansion, and luminal gain.

Methods: The use of Shockwave IVL coronary system in our cardiac catheterization laboratory (Cath lab) at the "Clinique Saint-Hilaire" in Rouen, France, started in March 2019, with 42 procedures performed since this date: two patients in 2019, two patients in 2020, seven patients in 2021, 23 patients in 2022, and eight patients since the beginning of 2023.

A prospective study comparing short versus standard dual antiplatelet therapy in patients with acute myocardial infarction: design and rationale of the TARGET-FIRST trial.

Based on the latest knowledge and technological advancements, it is still debatable whether a modern revascularisation approach in the setting of acute myocardial infarction (AMI), including complete revascularisation (in patients with significant non-culprit lesions) with newer-generation highly biocompatible drug-eluting stents, requires prolonged dual antiplatelet therapy (DAPT). TARGET-FIRST (ClinicalTrials.gov: NCT04753749) is a prospective, open-label, multicentre, randomised controlled study comparing short (one month) DAPT versus standard (12 months) DAPT in a population of patients with non-ST/ST-segment elevation myocardial infarction, completely revascularised at index or staged procedure (within 7 days), using Firehawk, an abluminal in-groove biodegradable polymer rapamycin-eluting stent.

Prospective, single-centre evaluation of the safety and efficacy of percutaneous coronary interventions following a decision tree proposing a no-stent strategy in stable patients with coronary artery disease (SCRAP study).

Aim: We evaluated a decision algorithm for percutaneous coronary interventions (PCI) based on a no-stent strategy, corresponding to a combination of scoring balloon angioplasty (SCBA) and drug-coated balloon (DCB), as a first line approach. Stents were used only in unstable patients, or in case of mandatory bailout stenting (BO-stent).

Methods: From April 2019 to March 2020, 984 consecutive patients, including 1922 lesions, underwent PCI.

ACURATE neo™ aortic valve implantation via carotid artery access: first case report.

Background: The ACURATE neo™ transcatheter heart valve (Boston Scientific, Marlborough, Massachusetts) is predominantly implanted via femoral access. Transcarotid use of this prothesis has never been reported.

Case Presentation: We present the case of an 89-year-old woman referred to us for a transcatheter aortic valve replacement (TAVR).

Incidence, delays, and outcomes of STEMI during COVID-19 outbreak: Analysis from the France PCI registry.

Objectives: The aim of this study was to assess the impact of the coronavirus disease 2019 (COVID-19) outbreak on incidence, delays, and outcomes of ST-elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (PPCI) in France.

Methods: We analyzed all patients undergoing PPCI <24 hours STEMI included in the prospective France PCI registry. The 2 groups were compared on mean monthly number of patients, delays in the pathway care, and in-hospital major adverse cardiac events (MACE: death, stent thrombosis, myocardial infarction, unplanned coronary revascularization, stroke, and major bleeding).

Optical coherence tomography to guide percutaneous coronary intervention of the left main coronary artery: the LEMON study.

Background: Intravascular ultrasound (IVUS)-guided PCI improves the prognosis of left main stem (LMS) PCI and is currently recommended by international guidelines. Although OCT resolution is greater than that of IVUS, this tool is not yet recommended in LMS angioplasty due to the absence of data.

Aims: This pilot study aimed to analyse the feasibility, safety and impact of OCT-guided LMS PCI.

Objectives: This study investigated whether left ventricular (LV) stimulation via a guidewire-reduced procedure duration while maintaining efficacy and safety compared with standard right ventricular (RV) stimulation.

Background: Rapid ventricular pacing is necessary to ensure cardiac standstill during transcatheter aortic valve replacement (TAVR).

Methods: This is a prospective, multicenter, single-blinded, superiority, randomized controlled trial.

Paclitaxel Drug-Coated Balloon After Bare-Metal Stent Implantation, an Alternative Treatment to Drug-Eluting Stent in High Bleeding Risk Patients (The Panelux Trial).

Background: Prolonged dual-antiplatelet therapy (DAPT) in high bleeding risk (HBR) patients undergoing percutaneous coronary intervention can be challenging. We assessed the clinical safety of bare-metal stent (BMS) implantation followed by drug-coated balloon (DCB) treatment in HBR patients for whom drug-eluting stent implantation could be problematic in maintaining low ischemic event rate without increasing hemorrhagic events.

Methods: The study included patients with at least 1 de novo lesion who were either under long-term anticoagulant treatment or required semi-urgent non-coronary intervention.

Background: Transcatheter aortic valve implantation (TAVI) is recommended in patients with severe aortic stenosis that is either inoperable or at high-risk for surgical valve replacement.

Aims: To evaluate trends in the feasibility and safety of transfemoral TAVI over the past 4 years.

Methods: Between 2010 and 2013, all consecutive patients undergoing TAVI in our institution were included in a prospective registry.

Feasibility and safety of early discharge after transfemoral transcatheter aortic valve implantation with the Edwards SAPIEN-XT prosthesis.

There is currently no consensus on the duration of hospitalization required after transfemoral transcatheter aortic valve implantation (TAVI). We report the feasibility and safety of early discharge after TAVI with the Edwards SAPIEN-XT prosthesis. From 2009 to 2013, 337 patients underwent transfemoral TAVI with the Edwards SAPIEN-XT prosthesis using local anesthesia and were discharged home either early (≤3 days, Early Discharge group, n = 121) or after 3 days (Late Discharge group, n = 216).

Objectives: To compare image quality and radiation dose of pre-transcatheter aortic valve implantation (TAVI) aortoiliofemoral CT angiography (AICTA) provided by standard vs. dual-energy mode with reduced iodine load protocols.

Methods: One hundred and sixty-one patients underwent a two-step CTA protocol before TAVI including cardiac CTA with injection of 65 mL of iodinated contrast agent (ICA), immediately followed by AICTA.

Does residual aortic regurgitation after transcatheter aortic valve implantation increase mortality in all patients? The importance of baseline natriuretic peptides.

Background: Aortic regurgitation (AR) is an important complication of transcatheter aortic valve implantation (TAVI) and even moderate AR is associated with increased mortality after TAVI. The association with decreased survival is unclear. We aimed to analyse the impact of AR after TAVI as a function of baseline NT-proBNP.

Balloon aortic valvuloplasty in the era of transcatheter aortic valve replacement: acute and long-term outcomes.

Background: The use of balloon aortic valvuloplasty (BAV) has resurged since the development of transcatheter aortic valve replacement (TAVR). The aim of our study was to determine the procedural and long-term outcomes of patients treated by BAV in the early TAVR era.

Methods: From 2005 to 2008, 323 consecutive patients presenting with severe aortic stenosis were treated by BAV in our institution.

Expandable sheath for transfemoral transcatheter aortic valve replacement: procedural outcomes and complications.

Aims: It is currently unknown whether the expandable sheath (e-sheath) for transfemoral Edwards transcatheter aortic valve replacement (TAVR) has a lower rate of access complications than the 18/19F fixed size sheath (f-sheath). Our aim was to compare the incidence of procedural complications when using f-sheath vs. e-sheath during TAVR.

Comparison of two antiplatelet therapy strategies in patients undergoing transcatheter aortic valve implantation.

Dual antiplatelet therapy is commonly used in patients undergoing transcatheter aortic valve implantation (TAVI), but the optimal antiplatelet regimen is uncertain and remains to be determined. The objective of this study was to compare 2 strategies of antiplatelet therapy in patients undergoing TAVI. A strategy using monoantiplatelet therapy (group A, n = 164) was prospectively compared with a strategy using dual antiplatelet therapy (group B, n = 128) in 292 consecutive patients undergoing TAVI.

Performance analysis of EuroSCORE II compared to the original logistic EuroSCORE and STS scores for predicting 30-day mortality after transcatheter aortic valve replacement.

The original European System for Cardiac Operative Risk Evaluation (EuroSCORE) has been recently updated as EuroSCORE II to optimize its efficacy in cardiac surgery, but its performance has been poorly evaluated for predicting 30-day mortality in patients who undergo transcatheter aortic valve replacement (TAVR). Consecutive patients (n = 250) treated with TAVR were included in this analysis. Transapical access was used in 60 patients, while 190 procedures were performed using a transfemoral approach.

Incidence, predictors and impact of bleeding after transcatheter aortic valve implantation using the balloon-expandable Edwards prosthesis.

Objectives: To evaluate the incidence, predictors and impact of bleeding after transcatheter aortic valve implantation (TAVI).

Design: Single-centre prospective observational study.

Setting: Charles Nicolle University Hospital, Rouen, France.

Transfemoral aortic valve replacement with the Edwards SAPIEN and Edwards SAPIEN XT prosthesis using exclusively local anesthesia and fluoroscopic guidance: feasibility and 30-day outcomes.

Objectives: The authors report the feasibility and 30-day outcomes of transfemoral aortic valve replacement (TAVR), using the Edwards SAPIEN (Edwards Lifesciences, Irvine, California) and Edwards SAPIEN XT (Edwards Lifesciences) prosthesis, implanted using exclusively local anesthesia and fluoroscopic guidance.

Background: Transfemoral TAVR is often managed with general anesthesia. However, a simplified percutaneous approach using local anesthesia has become more popular because it offers multiple advantages in an elderly and fragile population.

[Selection of patients for transcatheter aortic valve implantation].

A good selection of patients is a crucial step before transcatheter aortic valve implantation (TAVI) in order to select the good indications and choose the access route. TAVI should be considered only in patients with symptomatic severe aortic stenosis and either contraindication or high surgical risk. Indication for TAVI should be discussed in a multidisciplinary team meeting.
