What Do I Do if the Valve Don't Pass? Use a Snare Catheter!

We report a case of a complex transcatheter aortic valve implantation (TAVI) complicated by severe calcifications, which prevented the delivery system from advancing through the aortic valve. To address this challenge, we employed an innovative solution using a Snare catheter. This approach enabled stabilization and guidance of the delivery system, facilitating the crossing of the calcified obstruction and the successful completion of the procedure.

Spontaneous coronary artery dissection 'storm' in post-partum: a case report.

Background: Spontaneous coronary artery dissection (SCAD) remains a rare form of acute coronary syndrome (ACS) in young women. It is not always easy to diagnose and its management can be complex, particularly in the case of severe forms.

Case Summary: A 29-year-old Mahorese woman presented with non-ST-elevation acute coronary syndrome 72 h after vaginal delivery of an uncomplicated twin pregnancy.

Stent Underexpansion Is an Underestimated Cause of Intrastent Restenosis: Insights From RESTO Registry.

Background: Despite improvement in devices, in-stent restenosis remains a frequent and challenging complication of percutaneous coronary interventions.

Methods And Results: The RESTO (Morphological Parameters of In-Stent Restenosis Assessed and Identified by OCT [Optical Coherence Tomography]; study NCT04268875) was a prospective multicenter registry including patients presenting with coronary syndromes related to in-stent restenosis. All patients underwent preintervention OCT analysis, which led to analysis of in-stent restenosis phenotype, number of strut layers, and presence of stent underexpansion.

Ventilation strategies in cardiogenic shock: insights from the FRENSHOCK observational registry.

Background: Despite scarce data, invasive mechanical ventilation (MV) is widely suggested as first-line ventilatory support in cardiogenic shock (CS) patients. We assessed the real-life use of different ventilation strategies in CS and their influence on short and mid-term prognosis.

Methods: FRENSHOCK was a prospective registry including 772 CS patients from 49 centers in France.

[Endocoronary imaging contribution in iatrogenic dissection management].

Iatrogenic coronary dissections are rare but potentially serious. Their management is complex, particularly if the dissection occurs without an angioplasty guide in the arterial lumen. In this context, angiography alone is insufficient, and endocoronary imaging is essential (using optical coherence or IVUS) to guide angioplasty when necessary (guide in the true lumen, coverage of the tear).

Cardiogenic shock and infection: A lethal combination.

Background: Cardiogenic shock and sepsis are severe haemodynamic states that are frequently present concomitantly, leading to substantial mortality. Despite its frequency and clinical significance, there is a striking lack of literature on the outcomes of combined sepsis and cardiogenic shock.

Methods: FRENSHOCK was a prospective registry including 772 patients with cardiogenic shock from 49 centres.

Safety and Efficacy of Mini-Invasive Left Atrial Appendage Closure: A Propensity-Score Analysis.

Background: Left atrial appendage closure (LAAC) for prevention of stroke is validated in patients with nonvalvular atrial fibrillation (NVAF) contraindicated to oral anticoagulation. General anaesthesia (GA) is often used for procedural guidance by transesophageal echocardiography (TEE); however, its use may be challenging in some patients. The aim of the study was to evaluate the safety and the midterm efficacy of a mini-invasive LAAC strategy using micro-TEE under procedural sedation.

Sex disparities in cardiogenic shock: Insights from the FRENSHOCK registry.

Background: Cardiogenic shock (CS) is the most severe form of acute heart failure. Discrepancies have been reported between sexes regarding delays, pathways and invasive strategies in CS complicating acute myocardial infarction. However, effect of sex on the prognosis of unselected CS remains controversial.

Optimal Heart Failure Medical Therapy and Mortality in Survivors of Cardiogenic Shock: Insights From the FRENSHOCK Registry.

Background: The effects of pharmacological therapy on cardiogenic shock (CS) survivors have not been extensively studied. Thus, this study investigated the association between guideline-directed heart failure (HF) medical therapy (GDMT) and one-year survival rate in patients who are post-CS.

Methods And Results: FRENSHOCK (French Observatory on the Management of Cardiogenic Shock in 2016) registry was a prospective multicenter observational survey, conducted in metropolitan French intensive care units and intensive cardiac care units.

Transfemoral versus trans-subclavian access in transcatheter aortic valve implantation using self-expandable valve: A propensity-matched comparison.

Background: Transcatheter aortic valve implantation is unfeasible for 10-15% of patients using the conventional transfemoral approach. Other alternative approaches, such as the subclavian approach, have emerged, with no clear recommendation indicating the superiority of one technique over another.

Aim: To compare the 1-month mortality and postprocedural outcomes of patients undergoing transcatheter aortic valve implantation using a self-expandable valve via transfemoral and subclavian access.

[French National registry of spontaneous coronary artery dissections : ''DISCO registry''].

Aim: Spontaneous coronary artery dissection (SCAD) is a form of acute coronary syndrome (ACS). The aim of this registry is to assess the clinical and angiographic features of SCAD, to describe the therapeutic management and prognosis, and to identify links with other vascular diseases.

Method: From 2016 to 2018, 424 patients with a diagnosis of SCAD were included prospectively and retrospectively in 51 French cardiology centres.

One-year outcomes in cardiogenic shock triggered by supraventricular tachycardia: an analysis of the FRENSHOCK multicenter prospective registry.

Background: Cardiogenic shock (CS) is the most severe form of heart failure (HF), resulting in high early and long-term mortality. Characteristics of CS secondary to supraventricular tachycardia (SVT) are poorly reported. Based on a large registry of unselected CS, we aimed to compare 1-year outcomes between SVT-triggered and non-SVT-triggered CS.

Cardiogenic Shock in Idiopathic Dilated Cardiomyopathy Patients: Red Flag for Myocardial Decline.

Idiopathic dilated cardiomyopathy (IDCM) is one of the most common forms of nonischemic cardiomyopathy worldwide, possibly leading to cardiogenic shock (CS). Despite this heavy burden, the outcomes of CS in IDCM are poorly reported. Based on a large registry of unselected CS, our aim was to shed light on the 1-year outcomes after CS in patients with and without IDCM.

Contribution of the Optical Coherence Tomography in Calcified Lesions.

Coronary artery calcification is a complex process found predominantly in the elderly population. Coronary angiography frequently lacks sensitivity to detect, evaluate and quantify these lesions. Yet calcified lesions are considered stable, it remains associated with a higher rate of peri procedural complications during percutaneous coronary intervention (PCI) including an increased risk of stent under expansion and struts mal apposition leading to poor clinical outcome.

One-year outcomes in cardiogenic shock triggered by ventricular arrhythmia: An analysis of the FRENSHOCK multicenter prospective registry.

Background: Cardiogenic shock (CS) is a life-threatening condition carrying poor prognosis, potentially triggered by ventricular arrhythmia (VA). Whether the occurrence of VA as trigger of CS worsens the prognosis compared to non-VA triggers  remains  unclear.  The  aim  of  this  study  was  to  evaluate  1-year  outcomes [mortality, heart transplantation, ventricular assist devices (VAD)] between VA-triggered and non-VA-triggered CS.

Post-Dilatation of New-Generation Self-Expandable Transcatheter Aortic Valves Does Not Increase Atrioventricular Conduction Abnormalities.

The impact that post-dilatation has on the risk of experiencing conduction disorders after post-transcatheter aortic valve replacement with self-expanding valves (SE-TAVR) is unclear. We compared the rate of developing an atrioventricular (AV) high-grade conduction disorder and permanent pacemaker implantation (PPI) in post-TAVR patients undergoing post-dilatation. We enrolled patients with severe symptomatic calcified aortic stenosis (CAS) who were undergoing SE-TAVR between 1 January 2016, and 19 April 2019 at a single French center.

Incidence and management of atrioventricular conduction disorders in new-onset left bundle branch block after TAVI: A prospective multicenter study.

Background: New-onset left bundle branch block (LBBB) is one of the most frequent complications after transcatheter aortic valve implantation (TAVI) and is associated with delayed high degree atrioventricular (AV) block.

Objectives: The objectives of this study were to determine the incidence of AV block in such a population and to assess the performance and safety of a risk stratification algorithm on the basis of electrophysiology study (EPS) followed by implantation of a pacemaker or implantable loop recorder (ILR).

Methods: This was a prospective open-label study with 12-month follow-up.
