Outcomes of transcatheter aortic valve implantation for native aortic valve regurgitation.

Background: Large datasets of transcatheter aortic valve implantation (TAVI) for pure aortic valve regurgitation (PAVR) are scarce.

Aims: We aimed to report procedural safety and long-term clinical events (CE) in a contemporary cohort of PAVR patients treated with new-generation devices (NGD).

Methods: Patients with grade III/IV PAVR enrolled in the FRANCE-TAVI Registry were selected.

ECMO Alone Versus ECPELLA in Patients Affected by Cardiogenic Shock: The Multicenter EVACS Study.

The objective was to investigate the outcomes of concomitant venoarterial extracorporeal membrane oxygenation (ECMO) and left ventricular unloading with Impella (ECPELLA) compared with ECMO alone to treat patients affected by cardiogenic shock. Data from patients needing mechanical circulatory support from 4 international centers were analyzed. Of 438 patients included, ECMO alone and ECPELLA were adopted in 319 (72.

Impella for the Management of Ventricular Septal Defect Complicating Acute Myocardial Infarction: A European Multicenter Registry.

Ventricular septal defect (VSD) is a rare but severe complication of myocardial infarction (MI). Temporary mechanical circulatory support (MCS) can be used as a bridge to VSD closure, heart transplantation, or ventricular assist device. We describe the use of Impella device in this context based on a multicenter European retrospective registry (17 centers responded).

Management and outcomes of ventricular septal defects after acute myocardial infarction: A multicenter retrospective study.

Background And Aim: The mortality rate of patients with post-myocardial infarction (MI) ventricular septal defects (VSDs) is high, and the benefit of surgery is unclear. We aimed to investigate the management and outcomes of post-MI VSD over a 10-year period in a large cohort.

Methods: Data of patients with post-MI VSD admitted in three French university hospitals from 2008 to 2019 were examined.

Outcomes of emergency transcatheter aortic valve replacement in patients with cardiogenic shock: A multicenter retrospective study.

Rescue transcatheter aortic valve replacement (TAVR) in patients with cardiogenic shock is challenging, and there is limited literature on these critical patients. The aim of this study was to determine the characteristics and outcomes of patients undergoing TAVR, feasibility and safety of the procedure, and 1-year mortality factors. Thirty-eight patients with severe aortic disease and cardiogenic shock admitted to two French hospitals from 2015 to 2019 were included.

Mitral valve-in-valve and valve-in-ring procedures: Midterm outcomes in a French nationwide registry.

Objectives: Report contemporary outcomes in patients included in the Mitragister registry and treated with transcatheter mitral valve implantation for failed surgical annuloplasty rings or deteriorated bioprosthesis.

Background: Midterm survival rates have been reported, but little is known about contemporary morbimortality endpoints.

Methods: The primary safety outcome was the technical success rate.

French Hip & Knee Society classification of short-stem hip prostheses: Inter- and intra-observer reproducibility.

Introduction: In total hip replacement (THR), a short stem theoretically provides more physiological force transfer to the proximal femur, conserves bone stock and facilitates minimally invasive surgery. On the other hand, such implants involve a learning curve and incur risk of malpositioning or fracture and of secondary mobilization. There are several types of short stem, and classification is needed.

Sapien 3 Embolization From Ventricle to Aorta in the Setting of Noncalcified Aortic Regurgitation.

Transcatheter aortic valve replacement is currently used off-label for noncalcified aortic valve regurgitation and therefore is restricted to selected cases. In this setting we describe a rare complication of Sapien 3 (Edwards Lifesciences, Irvine, California) embolization from the left ventricle to the descending aorta. Given their technical challenges, such procedures require specific considerations and management.

Radiopacity of Coronary Stents, an In Vitro Comparative Study.

Purpose: Interventional cardiology devices and especially stents are constantly evolving. A good radiopacity is essential to properly position the stent and to reduce the risk of complications during percutaneous coronary intervention (PCI). We wanted to assess the radiopacity of coronary stents.

Standardized fractal bench test evaluation of coronary stents: Performances in bifurcation lesions treated by the re-proximal optimization technique.

Background: Bifurcation lesions in coronary arteries are complex to treat with coronary stents, which are not designed for that purpose and can be unproperly deployed. Moreover, devices are constantly evolving, and so are angioplasty techniques.

Objectives: The aim of this study was to determine the performances of different stents in the treatment of bifurcation lesions using the re-proximal optimization technique (rePOT).

Adult-onset Still's disease revealed by a complete atrioventricular block, totally regressive under corticosteroid therapy.

We report the case of a 40-year-old veterinary surgeon who was admitted for spiking fevers, arthralgia, and a complete atrioventricular block. Tests revealed an inflammatory syndrome, hepatic cytolysis, neutrophilic leukocytosis, and increased troponin levels. Cardiac magnetic resonance imaging showed a small myocarditis but no tissue abnormality on the conduction pathways.

Reduced Chlorine in Drinking Water Distribution Systems Impacts Bacterial Biodiversity in Biofilms.

In drinking water distribution systems (DWDS), a disinfectant residual is usually applied to limit bacterial regrowth. However, delivering water with no or reduced chlorine residual could potentially decrease the selection for antimicrobial resistant microorganisms, favor bacterial regrowth and result in changes in bacterial populations. To evaluate the feasibility of water reduction in local DWDS while ensuring water safety, water quality was measured over 2 months in two different networks, each of them harboring sub-areas with normal and reduced chlorine.

Exchangeable Femoral Neck (Dual-Modular) THA Prostheses Have Poorer Survivorship Than Other Designs: A Nationwide Cohort of 324,108 Patients.

Background: Exchangeable neck stems, defined as those with a dual taper (that is, a modular junction between the femoral head and the femoral neck and an additional junction between the neck and the stem body), were introduced in THA to improve restoration of joint biomechanics (restoring anteversion, offset, and limb length) and reduce the risk of dislocation. However exchangeable necks have been reported to result in adverse effects such as stem fractures and acute local tissue reaction. Whether they result in a net improvement to or impairment of reconstructive survivorship remains controversial.

A numerical model to reproduce squeaking of ceramic-on-ceramic total hip arthroplasty. Influence of design and material.

Background: Modern ceramic (CoC) bearings for hip arthroplasty (THA) have been used in younger patients who expect improved survivorship. However, audible squeaking produced by the implant is an annoying complication. Previous numerical simulations were not able to accurately reproduce in vitro and in vivo observations.

Association Between Total Hip Replacement Characteristics and 3-Year Prosthetic Survivorship: A Population-Based Study.

Importance: Total hip replacement (THR) is successful in treating hip arthritis. Prosthetic survivorship may depend on characteristics of the implant, notably THR fixation technique and bearing surface type.

Objective: To compare THR short-term survivorship according to cement type and bearing surface.

Are gender-specific femoral implants for total knee arthroplasty necessary?

The purpose of this study was to determine the effect of gender on epiphyseal morphology and using this information to determine if an implant product line with a single width provides sufficient bone coverage for the entire population of knees being replaced. Morphology of the distal femoral epiphysis from 420 continuous knees was acquired with a surgical navigation system during primary TKA. A three-dimensional model of the distal femur was generated and used to determine the anterioposterior (AP) and mediolateral (ML) dimensions on 19 different virtual knee sections.

Rotational alignment of the femoral component using trochlear navigation during total knee arthroplasty: a dual-center study of 145 cases.

Rotational alignment of the femoral component during TKA is critical. Here we propose a technique using navigation of the femoral trochlea to determine the rotation of the femoral component. The rotation is considered "ideal" when the component position leads to the arthroplasty trochlea being perfectly superimposed over the native trochlea.

Can hip anatomy be reconstructed with femoral components having only one neck morphology? A study on 466 hips.

This extensive radiographic study asks if there is a statistical relationship between the size of the stem that will best fit the femur and the vertical and lateral offsets of the reconstructed acetabular center, what is the distribution of vertical and lateral offsets in this large and if there is a statistical difference among surgeons in the planned location of the reconstructed acetabular center. On 466 radiographs, five surgeons separately templated stem size and acetabular cup location. The vertical and horizontal coordinates of the reconstructed acetabulum center were measured relative to the planned position of the stem.
