AORTLANTIC: French registry of aortic valve-sparing root replacement, preliminary multicentre results from western France
2022
OBJECTIVES Aortic root aneurysms often affect younger patients in whom valve-sparing surgery is challenging. Among current techniques, aortic valve-sparing root replacement described by Tirone David has shown encouraging results. The AORTLANTIC registry was instituted for a multicentre long-term evaluation of this procedure. The current initial study evaluates the hospital outcomes of the procedure. METHODS This is a retrospective study of patients operated between 1 January 2004 and 31 December 2020 in 6 hospitals in western France. All study data were recorded in the national digital database of the French Society of Cardiac Surgery: EPICARD. RESULTS A total of 524 consecutive patients with a mean age of 53 (15.1) years underwent surgery. 13% (n = 68) of patients presented with acute aortic dissection, 16.5% (n = 86) had associated connective tissue pathology and 7.3% (n = 37) had bicuspid aortic valves. Preoperative aortic regurgitation (AR) ≥2/4 was present in 65.3% (n = 341) of patients. Aortic valvuloplasty was required in 18.6% (n = 95) of patients. At discharge, 92.8% (n = 461) of patients had no or 1/4 AR. The stroke rate was 1.9% (n = 10). Intra-hospital mortality was 1.9% (n = 10). CONCLUSIONS The AORTLANTIC registry includes 6 centres in western France with >500 patients. Despite numerous complex cases (acute aortic dissections, bicuspid aortic valves, preoperative AR), aortic valve-sparing root replacement has a low intra-hospital mortality. The initial encouraging results of this multicentre study warrant further long-term evaluation by future studies.

ObjectivesThe TRI-SCORE reliably predicts in-hospital mortality after isolated tricuspid valve surgery (ITVS) on native valve but has not been tested in the setting of redo interventions. We aimed to evaluate the predictive value of the TRI-SCORE for in-hospital mortality in patients with redo ITVS and to compare its accuracy with conventional surgical risk scores.MethodsUsing a mandatory administrative database, we identified all consecutive adult patients who underwent a redo ITVS at 12 French tertiary centres between 2007 and 2017. Baseline characteristics and outcomes were collected from chart review and surgical scores were calculated.ResultsWe identified 70 patients who underwent a redo ITVS (54±15 years, 63% female). Prior intervention was a tricuspid valve repair in 51% and a replacement in 49%, and was combined with another surgery in 41%. A tricuspid valve replacement was performed in all patients for the redo surgery. Overall, in-hospital mortality and major postoperative complication rates were 10% and 34%, respectively. The TRI-SCORE was the only surgical risk score associated with in-hospital mortality (p=0.005). The area under the receiver operating characteristic curve for the TRI-SCORE was 0.83, much higher than for the logistic EuroSCORE (0.58) or EuroSCORE II (0.61). The TRI-SCORE was also associated with major postoperative complication rates and survival free of readmissions for heart failure.ConclusionRedo ITVS was rarely performed and was associated with an overall high in-hospital mortality and morbidity, but hiding important individual disparities. The TRI-SCORE accurately predicted in-hospital mortality after redo ITVS and may guide clinical decision-making process (www.tri-score.com).

Comparison of the Transarterial and Transthoracic Approaches in Nontransfemoral Transcatheter Aortic Valve Implantation
2019
Transfemoral approach stands as the reference access-route for transcatheter aortic valve implantation (TAVI). Nonetheless, alternatives approaches are still needed in a significant proportion of patients. This study aimed at comparing outcomes between transthoracic-approach (transapical or transaortic) and transarterial-approach (transcarotid or subclavian) TAVI. Data from 191 consecutive patients who underwent surgical-approach TAVI from May 2009 to September 2017 were analyzed. Patients were allocated in 2 groups according to the approach. The primary end point was the 30-day composite of death of any cause, need for open surgery, tamponade, stroke, major or life-threatening bleeding, stage 2 or 3 acute kidney injury, coronary obstruction, or major vascular complications. During the study period, 104 patients underwent transthoracic TAVI (transapical: 60.6%, transaortic: 39.4%) whereas 87 patients underwent transarterial TAVI (subclavian: 83.9%, transcarotid: 16.1%). Logistic EuroSCORE I tended to be higher in transthoracic-TAVI recipients. In-hospital and 30-day composite end point rates were 25.0% and 11.5% (p = 0.025), and 26.0% and 14.9% (p = 0.075) for the transthoracic and transarterial cohorts, respectively. Propensity score-adjusted logistic regression demonstrated no significant detrimental association between the 30-day composite end point and transthoracic access (odds ratio 2.12 95% confidence interval 0.70 to 6.42; p = 0.18). Transarterial TAVI was associated with a shorter length of stay (median: 6 vs 7 days, p <0.001). TAVI approach was not an independent predictor of midterm mortality. In conclusion, nontransfemoral transarterial-approach TAVI is safe, feasible, and associated with comparable rates of major perioperative complications, and midterm mortality compared with transthoracic-approach TAVI.

Electrophysiological Study-Guided Permanent Pacemaker Implantation in Patients With Conduction Disturbances Following Transcatheter Aortic Valve Implantation
2021
Conduction disturbances remain common following transcatheter aortic valve implantation (TAVI). Aside from high-degree atrioventricular block (HAVB), their optimal management remains elusive. Invasive electrophysiological studies (EPS) may help stratify patients at low or high risk of HAVB allowing for an early discharge or permanent pacemaker (PPM) implantation among patients with conduction disturbances. We evaluated the safety and diagnostic performances of an EPS-guided PPM implantation strategy among TAVI recipients with conduction disturbances not representing absolute indications for PPM. All patients who underwent TAVI at a single expert center from June 2017 to July 2020 who underwent an EPS during the index hospitalization were included in the present study. False negative outcomes were defined as patients discharged without PPM implantation who required PPM for HAVB within 6 months of the initial EPS. False positive outcomes were defined as patients discharged with a PPM with a ventricular pacing percentage <1% at follow-up. A total of 78 patients were included (median age 83.5, 39% female), among whom 35 patients (45%) received a PPM following EPS. The sensitivity, specificity, positive and negative predictive values of the EPS-guided PPM implantation strategy were 100%, 89.6%, 81.5%, and 100%, respectively. Six patients suffered a mechanical HAVB during EPS and received a PPM. These 6 patients showed PPM dependency at follow-up. In conclusion, an EPS-guided PPM implantation strategy for managing post-TAVI conduction disturbances appears effective to identify patients who can be safely discharged without PPM implantation.

Contemporary guidelines by the European Society for Cardiology and American College of Cardiology/American Heart Association for the treatment of non-acute myocardial ischaemic syndromes dispute the value of revascularisation and differ in their recommendation to perform revascularisation. A Bayesian network meta-analysis was performed, evaluating the strength of evidence for the comparative incremental effectiveness of coronary artery bypass grafting (CABG) versus percutaneous coronary intervention (PCI) over medical therapy on long-term outcomes.
A hierarchical Bayesian network meta-analysis was designed (PROSPERO CRD42024541215, date 20 May 2024), including randomised controlled trials (RCTs) published between 2005 and 10 June 2025, which consisted of three initial treatment modalities: optimal medical therapy (OMT), PCI+OMT and CABG+OMT. The primary outcome was all-cause mortality at maximum follow-up; secondary outcomes were trates of the rates of myocardial infarction, stroke and re-revascularisation at maximum follow-up, expressed in HRs and 95% credible intervals (CrIs), accompanied by surface under the cumulative ranking curve (SUCRA) scores.
10 RCTs, comprising 10 742 patients, were included. For all-cause mortality, the estimated median HR of CABG+OMT versus OMT was 0.84 (95% CrI 0.68-1.07); the HR of PCI+OMT versus OMT was 0.93 (0.79-1.16); and the HR of CABG+OMT versus PCI+OMT was 0.91 (0.71-1.13). The SUCRAs of a CABG+OMT strategy ranking as the optimal revascularisation treatment regarding mortality, myocardial infarction, stroke and re-revascularisation were 88.1%, 99.7%, 17.5% and 99.5%, respectively. Results were consistent across sensitivity analyses, including in the node-splitting models.
This Bayesian network meta-analysis found that an initial CABG (+OMT) revascularisation strategy was associated with higher probabilities of optimal outcomes, with the exception of stroke, compared with an initial PCI (+OMT) revascularisation strategy, although CrIs overlapped, suggesting that some uncertainty remains.

The current organ shortage in hepatic transplantation leads to increased use of marginal livers. New organ sources are needed, and deceased after circulatory death (DCD) donors present an interesting possibility. However, many unknown remains on these donors and their pathophysiology regarding ischemia reperfusion injury (IRI). Our hypothesis was that DCD combined with abdominal normothermic regional recirculation (ANOR) is not inferior to deceased after brain death (DBD) donors. We performed a mechanistic comparison between livers from DBD and DCD donors in a highly reproducible pig model, closely mimicking donor conditions encountered in the clinic. DCD donors were conditioned by ANOR. We determined that from the start of storage, pro-lesion pathways such as oxidative stress and cell death were induced in both donor types, but to a higher extent in DBD organs. Furthermore, pro-survival pathways, such as resistance to hypoxia and regeneration showed activation levels closer to healthy livers in DCD-ANOR rather than in DBD organs. These data highlight critical differences between DBD and DCD-ANOR livers, with an apparent superiority of DCD in terms of quality. This confirms our hypothesis and further confirms previously demonstrated benefits of ANOR. This encourages the expended use of DCD organs, particularly with ANOR preconditioning.

Recent European Society of Cardiology/European Association for Cardio-Thoracic Surgery (ESC/EACTS) guidelines highlighted some concerns about the randomized clinical trials (RCTs) comparing transcatheter aortic valve implantation (TAVI) and surgical aortic valve replacement (SAVR) for aortic stenosis. Quantification of these biases has not been previously performed.
To assess whether randomization protects RCTs comparing TAVI and SAVR from biases other than nonrandom allocation.
A systematic review of the literature between January 1, 2007, and June 6, 2022, on MEDLINE, Embase, and Cochrane Central Register of Controlled Trials was performed. Specialist websites were also checked for unpublished data.
The study included RCTs with random allocation to TAVI or SAVR with a maximum 5-year follow-up.
Data extraction was performed by 2 independent investigators following the PRISMA guidelines. A random-effects meta-analysis was used for quantifying pooled rates and differential rates between treatments of deviation from random assigned treatment (DAT), loss to follow-up, and receipt of additional treatments.
The primary outcomes were the proportion of DAT, loss to follow-up, and patients who were provided additional treatments and myocardial revascularization, together with their ratio between treatments. The measures were the pooled overall proportion of the primary outcomes and the risk ratio (RR) in the TAVI vs SAVR groups.
The search identified 8 eligible trials including 8849 participants randomly assigned to undergo TAVI (n = 4458) or SAVR (n = 4391). The pooled proportion of DAT among the sample was 4.2% (95% CI, 3.0%-5.6%), favoring TAVI (pooled RR vs SAVR, 0.16; 95% CI, 0.08-0.36; P < .001). The pooled proportion of loss to follow-up was 4.8% (95% CI, 2.7%-7.3%). Meta-regression showed a significant association between the proportion of participants lost to follow-up and follow-up time (slope, 0.042; 95% CI, 0.017-0.066; P < .001). There was an imbalance of loss to follow-up favoring TAVI (RR, 0.39; 95% CI, 0.28-0.55; P < .001). The pooled proportion of patients who had additional procedures was 10.4% (95% CI, 4.4%-18.5%): 4.6% (95% CI, 1.5%-9.3%) in the TAVI group and 16.5% (95% CI, 7.5%-28.1%) in the SAVR group (RR, 0.27; 95% CI, 0.15-0.50; P < .001). The imbalance between groups also favored TAVI for additional myocardial revascularization (RR, 0.40; 95% CI, 0.24-0.68; P < .001).
This study suggests that, in RCTs comparing TAVI vs SAVR, there are substantial proportions of DAT, loss to follow-up, and additional procedures together with systematic selective imbalance in the same direction characterized by significantly lower proportions of patients undergoing TAVI that might affect internal validity.

Once common in Eastern Atlantic and Mediterranean coastal waters, the angelshark (Squatina squatina) has disappeared from 90% of its historical geographic range over the last century. Populations have drastically declined, likely due to the combined effects of overfishing, coastal habitat destruction, and the species' slow life history traits. The island of Corsica remains one of the last Mediterranean refuges for this IUCN Critically Endangered species, underscoring the need for conservation action. Given the difficulty of observing this benthic shark, we employed genomic methods to investigate the fine‐scale spatial genetic structure, genetic diversity, and effective population size. Skin samples were opportunistically collected from accidental bycatch of angelsharks by local fishers in eastern Corsica and genotyped for 9699 Single Nucleotide Polymorphisms. We show that these individuals belong to a single population and exhibit high site fidelity, particularly among females, supporting male‐biased dispersal. Genetic relatedness analyses identified 35 close family relationships, with 42% of sampled individuals showing a close relative. Additionally, we revealed multiple paternity within a single litter, suggesting a polyandrous mating system not previously documented in Squatinidae. The estimated effective population size of 290 individuals (95% CI: 209–453) is concerning given the persistent bycatch of hundreds of angelsharks by local artisanal fisheries during the annual spring reproductive aggregation of Spicara smaris. Protecting these ephemeral breeding colonies would not only benefit angelsharks but also help sustain numerous other threatened elasmobranchs and commercially important fish species (i.e., Zeus faber). Our findings highlight the value of integrating genomic tools into the conservation of elusive marine species. Conservation efforts should focus on reducing bycatch through gear modifications, seasonal fishing restrictions, and preserving estuaries. Studying and protecting this Corsican refuge is of paramount importance, as it could serve as a source population for restoring angelshark populations in formerly abundant areas. This first genomic insight into a key Mediterranean angelshark stronghold reveals an effective population size below critical conservation thresholds, high site fidelity, and multiple paternity. Despite evidence of active reproduction, ongoing bycatch remains a major threat, underscoring the urgent need for conservation actions.

Aim The Mediterranean Sea is one of the most anthropized seas in the world but also a marine biodiversity hotspot with many fish species under threat. The main goal of the study is to test whether on the heavily fished and anthropized Mediterranean coast, the less impacted Corsica and Balearic Islands, can be considered as refugia for threatened and elasmobranch fishes independently of protection by marine reserves. Location The French Mediterranean coast and three north‐western Mediterranean islands: Corsica and also Mallorca and Minorca from the Balearic archipelago. Methods We performed 187 fish surveys using environmental DNA metabarcoding on three islands and 109 along the continental coast. Of the 78 surveys on islands 22 correspond to no‐take marine reserves and of the 109 continental surveys 26 were carried out within reserves. After eDNA filtration, extraction, amplification, and sequencing we estimated the number of fish species but also the number commercial, threatened and elasmobranch fish species on each sample. We then performed an ANOVA by permutation to test the effect of insularity and protection on these four biodiversity metrics. We also modelled these four biodiversity metrics as a function of protection and human pressure but also environmental, habitat and sampling conditions. We also built species accumulation curves to obtain asymptotes representing the potential regional pools for each species category on both island and continental coasts. Results We obtained a total of 175,982,610 reads over the 187 eDNA samples that were assigned to 153 fish species including 17 elasmobranch species among which 7 were only detected on islands. We observed a higher total fish richness on continental than island surveys regardless of protection but a higher threatened and elasmobranch fish richness on the island than on continental surveys. We obtained a significant, negative and predominant human gravity impact on the diversity of elasmobranch species. The modelled asymptote reached 148 teleostean fish species on islands and 196 on the continental coastline with a very similar rate of diversity increase with sampling effort but the shape of the species accumulation curves differed markedly for elasmobranchs with a stronger increase in diversity with sampling effort on islands. Main Conclusions Our findings highlight that Mediterranean islands can be refugia for sharks and rays but also threatened fishes in this overexploited region. Our results also suggest that reducing or banning trawling activities may play a key role for conserving vulnerable fishes, beyond the benefits of no‐take marine reserves, which appear limited on these large home‐range species.
