Efficacy of simulation-based training on transoesophageal echocardiography learning in a multicentre randomised controlled trial: SIMULATOR study

Background Evidence on the impact of simulation-based training in transesophageal echocardiography (TEE) is scarce. Purpose We aimed to assess the efficacy of simulation-based versus traditional teaching on TEE knowledge and skills for cardiology residents. Methods Between November 2020 and November 2021, all consecutive cardiology residents inexperienced from TEE were randomised (1:1, n=324) through 42 French University Centers into two groups with or without simulation support (either a simulation group or a traditional group). The coprimary outcomes were the scores in the final theoretical and practical tests 3 months after the training. TEE duration and the feelings of residents were also assessed. An economic analysis was also performed. Results While the theoretical and practical test scores were similar between the two groups before the training (respectively P=0.80 and P=0.51), the residents in the simulation group displayed higher theoretical test and practical test scores after the training than those in the traditional group (respectively 47.2±15.6% vs. 38.3±19.8%, P<0.0001 and 74.5±17.7% vs. 59.0±25.1%, P<0.0001). Subgroups analyses showed that the efficacy of the simulation training was even greater when performed at the beginning of residency (P<0.0001). After the training, the duration to perform a complete TEE was significantly lower in the simulation group than in the traditional group (respectively 8.3±1.4 min vs. 9.4±1.2 min, P<0.0001). Finally, residents' feelings were better in the simulation group than in the traditional group across all components (P<0.0001). Compared to the traditional group, the average additional cost per resident of the simulation program was respectively €1,785, €942 or €662 for 20, 40 and 60 residents. Conclusion Simulation-based teaching on TEE showed a significant improvement in knowledge, skills, and feelings of cardiology residents as well as a reduction in the duration to complete the examination.

Redo isolated tricuspid valve surgery: prediction of in-hospital mortality using the TRI-SCORE

Background Redo isolated tricuspid valve surgery (ITVS) is rarely performed. The TRI-SCORE reliably predicts in-hospital mortality after ITVS on native valve but has not been tested in the setting of redo interventions. Purpose We aimed to compare the predictive value of the TRI-SCORE to other surgical risk scores for redo ITVS. Methods Using a mandatory administrative database, we identified all consecutive adult patients who underwent a redo ITVS at 12 French tertiary centers between 2007 and 2017. Baseline characteristics and outcomes were collected from chart review and the TRI-SCORE, Logistic EuroSCORE, EuroSCORE II and STS were calculated. Results We identified 70 patients who underwent a redo ITVS (mean age 54±15 years, 63% female). Prior intervention was a repair in 51% and a replacement in 49%. A tricuspid valve replacement was performed in all patients. In-hospital mortality was 10%. The TRI-SCORE was the only risk score associated with in-hospital mortality (p=0.01). Area under the receiver operating characteristic curve for the TRI-SCORE was 0.83, much higher than with logistic EuroSCORE (0.58), EuroSCORE II (0.61) or STS (0.59). The table presents the observed and predicted values of in-hospital mortality according to TRI-SCORE categories. Conclusion The TRI-SCORE accurately predicted in-hospital mortality after redo isolated tricuspid valve surgery and may guide the clinical decision-making process especially as transcatheter therapies are emerging.

FRIPON, the French fireball network

International audienceFRIPON (Fireball Recovery and InterPlanetary Observation Network) [4](Colas et al, 2014) was recently founded by ANR (Agence Nationale de la Recherche). Its aim is to connect meteoritical science with asteroidal and cometary science in order to better understand solar system formation and evolution. The main idea is to set up an observation network covering all the French territory to collect a large number of meteorites (one or two per year) with accurate orbits, allowing us to pinpoint possible parent bodies. 100 all-sky cameras will be installed at the end of 2015 forming a dense network with an average distance of 100km between stations. To maximize the accuracy of orbit determination, we will mix our optical data with radar data from the GRAVES beacon received by 25 stations [5](Rault et al, 2015). As both the setting up of the network and the creation of search teams for meteorites will need manpower beyond our small team of professionals, we are developing a citizen science network called Vigie-Ciel [6](Zanda et al, 2015). The public at large will thus be able to simply use our data, participate in search campaigns or even setup their own cameras
