RESUMEN
OBJECTIVES: Patients undergoing surgical tricuspid valve replacement (TVR) are at high risk of atrioventricular conduction disorders. Because implanting a lead through the tricuspid bioprosthesis is discouraged, the patients who undergo TVR in our centre are usually given a prophylactic epicardial pacemaker. Our aim was to assess the benefits and risks of this strategy. METHODS: Among the patients who underwent TVR with prophylactic epicardial pacemaker implantation, clinical evaluations and pacemaker reports were analysed retrospectively after surgery. The need for cardiac pacing were assessed by characterizing the atrioventricular conduction, while the risks were evaluated by listing and adjudicating post-operative events. RESULTS: A total of 80 patients were analysed (mean age was 57 ± 16 years old, 30% males). TVR was isolated in 28 (35%) patients, but most often associated with another valve surgery. In the postoperative period, heart rhythm was analysed in 59/80 patients during a median follow-up of 35 months. Cardiac pacing was needed in 46% patients: 14% had complete pacing dependency, 17% had high degree AV block, while 15% had a high ventricular pacing rate (>80%). No pre- or per-operative variables could predict cardiac pacing requirement. Post-operatively, a spontaneous heart rate >70 bpm (P = 0.02) and the presence of narrow QRS (P = 0.03) were significantly associated with a lower risk of cardiac pacing requirement. Complications related to epicardial pacemaker were documented in 2 (2.5%) patients. CONCLUSIONS: After TVR, cardiac pacing was needed in 46% of patients for post-operative atrioventricular conduction disorders. This high incidence associated with an acceptable safety profile supports a prophylactic epicardial pacing strategy for the patients undergoing TVR.

OBJECTIVE: Despite recent advances in surgical and interventional techniques, knowledge on the management of carcinoid heart disease (CHD) remains limited. In a cohort of patients with liver metastases of midgut neuroendocrine tumours (NETs), we aimed to describe the perioperative management and short-term outcomes of CHD. METHODS: From January 2003 to June 2022, consecutive patients with liver metastases of midgut NETs and severe CHD (severe valve disease with symptoms and/or right ventricular enlargement) were included at Beaujon and Bichat hospitals. All patients underwent clinical evaluation and echocardiography. RESULTS: Out of 43 (16%) consecutive patients with severe CHD and liver metastases of midgut NETs, 79% presented with right-sided heart failure. Tricuspid valve replacement was performed in 26 (53%) patients including 19 (73%) cases of combined pulmonary valve replacement. The 30-day postoperative mortality rate was high (19%), and preoperative heart failure was associated with worse survival (p=0.02). Epicardial pacemakers were systematically implanted in operated patients and 25% were permanently paced. A postoperative positive right ventricular remodelling was observed (p<0.001). A greater myofibroblastic infiltration was observed in pulmonary versus tricuspid valves (p<0.001), suggesting that they may have been explanted at an earlier stage of the disease than the tricuspid valve, with therefore potential for evolution. CONCLUSIONS: We observed a high postoperative mortality rate and baseline right-sided heart failure was associated with worse outcome. In surviving patients, a positive right ventricular remodelling was observed. Prospective, multicentre studies are warranted to better define the management strategy and to identify biomarkers associated with outcome in CHD.

Tricuspid valve (TV) surgery carries a high risk of atrioventricular block. In this report, we illustrate several options for managing conduction disorders after TV surgery. The choice of cardiac implantable devices must take account of several parameters such as surgical procedure, patient's rhythm and history, and etiology of TV disease. (Level of Difficulty: Intermediate.).
RESUMEN
Importance: Evidence is scarce on the effectiveness of simulation-based training in transesophageal echocardiography (TEE). Objective: To assess the effectiveness of simulation-based teaching vs traditional teaching of TEE knowledge and skills of cardiology fellows. Design, Setting, and Participants: Between November 2020 and November 2021, all consecutive cardiology fellows inexperienced in TEE from 42 French university centers were randomized (1:1; n = 324) into 2 groups with or without simulation support. Main Outcomes and Measures: The co-primary outcomes were the scores in the final theoretical and practical tests 3 months after the training. TEE duration and the fellows' self-assessment of their proficiency were also assessed. Results: While the theoretical and practical test scores were similar between the 2 groups (324 participants; 62.6% male; mean age, 26.4 years) before the training (33.0 [SD, 16.3] points vs 32.5 [SD, 18.5] points; P = .80 and 44.2 [SD, 25.5] points vs 46.1 [SD, 26.1] points; P = .51, respectively), the fellows in the simulation group (n = 162; 50%) displayed higher theoretical test and practical test scores after the training than those in the traditional group (n = 162; 50%) (47.2% [SD, 15.6%] vs 38.3% [SD, 19.8%]; P < .001 and 74.5% [SD, 17.7%] vs 59.0% [SD, 25.1%]; P < .001, respectively). Subgroup analyses showed that the effectiveness of the simulation training was even greater when performed at the beginning of the fellowship (ie, 2 years or less of training) (theoretical test: an increase of 11.9 points; 95% CI, 7.2-16.7 vs an increase of 4.25 points; 95% CI, -1.05 to 9.5; P = .03; practical test: an increase of 24.9 points; 95% CI, 18.5-31.0 vs an increase of 10.1 points; 95% CI, 3.9-16.0; P < .001). After the training, the duration to perform a complete TEE was significantly lower in the simulation group than in the traditional group ( 8.3 [SD, 1.4] minutes vs 9.4 [SD, 1.2] minutes; P < .001, respectively). Additionally, fellows in the simulation group felt more ready and more confident about performing a TEE alone after the training (mean score, 3.0; 95% CI, 2.9-3.2 vs mean score, 1.7; 95% CI, 1.4-1.9; P < .001 and mean score, 3.3; 95% CI, 3.1-3.5 vs mean score, 2.4; 95% CI, 2.1-2.6; P < .001, respectively). Conclusions and Relevance: Simulation-based teaching of TEE showed a significant improvement in the knowledge, skills, and self-assessment of proficiency of cardiology fellows, as well as a reduction in the amount of time needed to complete the examination. These results should encourage further investigation of clinical performance and patient benefits of TEE simulation training.

OBJECTIVES: The 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. METHODS: Using 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. RESULTS: We 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. CONCLUSION: Redo 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).

AIMS: Isolated tricuspid valve surgery (ITVS) is considered to be a high-risk procedure, but in-hospital mortality is markedly variable. This study sought to develop a dedicated risk score model to predict the outcome of patients after ITVS for severe tricuspid regurgitation (TR). METHODS AND RESULTS: All consecutive adult patients who underwent ITVS for severe non-congenital TR at 12 French centres between 2007 and 2017 were included. We identified 466 patients (60 ± 16 years, 49% female, functional TR in 49%). In-hospital mortality rate was 10%. We derived and internally validated a scoring system to predict in-hospital mortality using multivariable logistic regression and bootstrapping with 1000 re-samples. The final risk score ranged from 0 to 12 points and included eight parameters: age ≥70 years, New York Heart Association Class III-IV, right-sided heart failure signs, daily dose of furosemide ≥125 mg, glomerular filtration rate <30 mL/min, elevated bilirubin, left ventricular ejection fraction <60%, and moderate/severe right ventricular dysfunction. Tricuspid regurgitation mechanism was not an independent predictor of outcome. Observed and predicted in-hospital mortality rates increased from 0% to 60% and from 1% to 65%, respectively, as the score increased from 0 up to ≥9 points. Apparent and bias-corrected areas under the receiver operating characteristic curves were 0.81 and 0.75, respectively, much higher than the logistic EuroSCORE (0.67) or EuroSCORE II (0.63). CONCLUSION: We propose TRI-SCORE as a dedicated risk score model based on eight easy to ascertain parameters to inform patients and physicians regarding the risk of ITVS and guide the clinical decision-making process of patients with severe TR, especially as transcatheter therapies are emerging (www.tri-score.com).

Introduction: Simulation-based training in transesophageal echocardiography (TEE) seems promising. However, data are limited to non-randomized or single-center studies. To assess the impact of simulation-based vs. traditional teaching on TEE knowledge and performance for medical residents in cardiology. Materials and Methods: Nationwide prospective randomized multicenter study involving 43 centers throughout France allowing for the inclusion of >70% of all French cardiology residents. All cardiology residents naive from TEE will be included. Randomization with stratification by center will allocate residents to either a control group receiving theoretical knowledge by e-learning only, or to an intervention group receiving two simulation-based training sessions on a TEE simulator in addition. Results: All residents will undergo both a theoretical test (0-100 points) and a practical test on a TEE simulator (0-100 points) before and 3 months after the training. Satisfaction will be assessed by a 5-points Likert scale. The primary outcomes will be to compare the scores in the final theoretical and practical tests between the two groups, 3 months after the completion of the training. Conclusion: Data regarding simulation-based learning in TEE are limited to non-randomized or single-center studies. The randomized multicenter SIMULATOR study will assess the impact of simulation-based vs. traditional teaching on TEE knowledge and performance for medical residents in cardiology, and whether such an educational program should be proposed in first line for TEE teaching.
RESUMEN
AIMS: The aim of this study was to identify determinants of in-hospital and mid-term outcomes after isolated tricuspid valve surgery (ITVS) and more specifically the impact of tricuspid regurgitation (TR) mechanism and clinical presentation. METHODS AND RESULTS: Among 5661 consecutive adult patients who underwent a tricuspid valve (TV) surgery at 12 French tertiary centres in 2007-2017 collected from a mandatory administrative database, we identified 466 patients (8% of all tricuspid surgeries) who underwent an ITVS. Most patients presented with advanced disease [47% in New York Heart Association (NYHA) III/IV, 57% with right-sided heart failure (HF) signs]. Tricuspid regurgitation was functional in 49% (22% with prior left-sided heart valve surgery and 27% isolated) and organic in 51% (infective endocarditis in 31% and other causes in 20%). In-hospital mortality and major complications rates were 10% and 31%, respectively. Rates of survival and survival free of HF readmission were 75% and 62% at 5 years. Patients with functional TR incurred a worse in-hospital mortality than those with organic TR (14% vs. 6%, P = 0.004), but presentation was more severe. Independent determinants of outcomes were NYHA Class III/IV [odd ratios (OR) = 2.7 (1.2-6.1), P = 0.01], moderate/severe right ventricular dysfunction [OR = 2.6 (1.2-5.8), P = 0.02], lower prothrombin time [OR = 0.98 (0.96-0.99), P = 0.008], and with borderline statistical significance, right-sided HF signs [OR = 2.4 (0.9-6.5), P = 0.06] while TR mechanism was not [OR = 0.7 (0.3-1.8), P = 0.88]. CONCLUSION: Isolated TV surgery was associated with high mortality and morbidity, both in hospital and during follow-up, predicted by the severity of the presentation but not by TR mechanism. Our results suggest that TV intervention should be performed earlier in the course of the disease.
