RESUMO
BACKGROUND: Even after atrial fibrillation (AF) catheter ablation, many patients still experience relevant symptom burden. The objective of the MENTAL AF trial was to determine whether app-based mental training (MT) during the 3 months following pulmonary vein isolation reduces AF-related symptoms. METHODS AND RESULTS: Patients scheduled for pulmonary vein isolation were enrolled and randomized 1:1 to either app-based MT or usual care. Of 174 patients, 76 in the MT and 75 in the usual care group were included in the final analysis. The intervention was delivered by a daily 10-minute app-based MT. The primary outcome was the intergroup difference of the mean AF6 sum score, an AF-specific questionnaire, during the 3-month study period. Secondary outcomes included quality-of-life measures such as the AFEQT (Atrial Fibrillation Effect on Quality of Life). Mean age (SD) was 61 (8.7) years and 61 (41%) were women. The mean AF6 sum score over the study period was 8.9 (6.9) points in the MT group and 12.5 (10.1) in the usual care group (P=0.011). This referred to a reduction in the AF6 sum score compared with baseline of 75% in MT and 52% for usual care (P<0.001). The change in the AFEQT Global Score was 22.6 (16.3) and 15.7 (22.1), respectively; P=0.026. CONCLUSIONS: MENTAL AF showed that app-based MT as an adjunctive treatment tool following pulmonary vein isolation was feasible. App-based MT was found to be superior to standard care in reducing AF-related symptom burden and improving health-related quality of life.

AIMS: The aim of this study was to assess the pathophysiological implications of severe tricuspid regurgitation (TR) in patients with heart failure with preserved ejection fraction (HFpEF) by using tricuspid transcatheter edge-to-edge repair (T-TEER) as a model of right ventricular (RV) volume overload relief. METHODS AND RESULTS: This prospective interventional single arm trial (NCT04782908) included patients with invasively diagnosed HFpEF. The following parameters were prospectively assessed before and after T-TEER: left ventricular (LV) diastolic properties by invasive pressure-volume loop recordings; biventricular time-volume curves and function as well as septal curvature by cardiac magnetic resonance imaging; strain analyses for timing of septal motion. Overall, 20 patients (median age 78, interquartile range [IQR] 72-83 years, 65% female) were included. T-TEER reduced TR by a median of 2 (of 5) grades (IQR 2-1). T-TEER increased LV stroke volume and LV end-diastolic volume (LVEDV) (p < 0.001), without increasing LV end-diastolic pressure (LVEDP) (p = 0.094), consequently diastolic function improved with a reduction in LVEDP/LVEDV (p = 0.001) and a rightward shift of the end-diastolic pressure-volume relationship. The increase in LVEDV correlated with a decrease in RV end-diastolic volume (p < 0.001) and LV transmural pressure increased (p = 0.028). Secondary to a decrease in early RV filling, improvements in early LV filling were observed, correlating with an alleviation of leftwards bowing of the septum (p < 0.01, respectively). CONCLUSION: Diastolic LV properties in patients with HFpEF and severe TR are importantly determined by ventricular interaction in the setting of RV volume overload. T-TEER reduces RV volume overload and improves biventricular interaction and physiology.

BACKGROUND: Data on the prognostic role of the TRI-SCORE in patients undergoing transcatheter tricuspid valve intervention (TTVI) are limited. OBJECTIVES: The aim of this study was to evaluate the performance of the TRI-SCORE in predicting outcomes of patients undergoing TTVI. METHODS: TriValve (Transcatheter Tricuspid Valve Therapies) is a large multicenter multinational registry including patients undergoing TTVI. The TRI-SCORE is a risk model recently proposed to predict in-hospital mortality after tricuspid valve surgery. The TriValve population was stratified based on the TRI-SCORE tertiles. The outcomes of interest were all-cause death and all-cause death or heart failure hospitalization. Procedural complications and changes in NYHA functional class were also reported. RESULTS: Among the 634 patients included, 223 patients (35.2%) had a TRI-SCORE between 0 and 5, 221 (34.8%) had 6 or 7, and 190 (30%) had ≥8 points. Postprocedural blood transfusion, acute kidney injury, new atrial fibrillation, and in-hospital mortality were more frequent in the highest TRI-SCORE tertile. Postprocedure length of stay increased with a TRI-SCORE increase. A TRI-SCORE ≥8 was associated with an increased risk of 30-day all-cause mortality and all-cause mortality and the composite endpoint assessed at a median follow-up of 186 days (OR: 3.00; 95% CI: 1.38-6.55; HR: 2.17; 95% CI: 1.78-4.13; HR: 2.08, 95% CI: 1.57-2.74, respectively) even after adjustment for procedural success and EuroSCORE II or Society of Thoracic Surgeons Predicted Risk of Mortality. The NYHA functional class improved across all TRI-SCORE values. CONCLUSIONS: In the TriValve registry, the TRI-SCORE has a suboptimal performance in predicting clinical outcomes. However, a TRISCORE ≥8 is associated with an increased risk of clinical events and a lack of prognostic benefit after successful TTVI.
