Background: Tricuspid edge to edge repair (TEER) is a novel treatment for severe tricuspid regurgitation and is highly dependent on intraprocedural image quality. To date, transesophageal echocardiography (TEE) has been the primary imaging modality used to guide TEER. The role of intracardiac echocardiography (ICE) has not been assessed. The objective of this study was to describe the use and role of 2-dimensional ICE in the early experience of TEER. Methods: Consecutive patients undergoing TEER (with or without concomitant mitral repair) with off-label use of MitraClip (Abbott, Santa Clara, CA) were included in the study. Utilization of 2-dimensional ICE in comparison with TEE imaging were collected in each procedure through retrospective review of the procedural reports and images. Results: Of 42 TEER cases, ICE was used in 15 (36%) and concomitant mitral repair was performed in 37 (86%). ICE was increasingly used over time for TEER. ICE was able to visualize the tricuspid leaflets with high resolution and provided superior leaflet visualization to TEE in 40% of cases where it was used. Patients treated with ICE guidance tended to have a greater baseline severity of tricuspid regurgitation compared with patients treated with TEE guidance alone (8/15 [53%] massive or greater tricuspid regurgitation versus 6/27 [22%]; P =0.09). Degree of tricuspid regurgitation reduction was similar with TEE alone versus ICE plus TEE guidance (1.9±1.0 versus 2.1±1.1 grade reduction, P =0.28). Conclusions: ICE was increasingly used in the early experience of TEER over time. ICE facilitates leaflet visualization for grasping and is a useful adjunct to TEE during TEER.

Abstract Background This study aimed to describe the mid-term outcomes of different treatments in patients with atrial fibrillation caused tricuspid regurgitation. Methods A retrospective study of patients diagnosed as atrial fibrillation caused moderate-severe tricuspid regurgitation undergoing ablation (n = 411) were reviewed. The surgical cohort (n = 114) underwent surgical ablation and tricuspid valve repair; the catheter cohort (n = 279) was selected from those patients who had catheter ablation. Results The estimated actuarial 5-year survival rates were 96.8% (95% CI: 92.95–97.78) and 92.0% (95% CI: 85.26–95.78) in the catheter and surgical cohort, respectively. Tethering height was showed as independent risk factors for recurrent atrial fibrillation and tricuspid regurgitation in both cohorts. A matched group analysis using propensity-matched was conducted after categorizing total patients by tethering height < 6 mm and ≥ 6 mm. Kaplan–Meier analysis showed in patients with tethering height < 6 mm, there were no differences in survival from mortality, stroke, recurrent atrial fibrillation and tricuspid regurgitation between two groups. In patients with tethering height ≥ 6 mm, there were significantly higher cumulative incidence of stroke (95% CI, 0.047–0.849; P = 0.029), recurrent atrial fibrillation (95% CI, 0.357–09738; P = 0.039) and tricuspid regurgitation (95% CI, 0.359–0.981; P = 0.042) in catheter group. Conclusions Atrial fibrillation caused tricuspid regurgitation resulted in less leaflets coaptation, which risk the recurrence of atrial fibrillation and tricuspid regurgitation. Patients whose tethering height was less than 6 mm showed satisfying improvement in tricuspid regurgitation with the restoration of sinus rhythm after catheter ablation. However, in patients with severe leaflets tethering, the results favored surgical over catheter.

Abstract Background Transcatheter edge-to-edge tricuspid valve repair (TTVR) is a novel treatment option in patients with severe tricuspid regurgitation (TR), right-sided heart failure and prohibitive surgical risk. Purpose We investigated whether RVRR can occur early after TTVR in patients with isolated TR and its potential association with clinical outcome. Method We measured right ventricular parameters by transthoracic echocardiography (TTE) at baseline (BL) in 44 consecutive patients undergoing TTVR for isolated severe TR. We obtained follow-up (FU) TTEs after 1 month. Results At BL, we observed dilated RVs with an RV end-diastolic area (RVEDA) of 28.0±8.3cm2, RV mid diameter of 40.7±7.3mm and tricuspid annulus of 47.5±8.1mm. The majority of patients (63%) showed RV systolic dysfunction with either a tricuspid annular plane excursion (TAPSE) <17mm or fractional area change (FAC) <35%. In 40 Patients (90%), a periprocedural TR reduction by at least 1 degree was achieved (p<0.01). During further clinical FU (272±183 days), 21 patients died (of whom 14 had prior hospitalizations for heart failure before death), 8 patients had hospitalizations for heart failure, 1 patient underwent heart transplantation and 1 patient was lost to clinical FU. We acquired a short-term echocardiographic follow-up (Echo-FU) after 30 days in 36 patients (82%). TR reduction was stable after 1 month with a TR grade ≤2+ in 26 of 36 patients (72%, p<0.01 vs BL). We detected RVRR in the majority of patients with 1-month Echo-FU: RVEDA decreased from 28.8±8.2 to 26.3±7.4cm2 (p<0.01), RV mid diameter from 41.2±7.3 to 38.5±7.7mm (p<0.01) and tricuspid annulus from 48.3±8.3 to 42.8±6.6mm (Figure, p<0.01). We observed a non-significant trend towards reduction of TAPSE (17.5mm to 16.1 mm, p=0.12) and FAC (37.8% to 35.5%, p=0.17), which could represent a normalization of systolic function of a previously hyperactive RV. Next, we evaluated whether RVRR is potentially associated with clinical outcome. We stratified patients into two groups with more or less than median change in RVEDA, RV mid diameter and TV annulus. Fewer combined clinical events (time to death or repeat intervention or first hospitalization for heart failure) were observed in patients with pronounced decrease of RV mid diameter (p=0.03) and TV annulus (Figure, p=0.02) at FU. A decrease of RVEDA showed a non-significant trend towards better outcome (p=0.06). Figure 1 Conclusions Our report demonstrates that RVRR occurs already 1 month after TTVR for isolated TR and is associated with less clinical endpoints.

AbstractA model of asymmetric contributions to the control of different subcomponents of approach- and withdrawal-related emotion and psychopathology is presented. Two major forms of positive affect are distinguished. An approach-related form arises prior to goal attainment, and another form follows goal attainment. The former is hypothesized to be associated with activation of the left prefrontal cortex. Individual differences in patterns of prefrontal activation are stable over time. Hypoactivation in this region is proposed to result in approach-related deficits and increase an individual's vulnerability to depression. Data in support of these proposals are presented. The issue of plasticity is then considered from several perspectives. Contextual factors are superimposed upon tonic individual differences and modulate the magnitude of asymmetry. Pharmacological challenges also alter patterns of frontal asymmetry. A diverse array of evidence was then reviewed that lends support to the notion that these patterns of asymmetry may be importantly influenced by early environmental factors that result in enduring changes in brain function and structure.
