Project description:BackgroundTo identify the association between tricuspid annular circumference and secondary tricuspid regurgitation and analyze the risk factors of recurrent tricuspid regurgitation after concomitant tricuspid annuloplasty during left heart surgery.MethodsFrom October 2018 to June 2019, a total of 117 patients receiving concomitant tricuspid annuloplasty within left heart surgery were enrolled. Severity of tricuspid regurgitation was classified as 4 subtypes: normal, mild, moderate and severe. Perioperative data and mid-term outcome were collected. Tricuspid annular circumference (TAC) was measured under cardiac arrest during surgery procedure by cardioplegia. Optimal TAC and TAC index (TAC/body surface area, BSA) cutoffs of significant tricuspid annulus dilatation (moderate and severe) were obtained. Univariable and multivariable logistic regression analyses were performed to identify the risk factors of postoperative recurrent tricuspid regurgitation. The follow up period is 13-19 months (mean 15.5 ± 3.2 months).ResultsThere was 1 patient was excluded who died after surgery. A total of 116 patients receiving tricuspid annuloplasty were included. Optimal cutoffs of significant tricuspid annulus dilatation were recommended (TAC 11.45 cm, Sensitivity 82.89%, Specificity 73.68%, AUC 0.915; TAC index 7.09 cm/m2, Sensitivity 73.68%, Specificity 85%, AUC 0.825, respectively). Based on findings of multivariable logistic regression, it has been showed that TAC index and postoperative atrial fibrillation were the independent risk factors of recurrent regurgitation after surgery. Optimal TAC index cutoff to predict recurrent tricuspid regurgitation was 7.86 cm/m2 CONCLUSIONS: The severity of secondary tricuspid regurgitation is associated with the tricuspid annular circumference. The cut-offs of significant tricuspid regurgitation (more than moderate) were TAC 11.45 cm and TAC index 7.09 cm/m2, respectively. Clinically, concomitant tricuspid annuloplasty is relative safe and effective. TAC index ≥ 7.86 cm/m2 and postoperative atrial fibrillation are the risk factors of recurrent significant tricuspid regurgitation after concomitant tricuspid annuloplasty during left heart surgery.

Project description:ObjectiveWe investigated the effect of morphological diversity of the tricuspid valve with multiple posterior leaflets on the technical outcomes of tricuspid valve repair.MethodsFrom April 2016 to November 2020, 141 patients were diagnosed with secondary tricuspid regurgitation associated with left heart disease and underwent tricuspid valve repair. We retrospectively analyzed the clinical and echocardiographic data of patients who underwent both preoperative and postoperative transthoracic echocardiography. We divided the patients into two groups according to the surgical technique used to treat tricuspid regurgitation: ring annuloplasty alone (Group 1, n = 109) or additional approximation of leaflet edges (edge-to-edge repair) with ring annuloplasty (Group 2, n = 32). We measured the morphological diversity of the tricuspid valve during the operation in all patients.ResultsThe preoperative tricuspid regurgitation score was higher in Group 2 than in Group 1 (2.1 ± 0.78 vs. 1.6 ± 0.7, respectively; p = 0.0046), and Group 2 contained more patients with two posterior leaflets than Group 1 [20 (63%) vs. 36 (33%), respectively; p = 0.003]. The univariate and multivariate logistic regression analyses showed that the presence of two posterior leaflets was an independent risk factor for additional procedures during tricuspid valve repair (odds ratio, 2.6; 95% confidence interval, 1.1-6.1; p = 0.033).ConclusionsAdditional procedures to reduce tricuspid regurgitation were required more frequently in patients with two posterior leaflets of the tricuspid valve. The morphological diversity of two posterior leaflets is a potential risk factor for a more complicated tricuspid repair.

Project description:BackgroundA mismatch between tricuspid leaflet size and annular dilation is one of the morphological features tied to the development of tricuspid regurgitation (TR).AimsWe assessed the association of the leaflet-to-annulus index (LAI) with residual TR after transcatheter edge-to-edge repair (TEER).MethodsConsecutive patients who underwent TEER for TR were enrolled. Significant residual TR was defined as a post-procedural TR ≥3+, and patients were divided into two groups according to the amount of residual TR. The LAI was retrospectively calculated using procedural transoesophageal echocardiography and was defined as follows: (anterior leaflet length+septal leaflet length)/septolateral tricuspid annulus diameter.ResultsOf 140 patients, 43 patients had residual TR ≥3+ after TEER. The patients with residual TR ≥3+ had a lower LAI compared to those with residual TR <3+ (1.04±0.10 vs 1.13±0.09; p=0.001). In multivariable analysis, the LAI was associated with residual TR ≥3+ (odds ratio [OR] [per 0.1 increase]: 0.57; 95% confidence interval [95% CI]: 0.35-0.94; p=0.02), independent of baseline TR severity or coaptation gap size. Patients with residual TR ≥3+ had a higher incidence of the composite outcome, consisting of all-cause mortality and heart failure hospitalisation within one year after TEER (47.1% vs 26.6%, p=0.02). Residual TR ≥3+ was an independent predictor of the composite outcome within one year (hazard ratio: 2.04; 95% CI: 1.01-4.11; p=0.04).ConclusionsThe leaflet-to-annulus mismatch (i.e., LAI) is associated with residual TR ≥3+ after TEER for TR. A detailed echocardiographic analysis of the tricuspid valve will be conducive to identifing suitable subjects for TEER.

Project description:An 86-year-old patient experienced progressive heart failure symptoms. Echocardiographic evaluation revealed severe tricuspid regurgitation, which was treated by transcatheter edge-to-edge repair. During the procedure, single leaflet device attachment occurred. On the basis of a prohibitive surgical risk, caval valve implantation was performed, with no notable complications. (Level of Difficulty: Advanced.).

Project description:AimThe aim of this study was to analyse the predictive value of CTA-determined tricuspid annular dilatation (TAD) on the persistence of tricuspid regurgitation (TR) in patients undergoing transcatheter aortic valve replacement (TAVR) for severe aortic stenosis (AS) and concomitant at least moderate TR.Methods and results288 consecutive patients treated with TAVR due to severe AS and concomitant at least moderate TR at baseline were included in the analysis. As cutoff for TAD, the median value of the CTA-determined, to the body surface area-normalized tricuspid annulus diameter (25.2 mm/m2) was used. TAD had no impact on procedural characteristics or outcomes, including procedural death and technical or device failure according to the Valve Academic Research Consortium 3 criteria. However, the primary outcome of the study-TR persistence after TAVR was significantly more frequent in patients with compared to patients without TAD (odds ratio 2.60, 95% confidence interval 1.33-5.16, p < 0.01). Multivariable logistic regression analysis, adjusting for clinical and echocardiographic baseline characteristics, which are known to influence aetiology or severity of TR, confirmed TAD as an independent predictor of TR persistence after TAVR (adjusted odds ratio 2.30, 95% confidence interval 1.20-4.46, p = 0.01). Moreover, 2 year all-cause mortality was significantly higher in patients with persistence or without change of TR compared to patients with TR improvement (log-rank p < 0.01).ConclusionIn patients undergoing TAVR for severe AS and concomitant at least moderate TR at baseline, TAD is a predictor of TR persistence, which is associated with increased 2-year all-cause mortality.

Project description:AimsTranscatheter tricuspid edge-to-edge repair (T-TEER) has gained widespread use for the treatment of tricuspid regurgitation (TR) in symptomatic patients with high operative risk. Although secondary TR is the most common pathology, some patients exhibit primary or predominantly primary TR. Characterization of patients with these pathologies in the T-TEER context has not been systematically performed.Methods and resultsPatients assigned to T-TEER by the interdisciplinary heart team were consecutively recruited in two European centres over 4 years. Echocardiographic images were evaluated to distinguish between primary and secondary causes of TR. Both groups were compared concerning procedural results. A total of 339 patients were recruited, 13% with primary TR and 87% with secondary TR. Patients with primary TR had a smaller right ventricle (basal diameter 45 vs. 49 mm, P = 0.004), a better right ventricular function (fractional area change 45 vs. 41%, P = 0.001), a smaller right (28 vs. 34 cm2, P = 0.021) and left (52 vs. 67 mL/m2, P = 0.038) atrium, and a better left ventricular ejection fraction (60 vs. 52%, P = 0.005). The severity of TR was similar in primary and secondary TR at baseline (TR vena contracta width pre-interventional 13 ± 4 vs. 14 ± 5 mm, P = 0.19), and T-TEER significantly reduced TR in both groups (TR vena contracta width post-interventional 4 ± 3 vs. 5 ± 5 mm, P = 0.10). These findings remained stable after propensity score matching. Complications were similar between both groups.ConclusionT-TEER confers equally safe and effective reduction of TR in patients with primary and secondary TR.

Project description:Tricuspid regurgitation (TR) is a risk factor for mortality in pulmonary hypertension (PH). TR severity varies among patients with comparable degrees of PH and right ventricular remodeling. The contribution of leaflet adaptation to the pathophysiology of TR has yet to be examined. We hypothesized that tricuspid leaflet area (TLA) is increased in PH, and that the adequacy of this increase relative to right ventricular remodeling determines TR severity.A prospective cohort of 255 patients with PH from pre and postcapillary pathogeneses was assembled from 2 centers. Patients underwent a 3-dimensional echocardiogram focused on the tricuspid apparatus. TLA was measured with the Omni 4D software package. Compared with normal controls, patients with PH had a 2-fold increase in right ventricular volumes, 62% increase in annular area, and 49% increase in TLA. Those with severe TR demonstrated inadequate increase in TLA relative to the closure area, such that the ratio of TLA:closure area <1.78 was highly predictive of severe TR (odds ratio, 68.7; 95% confidence interval, 16.2-292.7). The median vena contracta width was 8.5 mm in the group with small TLA and large closure area as opposed to 4.8 mm in the group with large TLA and large closure area.TLA plays a significant role in determining which patients with PH develop severe functional TR. The ratio of TLA:closure area, reflecting the balance between leaflet adaptation versus annular dilation and tethering forces, is an indicator of TR severity that may identify which patients stand to benefit from leaflet augmentation during tricuspid valve repair.

Project description:BackgroundAccurate sizing of the tricuspid valve annulus is essential for determining the optimal timing of tricuspid valve (TV) intervention. Two-dimensional (2D) echocardiography has limitations for comprehensive TV analysis. Three-dimensional (3D) imaging of the valve provides a better understanding of its spatial anatomy and enables more accurate measurements of TV structures.ObjectivesThe study aimed to analyze tricuspid annulus (TA) parameters in normal heart and in different grades of functional tricuspid regurgitation (TR); to compare TA measurements obtained by 2D and 3D echocardiography.MethodsOne hundred fifty-five patients (median age 65 years, 57% women) with normal TV and different functional TR grades underwent 2D and 3D transthoracic echocardiography. The severity of TR was estimated using multiparametric assessment according to the guidelines. Mid-systolic 3D TA parameters were calculated using TV dedicated software. The conventional 2D systolic TA measurements in a standard four-chamber view were performed.ResultsIn mid-systole, the normal TA area was 9.2 ± 2.0 cm2 for men and 7.4 ± 1.6 cm2 for women. When indexed to body surface area (BSA), there were no significant differences in the 3D parameters between genders. The 2D TA diameters were smaller than those measured in 3D. The ROC curve analysis identified that all 3D TA parameters can accurately differentiate between different functional TR grades. Additionally, the optimal cut-off values were identified for each TA parameter.ConclusionsGender, body size, and age have an impact on the TA parameters in healthy subjects. 2D measurements are smaller than 3D parameters. The reference values for 3D metrics according to TR severity can help in identifying TA dilation and distinguishing between different functional TR grades.
