TRI-SCORE and benefit of intervention in patients with severe tricuspid regurgitation.

BACKGROUND AND AIMS: Benefit of tricuspid regurgitation (TR) correction and timing of intervention are unclear. This study aimed to compare survival rates after surgical or transcatheter intervention to conservative management according to a TR clinical stage as assessed using the TRI-SCORE. METHODS: A total of 2,413 patients with severe isolated functional TR were enrolled in TRIGISTRY (1217 conservatively managed, 551 isolated tricuspid valve surgery, and 645 transcatheter valve repair). The primary endpoint was survival at 2 years. RESULTS: The TRI-SCORE was low (≤3) in 32%, intermediate (4-5) in 33%, and high (≥6) in 35%. A successful correction was achieved in 97% and 65% of patients in the surgical and transcatheter groups, respectively. Survival rates decreased with the TRI-SCORE in the three treatment groups (all P < .0001). In the low TRI-SCORE category, survival rates were higher in the surgical and transcatheter groups than in the conservative management group (93%, 87%, and 79%, respectively, P = .0002). In the intermediate category, no significant difference between groups was observed overall (80%, 71%, and 71%, respectively, P = .13) but benefit of the intervention became significant when the analysis was restricted to patients with successful correction (80%, 81%, and 71%, respectively, P = .009). In the high TRI-SCORE category, survival was not different to conservative management in the surgical and successful repair group (61% and 68% vs 58%, P = .26 and P = .18 respectively). CONCLUSIONS: Survival progressively decreased with the TRI-SCORE irrespective of treatment modality. Compared to conservative management, an early and successful surgical or transcatheter intervention improved 2-year survival in patients at low and, to a lower extent, intermediate TRI-SCORE, while no benefit was observed in the high TRI-SCORE category.

Assessing sleep-related breathing disorders among newly diagnosed rheumatoid and psoriatic arthritis patients: a cross-sectional study.

OBJECTIVES: This cross-sectional study aimed to determine the prevalence and risk factors for sleep-related breathing disorders (SRBD) in newly diagnosed, untreated rheumatoid arthritis (RA) and psoriatic arthritis (PsA) patients, and to develop a screening algorithm for early detection. METHODS: We evaluated newly diagnosed RA or PsA patients using the Epworth Sleepiness Scale (ESS) questionnaire, cardiorespiratory polygraphy (RPG), and clinical and laboratory assessments. Sleep apnea syndrome (SAS) was diagnosed based on pathological RPG findings excessive daytime sleepiness, defined as ESS score above 10. RESULTS: The study included 39 patients (22 RA, 17 PsA) and 23 controls. In RPG, SRBD was identified in 38.5% of arthritis patients compared to 39.1% of controls (p = 1.00), with male gender (p = .004) and age (p < .001) identified as risk factors. Excessive daytime sleepiness was noted in 36.4% of RA patients, 17.6% of PsA patients, and 21.7% of controls. Of the 24 patients diagnosed with SRBD, 41.6% met the criteria for SAS. SAS prevalence was 31.8% among RA patients, 0% in PsA patients, and 13% in controls. A significant association was observed between excessive daytime sleepiness and SRBD (p = .036). CONCLUSION: Our findings reveal a high prevalence of SRBD in newly diagnosed, untreated RA and PsA patients in ESS and RPG, with excessive daytime sleepiness being a reliable predictor of SRBD. Patients with RA exhibited a higher predisposition to SAS. We therefore suggest incorporating ESS and RPG as screening tools in RA or PsA for early detection and management of SRBD.

Development and Validation of the Trait Sexual Motivation Scale (TSMS).

Sexual motivation, the interest in sexual activity, affects people's thinking, feeling, and behavior. Common scales used to assess sexual motivation suffer from drawbacks that limit their validity and applicability. We therefore developed and validated the Trait Sexual Motivation Scale (TSMS), a brief, theory-driven self-report scale, over the course of four preregistered studies (Ntotal = 2,083). Results indicated good model fit, high internal consistency and stability of the second-order (i.e., trait sexual motivation) and first-order (i.e., cognition, affect, behavior) factor scores, and scalar measurement invariance for gender and relationship status. The TSMS correlated as expected with sexual and non-sexual constructs and predicted sexual outcomes cross-sectionally and prospectively in everyday life. Overall, the TSMS emerged as an economical, reliable, and valid measure of sexual motivation.

Mortality prediction of the frailty syndrome in patients with severe mitral regurgitation.

In this prospective observational study, we investigated the impact of geriatric syndromes and frailty on mortality and evaluated the prognostic value of different frailty, nutritional, and geriatric assessment tools in high-risk patients with severe mitral valve regurgitation (MR) who were evaluated for mitral valve therapies including surgical, interventional, and conservative treatment options. We prospectively assessed multiple parameters including the CONUT Score, the Katz Index of independence in activities of daily living (ADL), the Fried Frailty Phenotype (FFP), and the Essential Frailty Toolset (EFT) Score in 127 patients with severe symptomatic MR requiring surgical/interventional treatment versus conservative monitoring. We compared their predictive value on mortality including multivariate regression analysis to identify the most suitable tool to predict outcomes in these patient groups. The frailty syndrome as assessed with the CONUT Score, Katz Index, EFT Score, and FFP was associated with higher rates of comorbidities, significantly higher risk scores such as logistic EuroSCORE, EuroSCORE II, and STS-PROM, and significantly higher mortality rates. The EFT Score and FFP were independent predictors of one-year all-cause mortality in our study cohort (EFT Score: HR 1.9, 95% CI 1.2 to 3.2; p = 0.01; FFP: HR 1.8, 95% CI 1.1 to 3.1; p = 0.015). Geriatric syndromes and frailty are associated with increased mortality in high-risk patients with symptomatic severe MR. The EFT Score and the FFP were independent predictors of one-year all-cause mortality.

Prevalence of sleep-disordered breathing in patients with mitral regurgitation and the effect of mitral valve repair.

PURPOSE: The relationship between chronic heart failure and sleep-disordered breathing (SDB) has been frequently described. However, little is known about the association of mitral regurgitation (MR) and SDB or the impact of transcatheter mitral valve repair (TMVR) on SDB. Our aims were first to determine the prevalence of SDB in patients with MR, and second to determine the effect of TMVR on SDB. METHODS: Patients with MR being evaluated for TMVR at the University Hospital Bonn underwent polygraphy (PG) to determine the prevalence of SDB. After TMVR, a subset of patients was followed up with transthoracic echocardiography (TTE) and PG to evaluate the effect of TMVR on SDB. RESULTS: In 53 patients, mean age was 76.0 ± 8.5 years and 62% were male. Patients predominantly had more than moderate mitral regurgitation (94%). SDB was highly prevalent (68%) with predominantly central sleep apnoea (CSA, 67%). After TMVR in 15 patients, the apnoea/hypopnoea index (AHI) and central apnoea index (AI) were significantly reduced among patients with SDB (AHI - 8.0/h, p = 0.021; central AI - 6.9/h, p = 0.046). The left atrial volume index (LAVI) at baseline was significantly higher in patients with CSA than in patients with obstructive sleep apnoea (OSA) and was significantly reduced after TMVR (63.5 ml/m2 ± 27.2 vs. 38.3 ml/m2 ± 13.0; - 18.4 ml/m2, p = 0.027). CONCLUSION: SDB, especially CSA, is highly prevalent in patients with mitral regurgitation. In the follow-up cohort TMVR led to a significant reduction of the AHI, predominantly of central events. The findings of the study suggest that TMVR may be a suitable therapy not only for MR but also for the accompanying CSA. LAVI may be a useful indicator for CSA in patients with MR.

High prevalence of peripheral and carotid artery disease in patients with interstitial lung diseases.

Background: Interstitial lung diseases (ILD) are a heterogenous group of diseases, which have pulmonary fibrosis, restrictive lung disease, and decreased diffusion capacity as a common final path. Premature death frequently results not from ILD itself but from comorbidities. Peripheral artery disease (PAD) is a common comorbid disease in different chronic lung diseases. The focus of the present study is to clarify the prevalence of PAD in ILD. Patients and methods: A total of 97 patients with ILD and 30 controls were included in the study. Patients with ILD were subdivided into two groups according to the progression of pulmonary fibrosis: progressive fibrosing and non-progressive fibrosing ILD (PF-ILD and nPF-ILD, respectively). All participants underwent standard angiological and pneumological diagnostic procedures including six-minute walking test, measurement of ankle-brachial-index, and colour-coded duplex sonography. Results: We observed no relevant differences in the baseline characteristics except age. Both, PF-ILD and nPF-ILD patients, presented with a highly increased incidence of atherosclerotic lesions compared to the control group (p<0.001). PAD was present in all patients with PF-ILD and in 73% of patients with nPF-ILD. These results were confirmed by age-adjusted regression analyses. Conclusions: The present results indicate that ILD is an independent risk factor for atherosclerosis. Patients with PF-ILD are more severely affected than nPF-ILD patients with age as a confounding variable. Atherogenesis in ILD may be mediated by increased cardiovascular risk, systemic inflammation and chronic hypoxemia.

Frailty, malnutrition, and the endocrine system impact outcome in patients undergoing aortic valve replacement.

BACKGROUND: Frailty is a multidimensional syndrome that affects mortality after aortic valve replacement (AVR). Malnutrition is often associated with the development of frailty. However, data regarding the association of frailty with nutritional status and underlying endocrinological dysregulation in patients with severe aortic valve stenosis are limited. OBJECTIVES: We aimed to systematically screen for frailty and malnutrition, to evaluate for underlying endocrinological disorders and inflammation, and to assess the ability of these parameters to predict outcomes after AVR. METHODS: Our study included 373 patients undergoing transcatheter and surgical AVR. Frailty was assessed using the Fried Frailty Phenotype (FFP), Essential Frailty Toolset, Lawton-Brody, and Katz Index. Malnutrition was measured using the Mini Nutritional Assessment (MNA-LF) and Controlling Nutritional Status. Outcomes of interest were 30-day and one-year mortality. RESULTS: The prevalence of frailty ranged from 6.4% to 65.7% and malnutrition from 5.9% to 10.5%, depending on the evaluation tool. Both parameters were associated with higher levels of cortisol and parathormone as well as lower levels of IGF-1, testosterone, DHEAS, and c-reactive protein. Malnutrition was associated with increased 30-day mortality, and both frailty and malnutrition with increased one-year mortality. In a multivariate analysis, malnutrition measured by the MNA-LF (OR: 2.32 [95%CI: 1.19-4.53], p = 0.01) and frailty as assessed by the FFP (OR: 1.42 [95%CI: 1.02-1.96], p = 0.03) were independent predictors of one-year mortality. CONCLUSION: The prevalence of frailty and malnutrition varies significantly depending on the assessment tool. Both syndromes share common endocrinological alterations. Frailty and malnutrition are independent risk factors for mortality after AVR.

A simplified cardiac damage staging predicts the outcome of patients undergoing TAVR-A multicenter analysis.

BACKGROUND: A significant number of patients with severe aortic stenosis (AS) undergoing transcatheter aortic valve replacement (TAVR) suffer from extra-aortic cardiac damage. Few studies have investigated strategies to quantify cardiac damage and stratify patients accordingly in different risk groups. The aim of this retrospective multicenter study was to provide a user-friendly simplified staging system based on the proposed classification system of Généreux et al. as a tool to evaluate the prognosis of patients undergoing TAVR more easily. Moreover, we analyzed changes in cardiac damage after TAVR. METHODS: We assessed cardiac damage in patients, who underwent TAVR at the Heart Center Bonn or Düsseldorf, using pre- and postprocedural transthoracic echocardiography. Patients were assigned to the staging system proposed by Généreux et al. according to the severity of their baseline cardiac damage. Based on the established system, we created a simplified staging system to facilitate improved applicability. Finally, we compared clinical outcomes between the groups and evaluated changes in cardiac damage after TAVR. RESULTS: A total of 933 TAVR patients were included in the study. We found a significant association between cardiac damage and 1-year all-cause mortality (stage 0: 0% vs. stage 1: 3% vs. stage 2: 6.6%; p < 0.009). In multivariate analysis, cardiac damage was an independent predictor of 1-year all-cause mortality (hazard ratio: 2.0, 95% confidence interval: 1.1-3.8; p = 0.03). CONCLUSIONS: In patients undergoing TAVR, cardiac damage is associated with enhanced mortality. A simplified staging system can help identify patients at high risk for an adverse outcome.

Transcatheter valve repair of tricuspid regurgitation with the PASCAL system: TriCLASP study 30-day results.

BACKGROUND: Severe tricuspid regurgitation (TR) is independently associated with increased morbidity and mortality. Percutaneous transcatheter approaches may offer an alternative for patients not amenable to surgery. METHODS: TriCLASP is a prospective, single-arm, multicenter European post-market clinical follow-up study (NCT04614402) to evaluate the safety and performance of the PASCAL system (Edwards Lifesciences) in patients with severe or greater TR. At 30 days, a composite of major adverse events (MAEs) adjudicated by a clinical events committee, echocardiographic parameters adjudicated by core laboratory, and clinical, functional, and quality-of-life measures were evaluated. RESULTS: Mean age of the 74 enrolled patients was 80.3 years, with 58.1% female, 90.5% systemic hypertension, and 77.0% in New York Heart Association (NYHA) class III/IV. Mean Society for Thoracic Surgeons score (MV repair) was 9.0%. TR severity was significantly reduced at discharge (p < 0.001) and sustained at 30 days (p < 0.001), and 90.0% of patients achieved ≤moderate TR. The composite MAE rate at 30 days was 3.0%, including 4 events in 2 patients: cardiovascular mortality 1.5%, stroke 1.5%, renal complications requiring unplanned dialysis or renal replacement therapy 1.5%, and severe bleeding 1.5%. There were no nonelective tricuspid valve reinterventions, major access site and vascular complications, major cardiac structural complications, or device embolizations. NYHA class I/II was achieved in 55.8%, 6-minute walk distance improved by 38.2 m (p < 0.001), and Kansas City cardiomyopathy questionnaire scores improved by 13.4 points (p < 0.001). CONCLUSION: Experience with the PASCAL transcatheter valve repair system in a European post-market setting confirms favorable safety and effectiveness at 30 days. TR significantly reduced, and clinical, functional, and quality-of-life outcomes significantly improved. This study is ongoing. Clinical Trial Registration: The study is ongoing and registered on ClinicalTrials.gov as NCT04614402. The current analysis is an interim report.

Percutaneous trans-axilla transcatheter aortic valve replacement.

The left axillary artery is an attractive alternative access route for transcatheter aortic valve replacement (TAVR) and may provide better outcomes compared to other alternatives. Nevertheless, there remain concerns about vascular complications, lack of compressibility, and thorax-related complications. Between March 2019 and March 2021, 13 patients underwent transaxillary TAVR for severe aortic stenosis at the University Hospital Bonn. The puncture was performed with a puncture at the distal segment of the axillary artery through the axilla, with additional femoral access for applying a safety wire inside the axillary artery. Device success was defined according to the VARC 2 criteria. The study participants were advanced in age (77 ± 9 years old), and 54% were female, with an intermediate risk for surgery (STS risk score 4.7 ± 2.0%). The average diameter of the distal segment of the axillary artery was 5.8 ± 1.0 mm (i.e., the puncture site) and 7.6 ± 0.9 mm for the proximal axillary artery. Device success was achieved in all patients. 30-day major adverse cardiac and cerebrovascular events were 0%. With complete percutaneous management, stent-graft implantation was performed at the puncture site in 38.5% of patients. Minor bleeding was successfully managed with manual compression. Moreover, no thorax-related complications, hematomas, or nerve injuries were observed. Percutaneous trans-axilla TAVR was found to be feasible and safe. This modified approach may mitigate the risk of bleeding and serious complications in the thorax and be less invasive than surgical alternatives.

Incidence, persistence, and clinical relevance of iatrogenic atrial septal defects after percutaneous left atrial appendage occlusion.

OBJECTIVE: To investigate the rate and clinical impact of a persisting iatrogenic atrial septal defect (iASD) after percutaneous left atrial appendage occlusion (LAAO). BACKGROUND: Percutaneous LAAO is an alternative to oral anticoagulation (OAC) for the prevention of ischemic stroke and systemic embolism in patients with atrial fibrillation (AF). Data regarding incidence and persistence of iASD after LAAO procedures and its clinical relevance is scarce. METHODS: We retrospectively analyzed 144 patients that underwent LAAO at our center between 2009 and 2020 who had at least one follow-up including transesophageal echocardiography (TEE). Baseline clinical, procedural data and echocardiographic characteristics in patients with and without evidence of an iASD were compared. We furthermore determined the rate of iASD persistence over time and evaluated outcomes of patients with and without spontaneous iASD closure. RESULTS: After a median of 92 days (IQR 75-108 days) after LAAO, 50 patients (50/144, 34.7%) showed evidence of an iASD. Patients with iASD had higher CHADS-VASc-scores (4.9±1.5 vs 4.2±1.2, p = 0.03), larger left atrial volumes (80.5±30.5 ml vs 67.1±19.7 ml, p = 0.01) and were more likely to have relevant mitral regurgitation (≥° II) (46.0% vs 12.3%, p = 0.001). LAAO procedures took longer (50.1±24.3 vs 41.1±17.8 min, p = 0.06) in patients with a persisting iASD. Furthermore, larger device sizes were implanted (24.3±3.4 mm vs 22.1±2.8 mm, p = 0.03). The presence of an iASD had no impact on RV dysfunction, thromboembolism or mortality. Spontaneous closure of an iASD was documented in 52.0% (26/50). Hereby, similar risk factors were identified for the persistence of an iASD in follow-up.

QRS duration is a risk indicator of adverse outcomes after MitraClip.

BACKGROUND: While QRS duration is a known marker of left ventricular (LV) function, little is known about its utility for predicting clinical prognosis after transcatheter mitral valve repair (TMVR). We investigated the association between QRS duration and one-year adverse events after TMVR with the MitraClip system. METHODS: From January 2011 through April 2019, we identified consecutive patients who underwent TMVR. Patients who had prior cardiac resynchronization therapy or a ventricular pacing rhythm were excluded. The patients were divided into two groups according to their QRS duration (<120 or ≥ 120 ms). Cox proportional hazard model was applied to determine the association between QRS duration and the composite outcome (all-cause mortality and re-hospitalization due to heart failure) within 1 year. RESULTS: A total of 348 patients were analyzed. Prolonged QRS duration (≥120 ms) was associated with an increased risk of the composite outcome (adjusted-HR 2.35, 95%CI 1.30-4.24, p = .005). There was a linear relationship between prolonged QRS duration and the increased risk of the composite outcomes. The observed association was consistent both in patients with left ventricular ejection fraction ≤35% and those with >35%. Furthermore, a QRS duration ≥120 ms was associated with lower improvement of LVEF at follow-up (adjusted-ß coefficient - 5.31%, 95%CI -8.17 to -2.46, p < .001). CONCLUSIONS: Prolonged QRS duration was associated with an increased risk of mortality and re-hospitalization and less improvement of LVEF following TMVR. QRS duration could be a useful marker to predict adverse outcomes and LV function after TMVR.

Association of heart failure duration with clinical outcomes after transcatheter mitral valve repair for functional mitral regurgitation.

BACKGROUND: Little is known about the association of heart failure (HF) chronicity with clinical outcomes after transcatheter mitral valve repair (TMVR) for functional mitral regurgitation (MR). METHODS: From January 2011 to March 2019, consecutive patients with functional MR who underwent a MitraClip procedure were analyzed. The patients were divided into two groups according to HF duration-those with duration ≤18 months and those with >18 months. The primary outcome measure was a composite of all-cause mortality and re-HF rehospitalization within 1 year after the procedure. These outcomes were also assessed separately. A Cox proportional hazard model was conducted for investigating the association of HF duration with the primary outcome. RESULTS: A total of 208 patients were analyzed. Patients with HF duration >18 months had a higher rate of the primary outcome compared to those with HF duration ≤18 months (38.1 vs. 19.0%, log-rank p = .003). A longer duration of HF was associated with an increased risk of the primary outcomes (adjusted-HR of >18 months, 2.12 95% CI, 1.14-4.19; p = .03; adjusted-HR (hazard ratios) for 1 year increase, 1.05; 95% CI, 1.02-1.09; p = .004). The association of HF duration with the primary outcomes showed a steep rise during the first 2 years of HF duration and progressive increase after 5 years. CONCLUSIONS: A longer HF duration before TMVR was associated with an increased risk of all-cause mortality or HF rehospitalization. HF duration can be used for the risk stratification marker in patients undergoing TMVR for functional MR.

12-Month outcomes of transcatheter tricuspid valve repair with the PASCAL system for severe tricuspid regurgitation.

OBJECTIVES: We investigated the durability of tricuspid regurgitation (TR) reduction and the clinical outcomes through 12 months after transcatheter tricuspid valve repair (TTVr) with the PASCAL Transcatheter Valve Repair System. BACKGROUND: TTVr has rapidly developed and demonstrated favorable acute outcomes, but longer follow-up data are needed. METHODS: Overall, 30 patients (age 77 ± 6 years; 57% female) received PASCAL implantation from September 2017 to May 2019 and completed a clinical follow-up at 12 months. RESULTS: The TR etiology was functional in 25 patients (83%), degenerative in three (10%), and mixed in two (7%). All patients had TR severe or greater (massive or torrential in 80%) and heart failure symptoms (90% in NYHA III or IV) under optimal medical treatment. Single-leaflet device attachment occurred in two patients. Moderate or less TR was achieved in 23/28 patients (82%) at 30 days, which was sustained at 12 months (86%). Two patients underwent repeat TTVr due to residual torrential TR (day 173) and recurrence of severe TR (day 280), respectively. One-year survival rate was 93%; 6 patients required rehospitalization due to acute heart failure. NYHA functional class I or II was achieved in 90% and 6-minute walk distance improved from 275 ± 122 m at baseline to 347 ± 112 m at 12-month (+72 ± 82 m, p < .01). There was no stroke, endocarditis, or device embolization during the follow-up. CONCLUSIONS: Twelve-month outcomes from this multicenter compassionate use experience with the PASCAL System demonstrated high procedural success, acceptable safety, and significant clinical improvement.

Prognostic significance of the get with the guidelines-heart failure (GWTG-HF) risk score in patients undergoing trans-catheter tricuspid valve repair (TTVR).

The Get-With-The-Guidelines-Heart-Failure (GWTG-HF) score is a risk assessment tool to predict mortality in patients with heart-failure (HF). We aimed to evaluate the GWTG-HF score for risk stratification in HF patients with tricuspid regurgitation undergoing trans-catheter tricuspid valve repair (TTVR). In total, 181 patients who underwent TTVR via edge-to-edge repair (86%) or annuloplasty (14%) were enrolled. Patients were categorized into a low- (≤ 43 points), intermediate- (44-53 points) and high-risk score groups (≥ 54 points). TTVR led to an improvement of TR (p < 0.0001) and NYHA (p < 0.0001). Kaplan-Meier analysis and log-rank test revealed that higher GWTG-HF scores were associated with reduced rates of event-free survival regarding mortality (96% vs 89% vs 73%, respectively, p = 0.001) and hospitalization for heart failure (HHF) (89% vs 86% vs 74%, respectively, p = 0.026). After adjusting for important variables like renal function, left ventricular ejection fraction and mitral regurgitation, the GWTG-HF score remained an independent predictor of the composite endpoint of HHF or mortality (hazard ratio 1.04 per 1-point increase, p = 0.029). Other remaining predictors were renal function and mitral regurgitation. The GWTG-HF score used as a risk stratification tool of mortality and HHF maintains its prognostic value in a HF population with severe TR undergoing TTVR.

The predictive value of intraprocedural mitral gradient for outcomes after MitraClip and its peri-interventional dynamics.

BACKGROUND: The current data on the impact of the increased mitral gradient (MG) on outcomes are ambiguous, and intraprocedural assessment of MG can be challenging. Therefore, we aimed to evaluate (a) peri-interventional dynamics of MG, (b) the impact of intraprocedural MG on clinical outcomes, and (c) predictors for unfavorable MG values after MitraClip. METHODS: We prospectively included patients who underwent MitraClip. All patients underwent echocardiography at baseline, intraprocedurally, at discharge, and after 6 months. 12-month survival was documented. RESULTS: One hundred and seventy five patients (age 81.2 ± 8.2 years, 61.2% male) with severe mitral regurgitation (MR) were included. We divided our cohort into two groups according to intraprocedural MG with a threshold of 4.5 mm Hg, determined by a multivariate analysis of predictors for 12-month mortality (<4.5 mm Hg: Group 1, ≥4.5 mm Hg: Group 2). Intraprocedural MG ≥4.5 mm Hg was found to be the strongest independent predictor for 12-month mortality (HR: 2.33, P = .03, OR: 1.70, P = .05), and >3.9 mm Hg was associated with adverse functional outcomes (OR: 1.96, P = .04). The baseline leaflet-to-annulus index >1.1 was found to be the strongest independent predictor (OR: 9.74, P = .001) for unfavorable intraprocedural MG, followed by the number of implanted clips (P = .01), MG at baseline (P = .02), and central clip implantation (P = .05). CONCLUSION: An intraprocedural MG <3.9 mm Hg appears to be the best strategy for 1-year survival and favorable functional outcomes after edge-to-edge MV repair with MitraClip independently from MR etiology. Peri-interventional echocardiographic and procedural parameters are useful for the adequate assessment of intraprocedural MG.

Transcatheter edge-to-edge repair for reduction of tricuspid regurgitation: 6-month outcomes of the TRILUMINATE single-arm study.

BACKGROUND: Tricuspid regurgitation is a prevalent disease associated with high morbidity and mortality, with few treatment options. The aim of the TRILUMINATE trial is to evaluate the safety and effectiveness of TriClip, a minimally invasive transcatheter tricuspid valve repair system, for reducing tricuspid regurgitation. METHODS: The TRILUMINATE trial is a prospective, multicentre, single-arm study in 21 sites in Europe and the USA. Patients with moderate or greater triscuspid regurgitation, New York Heart Association class II or higher, and who were adequately treated per applicable standards were eligible for enrolment. Patients were excluded if they had systolic pulmonary artery pressure of more than 60 mm Hg, a previous tricuspid valve procedure, or a cardiovascular implantable electronic device that would inhibit TriClip placement. Participants were treated using a clip-based edge-to-edge repair technique with the TriClip tricuspid valve repair system. Tricuspid regurgitation was graded using a five-class grading scheme (mild, moderate, severe, massive, and torrential) that expanded on the standard American Society of Echocardiography grading scheme. The primary efficacy endpoint was a reduction in tricuspid regurgitation severity by at least one grade at 30 days post procedure, with a performance goal of 35%, analysed in all patients who had an attempted tricuspid valve repair procedure upon femoral vein puncture. The primary safety endpoint was a composite of major adverse events at 6 months, with a performance goal of 39%. Patients were excluded from the primary safety analysis if they did not reach 6-month follow-up and did not have a major adverse event during previous follow-ups. The trial has completed enrolment and follow-up is ongoing; it is registered with ClinicalTrials.gov, number NCT03227757. FINDINGS: Between Aug 1, 2017, and Nov 29, 2018, 85 patients (mean age 77·8 years [SD 7·9]; 56 [66%] women) were enrolled and underwent successful TriClip implantation. Tricuspid regurgitation severity was reduced by at least one grade at 30 days in 71 (86%) of 83 patients who had available echocardiogram data and imaging. The one-sided lower 97·5% confidence limit was 76%, which was greater than the prespecified performance goal of 35% (p<0·0001). One patient withdrew before 6-month follow-up without having had a major adverse event and was excluded from analysis of the primary safety endpoint. At 6 months, three (4%) of 84 patients experienced a major adverse event, which was less than the prespecified performance goal of 39% (p<0·0001). Single leaflet attachment occurred in five (7%) of 72 patients. No periprocedural deaths, conversions to surgery, device embolisations, myocardial infarctions, or strokes occurred. At 6 months, all-cause mortality had occurred in four (5%) of 84 patients. INTERPRETATION: The TriClip system appears to be safe and effective at reducing tricuspid regurgitation by at least one grade. This reduction could translate to significant clinical improvement at 6 months post procedure. FUNDING: Abbott.

Impact of combined baseline and postprocedural troponin values on clinical outcome following the MitraClip procedure.

OBJECTIVES: The purpose of this study was to investigate the impact of periprocedural troponin levels on clinical outcome following the MitraClip procedure. BACKGROUND: Cardiac troponin is known to be a predictive biomarker for various clinical outcomes; however, data about its predictive value in patients undergoing transcatheter mitral valve repair are limited. METHODS: Consecutive patients undergoing the MitraClip procedure were enrolled. Serum cardiac troponin I concentrations were measured before and after the procedure, and the maximal value recorded within 72 hr after the procedure was used for the postprocedural values. The clinical outcome was all-cause mortality within a 1-year follow-up. RESULTS: Out of 354 patients, 29 patients (8.2%) were deceased within 1 year. Patients who died had significantly higher baseline (0.05 [0.01-0.08] vs. 0.01 [0.01-0.03] ng/ml; p < .001) and postprocedural troponin I values (0.51 [0.30-1.42] vs. 0.20 [0.33-0.55] ng/ml; p = .005). A Kaplan-Meier analysis showed that patients with higher baseline troponin I values had a significantly worse prognosis than those with lower values (log-rank p < .001), and similarly, 1-year mortality was significantly higher in patients with higher postprocedural troponin I than those with lower levels (log-rank p = .021). Moreover, the highest mortality rate was observed in patients with both elevated baseline and postprocedural troponin I values (log-rank p = .001), which was found to be an independent predictor of mortality by multivariable analyses. CONCLUSIONS: The present study suggests that combined baseline and postprocedural troponin measurements are useful for risk stratification of 1-year mortality following the MitraClip procedure.

TAVR outcome after reclassification of aortic valve stenosis by using a hybrid continuity equation that combines computed tomography and echocardiography data.

BACKGROUND: In the continuity equation, assumption of a round-shaped left ventricular outflow tract (LVOT) leads to underestimation of the true aortic valve area in two-dimensional echocardiography. The current study evaluated whether inclusion of the LVOT area, as measured by computed tomography (CT), reclassifies the degree of aortic stenosis (AS) and assessed the impact on patient outcome after transcatheter aortic valve replacement (TAVR). METHODS AND RESULTS: Four hundred and twenty-two patients with indexed aortic valve area index (AVAi) of <0.6 cm2 /m2 , assessed by using the classical continuity equation (mean age: 81.5 ± 6.1 years, 51% female, mean left ventricular ejection fraction: 53.2 ± 13.6%), underwent TAVR and were included. After inclusion of the CT measured LVOT area into the continuity equation, the hybrid AVAi led to a reclassification of 30% (n = 128) of patients from severe to moderate AS. Multivariate predictors for reclassification were male sex, lower mean aortic gradient, and lower annulus/LVOT ratio (all p < .01). Reclassified patients had significantly higher sST2 at baseline and higher NT-proBNP values at baseline and 6 months follow-up compared to non-reclassified patients. Acute kidney injury was experienced more frequently after TAVR by reclassified patients, but no significant mortality difference occurred during 2 years of follow-up. CONCLUSION: The hybrid AVAi reclassifies a significant portion of low-gradient severe AS patients into moderate AS. Reclassified patients showed increased fibrosis and heart failure markers at baseline compared to non-reclassified patients. But reclassification had no significant impact on mortality up to 2 years after TAVR. Routine assessment of hybrid AVAi seems not to improve further risk stratification of TAVR patients.
