RESUMO
BACKGROUND: Tricuspid valve transcatheter edge-to-edge repair has emerged as a valuable treatment option for patients with severe tricuspid regurgitation (TR). OBJECTIVES: This study aims to investigate the safety and effectiveness of the PASCAL transcatheter valve repair system in treating severe TR in a real-world patient population. METHODS: The PASTE (PASCAL for Tricuspid Regurgitation-a European registry) study is an investigator-initiated, multicenter, retrospective, and prospective observational cohort analysis conducted across 16 European heart valve centers including consecutive patients treated with the PASCAL transcatheter valve repair system from February 2019 to November 2023. Echocardiographic assessments were performed at baseline, discharge, and follow-up, and were subjected to centralized analysis. RESULTS: The study included 1,059 high-risk patients (mean age 79 ± 9 years; 53% female; TRI-SCORE risk 23% ± 18%; 87% NYHA functional class III/IV) with multiple comorbidities. Severe or higher graded TR was observed in 96% of patients. Intraprocedural success according to Tricuspid Valve Academic Research Consortium criteria was achieved in 85%, and TR reduced to ≤moderate in 87%. Independent predictors for a postprocedure residual TR of >moderate were coaptation gaps ≥8 mm (OR: 1.67; 95% CI: 1.03-2.72; P = 0.038), tenting height ≥10 mm (OR: 2.18; CI: 1.30-3.65; P = 0.003), the presence of a transvalvular lead (OR: 1.91; 95% CI: 1.19-3.05; P = 0.007), right ventricular dilatation >42 mm (OR: 3.35; 95% CI: 1.37-9.1; P = 0.009) and massive/torrential TR at baseline (OR: 4.59; 95% CI: 2.35-8.96; P < 0.001). At 1 year, 83% of patients showed ≤moderate TR. Significant clinical improvements included enhanced NYHA functional class (66% class I/II vs 17% at baseline; P < 0.001). Patients treated with the first-generation PASCAL system (n = 570) and with the new PASCAL Precision system (n = 489) had similar clinical profiles and TR severity at baseline. However, the Precision cohort showed greater TR reduction to trace/mild (63% vs 49%; P < 0.001), shorter procedure times (median 93 minutes [Q1-Q3: 69-130 minutes] vs 120 minutes [Q1-Q3: 82-165 minutes]; P < 0.001), and higher clinical success rates according to the Tricuspid Valve Academic Research Consortium at 30 days and 1 year (87% vs 81% [P = 0.021] and 56% vs 50% [P = 0.044], respectively). Higher center experience (≥21 patients/year) resulted in higher intraprocedural and clinical success. CONCLUSIONS: The PASCAL system effectively treats severe TR in high-risk patients, offering sustained TR reduction and significant clinical improvements at 1-year follow-up.

RESUMO
BACKGROUND: Transcatheter tricuspid valve intervention (TTVI) has shown promising results with persistent reduction of tricuspid regurgitation (TR) and improvements in functional class and quality of life (QOL). OBJECTIVES: To analyze the impact of TTVI on maximal and submaximal exercise capacity (SEC). METHODS: Constant work-rate exercise-time (CWRET) testing reflects SEC, which is more likely to be relevant for daily life activities and provides more differentiated physiological insight into the nature of exercise intolerance. Thus, 30 patients undergoing TTVI (21 direct annuloplasty and 9 edge-to-edge repair) received cardiopulmonary exercise testing (CPET) and CWRET (at 75% of maximum work rate in the initial CPET) before and 3 months after TTVI. RESULTS: Patients' age was 80.5 [74.8-82.3] years and 53.3% were female. TR reduction ≥ 2 grades was achieved in 93.3% (TR grade ≤ moderate in 83.3%). Echocardiography revealed improved right ventricular (RV) characteristics with decreased RV basal diameter (47.0 mm [43.0-54.3] vs. 41.5 mm [36.8-48.0]; p < 0.001) and decreased inferior caval vein diameter. CWRET testing showed a significantly improved SEC (246.5 s [153.8-416.8] vs. 338.5 s [238.8-611.8] p = 0.001). Maximum oxygen uptake showed a positive trend without statistically significant differences (9.9 ml/min/kg [8.6-12.4] vs. 11.7 ml/min/kg [9.7-13.3]; p = 0.31). In contrast to the six-minute-walking distance (6MWD), SEC correlated moderately with effective regurgitation orifice area reduction (r = 0.385; p = 0.036), increased cardiac output (r = 0.378; p = 0.039), and improved QOL (r = 387; p = 0.035). CONCLUSION: Improvements in exercise capacity after TTVI mainly occur in the submaximal rather than in the maximal exercise range and correlate with hemodynamic effects and QOL. This may have a methodological impact on assessment of exercise capacity in these patients.
RESUMO
BACKGROUND AND OBJECTIVE: Within recent years, transcatheter tricuspid edge-to-edge repair (T-TEER) has emerged as a safe and effective treatment option in patients with secondary tricuspid regurgitation (TR). However, for primary TR, data on the robustness and durability of TR reduction 1 year following T-TEER is limited. METHODS: All consecutive patients treated with T-TEER for TR at two high-volume centers between September 2018 and December 2022 were enrolled in a registry. Primary TR was defined as tricuspid valve (TV) prolapse or flail TV leaflets as assessed by pre- and peri-interventional transesophageal echocardiography (TEE). RESULTS: 201 patients were included in this analysis, of whom 27 (13.4%) were classified as primary TR and 174 (86.6%) as TR of secondary origin. All-cause mortality during 1-year follow-up was reached by 50 patients (24.9%) [primary: 7 (25.9%), secondary: 43 (24.7%)], and 151 (75.1%) completed follow-up with transthoracic echocardiography (TTE). Patients' median age was 80 (76-83) years, 112 (55.7%) were female and 181 (90.1%) reported a New-York heart association functional class (NYHA-FC) of III or IV. The remaining baseline clinical and echocardiographic parameters were comparable between the groups, but secondary TR patients had a significantly higher TRI-SCORE (5 (4-8) vs. 7 (5-14), P = 0.010). In both groups, an immediate reduction of TR-Grade post-intervention was observed. This reduction was sustained at follow-up with 80.0% of the primary TR patients classified as moderate or less and 61.8% of the secondary TR patients. This translated to a significant improvement of NHYA-FC in both groups. Kaplan-Meier analysis revealed no differences regarding rates for all-cause mortality between the groups (P < 0.99). CONCLUSION: T-TEER achieves a robust TR reduction in primary TR patients 1 year after intervention with noninferior clinical results to treatment for secondary TR with regards to mortality, re-hospitalization, and NYHA-FC.
RESUMO
BACKGROUND: Left atrial appendage (LAA) amputation performed alongside cardiac surgery has become an increasingly established procedure to reduce stroke risk in patients with atrial fibrillation. As the recommendation levels for LAA amputation continue to rise, ample evidence assessing its perioperative safety and risk factors is of utmost interest. METHODS: All patients who underwent isolated coronary artery bypass grafting (CABG) between 2018 and 2021 at two high-volume centers were retrospectively included in the study. Patients were divided into two groups-the CABG and CABG + LAA groups-based on whether they underwent concomitant LAA amputation. Propensity score matching (PS matching) was applied to ensure comparability between the groups. The primary endpoint was defined as a composite outcome comprising of all-cause mortality, stroke, and reoperation. Secondary endpoints included the components of the primary endpoint, perioperative outcome parameters, transfusion rates, and laboratory parameters. RESULTS: A total of 3904 patients were included with 3038 and 866 in the CABG and CABG + LAA group, respectively. After PS matching each group consisted of 856 patients. The primary endpoint showed no significant differences between the CABG and CABG + LAA group (7.0% vs. 6.5% (OR 0.9 95% CI [0.64; 1.35], p = 0.70)). Similarly, there were no notable differences in the individual components of the composite endpoint: all-cause mortality (p = 0.84), stroke (p = 0.74), and reoperation (p = 0.50). Subgroup results did not show any relevant dissimilarity. CONCLUSION: The concomitant performance of LAA amputation is not associated with worse in-hospital outcomes, as measured by the composite endpoint of all-cause mortality, stroke, and reoperation.
RESUMO
We provide an overview about the current landscape of transcatheter tricuspid valve interventions (TTVI) and summarize recent findings from trials including TRILUMINATE, TRILUMINATE Pivotal, bRIGHT, TRICLASP, TRISCEND, TRISCEND II, TRICUS, and Cardioband TR EFS. These studies have demonstrated the safety and efficacy of TTVI. Yet, they have failed to show a prognostic benefit over conservative treatment. On the other hand, significant improvements in health status assessments have been observed. Assessment of right ventricular (RV) function prior to tricuspid interventions is crucial, as changes in preload and afterload may lead to RV failure which is associated with a high mortality. Therefore, this review emphasizes the impact of TTVIs on quality of life and explores the influence of RV dysfunction on therapeutic success and prognosis.
RESUMO
BACKGROUND: The impact of intraprocedural results following transcatheter edge-to-edge repair (TEER) in primary mitral regurgitation (MR) is controversial. OBJECTIVES: This study sought to investigate the prognostic impact of intraprocedural residual mitral regurgitation (rMR) and mean mitral valve gradient (MPG) in patients with primary MR undergoing TEER. METHODS: The PRIME-MR (Outcomes of Patients Treated With Mitral Transcatheter Edge-to-Edge Repair for Primary Mitral Regurgitation) registry included consecutive patients with primary MR undergoing TEER from 2008 to 2022 at 27 international sites. Clinical outcomes were assessed according to intraprocedural rMR and mean MPG. Patients were categorized according to rMR (optimal result: ≤1+, suboptimal result: ≥2+) and MPG (low gradient: ≤5 mm Hg, high gradient: > 5 mm Hg). The prognostic impact of rMR and MPG was evaluated in a Cox regression analysis. The primary endpoint was 2-year all-cause mortality or heart failure hospitalization. RESULTS: Intraprocedural rMR and mean MPG were available in 1,509 patients (median age = 82 years [Q1-Q3: 76.0-86.0 years], 55.1% male). Kaplan-Meier analysis according to rMR severity showed significant differences for the primary endpoint between rMR ≤1+ (29.1%), 2+ (41.7%), and ≥3+ (58.0%; P < 0.001), whereas there was no difference between patients with a low (32.4%) and high gradient (42.1%; P = 0.12). An optimal result/low gradient was achieved in most patients (n = 1,039). The worst outcomes were observed in patients with a suboptimal result/high gradient. After adjustment, rMR ≥2+ was independently linked to the primary endpoint (HR: 1.87; 95% CI: 1.32-2.65; P < 0.001), whereas MPG >5 mm Hg was not (HR: 0.78; 95% CI: 0.47-1.31; P = 0.35). CONCLUSIONS: Intraprocedural rMR but not MPG independently predicted clinical outcomes following TEER for primary MR. When performing TEER in primary MR, optimal MR reduction seems to outweigh the impact of high transvalvular gradients.

Background/Objectives: Previous trials reported comparable results with PASCAL and earlier MitraClip generations. Limited comparative data exist for more contemporary MitraClip generations, particularly the large MitraClip XT(R/W). We aimed to evaluate acute and 30-day outcomes in patients undergoing mitral valve transcatheter edge-to-edge repair (M-TEER) with one of the large devices, either PASCAL P10 or MitraClip XT(R/W) (3rd/4th generation). Methods: A total of 309 PASCAL-treated patients were matched by propensity score to 253 MitraClip-treated patients, resulting in 200 adequately balanced pairs. Procedural, clinical, and echocardiographic outcomes were collected for up to 30 days, including subgroup analysis for mitral regurgitation (MR) etiologies. Results: PASCAL and MitraClip patients were comparable regarding age (80 vs. 79 years), sex (female: 45.5% vs. 50.5%), and MR etiology (degenerative MR: n = 94, functional MR [FMR]: n = 96, mixed MR: n = 10 in each group). Technical success rates were comparable (96.5% vs. 96.0%; p > 0.999). At discharge, the mean gradient was higher (3.3 mmHg vs. 3.0 mmHg; p = 0.038), and the residual mitral valve orifice area was smaller in MitraClip patients (3.0 cm2 vs. 2.3 cm2; p < 0.001). At discharge, the reduction to MR ≤ 2+ was comparable (92.4% vs. 87.8%; p = 0.132). However, reduction to MR ≤ 1+ was more frequently observed in PASCAL patients (67.7% vs. 56.6%; p = 0.029), driven by the FMR subgroup (74.0% vs. 60.0%; p = 0.046). No difference was observed in 30-day mortality (p = 0.204) or reduction in NYHA-FC to ≤II (p > 0.999). Conclusions: Both M-TEER devices exhibited high and comparable rates of technical success and MR reduction to ≤2+. PASCAL may be advantageous in achieving MR reduction to ≤1+ in patients with FMR.
RESUMO
Background: Postoperative Atrial Fibrillation (POAF) is a common complication in cardiac surgery. Despite its multifactorial origin, the left atrial (LA) size is closely linked to POAF, raising the question of a valid cut-off value and its impact on the long-term outcome. Methods: Patients without a history of AF who underwent coronary artery bypass grafting between 2014 and 2016 were selected for this retrospective study. LA size was preoperatively assessed using the left atrial anterior-posterior diameter (LAAPd). Correlation and logistic regression analyses were performed, following a receiver-operating characteristic (ROC) analysis. Propensity score matching (PSM) was applied to ensure group comparability, followed by a comparison analysis regarding the primary endpoint of POAF and the secondary endpoints of all-cause mortality and stroke during a five-year follow-up. Results: A total of 933 patients were enrolled in the study eventually revealing a significant correlation between LAAPd and POAF (cor = 0.09, p < 0.01). A cut-off point of 38.5 mm was identified, resulting in groups with 366 patients each after PSM. Overall, patients with a dilated LA presented a significantly higher rate of POAF (22.3% vs. 30.4%, p = 0.02). In a five-year follow-up, a slightly higher rate of all-cause mortality (9.8% vs. 13.7%, HR 1.4 [0.92-2.29], p = 0.10) was observed, but there was no difference in the occurrence of strokes (3.6% vs. 3.3%, p = 0.87). Conclusions: An LAAPd of >38.5 mm was found to be an independent predictor of POAF after coronary artery bypass grafting and resulted in a non-significant tendency towards a worse outcome regarding all-cause mortality in a five-year follow-up.
RESUMO
BACKGROUND: Tricuspid valve transcatheter edge-to-edge repair (T-TEER) is the most widely used transcatheter therapy to treat patients with tricuspid regurgitation (TR). OBJECTIVES: The aim of this study was to develop a simple anatomical score to predict procedural outcomes of T-TEER. METHODS: All patients (n = 168) who underwent T-TEER between January 2017 and November 2022 at 2 centers were included in the derivation cohort. Additionally, 126 patients from 2 separate institutions served as a validation cohort. T-TEER was performed using 2 commercially available technologies. Core laboratory assessment of procedural transesophageal echocardiograms was used to determine septolateral and anteroposterior coaptation gap, leaflet morphology, septal leaflet length and retraction, chordal structure density, tethering height, en face TR jet morphology and TR jet location, image quality, and the presence of intracardiac leads. A scoring system was derived using univariable and multivariable logistic regression. Endpoints assessed were immediate postprocedural TR reduction ≥2 grades and TR grade moderate or less. RESULTS: The median age was 82 years (Q1-Q3: 78-84 years); 48% of patients were women; and patients presented with severe (55%), massive (36%), and torrential (8%) TR. Five variables (septolateral coaptation gap, chordal structure density, en face TR jet morphology, TR jet location, and image quality) were identified as best predicting procedural outcome and were incorporated in the GLIDE (Gap, Location, Image quality, density, en-face TR morphology) score (range 0-5). TR reduction ≥2 grades and TR grade moderate or less were observed in >90% of patients with GLIDE scores of 0 and 1 and in only 5.6% and 16.7% of those with GLIDE scores ≥4. The GLIDE score was then externally validated in a separate cohort (area under the curve: 0.77; 95% CI: 0.69-0.86). TR reduction significantly correlated with functional improvement assessed by NYHA functional class and 6-minute walk distance at 3 months. CONCLUSIONS: The GLIDE score is a simple, 5-component score that is readily obtained during patient imaging and can predict successful T-TEER.

BACKGROUND: Baseline right ventricular (RV) function derived from 3-dimensional analyses has been demonstrated to be predictive in patients undergoing transcatheter tricuspid valve repair (TTVR). The complex nature of these cumbersome analyses makes patient selection based on established imaging methods challenging. Artificial intelligence (AI)-driven computed tomography (CT) segmentation of the RV might serve as a fast and predictive tool for evaluating patients prior to TTVR. METHODS: Patients suffering from severe tricuspid regurgitation underwent full cycle cardiac CT. AI-driven analyses were compared to conventional CT analyses. Outcome measures were correlated with survival free of rehospitalization for heart-failure or death after TTVR as the primary endpoint. RESULTS: Automated AI-based image CT-analysis from 100 patients (mean age 77 ± 8 years, 63% female) showed excellent correlation for chamber quantification compared to conventional, core-lab evaluated CT analysis (R 0.963-0.966; p < 0.001). At 1 year (mean follow-up 229 ± 134 days) the primary endpoint occurred significantly more frequently in patients with reduced RV ejection fraction (EF) <50% (36.6% vs. 13.7%; HR 2.864, CI 1.212-6.763; p = 0.016). Furthermore, patients with dysfunctional RVs defined as end-diastolic RV volume > 210 ml and RV EF <50% demonstrated worse outcome than patients with functional RVs (43.7% vs. 12.2%; HR 3.753, CI 1.621-8.693; p = 0.002). CONCLUSIONS: Derived RVEF and dysfunctional RV were predictors for death and hospitalization after TTVR. AI-facilitated CT analysis serves as an inter- and intra-observer independent and time-effective tool which may thus aid in optimizing patient selection prior to TTVR in clinical routine and in trials.

BACKGROUND: A novel echocardiography-based definition of atrial functional tricuspid regurgitation (A-FTR) has shown superior outcomes in patients undergoing conservative treatment or tricuspid valve transcatheter edge-to-edge repair. Its prognostic significance for transcatheter tricuspid valve annuloplasty (TTVA) outcomes is unknown. OBJECTIVES: This study sought to investigate prognostic, clinical, and technical implications of A-FTR phenotype in patients undergoing TTVA. METHODS: This multicenter study investigated clinical and echocardiographic outcomes up to 1 year in 165 consecutive patients who underwent TTVA for A-FTR (characterized by the absence of tricuspid valve tenting, midventricular right ventricular [RV] dilatation, and impaired left ventricular ejection fraction) and nonatrial functional tricuspid regurgitation (NA-FTR). RESULTS: A total of 62 A-FTR and 103 NA-FTR patients were identified, with the latter exhibiting more pronounced RV remodeling. Compared to baseline, the tricuspid regurgitation (TR) grade at discharge was significantly reduced (P < 0.001 for both subtypes), and TR ≤II was achieved more frequently in A-FTR (85.2% vs 60.8%; P = 0.001). Baseline TR grade and A-FTR phenotype were independently associated with TR ≤II at discharge and 30 days. In multivariate analyses, A-FTR phenotype was a strong predictor (OR: 5.8; 95% CI: 2.1-16.1; P < 0.001) of TR ≤II at 30 days. At 1 year, functional class had significantly improved compared to baseline (both P < 0.001). One-year mortality was lower in A-FTR (6.5% vs 23.8%; P = 0.011) without significant differences in heart failure hospitalizations (13.3% vs 22.7%; P = 0.188). CONCLUSIONS: Direct TTVA effectively reduces TR in both A-FTR, which is a strong and independent predictor of achieving TR ≤II, and NA-FTR. Even though NA-FTR showed more RV remodeling at baseline, both phenotypes experienced similar symptomatic improvement, emphasizing the benefit of TTVA even in advanced disease stages. Additionally, phenotyping was of prognostic relevance in patients undergoing TTVA.

BACKGROUND: Permanent pacemaker implantation (PMI) is associated with increased morbidity after transcatheter aortic valve replacement (TAVR). Cardiac resynchronization-therapy (CRT) is recommended for patients if left ventricular ejection fraction (LVEF) is ≤ 40% and ventricular pacing is expected in favor to sole right ventricular (RV) pacing. Meanwhile, LVEF may recover after TAVR in patients with aortic valve disease and the benefit of CRT is unknown. OBJECTIVE: To analyze the impact of CRT implantation as compared to RV pacing after TAVR. METHODS AND RESULTS: Between 2012 and 2022, 4385 patients (53.1% female, mean age 81 ± 6 years) without prior PMI undergoing TAVR were retrospectively identified in our institutional registry. After stratification of patients in LVEF ≤ 40%, 41-49% and ≥ 50%, Kaplan-Meier analysis revealed significantly different survival rates in each subgroup at 5 years (37.0% vs. 43.5% vs. 55.1%; P ≤ 0.021). At multivariate regression, LVEF and new PMI after TAVR were not relevant for survival. A total of 105 patients with LVEF ≤ 40% received PMI after TAVR (86 patients with RV pacing and 19 with CRT). At 5 years, all-cause mortality was significantly lower in patients with CRT-device as compared to patients without CRT-device (Kaplan Meier estimate of 21.1% vs. 48.8%; HR 0.48, CI 0.204 - 1.128; log rank p = 0.045). In multivariate analysis CRT remained a significant factor for 5-year survival in these patients (HR 0.3, CI 0.095-0.951, p = 0.041). CONCLUSION: In patients undergoing TAVR, PMI did not influence 5-year survival. In patients with LVEF ≤ 40%, CRT-device implantation was associated with improved survival compared to non-CRT-device implantation.
RESUMO
AIMS: While invasively determined congestion holds mechanistic and prognostic significance in acute heart failure (HF), its role in patients with tricuspid regurgitation (TR)-related right- heart failure (HF) undergoing transcatheter tricuspid valve intervention (TTVI) is less well established. A comprehensive understanding of congestion patterns might aid in procedural planning, risk stratification, and the identification of patients who may benefit from adjunctive therapies before undergoing TTVI. The aim of this study was to investigate the role of congestion patterns in patients with severe TR and its implications for TTVI. METHODS AND RESULTS: Within a multicentre, international TTVI registry, 813 patients underwent right heart catheterization (RHC) prior to TTVI and were followed up to 24 months. The median age was 80 (interquartile range 76-83) years and 54% were women. Both mean right atrial pressure (RAP) and pulmonary capillary wedge pressure (PCWP) were associated with 2-year mortality on Cox regression analyses with Youden index-derived cut-offs of 17 mmHg and 19 mmHg, respectively (p < 0.01 for all). However, RAP emerged as an independent predictor of outcomes following multivariable adjustments. Pre-interventionally, 42% of patients were classified as euvolaemic (RAP <17 mmHg, PCWP <19 mmHg), 23% as having left-sided congestion (RAP <17 mmHg, PCWP ≥19 mmHg), 8% as right-sided congestion (RAP ≥17 mmHg, PCWP <19 mmHg), and 27% as bilateral congestion (RAP ≥17 mmHg, PCWP ≥19 mmHg). Patients with right-sided or bilateral congestion had the lowest procedural success rates and shortest survival times. Congestion patterns allowed for discerning specific patient's physiology and specifying prognostic implications of right ventricular to pulmonary artery coupling surrogates. CONCLUSION: In this large cohort of invasively characterized patients undergoing TTVI, congestion patterns involving right-sided congestion were associated with low procedural success and higher mortality rates after TTVI. Whether pre-interventional reduction of right-sided congestion can improve outcomes after TTVI should be established in dedicated studies.

Sleep-disordered breathing is common in patients with coronary artery disease undergoing coronary artery bypass grafting. Sleep-disordered breathing is associated with increased perioperative morbidity, arrhythmias (e.g. atrial fibrillation) and mortality. This study investigated the impact of sleep-disordered breathing on the postoperative course after coronary artery bypass grafting, including development of atrial fibrillation. This prospective single-centre cohort study included adults undergoing coronary artery bypass grafting. All were screened for sleep-disordered breathing (polygraphy) and atrial fibrillation (electrocardiogram) preoperatively; those with known sleep-disordered breathing or atrial fibrillation were excluded. Endpoints included new-onset atrial fibrillation, duration of mechanical ventilation, time in the intensive care unit, and postoperative infection. Regression analysis was performed to identify associations between sleep-disordered breathing and these outcomes. A total of 508 participants were included (80% male, median age 68 years). The prevalence of any (apnea-hypopnea index ≥ 5 per hr), moderate (apnea-hypopnea index = 15-30 per hr) and severe (apnea-hypopnea index > 30 per hr) sleep-disordered breathing was 52.9%, 9.3% and 10.2%, respectively. All-cause 30-day mortality was 0.98%. After adjustment for age and sex, severe sleep-disordered breathing was associated with longer respiratory ventilation support (crude odds ratio [95% confidence interval] 5.28 [2.18-12.77]; p < 0.001) and higher postoperative infection rates (crude odds ratio 3.32 [1.45-7.58]; p < 0.005), but not new-onset atrial fibrillation or mortality. New-onset atrial fibrillation was significantly associated with postoperative infection and prolonged hospital stay. The significant associations between sleep-disordered breathing and several adverse outcomes after coronary artery bypass grafting support the need for preoperative sleep-disordered breathing screening in individuals undergoing cardiac surgery.

BACKGROUND: Bleeding is the most common complication after percutaneous leaflet-based tricuspid valve repair and associated with acute kidney injury (AKI) and adverse outcome. TTVA with the Cardioband system is a technically more complex procedure; however, frequency and prognostic impact of postinterventional bleeding and renal complications have not been thoroughly examined. AIMS: This study was performed to determine the incidence and clinical impact of bleeding complications (MVARC criteria) and acute kidney injury (KDIGO criteria) following transcatheter tricuspid valve annuloplasty (TTVA). METHODS: In a bi-center retrospective analysis of patients undergoing TTVA between 2018 and 2022, we examined frequency, predictors, and clinical impact of bleeding and renal failure. RESULTS: In 145 consecutive patients, the incidence of any MVARC bleeding was 20.7% (n = 30), whereas major MVARC bleeding occurred in 6.9% (n = 10). The incidence of AKI was 18.6% (n = 27). Risk factors for bleeding events included low baseline hemoglobin and elevated baseline creatinine levels. Risk factors for AKI included diabetes mellitus, arterial hypertension, high body mass index, and elevated baseline creatinine levels. Neither procedure duration nor amount of contrast media was associated with AKI or bleeding. Both bleeding and AKI led to a longer hospital stay. At 3 months, 10.0% (n = 3) of patients with bleeding and 7.8% (n = 9) of patients without bleeding complications died (p = 0.70). Additionally, mortality rate was 7.4% (n = 2) in patients with AKI compared to 8.5% (n = 10) without AKI (p = 0.83). CONCLUSION: While about a fifth of patients undergoing TTVA suffered from postinterventional AKI or bleeding, none of these complications was associated with higher mortality at short-term follow-up. One important risk factor for both complications was chronic renal dysfunction, indicating a high-risk patient population. The most frequent bleeding localizations were the femoral access site, pericardial hemorrhage, and the esophagus, which need explicit attention in periprocedural management.

Both the MitraClip and PASCAL systems offer transcatheter edge-to-edge repair (TEER) solutions for mitral regurgitation. Evidence indicates a lower technical success rate for TEER in complex degenerative mitral regurgitation (DMR) cases. We conducted a retrospective analysis of patients who underwent transcatheter edge-to-edge therapy for primary mitral regurgitation with advanced anatomy, defined as mitral regurgitation effective regurgitant orifice area (MR-EROA) ≥0.40 cm2 or large flail gap (≥5 mm) or width (≥7 mm) or Barlow's disease, that completed follow-up after 1 year. Our criteria were met by 27 patients treated with PASCAL and 18 with MitraClip. All patients exhibited a significant, equivalent short-term reduction in MR-EROA, mitral regurgitation vena contracta diameter (MR-VCD), regurgitant volume, and clinical status. At 1 year follow-up, reductions in MR-VCD, regurgitant volume, and MR-EROA remained significant for both groups without significant differences between groups. MR-Grade ≤ 1+ was achieved in 18 (66.7%) and 10 (55.6%) patients, respectively. At follow-up, no difference in hospitalization for cardiac decompensation was observed. Overall death was similar in both groups. Our study suggests that both the PASCAL and MitraClip systems significantly reduce mitral regurgitation even in advanced degenerative diseases. Within our limited data, we found no evidence of inferior performance of the PASCAL system.
RESUMO
Cardiac resynchronisation therapy (CRT) is an established treatment for patients with symptomatic heart failure with reduced left ventricular ejection fraction (LVEF ≤ 35%; HFrEF) and conduction disturbances (QRS duration ≥ 130 ms). The presence of mechanical dyssynchrony (MD) on echocardiography has been hypothesised to be of predictive value in determining indication for CRT. This study investigated the impact of MD (apical rocking [AR] and septal flash [SF]) on long-term survival in CRT recipients. HFrEF patients (n = 425; mean age 63.0 ± 10.6 years, 72.3% male, 60.7% non-ischaemic aetiology) with a guideline-derived indication for CRT underwent device implantation. MD markers were determined at baseline and after a mean follow-up of 11.5 ± 8.0 months; long-term survival was also determined. AR and/or SF were present in 307 (72.2%) participants at baseline. During post-CRT follow-up, AR and/or SF disappeared in 256 (83.4%) patients. Overall mean survival was 95.9 ± 52.9 months, longer in women than in men (109.1 ± 52.4 vs. 90.9 ± 52.4 months; p < 0.001) and in younger (< 60 years) versus older patients (110.6 ± 53.7 vs. 88.6 ± 51.1 months; p < 0.001). Patients with versus without MD markers at baseline generally survived for longer (106.2 ± 52.0 vs. 68.9 ± 45.4 months; p < 0.001), and survival was best in patients with resolved versus persisting MD (111.6 ± 51.2 vs. 79.7 ± 47.6 months p < 0.001). Age and MD at baseline were strong predictors of long-term survival in HFrEF patients undergoing CRT on multivariate analysis. Novel echocardiography MD parameters in HFrEF CRT recipients predicted long-term mediated better outcome, and survival improved further when AR and/or SF disappear after CRT implantation.

AIMS: Transcatheter 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 RESULTS: Patients 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. 49â mm, P = 0.004), a better right ventricular function (fractional area change 45 vs. 41%, P = 0.001), a smaller right (28 vs. 34â cm2, P = 0.021) and left (52 vs. 67â 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 ± 5â mm, P = 0.19), and T-TEER significantly reduced TR in both groups (TR vena contracta width post-interventional 4 ± 3 vs. 5 ± 5â mm, P = 0.10). These findings remained stable after propensity score matching. Complications were similar between both groups. CONCLUSION: T-TEER confers equally safe and effective reduction of TR in patients with primary and secondary TR.
