RESUMO
AIM: The RESHAPE-HF2 trial is designed to assess the efficacy and safety of the MitraClip device system for the treatment of clinically important functional mitral regurgitation (FMR) in patients with heart failure (HF). This report describes the baseline characteristics of patients enrolled in the RESHAPE-HF2 trial compared to those enrolled in the COAPT and MITRA-FR trials. METHODS AND RESULTS: The RESHAPE-HF2 study is an investigator-initiated, prospective, randomized, multicentre trial including patients with symptomatic HF, a left ventricular ejection fraction (LVEF) between 20% and 50% with moderate-to-severe or severe FMR, for whom isolated mitral valve surgery was not recommended. Patients were randomized 1:1 to a strategy of delivering or withholding MitraClip. Of 506 patients randomized, the mean age of the patients was 70 ± 10 years, and 99 of them (20%) were women. The median EuroSCORE II was 5.3 (2.8-9.0) and median plasma N-terminal pro-B-type natriuretic peptide (NT-proBNP) was 2745 (1407-5385) pg/ml. Most patients were prescribed beta-blockers (96%), diuretics (96%), angiotensin-converting enzyme inhibitors/angiotensin receptor blockers/angiotensin receptor-neprilysin inhibitors (82%) and mineralocorticoid receptor antagonists (82%). The use of sodium-glucose cotransporter 2 inhibitors was rare (7%). Cardiac resynchronization therapy (CRT) devices had been previously implanted in 29% of patients. Mean LVEF, left ventricular end-diastolic volume and effective regurgitant orifice area (EROA) were 31 ± 8%, 211 ± 76 ml and 0.25 ± 0.08 cm2, respectively, whereas 44% of patients had mitral regurgitation severity of grade 4+. Compared to patients enrolled in COAPT and MITRA-FR, those enrolled in RESHAPE-HF2 were less likely to have mitral regurgitation grade 4+ and, on average, HAD lower EROA, and plasma NT-proBNP and higher estimated glomerular filtration rate, but otherwise had similar age, comorbidities, CRT therapy and LVEF. CONCLUSION: Patients enrolled in RESHAPE-HF2 represent a third distinct population where MitraClip was tested in, that is one mainly comprising of patients with moderate-to-severe FMR instead of only severe FMR, as enrolled in the COAPT and MITRA-FR trials. The results of RESHAPE-HF2 will provide crucial insights regarding broader application of the transcatheter edge-to-edge repair procedure in clinical practice.

AIMS: This study was performed to compare haemodynamic properties of a novel transcatheter heart valve (THV) with two established valve technologies for treatment of failing surgical aortic bioprosthetic valves (SAV). The ALLEGRA THV has been recently described with a proven safety and performance profile. METHODS AND RESULTS: The study was designed as a retrospective, single-centre study investigating 112 patients (77.7 ± 7.1 years, 53.8% female, STS score 6.8 ± 5.8% and logEuroSCORE I 27.4 ± 16.1%) with failing SAV. Patients were treated with the ALLEGRA THV (NVT, n = 24), the CoreValve/EvolutR (MTD, n = 64) or the Edwards Sapien/Sapien XT/Sapien 3 (EDW, n = 24). Adverse events, haemodynamic outcomes and patient safety were analysed according to VARC-3 definitions. Overall procedural success was high (94.6%), even though 58.9% of the treated SAV were classified as small (true inner diameter < 21 mm). After treatment, the mean pressure gradient was significantly reduced (baseline: 33.7 ± 16.5 mmHg, discharge: 18.0 ± 7.1 mmHg), with a corresponding increase in effective orifice area (EOA). The complication rates did not differ in between groups. There was a trend to lower mean transvalvular gradients after implantation of self-expanding THV with supra-annular valve function, despite a higher frequency of smaller SAVs in the NVT and MTD group. Additionally, comparison between NVT and MTD revealed statistically lower transvalvular gradients (NVT 14.9 ± 5.0 mmHg, MTD 18.7 ± 7.5 mmHg, p = 0.0295) in a subgroup analysis. CONCLUSIONS: Valve-in-valve (ViV) treatment of failing SAV with supra-annular design like the ALLEGRA THV resulted in favourable haemodynamic outcomes with similar low clinical event rates and may therefore be an interesting alternative for VIV TAVI.

OBJECTIVES: The authors sought to evaluate the incidence, predictors, and outcomes of new permanent pacemaker implantation (PPI) after transcatheter aortic valve replacement (TAVR) with contemporary self-expanding valves (SEV). BACKGROUND: Need for PPI is frequent post-TAVR, but conflicting data exist on new-generation SEV and on the prognostic impact of PPI. METHODS: This study included 3,211 patients enrolled in the multicenter NEOPRO (A Multicenter Comparison of Acurate NEO Versus Evolut PRO Transcatheter Heart Valves) and NEOPRO-2 (A Multicenter Comparison of ACURATE NEO2 Versus Evolut PRO/PRO+ Transcatheter Heart Valves 2) registries (January 2012 to December 2021) who underwent transfemoral TAVR with SEV. Implanted transcatheter heart valves (THV) were Acurate neo (n = 1,090), Acurate neo2 (n = 665), Evolut PRO (n = 1,312), and Evolut PRO+ (n = 144). Incidence and predictors of new PPI and 1-year outcomes were evaluated. RESULTS: New PPI was needed in 362 patients (11.3%) within 30 days after TAVR (8.8%, 7.7%, 15.2%, and 10.4%, respectively, after Acurate neo, Acurate neo2, Evolut PRO, and Evolut PRO+). Independent predictors of new PPI were Society of Thoracic Surgeons Predicted Risk of Mortality score, baseline right bundle branch block and depth of THV implantation, both in patients treated with Acurate neo/neo2 and in those treated with Evolut PRO/PRO+. Predischarge reduction in ejection fraction (EF) was more frequent in patients requiring PPI (P = 0.014). New PPI was associated with higher 1-year mortality (16.9% vs 10.8%; adjusted HR: 1.66; 95% CI: 1.13-2.43; P = 0.010), particularly in patients with baseline EF <40% (P for interaction = 0.049). CONCLUSIONS: New PPI was frequently needed after TAVR with SEV (11.3%) and was associated with higher 1-year mortality, particularly in patients with EF <40%. Baseline right bundle branch block and depth of THV implantation independently predicted the need of PPI.

BACKGROUND: Acute kidney injury (AKI) after transcatheter aortic valve implantation (TAVI) is a serious complication which is associated with increased mortality. The RenalGuard system was developed to reduce the risk of AKI after contrast media exposition by furosemide-induced diuresis with matched isotonic intravenous hydration. The aim of this study was to examine the effect of the RenalGuard system on the occurrence of AKI after TAVI in patients with chronic kidney disease. METHODS: The present study is a single-center randomized trial including patients with severe aortic valve stenosis undergoing TAVI. Overall, a total of 100 patients treated by TAVI between January 2017 and August 2018 were randomly assigned to a periprocedural treatment with the RenalGuard system or standard treatment by pre- and postprocedural intravenous hydration. Primary endpoint was the occurrence of AKI after TAVI, and secondary endpoints were assessed according to valve academic research consortium 2 criteria. RESULTS: Overall, the prevalence of AKI was 18.4% (n = 18). The majority of these patients developed mild AKI according to stage 1. Comparing RenalGuard to standard therapy, no significant differences were observed in the occurrence of AKI (RenalGuard: 21.3%; control group: 15.7%; p = 0.651). In addition, there were no differences between the groups with regard to 30-day and 12-month mortality and procedure-associated complication rates. CONCLUSION: In this randomized trial, we did not detect a reduction in AKI after TAVI by using the RenalGuard system. A substantial number of patients with chronic kidney disease developed AKI after TAVI, whereas the majority presented with mild AKI according to stage 1 (ClinicalTrials.gov number NCT04537325).
RESUMO
BACKGROUND: Mitral valve transcatheter edge-to-edge repair (M-TEER) is an effective option for treatment of mitral regurgitation (MR). We previously reported favorable 2-year outcomes for the PASCAL transcatheter valve repair system. OBJECTIVES: We report 3-year outcomes from the multinational, prospective, single-arm CLASP study with analysis by functional MR (FMR) and degenerative MR (DMR). METHODS: Patients with core-lab determined MR ≥ 3+ were deemed candidates for M-TEER by the local heart team. Major adverse events were assessed by an independent clinical events committee to 1 year and by sites thereafter. Echocardiographic outcomes were evaluated by the core laboratory to 3 years. RESULTS: The study enrolled 124 patients, 69% FMR; 31% DMR (60% NYHA class III-IVa, 100% MR ≥ 3+). The 3-year Kaplan-Meier estimate for survival was 75% (66% FMR; 92% DMR) and freedom from heart failure hospitalization (HFH) was 73% (64% FMR; 91% DMR), with 85% reduction in annualized HFH rate (81% FMR; 96% DMR) (p < 0.001). MR ≤ 2+ was achieved and maintained in 93% of patients (93% FMR; 94% DMR) and MR ≤ 1+ in 70% of patients (71% FMR; 67% DMR) (p < 0.001). The mean left ventricular end-diastolic volume (181 mL at baseline) decreased progressively by 28 mL [p < 0.001]. NYHA class I/II was achieved in 89% of patients (p < 0.001). CONCLUSIONS: The 3-year results from the CLASP study demonstrated favorable and durable outcomes with the PASCAL transcatheter valve repair system in patients with clinically significant MR. These results add to the growing body of evidence establishing the PASCAL system as a valuable therapy for patients with significant symptomatic MR.

BACKGROUND: Midterm data comparing clinical outcomes after successful implantation of self-expanding and balloon-expandable transcatheter heart valves (THV) are limited. We aimed to compare 2-year outcomes after successful transcatheter aortic valve implantation (TAVI) with the Edwards balloon-expandable or the Medtronic self-expanding THV. METHODS: Two-year outcomes were analyzed according to the implanted THV in the GALILEO trial. Major adverse cardiac and cerebrovascular events (MACCE) was a composite of all-cause death or thromboembolic events including stroke, myocardial infarction, symptomatic valve thrombosis, systemic embolism, deep-vein thrombosis, or pulmonary embolism. RESULTS: Among 1644 patients recruited in 136 centers across 16 countries between 2015 and 2018, 499 received a self-expanding and 757 patients received a balloon-expandable THV. Patients treated with a self-expanding THV were more likely to be female, and had higher surgical risk, lower hemoglobin levels, and more frequent valve-in-valve procedures than those with a balloon-expandable THV. After multivariable adjustment, there were no significant differences in major clinical outcomes between self-expanding versus balloon-expandable THV: MACCE (17.0% vs. 13.4%, adjusted-hazard ratios [HR] 1.18, 95% confidence intervals [CI]: 0.82-1.69); all-cause death (11.4% vs. 9.3%, adjusted-HR 1.26; 95% CI: 0.78-2.05); cardiovascular death (8.5% vs. 4.0%, adjusted-HR 1.53; 95% CI: 0.82-2.86), any stroke (5.1% vs. 3.7%, adjusted-HR 0.86; 95% CI: 0.43-1.73); major or life-threatening bleeding (5.9% vs. 6.8%, adjusted-HR 0.93; 95% CI: 0.53-1.63). CLINICAL TRIAL REGISTRATION: https://www. CLINICALTRIALS: gov. NCT02556203. CONCLUSIONS: Two-year follow-up data from the GALILEO trial indicate that successful TAVI either with self-expanding or balloon-expandable THVs according to physician discretion did not show difference in rates of MACCE.

BACKGROUND: Transcatheter aortic valve replacement (TAVR) with the ACURATE neo device has been associated with a non-negligible incidence of paravalvular aortic regurgitation (AR). The new-generation ACURATE neo2 has been designed to mitigate this limitation. AIMS: The aim of the study was to compare TAVR with the ACURATE neo and neo2 devices. METHODS: The NEOPRO and NEOPRO-2 registries retrospectively included patients undergoing transfemoral TAVR with self-expanding valves at 24 and 20 centres, respectively. Patients receiving the ACURATE neo and neo2 devices (from January 2012 to December 2021) were included in this study. Predischarge and 30-day VARC-3 defined outcomes were evaluated. The primary endpoint was predischarge moderate or severe paravalvular AR. Subgroup analyses per degree of aortic valve calcification were performed. RESULTS: A total of 2,026 patients (neo: 1,263, neo2: 763) were included. Predischarge moderate or severe paravalvular AR was less frequent for the neo2 group (2% vs 5%; p<0.001), resulting in higher VARC-3 intended valve performance (96% vs 90%; p<0.001). Furthermore, more patients receiving the neo2 had none/trace paravalvular AR (59% vs 38%; p<0.001). The reduction in paravalvular AR with neo2 was mainly observed with heavy aortic valve calcification. New pacemaker implantation and VARC-3 technical and device success rates were similar between the 2 groups; there were more frequent vascular and bleeding complications for the neo device. Similar 1-year survival was detected after TAVR (neo2: 90% vs neo: 87%; p=0.14). CONCLUSIONS: TAVR with the ACURATE neo2 device was associated with a lower prevalence of moderate or severe paravalvular AR and more patients with none/trace paravalvular AR. This difference was particularly evident with heavy aortic valve calcification.

BACKGROUND: The agreement between single-projection Murray-based quantitative flow ratio (mQFR) and conventional three-dimensional quantitative flow ratio (3D-QFR) has not been reported hitherto. METHODS: Patients from a multinational database were randomly selected for the study of agreement, according to sample size calculation. Both conventional 3D-QFR and mQFR were analyzed for all available arteries at a central corelab by independent analysts, blinded to each other's results. RESULTS: Ninety-eight coronary arteries from 35 patients were finally analyzed. Median 3D-QFR was 0.82 (interquartile range 0.78-0.87). The intraclass correlation coefficient for the absolute agreement between 3D-QFR and mQFR was 0.996 (95% confidence interval [CI]: 0.993-0.997); Lin's coefficient 0.996 (95% CI: 0.993-0.997), without constant or proportional bias (intercept = 0 and slope = 1 in orthogonal regression). As dichotomous variable, there was absolute agreement between mQFR and 3D-QFR, resulting in no single false positive or negative. Kappa index was 1 and the diagnostic accuracy 100%. CONCLUSIONS: mQFR using a single angiographic projection showed almost perfect agreement with standard 3D-QFR. These results encourage the interchangeable use of mQFR and 3D-QFR, which can be interesting to improve QFR feasibility in retrospective studies, wherein appropriate double angiographic projections might be challenging to obtain.

Critically ill COVID-19 patients are at high risk for venous thromboembolism (VTE), namely deep vein thrombosis (DVT) and/or pulmonary embolism (PE), and death. The optimal anticoagulation strategy in critically ill patients with COVID-19 remains unknown. This study investigated the ante mortem incidence as well as postmortem prevalence of VTE, the factors predictive of VTE, and the impact of changed anticoagulation practice on patient survival. We conducted a consecutive retrospective analysis of postmortem COVID-19 (n = 64) and non-COVID-19 (n = 67) patients, as well as ante mortem COVID-19 (n = 170) patients admitted to the University Medical Center Hamburg-Eppendorf (Hamburg, Germany). Baseline patient characteristics, parameters related to the intensive care unit (ICU) stay, and the clinical and autoptic presence of VTE were evaluated and statistically compared between groups. The occurrence of VTE in critically ill COVID-19 patients is confirmed in both ante mortem (17%) and postmortem (38%) cohorts. Accordingly, comparing the postmortem prevalence of VTE between age- and sex-matched COVID-19 (43%) and non-COVID-19 (0%) cohorts, we found the statistically significant increased prevalence of VTE in critically ill COVID-19 cohorts (p = 0.001). A change in anticoagulation practice was associated with the statistically significant prolongation of survival time (HR: 2.55, [95% CI 1.41-4.61], p = 0.01) and a reduction in VTE occurrence (54% vs. 25%; p = 0.02). In summary, in the autopsy as well as clinical cohort of critically ill patients with COVID-19, we found that VTE was a frequent finding. A change in anticoagulation practice was associated with a statistically significantly prolonged survival time.

We present a patient with acute heart failure and new onset atrial fibrillation secondary to giant cell myocarditis with lone atrial involvement. The diagnosis was managed with cardiac magnetic resonance and confirmed by interventionally guided biopsy. In the future, diagnosis could be managed noninvasively for this rare entity as the gold standard. (Level of Difficulty: Advanced.).
RESUMO
BACKGROUND: Transcatheter aortic valve replacement (TAVR) is safe and feasible in patients with bicuspid aortic valve (BAV), but whether annular size may influence TAVR results in BAV patients remains unclear. We aimed at evaluating the impact of aortic annular size on procedural and clinical outcomes of BAV patients undergoing TAVR, as well as potential interactions between annular dimension and trans-catheter heart valve (THV) type (balloon-expandable (BEV) vs. self-expanding (SEV). METHODS: BEAT is a multicenter registry of consecutive BAV stenosis undergoing TAVR. For this sub-study patients were classified according to annular dimension in small-annulus (area < 400 mm2 or perimeter <72 mm), medium-annulus (area ≥ 400 and < 575 mm2, perimeter ≥72 mm and< 85 mm), large-annulus (area ≥ 575 mm2 or perimeter ≥85 mm). Primary endpoint was Valve Academic Research Consortium-2 (VARC-2) device success. RESULTS: 45(15.5%) patients had small, 132(45.3%) medium, and 114(39.2%) large annuli. Compared with other groups, patients with large annuli were more frequently male, younger, with higher body mass index, larger aortic valve area, higher rate of moderate-severe calcification, lower mean trans-aortic valve gradient and lower left ventricular ejection fraction. In large-annuli SEVs were associated with a lower VARC-2 device success (75.9% vs. 90.6%, p = 0.049) driven by a higher rate of paravalvular valvular leak (PVL) compared to BEVs (20.7% vs. 1.2%, p < 0.001). However, no differences in clinical outcomes were observed according to annular size nor THV type. CONCLUSIONS: TAVR in BAV patients is feasible irrespective of annular size. However in patients with large aortic annulus SEVs were associated with a significantly higher rate of PVLs compared to BEVs.

BACKGROUND: Transcatheter aortic valve implantation (TAVI) has become standard treatment for elderly patients with symptomatic severe aortic valve stenosis. The ACURATE neo AS study evaluates 30-day and 1-year clinical and hemodynamic outcomes in patients treated with the ACURATE neo2 valve. METHODS: The primary endpoint of this single-arm multicenter study is 30-day all-cause mortality. Other key endpoints include device performance, echocardiographic measures assessed by an independent core laboratory, and VARC-2 clinical efficacy and safety endpoints through 12 months. RESULTS: The study enrolled 120 patients (mean age 82.1 ± 4.0 years; 67.5% female, mean baseline STS score 4.8 ± 3.8%). The VARC-2 composite safety endpoint at 30 days occurred in 13.3% of patients. All-cause mortality was 3.3% at 30 days and 11.9% at 1 year. The 30-day stroke rate was 2.5% (disabling stroke 1.7%); there were no new strokes between 30 days and 12 months. The rate of permanent pacemaker implantation was 15.0% (18/120) at 30 days and 17.8% (21/120) at 1 year. No patients required re-intervention for valve-related dysfunction and there were no cases of valve thrombosis or endocarditis. Patients demonstrated significant improvement in mean aortic valve gradient (baseline 38.9 ± 13.1 mmHg, 1 year 7.8 ± 3.5 mmHg; P < 0.001 in a paired analysis). In the overall population, paravalvular leak was evaluated at 1 year as none/trace in 60.5%, mild in 37.0%, and moderate in 2.5%; no patients had severe PVL. CONCLUSIONS: One-year outcomes from the ACURATE neo AS study support the safety and performance of TAVI with the ACURATE neo2 valve.

BACKGROUND: Severe tricuspid regurgitation (TR) has limited treatment options and is associated with high morbidity and mortality. AIMS: We evaluated the safety and effectiveness of the Cardioband tricuspid valve reconstruction system from the ongoing European single-arm, multicentre, prospective TriBAND post-market clinical follow-up study. METHODS: Eligible patients had chronic symptomatic functional TR despite diuretic therapy and were deemed candidates for transcatheter tricuspid repair by the local Heart Team. RESULTS: Sixty-one patients had ≥severe functional TR. At baseline, 85% of patients were in NYHA Class III-IV, 94% had ≥severe TR (core laboratory-assessed) with 6.8% EuroSCORE II and 53% LVEF. Device success was 96.7%. At discharge, 59% (p<0.001) of patients achieved ≤moderate TR and 78% had at least one grade TR reduction. At 30 days, all-cause mortality and composite MAE rates were 1.6% and 19.7%, respectively; septolateral annular diameter was reduced by 20%, where 69% of patients achieved ≤moderate TR and 85% of patients had at least one grade TR reduction (all p<0.001). Mid-RVEDD, RA volume, and IVC diameter decreased by 10% (p=0.005), 21% (p<0.001), and 11% (p=0.022), respectively; 74% were in NYHA Class I-II (p<0.001) with improvements in overall KCCQ score by 17 points (p<0.001). CONCLUSIONS: In the TriBAND study, the Cardioband tricuspid system demonstrated favourable outcomes at discharge and 30 days in a challenging patient population with symptomatic ≥severe functional TR. Results showed significant reductions in annular diameter and TR severity, accompanied by early evidence of right heart remodelling and improvements in functional status and quality of life.

OBJECTIVES: This study reports 2-year outcomes from the multicenter, prospective, single-arm CLASP study with functional mitral regurgitation (FMR) and degenerative MR (DMR) analysis. BACKGROUND: Transcatheter repair is a favorable option to treat MR. Long-term prognostic impact of the PASCAL transcatheter valve repair system in patients with clinically significant MR remains to be established. METHODS: Patients had clinically significant MR ≥3+ as evaluated by the echocardiographic core laboratory and were deemed candidates for transcatheter repair by the heart team. Assessments were performed by clinical events committee to 1 year (site-reported thereafter) and core laboratory to 2 years. RESULTS: A total of 124 patients (69% FMR, 31% DMR) were enrolled with a mean age of 75 years, 56% were male, 60% were New York Heart Association functional class III to IVa, and 100% had MR ≥3+. At 2 years, Kaplan-Meier estimates showed 80% survival (72% FMR, 94% DMR) and 84% freedom from heart failure (HF) hospitalization (78% FMR, 97% DMR), with 85% reduction in annualized HF hospitalization rate (81% FMR, 98% DMR). MR ≤1+ was achieved in 78% of patients (84% FMR, 71% DMR) and MR ≤2+ was achieved in 97% (95% FMR, 100% DMR) (all p < 0.001). Left ventricular end-diastolic volume decreased by 33 ml (p < 0.001); 93% of patients were in New York Heart Association functional class I to II (p < 0.001). CONCLUSIONS: The PASCAL repair system demonstrated sustained favorable outcomes at 2 years in FMR and DMR patients. Results showed high survival and freedom from HF rehospitalization rates with a significantly reduced annualized HF hospitalization rate. Durable MR reduction was achieved with evidence of left ventricular reverse remodeling and significant improvement in functional status. The CLASP IID/IIF randomized pivotal trial is ongoing.

BACKGROUND: Tricuspid regurgitation (TR) has a poor prognosis and limited treatment options and is frequently accompanied by right ventricular (RV) dysfunction. Transcatheter tricuspid valve interventions (TTVI) to reduce TR have been shown to be safe and feasible with encouraging early results. Patient selection for TTVI remains challenging, with the role of right ventricular (RV) function being unknown. AIMS: The aims of this study were 1) to investigate survival in a TTVI-treated patient population and a conservatively treated TR population, and 2) to evaluate the outcome of TTVI as compared to conservative treatment stratified according to the degree of RV function. METHODS: We studied 684 patients from the multicentre TriValve cohort (TTVI cohort) and compared them to 914 conservatively treated patients from two tertiary care centres. Propensity matching identified 213 pairs of patients with severe TR. As we observed a non-linear relationship of RV function and TTVI outcome, we stratified patients according to tricuspid annular plane systolic excursion (TAPSE) to preserved (TAPSE >17 mm), mid-range (TAPSE 13-17 mm) and reduced (TAPSE <13 mm) RV function. The primary outcome was one-year all-cause mortality. RESULTS: TTVI was associated with a survival benefit in patients with severe TR when compared to matched controls (one-year mortality rate: 13.1% vs 25.8%; p=0.031). Of the three RV subgroups, only in patients with mid-range RV function was TTVI associated with an improved survival (p log-rank 0.004). In these patients, procedural success was associated with a reduced hazard ratio for all-cause mortality (HR 0.22; 95% CI: 0.09, 0.57). CONCLUSIONS: TTVI is associated with reduced mortality compared to conservative therapy and might exert its highest treatment effect in patients with mid-range reduced RV function.

BACKGROUND: Scarce data exist on patients with right ventricular dysfunction (RVD) or pulmonary hypertension (PH) undergoing transcatheter tricuspid valve intervention. This study aimed to determine the early and midterm outcomes and the factors associated with mortality in this group of patients. METHODS: This subanalysis of the multicenter TriValve (Transcatheter Tricuspid Valve Therapies) registry included 300 patients with severe tricuspid regurgitation with RVD (n=244), PH (n=127), or both (n=71) undergoing transcatheter tricuspid valve intervention. RVD was defined as a tricuspid annular plane systolic excursion <17 mm, and PH as an estimated pulmonary artery systolic pressure ≥50 mm Hg. RESULTS: Mean age of the patients was 77±9 years (54% women). Procedural success was 80.7%, and 9 patients (3%) died during the hospitalization. At a median follow-up of 6 (interquartile range, 2-12) months, 54 patients (18%) died, and the independent associated factors were higher gamma-glutamyl transferase values at baseline (hazard ratio, 1.02 for each increase of 10 u/L [95% CI, 1.002-1.04]), poorer renal function defined as an estimated glomerular filtration rate <45 mL/min (hazard ratio, 2.3 [95% CI, 1.22-4.33]), and the lack of procedural success (hazard ratio, 2.11 [95% CI, 1.17-3.81]). The grade of RVD and the amount of PH at baseline were not found to be predictors of mortality. Most patients alive at follow-up improved their functional class (New York Heart Association I-II in 66% versus 7% at baseline, P<0.001). CONCLUSIONS: In patients with severe tricuspid regurgitation and RVD/PH, transcatheter tricuspid valve intervention was associated with high procedural success and a relatively low in-hospital mortality, along with significant improvements in functional status. However, about 1 out of 5 patients died after a median follow-up of 6 months, with hepatic congestion, renal dysfunction, and the lack of procedural success determining an increased risk. These results may improve the clinical evaluation of transcatheter tricuspid valve intervention candidates and would suggest a closer follow-up in those at increased risk.

BACKGROUND: Scarce data exist on patients with previous left valve surgery (PLVS) undergoing transcatheter tricuspid valve intervention (TTVI). This study sought to investigate the procedural and early outcomes in patients with PLVS undergoing TTVI. METHODS: This was a subanalysis of the multicenter TriValve registry including 462 patients, 82 (18%) with PLVS. Data were analyzed according to the presence of PLVS in the overall cohort and in a propensity score-matched population including 51 and 115 patients with and without PLVS, respectively. RESULTS: Patients with PLVS were younger (72 ± 10 vs 78 ± 9 years; p < 0.01) and more frequently female (67.1% vs 53.2%; P = 0.02). Similar rates of procedural success (PLVS 80.5%; no-PLVS 82.1%; P = 0.73), and 30-day mortality (PLVS 2.4%, no-PLVS 3.4%; P = 0.99) were observed. After matching, there were no significant differences in both all-cause rehospitalisation (PLVS 21.1%, no-PLVS 26.5%; P = 0.60) and all-cause mortality (PLVS 9.8%, no-PLVS 6.7%; P = 0.58). At last follow-up (median 6 [interquartile range 1-12] months after the procedure), most patients (81.8%) in the PLVS group were in NYHA functional class I-II (P = 0.12 vs no-PLVS group), and TR grade was ≤ 2 in 82.6% of patients (P = 0.096 vs no-PVLS group). A poorer right ventricular function and previous heart failure hospitalization determined increased risks of procedural failure and poorer outcomes at follow-up, respectively. CONCLUSIONS: In patients with PLVS, TTVI was associated with high rates of procedural success and low early mortality. However, about one-third of patients required rehospitalisation or died at midterm follow-up. These results would support TTVI as a reasonable alternative to redo surgery in patients with PLVS and suggest the importance of earlier treatment to improve clinical outcomes.
