ABSTRACT
BACKGROUND AND AIMS: Mitral valve surgery and, more recently, mitral transcatheter edge-to-edge repair (TEER) are the two treatments of severe mitral regurgitation in eligible patients. Clinical comparison of both therapies remains limited by the number of patients analysed. The objective of this study was to analyse the outcomes of mitral TEER vs. isolated mitral valve surgery at a nationwide level in France. METHODS: Based on the French administrative hospital discharge database, the study collected information for all consecutive patients treated for mitral regurgitation with isolated TEER or isolated mitral valve surgery between 2012 and 2022. Propensity score matching was used for the analysis of outcomes. RESULTS: A total of 57 030 patients were found in the database. After matching on baseline characteristics, 2160 patients were analysed in each arm. At 3-year follow-up, TEER was associated with significantly lower incidence of cardiovascular death (hazard ratio 0.685, 95% confidence interval 0.563-0.832; P = .0001), pacemaker implantation, and stroke. Non-cardiovascular death (hazard ratio 1.562, 95% confidence interval 1.238-1.971; P = .0002), recurrent pulmonary oedema, and cardiac arrest were more frequent after TEER. No significant differences between the two groups were observed regarding all-cause death (hazard ratio 0.967, 95% confidence interval 0.835-1.118; P = .65), endocarditis, major bleeding, atrial fibrillation, and myocardial infarction. CONCLUSIONS: Our results suggest that TEER for severe mitral regurgitation was associated with lower cardiovascular mortality than mitral surgery at long-term follow-up. Pacemaker implantation and stroke were less frequently observed after TEER.

BACKGROUND AND AIMS: This trial sought to assess the safety and efficacy of ShortCut, the first dedicated leaflet modification device, prior to transcatheter aortic valve implantation (TAVI) in patients at risk for coronary artery obstruction. METHODS: This pivotal prospective study enrolled patients with failed bioprosthetic aortic valves scheduled to undergo TAVI and were at risk for coronary artery obstruction. The primary safety endpoint was procedure-related mortality or stroke at discharge or 7 days, and the primary efficacy endpoint was per-patient leaflet splitting success. Independent angiographic, echocardiographic, and computed tomography core laboratories assessed all images. Safety events were adjudicated by a clinical events committee and data safety monitoring board. RESULTS: Sixty eligible patients were treated (77.0 ± 9.6 years, 70% female, 96.7% failed surgical bioprosthetic valves, 63.3% single splitting and 36.7% dual splitting) at 22 clinical sites. Successful leaflet splitting was achieved in all (100%; 95% confidence interval [CI] 94-100.0%, p<0.001) patients. Procedure time, including imaging confirmation of leaflet splitting, was 30.6 ± 17.9 min. Freedom from the primary safety endpoint was achieved in 59 (98.3%; 95% CI [91.1-100%]) patients, with no mortality and one (1.7%) disabling stroke. At 30 days, freedom from coronary obstruction was 95% (95% CI 86.1-99.0%). Within 90 days, freedom from mortality was 95% (95% CI 86.1-99.0%]), without any cardiovascular deaths. CONCLUSIONS: Modification of failed bioprosthetic aortic valve leaflets using ShortCut was safe, achieved successful leaflet splitting in all patients, and was associated with favorable clinical outcomes in patients at risk for coronary obstruction undergoing TAVI.
ABSTRACT
INTRODUCTION: Bicuspid aortic valve (BAV) stenosis is a complex anatomical scenario for transcatheter aortic valve implantation (TAVI). Favorable short-term clinical outcomes have been reported with TAVI in this setting, but long-term data are scarce. METHODS: We retrospectively included, in a single-center registry, patients with BAV stenosis who underwent TAVI before 2020. We compared patients treated with self-expanding valves (SEV) versus balloon-expandable valves (BEV). The primary endpoint was a composite of all-cause mortality, stroke and need for aortic valve (AV) reintervention at 3 years. Secondary endpoints included each component of the primary endpoint, cardiovascular mortality, permanent pacemaker implantation (PPI) rate, mean gradient and ≥moderate paravalvular leak (PVL) rate. RESULTS: A total of 150 consecutive patients (SEV = 83, BEV = 67) were included. No significant differences were reported between SEV and BEV groups for the primary composite endpoint (SEV 35.9% vs. BEV 32%, p = 0.66), neither for clinical secondary endpoints (all-cause mortality SEV 28.1% vs. BEV 28%, p = 0.988; cardiovascular mortality SEV 14.1% vs. BEV 20%, p = 0.399; stroke SEV 12.5% vs. BEV 6%, p = 0.342; need for AV reintervention SEV 0% vs. BEV 0%; PPI SEV 28.1% vs. BEV 24%, p = 0.620). A lower mean gradient persisted up to 3 years in the SEV group (SEV 8.8 ± 3.8 mmHg vs. BEV 10.7 ± 3.2 mmHg, p = 0.063), while no significant difference was found in the rate of ≥ moderate PVL (SEV 3/30 vs. BEV 0/25, p = 0.242). CONCLUSIONS: In this single center registry, we observed favorable 3-year clinical outcomes in nonselected BAV patients treated with different generation devices, without significant differences between patients receiving SEV or BEV.

BACKGROUND AND AIMS: For patients with symptomatic, severe tricuspid regurgitation (TR), early results of transcatheter tricuspid valve (TV) intervention studies have shown significant improvements in functional status and quality of life associated with right-heart reverse remodelling. Longer-term follow-up is needed to confirm sustained improvements in these outcomes. METHODS: The prospective, single-arm, multicentre TRISCEND study enrolled 176 patients to evaluate the safety and performance of transcatheter TV replacement in patients with ≥moderate, symptomatic TR despite medical therapy. Major adverse events, reduction in TR grade and haemodynamic outcomes by echocardiography, and clinical, functional, and quality-of-life parameters are reported to one year. RESULTS: Enrolled patients were 71.0% female, mean age 78.7 years, 88.0% ≥ severe TR, and 75.4% New York Heart Association classes III-IV. Tricuspid regurgitation was reduced to ≤mild in 97.6% (P < .001), with increases in stroke volume (10.5 ± 16.8â mL, P < .001) and cardiac output (0.6 ± 1.2â L/min, P < .001). New York Heart Association class I or II was achieved in 93.3% (P < .001), Kansas City Cardiomyopathy Questionnaire score increased by 25.7 points (P < .001), and six-minute walk distance increased by 56.2â m (P < .001). All-cause mortality was 9.1%, and 10.2% of patients were hospitalized for heart failure. CONCLUSIONS: In an elderly, highly comorbid population with ≥moderate TR, patients receiving transfemoral EVOQUE transcatheter TV replacement had sustained TR reduction, significant increases in stroke volume and cardiac output, and high survival and low hospitalization rates with improved clinical, functional, and quality-of-life outcomes to one year.

BACKGROUND: Left ventricular (LV) volume reshaping reduces myocardial wall stress and may induce reverse remodeling in patients with heart failure with reduced ejection fraction. The AccuCinch Transcatheter Left Ventricular Restoration system consists of a series of anchors connected by a cable implanted along the LV base that is cinched to the basal free wall radius. We evaluated the echocardiographic and clinical outcomes following transcatheter left ventricular restoration. METHODS AND RESULTS: We analyzed 51 heart failure patients with a left ventricular ejection fraction between 20% and 40%, with no more than 2+ mitral regurgitation treated with optimal medical therapy, who subsequently underwent transcatheter left ventricular restoration. Serial echocardiograms, Kansas City Cardiomyopathy Questionnaire scores, and 6-minute walk test distances were measured at baseline through 12 months. Primary analysis end point was change in end-diastolic volume at 12 months compared with baseline. Patients (nâ¯=â¯51) were predominantly male (86%) with a mean age of 56.3 ± 13.1 years. Fluoroscopy showed LV free wall radius decreased by a median of 9.2 mm amounting to a 29.6% decrease in the free wall arc length. At 12 months, the LV end-diastolic volume decreased by 33.6 ± 34.8 mL (P < .01), with comparable decreases in the LV end-systolic volume. These decreases were associated with significant improvements in the overall Kansas City Cardiomyopathy Questionnaire score (16.4 ± 18.7 points; P < .01) and 6-minute hall walk test distance (45.9 ± 83.9 m; P < .01). There were no periprocedural deaths; through the 1-year follow-up, 1 patient died (day 280) and 1 patient received a left ventricular assist device (day 13). CONCLUSIONS: In patients with heart failure with reduced ejection fraction without significant mitral regurgitation receiving optimal medical therapy, the AccuCinch System resulted in decreases of LV volume, as well as improved quality of life and exercise endurance. A randomized trial is ongoing (NCT04331769).

BACKGROUND: Transcatheter mitral valve implantation (TMVI) is a novel therapeutic option for treating symptomatic mitral valve disease. Evaluating patient anatomical suitability is a critical step in the TMVI screening process, but currently requires specialized software and computerized device models. AIMS: This analysis sought to assess the effectiveness of simple and standardized multislice computed tomography (MSCT) anatomic measurements for their ability to discriminate between patients who passed anatomical screening for Tendyne™ TMVI. METHODS: Subjects screened for the Tendyne Expanded Clinical Study from January 2016 through September 2019 were included. Core laboratory screening measurements included mitral annular (MA) dimensions at end-systole and end-diastole, simulated device implantation, and neo-left ventricular outflow tract (LVOT) area. Additionally, nine standard measurements of patient anatomy were assessed for their predictive value of patients passing the anatomic screening process. RESULTS: Out of 496 subjects screened for eligibility, 257 subjects met clinical eligibility criteria with MA dimensions within the manufacturer's suggested range: 153 (59.5%) underwent TMVI while 104 (40.5%) were excluded from the study for other anatomic reasons (76% due to risk of LVOT obstruction). CT-derived left ventricular end-systole diameter (LVESD) had the highest discriminatory power for predicting TMVI anatomical suitability (area under the curve of 0.908, p < 0.0001). The mitral inter-commissural (IC) dimension was best predictive of annular dimensions being within range, with dimensions <30 or >50 mm resulting in a negative predictive value of 94.4%. CONCLUSIONS: MSCT-derived mitral IC dimension and LVESD easily performed measures that are effective predictors of anatomical suitability or screen failure for this tether-based TMVI device.

OBJECTIVE: To determine the prognostic impact of coronary artery disease (CAD) in patients randomized to bivalirudin or unfractionated heparin (UFH) during transcatheter aortic valve replacement (TAVR). BACKGROUND: CAD is a common comorbidity among patients undergoing TAVR and studies provide conflicting data on its prognostic impact. METHODS: The Bivalirudin on Aortic Valve Intervention Outcomes-3 (BRAVO-3) randomized trial compared the use of bivalirudin versus UFH in 802 high-surgical risk patients undergoing transfemoral TAVR for severe symptomatic aortic stenosis. Patients were stratified according to the presence or absence of history of CAD as well as periprocedural anticoagulation. The coprimary endpoints were net adverse cardiac events (NACE; a composite of all-cause mortality, myocardial infarction, stroke, or major bleeding) and major Bleeding Academic Research Consortium (BARC) bleeding ≥3b at 30 days postprocedure. RESULTS: Among 801 patients, 437 (54.6%) had history of CAD of whom 223 (51.0%) received bivalirudin. There were no significant differences in NACE (adjusted odds ratio [OR]: 1.04; 95% confidence interval [CI]: 0.69-1.58) or BARC ≥ 3b bleeding (adjusted OR: 0.84; 95% CI: 0.51-1.39) in patients with vs without CAD at 30 days. Among CAD patients, periprocedural use of bivalirudin was associated with similar NACE (OR: 0.80; 95% CI: 0.47-1.35) and BARC ≥ 3b bleeding (OR: 0.64; 95% CI: 0.33-1.25) compared with UFH, irrespective of history of CAD (p-interaction = 0.959 for NACE; p-interaction = 0.479 for major bleeding). CONCLUSION: CAD was not associated with a higher short-term risk of NACE or major bleeding after TAVR. Periprocedural anticoagulation with bivalirudin did not show any advantage over UFH in patients with and without CAD.

BACKGROUND: Mitral valve-in-valve (ViV) and valve-in-ring (ViR) are alternatives to surgical reoperation in patients with recurrent mitral valve failure after previous surgical valve repair or replacement. Our aim was to perform a large-scale analysis examining midterm outcomes after mitral ViV and ViR. METHODS: Patients undergoing mitral ViV and ViR were enrolled in the Valve-in-Valve International Data Registry. Cases were performed between March 2006 and March 2020. Clinical endpoints are reported according to the Mitral Valve Academic Research Consortium (MVARC) definitions. Significant residual mitral stenosis (MS) was defined as mean gradient ≥10 mm Hg and significant residual mitral regurgitation (MR) as ≥ moderate. RESULTS: A total of 1079 patients (857 ViV, 222 ViR; mean age 73.5±12.5 years; 40.8% male) from 90 centers were included. Median STS-PROM score 8.6%; median clinical follow-up 492 days (interquartile range, 76-996); median echocardiographic follow-up for patients that survived 1 year was 772.5 days (interquartile range, 510-1211.75). Four-year Kaplan-Meier survival rate was 62.5% in ViV versus 49.5% for ViR (P<0.001). Mean gradient across the mitral valve postprocedure was 5.7±2.8 mm Hg (≥5 mm Hg; 61.4% of patients). Significant residual MS occurred in 8.2% of the ViV and 12.0% of the ViR patients (P=0.09). Significant residual MR was more common in ViR patients (16.6% versus 3.1%; P<0.001) and was associated with lower survival at 4 years (35.1% versus 61.6%; P=0.02). The rates of Mitral Valve Academic Research Consortium-defined device success were low for both procedures (39.4% total; 32.0% ViR versus 41.3% ViV; P=0.01), mostly related to having postprocedural mean gradient ≥5 mm Hg. Correlates for residual MS were smaller true internal diameter, younger age, and larger body mass index. The only correlate for residual MR was ViR. Significant residual MS (subhazard ratio, 4.67; 95% CI, 1.74-12.56; P=0.002) and significant residual MR (subhazard ratio, 7.88; 95% CI, 2.88-21.53; P<0.001) were both independently associated with repeat mitral valve replacement. CONCLUSIONS: Significant residual MS and/or MR were not infrequent after mitral ViV and ViR procedures and were both associated with a need for repeat valve replacement. Strategies to improve postprocedural hemodynamics in mitral ViV and ViR should be further explored.

BACKGROUND: Diabetes Mellitus (DM) affects a third of patients with symptomatic severe aortic valve stenosis undergoing transcatheter aortic valve implantation (TAVI). DM is a well-known risk factor for cardiac surgery, but its prognostic impact in TAVI patients remains controversial. This study aimed to evaluate outcomes in diabetic patients undergoing TAVI. METHODS: This multicentre registry includes data of > 12,000 patients undergoing transfemoral TAVI. We assessed baseline patient characteristics and clinical outcomes in patients with DM and without DM. Clinical outcomes were defined by the second valve academic research consortium. Propensity score matching was applied to minimize potential confounding. RESULTS: Of the 11,440 patients included, 31% (n = 3550) had DM and 69% (n = 7890) did not have DM. Diabetic patients were younger but had an overall worse cardiovascular risk profile than non-diabetic patients. All-cause mortality rates were comparable at 30 days (4.5% vs. 4.9%, RR 0.9, 95%CI 0.8-1.1, p = 0.43) and at one year (17.5% vs. 17.4%, RR 1.0, 95%CI 0.9-1.1, p = 0.86) in the unmatched population. Propensity score matching obtained 3281 patient-pairs. Also in the matched population, mortality rates were comparable at 30 days (4.7% vs. 4.3%, RR 1.1, 95%CI 0.9-1.4, p = 0.38) and one year (17.3% vs. 16.2%, RR 1.1, 95%CI 0.9-1.2, p = 0.37). Other clinical outcomes including stroke, major bleeding, myocardial infarction and permanent pacemaker implantation, were comparable between patients with DM and without DM. Insulin treated diabetics (n = 314) showed a trend to higher mortality compared with non-insulin treated diabetics (n = 701, Hazard Ratio 1.5, 95%CI 0.9-2.3, p = 0.08). EuroSCORE II was the most accurate risk score and underestimated 30-day mortality with an observed-expected ratio of 1.15 in DM patients, STS-PROM overestimated actual mortality with a ratio of 0.77 and Logistic EuroSCORE with 0.35. CONCLUSION: DM was not associated with mortality during the first year after TAVI. DM patients undergoing TAVI had low rates of mortality and other adverse clinical outcomes, comparable to non-DM TAVI patients. Our results underscore the safety of TAVI treatment in DM patients. TRIAL REGISTRATION: The study is registered at clinicaltrials.gov (NCT03588247).

OBJECTIVES: The clinical and cost-saving benefits of transcatheter aortic valve implantation (TAVI) over surgical aortic valve replacement (SAVR) in patients with severe aortic stenosis who are at high or intermediate risk of surgical mortality are supported by a growing evidence base. The PARTNER 3 trial (Placement of AoRTic TraNscathetER Valve Trial) demonstrated clinical benefits with SAPIEN 3 TAVI compared with SAVR in selected patients at low risk of surgical mortality. This study uses PARTNER 3 outcomes in combination with a French national hospital claim database to inform a cost-utility model and examine the cost implications of TAVI over SAVR in a low-risk population. METHODS: A 2-stage cost-utility analysis was developed to estimate changes in both direct healthcare costs and health-related quality of life using TAVI with SAPIEN 3 compared with SAVR. Early adverse events associated with TAVI were captured using the PARTNER 3 data set. These data fed into a Markov model that captured longer-term outcomes of patients, after TAVI or SAVR intervention. RESULTS: TAVI with SAPIEN 3 offers meaningful benefits over SAVR in providing both cost saving (12 742 per patient) and generating greater quality-adjusted life-years (0.89 per patient). These results are robust with TAVI with SAPIEN 3 remaining dominant across several scenarios and deterministic and probabilistic sensitivity analyses. CONCLUSIONS: This model demonstrated that TAVI with SAPIEN 3 was dominant compared with SAVR in the treatment of patients with severe symptomatic aortic stenosis who are at low risk of surgical mortality. These findings should help policy makers in developing informed approaches to intervention selection for this patient population.

OBJECTIVES: To determine the prognostic impact of anemia in patients randomized to bivalirudin or unfractionated heparin (UFH) during transcatheter aortic valve replacement (TAVR). BACKGROUND: Whether the periprocedural use of bivalirudin as compared with UFH in anemic patients undergoing TAVR has an impact on outcomes remains unknown. METHODS: The BRAVO-3 trial compared the use of bivalirudin versus UFH in 802 high risk patients undergoing transfemoral TAVR for severe symptomatic aortic stenosis. Patients were stratified according to the presence (defined as hemoglobin levels <13 g/dl in men and <12 g/dl in women) or absence of anemia. The primary outcomes were net adverse cardiac events (NACE; a composite of all-cause mortality, myocardial infarction, stroke, or bleeding) and major bleeding (Bleeding Academic Research Consortium ≥3b) at 30 days. RESULTS: Among 798 patients with available baseline hemoglobin levels, 427 (54%) were anemic of whom 221 (52%) received bivalirudin. There were no significant differences in NACE and major bleeding at 30 days between patients with and without anemia, irrespective of the type of anticoagulant used (pinteraction = 0.71 for NACE, pinteraction = 1.0 for major bleeding). However, anemic patients had a higher risk of major vascular complications (adjusted OR 2.43, 95% CI 1.42-4.16, p = 0.001), and acute kidney injury (adjusted OR 1.74, 95% CI 1.16-2.59, p = 0.007) compared to non-anemic patients at 30 days. CONCLUSIONS: Anemia was not associated with a higher risk of NACE or major bleeding at 30 days after TAVR without modification of the treatment effects of periprocedural anticoagulation with bivalirudin versus UFH.

OBJECTIVES: To describe the incidence, predictors, and clinical impact of permanent pacemaker insertion (PPI) following transcatheter aortic valve replacement (TAVR) in women. BACKGROUND: Data on pacemaker insertion complicating TAVR in women are scarce. METHODS: The Women's International Transcatheter Aortic Valve implantation (WIN-TAVI) is a prospective registry evaluating the safety and efficacy of TAVR in women. We included patients without preprocedural pacemakers and divided them into two groups: (1) PPI and (2) no-PPI. We identified PPI predictors using logistic regression and studied its clinical impact on the Valve Academic Research Consortium (VARC)-2 efficacy and safety endpoints. RESULTS: Out of 1019 patients, 922 were included in the analysis. Post-TAVR PPI occurred in 132 (14.3%) patients. Clinical and procedural characteristics were similar in both groups. Pre-existing right bundle branch block (RBBB) was associated with a high risk of post-TAVR PPI (OR 3.62, 95% CI 1.85-7.06, p < 0.001), while implantation of balloon-expandable prosthesis was associated with a lower risk (OR 0.47, 95% CI 0.30-0.74, p < 0.001). Post-TAVR PPI prolonged in-hospital stay by a median of 2 days (11 [9-16] days in PPI vs. 9 [7-14] days in no-PPI, p = 0.005), yet risks of VARC-2 efficacy and safety endpoints at 1 year were similar in both groups (adj HR 0.95, 95% CI 0.60-1.52, p = 0.84 and adj HR 1.22, 95% CI 0.83-1.79, p = 0.31, respectively). CONCLUSION: Pacemaker implantation following TAVR is frequent among women and is associated with pre-existing RBBB and valve type. PPI prolongs hospital stay, albeit without any significant impact on 1-year outcomes.

OBJECTIVE: To evaluate the incidence, predictors and outcomes of female patients with patient-prosthesis mismatch (PPM) following transcatheter aortic valve intervention (TAVI) for severe aortic stenosis (AS). BACKGROUND: Female AS TAVI recipients have a significantly lower mortality than surgical aortic valve replacement (SAVR) recipients, which could be attributed to the potentially lower PPM rates. TAVI has been associated with lower rates of PPM compared to SAVR. PPM in females post TAVI has not been investigated to date. METHODS: The WIN-TAVI (Women's INternational Transcatheter Aortic Valve Implantation) registry is a multicenter registry of women undergoing TAVR for severe symptomatic AS. Two hundred and fifty patients with detailed periprocedural and follow-up echocardiographic investigations were included in the WIN-TAVI echocardiographic sub-study. PPM was defined as per European guidelines stratified by the presence of obesity. RESULTS: The incidence of PPM in our population was 32.8%. Patients with PPM had significantly higher BMI (27.4 ± 6.1 vs. 25.2 ± 5.0, p = .002), smaller sized valves implanted (percentage of TAVI ≤23 mm 61% vs. 29.2%, PPM vs. no PPM, p < .001) and were more often treated with balloon expandable valves (48.3 vs. 32.5%, p < .001) rather than self expanding ones (26.3 vs. 52.8%, <.001). BMI (OR = 1.08; 95%CI 1.02-1.14, p = .011) and valve size ≤23 mm (OR = 3.00 95%CI 1.14-7.94, p = .027) were the only independent predictors of PPM. There was no significant interaction between valve size and valve type (p = .203). No significant differences were observed in 1-year mortality or major adverse cardiovascular events. CONCLUSIONS: PPM in females undergoing TAVI occurs in one third of patients. BMI and valve size ≤23 mm are independent predictors. Larger registries are required to determine the impact of PPM on future clinical outcomes.

OBJECTIVES: To assess the impact of anemia on clinical outcomes in female patients enrolled in the Women's InterNational transcatheter aortic valve implantation (WIN-TAVI) registry. BACKGROUND: Anemia is highly prevalent among females who constitute half of TAVI candidates, yet, its clinical significance remains poorly investigated. METHODS: Patients were divided into three groups according to preprocedural hemoglobin (Hb) level: (1) no anemia (Hb ≥12 g/dl), (2) mild-to-moderate anemia (10 ≤ Hb <12 g/dl), and (3) severe anemia (Hb <10 g/dl). The primary outcome was the occurrence of Valve Academic Research Consortium (VARC)-2 efficacy endpoint, a composite of mortality, stroke, myocardial infarction (MI), hospitalization for valve-related symptoms or heart failure or valve-related dysfunction at 1-year follow-up. RESULTS: Hemoglobin level was available in 877 (86.1%) patients: 412 (47.0%) had no anemia, 363 (41.4%) had mild-to-moderate anemia, and 102 (11.6%) had severe anemia. The latter group had a higher prevalence of cardiovascular risk factors. Compared with patients without anemia, severe anemia was associated with a greater risk of VARC-2 efficacy endpoint (adj HR 1.71, 95% CI: 1.02-2.87, p = .04), all-cause death (adj HR 2.36, 95% CI: 1.31-4.26, p = .004) and a composite of death, MI or stroke (adj HR 1.88, 95% CI: 1.10-3.22, p = .02) at 1 year. Moreover, an increased risk of late mortality (adj HR 1.15, 95% CI: 1.02-1.30, p = .03) was observed with every 1 g/dl decrease in hemoglobin level. CONCLUSION: Severe anemia in females undergoing TAVI was independently associated with increased rates of VARC-2 efficacy endpoint and mortality at 1 year.

BACKGROUND: Limited data suggest that transcatheter (TAVR) as compared with surgical aortic valve replacement (SAVR) may be more effective in female than male patients. To date, most evidence is derived from subgroup analyses of large trials, and a dedicated randomized trial evaluating whether there is a difference in outcomes between these interventions in women is warranted. The RHEIA trial will compare the safety and efficacy of TAVR with SAVR in women with severe symptomatic aortic stenosis requiring aortic valve intervention, irrespective of surgical risk. METHODS/DESIGN: The RHEIA trial is a prospective, randomized, controlled study that will enroll up to 440 patients across 35 sites in Europe. Women with severe symptomatic aortic stenosis, with any but prohibitive surgical risk status, will be randomized 1:1 to undergo aortic valve intervention with either transfemoral TAVR with the SAPIEN 3 or SAPIEN 3 Ultra device or SAVR and followed up for 1 year. The objective is to determine whether TAVR is non-inferior to SAVR in this patient population and, if this is fulfilled whether TAVR is actually superior to SAVR. The primary safety/efficacy endpoint is a composite of all-cause mortality, all stroke, and re-hospitalization (for valve or procedure-related symptoms or worsening congestive heart failure) at 1 year post-procedure. Other outcomes (assessed at 30 days and/or 1 year) include all-cause mortality; bleeding, vascular, cardiac, cerebrovascular and renal complications; aortic valve prosthesis and left ventricular function; cognitive function, health status, and quality of life. DISCUSSION: The RHEIA study has been designed to evaluate the safety and efficacy of TAVR compared with SAVR specifically in women with severe symptomatic aortic stenosis, irrespective of the level of surgical risk. The results will be the first to provide specific randomized evidence to guide treatment selection in female patients with severe symptomatic aortic stenosis.

OBJECTIVES: Aim of this study is to evaluate safety, feasibility, and mid-term outcome of transcatheter aortic valve implantation (TAVI) in cardiogenic shock (CS). BACKGROUND: Balloon aortic valvuloplasty in patients with severe aortic valve stenosis (SAS) complicated by CS is indicated but associated with a grim prognosis. TAVI might be a more reasonable treatment option in this setting but data are scant. METHODS: From March 2008 to February 2019, 51 patients with severe aortic valvulopathy (native SAS or degenerated aortic bioprosthesis) and CS treated by TAVI in 11 European centers were included in this multicenter registry. Demographic, clinical, and procedural data were collected, as well as clinical and echocardiographic follow-up. RESULTS: The mean age of our study population was 75.8 ± 13, 49% were women, and mean Society of Thoracic Surgeons (STS) score was 19 ± 15%. Device success was achieved in 94.1%, with a 5% incidence of moderate/severe paravalvular leak. The 30-day events were mortality 11.8%, stroke 2.0%, vascular complications 5.9%, and acute kidney injury 34%. Valve Academic Research Consortium-2 early safety endpoint was reached in 35.3% of cases. At 1-year of follow-up, the mortality rate was 25.7% and the readmission for congestive heart failure was 8.6%. CONCLUSIONS: TAVI seems to be a therapeutic option for patients with CS and SAS or degenerated aortic bioprosthesis in terms of both safety and efficacy at early and long-term follow-up.

Aims: The aim of this study was to compare clinical outcomes of patients undergoing transfemoral transcatheter aortic valve implantation (TAVI) with balloon-expandable (BE) valves vs. self-expandable (SE) valves. Transcatheter aortic valve implantation is a minimally invasive and lifesaving treatment in patients with aortic valve stenosis. Even though BE-valves and SE-valves are both commonly used on a large scale, adequately sized trials comparing clinical outcomes in patients with severe aortic valve stenosis treated with BE-valves compared with SE-valves are lacking. Methods and results: In this CENTER-collaboration, data from 10 registries or clinical trials, selected through a systematic search, were pooled and analysed. Propensity score methodology was used to reduce treatment selection bias and potential confounding. The primary endpoints were mortality and stroke at 30 days follow-up in patients treated with BE-valves compared with SE-valves. Secondary endpoints included clinical outcomes, e.g. bleeding during hospital admission. All outcomes were split for early-generation BE-valves compared with early-generation SE-valves and new-generation BE-valves with new-generation SE-valves. The overall patient population (N = 12 381) included 6239 patients undergoing TAVI with BE-valves and 6142 patients with SE-valves. The propensity matched population had a mean age of 81 ± 7 years and a median STS-PROM score or 6.5% [interquartile range (IQR) 4.0-13.0%]. At 30-day follow-up, the mortality rate was not statistically different in patients undergoing TAVI with BE-valves compared with SE-valves [BE: 5.3% vs. SE: 6.2%, relative risk (RR) 0.9; 95% confidence interval (CI) 0.7-1.0, P = 0.10]. Stroke occurred less frequently in patients treated with BE-valves (BE: 1.9% vs. SE: 2.6%, RR 0.7; 95% CI 0.5-1.0, P = 0.03). Also, patients treated with BE-valves had a three-fold lower risk of requiring pacemaker implantation (BE: 7.8% vs. SE: 20.3%, RR 0.4; 95% CI 0.3-0.4, P < 0.001). In contrast, patients treated with new-generation BE-valves more frequently experienced major and life-threatening bleedings compared with new-generation SE-valves (BE: 4.8% vs. SE: 2.1%, RR 2.3; 95% CI 1.6-3.3, P < 0.001). Conclusion: In this study, which is the largest study to compare valve types in TAVI, we demonstrated that the incidence of stroke and pacemaker implantation was lower in patients undergoing transfemoral TAVI with BE-valves compared with SE-valves. In contrast, patients treated with new-generation BE-valves more often suffered from major or life-threatening bleedings than patients with new-generation SE-valves. Mortality at 30-days was not statistically different in patients treated with BE-valves compared with SE-valves. This study was a propensity-matched analysis generated from observational data, accordingly current outcomes will have to be confirmed in a large scale randomized controlled trial.

BACKGROUND: Postprocedural aortic regurgitation occurs in 10 to 20% of patients undergoing transcatheter aortic-valve replacement (TAVR) for aortic stenosis. We hypothesized that assessment of defects in high-molecular-weight (HMW) multimers of von Willebrand factor or point-of-care assessment of hemostasis could be used to monitor aortic regurgitation during TAVR. METHODS: We enrolled 183 patients undergoing TAVR. Patients with aortic regurgitation after the initial implantation, as identified by means of transesophageal echocardiography, underwent additional balloon dilation to correct aortic regurgitation. HMW multimers and the closure time with adenosine diphosphate (CT-ADP), a point-of-care measure of hemostasis, were assessed at baseline and 5 minutes after each step of the procedure. Mortality was evaluated at 1 year. A second cohort (201 patients) was studied to validate the use of CT-ADP in order to identify patients with aortic regurgitation. RESULTS: After the initial implantation, HMW multimers normalized in patients without aortic regurgitation (137 patients). Among the 46 patients with aortic regurgitation, normalization occurred in 20 patients in whom additional balloon dilation was successful but did not occur in the 26 patients with persistent aortic regurgitation. A similar sequence of changes was observed with CT-ADP. A CT-ADP value of more than 180 seconds had sensitivity, specificity, and negative predictive value of 92.3%, 92.4%, and 98.6%, respectively, for aortic regurgitation, with similar results in the validation cohort. Multivariable analyses showed that the values for HMW multimers and CT-ADP at the end of TAVR were each associated with mortality at 1 year. CONCLUSIONS: The presence of HMW-multimer defects and a high value for a point-of-care hemostatic test, the CT-ADP, were each predictive of the presence of aortic regurgitation after TAVR and were associated with higher mortality 1 year after the procedure.

OBJECTIVES: To evaluate the impact of coronary artery disease (CAD) with or without recent (≤ 30 days) percutaneous coronary intervention (PCI) in women undergoing transcatheter aortic valve replacement (TAVR). BACKGROUND: Although women display a specific risk-profile for both PCI and TAVR, the impact of CAD and PCI in the setting of TAVR in women is unclear. METHODS: The multinational Women's International Transcatheter Aortic Valve implantation registry enrolled consecutive female patients undergoing contemporary TAVR in 19 centers between 2013 and 2015. Patients with available coronary angiography or CT scan in the pre-operative assessment of TAVR were categorized as without CAD, with CAD but no recent PCI and CAD and recent PCI (≤30 days). All events were adjudicated according to the VARC-2 criteria. RESULTS: A total of 787 patients were included in this analysis, among whom 459 (58.3%) had no CAD, 247 (31.4%) had CAD without recent PCI and 81 (10.3%) underwent recent PCI (≤ 30 days before TAVR). After multivariable adjustment, both groups of CAD patients, without and with recent PCI, presented with higher risk of death, myocardial infarction or stroke, compared with patients without CAD (adj HR 1.56, 95%CI 1.03-2.39, P = 0.038 and adj HR 1.96, 95% CI 1.1-3.5, P = .021, respectively). Patients with recent PCI had increased risk of all-cause death (adj HR 1.89, 95% CI 1.0-3.5, P = 0.04) and stroke (adj HR 3.7, 95% CI 1.0-13.5, P = 0.046) compared with patients without CAD. CONCLUSION: The presence of CAD in women undergoing TAVR, with or without recent PCI, was associated with long-term poorer outcomes.

BACKGROUND/OBJECTIVE: Prostar XL (PS) and ProGlide (PG) are common vascular closure devices (VCD) used in TAVR via transfemoral vascular approach. The impact of these VCD on vascular and bleeding complications remains unclear. METHODS: The BRAVO-3 trial randomized 802 patients undergoing transfemoral TAVR. We stratified patients according to type of VCD used and examined the 30-day incidence of major or minor vascular complications, major bleeding (BARC ≥3b), AKI and major adverse cardiac and cerebrovascular events (MACCE; death, myocardial infarction or stroke). RESULTS: A total of 746 (93%) patients were treated with either PS (n = 352, 47%) or PG (n = 394, 53%) VCD, without significant differences in successful deployment rate (PS 322 [91.2%] vs. PG 373 [94.2%] respectively, p = .20). PG was associated with a significantly lower incidence of major or minor vascular complications, compared to PS (adjusted OR: 0.54; 95% CI: 0.37-0.80; p < .01). Rates of acute kidney injury were also lower with the PG device. There was no significant difference between bleeding, MACCE, and death. CONCLUSIONS: Compared to PS, the PG VCD was associated with a lower rate of major or minor vascular complications and lower rates of AKI after transfemoral TAVR.
