ABSTRACT
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.

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: The risks of prefrail and frail women undergoing transcatheter aortic valve replacement (TAVR) have not been fully examined. The aim of the analysis was to assess the prognostic impact of prefrailty and frailty in women undergoing TAVR. METHODS: Women at intermediate or high surgical risk with severe aortic stenosis undergoing TAVR from the prospective multicentre WIN-TAVI (Women's International Transcatheter Aortic Valve Implantation) registry were stratified based on the number of Fried frailty criteria (weight loss, exhaustion, low physical activity, slow gait, weakness) met: nonfrail (no criteria), prefrail (1 or 2 criteria), or frail (3 or more criteria). The primary outcome at 1 year was the Valve Academic Research Consortium 2 (VARC-2) efficacy end point, a composite of mortality, stroke, myocardial infarction, hospitalisation for valve-related symptoms or heart failure, and valve-related dysfunction; secondary outcomes included the composite of VARC-2 life-threatening or major bleeding. RESULTS: Out of 1019 women, 297 (29.1%) met at least 1 frailty criterion: 264 (25.9%) had prefrailty and 33 (3.2%) frailty. The 1-year risk of the primary outcome was significantly higher in prefrail and frail (20.2%) than in nonfrail (14.9%) women (adjusted hazard ratio [aHR] 1.51, 95% confidence interval [CI] 1.07-2.12). The risk of VARC-2 life-threatening or major bleeding was higher in prefrail or frail (19.9%) than in nonfrail (10.0%) women (aHR 2.06, 95% CI 1.42-2.97). These risks were consistently increased in the prefrail and frail groups assessed separately. CONCLUSIONS: In women undergoing TAVR, the presence of prefrailty or frailty conferred an increased risk of the VARC-2 efficacy end point and of VARC-2 life-threatening or major bleeding.

Background/Objectives: To date, data regarding the characteristics and management of obstructive, stable coronary artery disease (CAD) encountered in patients undergoing transcatheter aortic valve implantation (TAVI) are sparse. The aim of the study was to analyze granular details, treatment, and outcomes of patients undergoing TAVI with obstructive, stable CAD from real-world practice. Methods: REVASC-TAVI (Management of myocardial REVASCularization in patients undergoing Transcatheter Aortic Valve Implantation with coronary artery disease) is an investigator-initiated, multicenter registry, which collected data from patients undergoing TAVI with obstructive stable CAD found during the pre-TAVI work-up. Results: A total of 2025 patients from 30 centers worldwide with complete follow-up were included in the registry. Most patients had single-vessel CAD (56.1%). An involvement of proximal coronary tracts was detected in 62.5% of cases, with 12.0% of patients having CAD in left main (LM). Most patients received percutaneous coronary intervention (PCI) (n = 1617, 79.9%), especially those with proximal CAD (90.4%). At 2 years, the rates of all-cause death [Kaplan-Meier (KM) estimates 20.1% vs. 18.8%, plog-rank = 0.86] and of the composite of all-cause death, stroke, myocardial infarction, and rehospitalization for heart failure (KM estimates 29.7% vs. 27.5%, plog-rank = 0.82) did not differ between patients undergoing PCI and those who were not. Conclusions: Patients undergoing TAVI with obstructive CAD more commonly had a single-vessel disease and an involvement of proximal coronary tracts. They were commonly treated with PCI, with similar outcomes compared to those treated conservatively.
ABSTRACT
OBJECTIVES: We evaluated transcatheter aortic valve Implantation (TAVI) in high-risk patients with severe aortic regurgitation (AR) in native or degenerated bioprosthetic valves. BACKGROUND: TAVI has emerged as a viable treatment modality for severe aortic stenosis in inoperable or high-risk patients. The use of TAVI for treatment of severe AR has remained largely unexplored. METHODS: Eight patients (age 79.6 years ± 5.75 years) with severe AR underwent TAVI at six tertiary hospitals between April 2010 and May 2011. All patients were considered to be at prohibitive risk for surgical aortic valve replacement (SAVR).TAVI with the nitinol based Core Valve bioprosthesis (CRS) (Medtronic) was performed in all patients. RESULTS: Transfemoral access was used in all cases. Procedural success was obtained in all cases without any intraprocedural complications. There was no in hospital or 30-day mortality. There were no cases of atrioventricular blocks requiring permanent pacemaker implantation. At a mean follow up of 15.5 ± 15 months; all patients had improvement in New York Heart Association functional class. Follow up echocardiography revealed improved or stable left ventricular ejection fraction and optimal device function in all cases. CONCLUSIONS: TAVI with the CRS bioprosthesis is feasible and effective in appropriately selected cases of severe aortic regurgitation in native and bioprosthetic aortic valves.

BACKGROUND: Bioresorbable scaffolds (BRS) have been introduced to overcome the limitations of drug-eluting stents and the ABSORB (Everolimus-Eluting BRS, Abbott Vascular, Santa Clara, CA, USA) was the most extensively tested. Nevertheless, major RCTs reported higher rates of target lesion failures and BRS thrombosis at 3 years follow-up, bringing to the withdrawing of the device from the market. It has been suggested that a better lesions selection and an optimized implantation technique could mitigate the displayed adverse results. METHODS: Consecutive patients undergoing BRS implantation were included in this observational, single center study. Clinical follow-up was conducted up to 4 years. Endpoint of interest was the target lesion failure (TLF), a composite outcome including cardiac death, target vessel myocardial infarction and target lesion revascularization. RESULTS: A total of 62 patients with a mean age of 55±8.5 years were analyzed of which 70.9% presented with an acute coronary syndrome and 59.6% with myocardial infarction. A total of 100 lesions were treated and 51.6% were complex (B2/C). Predilatation was performed in all the case, post-dilatation in 74.1%. All the target vessel reference diameter (RVD) were >2.5 mm (average RVD 3.2±0.24 mm). At 4 years, the rate for TLF was 6.9%. Subgroup's analysis did not show significative differences among groups although consistently higher event rates were found for RVD <2.5 mm (12.6% vs. 6.4%, P=0.5), BRS overlapping (11.8% vs. 5%, P=0.2) and ticagrelor instead of clopidogrel on top of cardioaspirin (9.1% vs. 3%, P=0.2). CONCLUSIONS: This small-sized real-world registry displays lower rates of clinical events during long-term follow-up in respect to previous studies. The avoidance of implantation in small vessels, inclusion of acute myocardial infarction and extensive performance of BRS post-dilatation could explain the observed better results. Long-term outcomes of the ongoing ABSORB IV Trial are needed to confirm this data.

Symptoms of aortic stenosis (AS) are not proportional to its severity and patients with very severe AS (VSAS) remain asymptomatic for a long time. The appropriate time for intervention in patients with VSAS and the effects of transcatheter aortic valve implantation (TAVI) on left ventricular hypertrophy (LVH) remain debated. Our aim was to compare the procedural and 30-day outcomes of TAVI between patients with VSAS and patients with severe AS (SAS) and the changes in LVH. We selected patients with an aortic peak velocity ≥5 m/s (VSAS) and those with aortic peak velocity 4 to 5 m/s (SAS) treated with TAVI. Patients with reduced left ventricular ejection fraction (<45%) were excluded. The primary end point was the incidence of all-cause death at 30 days. The secondary end points included the 30-day incidence of cardiac death, cardiac rehospitalization, and stroke/transient ischemic attack and the changes in LVH from baseline to 30 days. A total of 102 patients in the VSAS group and 535 in the SAS group were included. Patients in the VSAS group had a thicker septal wall (p <0.001) and a higher Agaston score (p <0.001) and calcium volume (p = 0.007). No differences were observed regarding the primary and secondary clinical end points. However, patients with VSAS showed a significantly greater improvement in concentric LVH, although the prevalence of concentric LVH remained higher than in patients with SAS. TAVI in patients with VSAS showed similar procedural and clinical outcomes to patients with SAS and experienced a more pronounced improvement in the prevalence of concentric LVH.

Early menopause is associated with an increased risk of cardiovascular diseases, including aortic stenosis (AS). We sought to investigate the prevalence and impact of early menopause on clinical outcomes in patients who underwent transcatheter aortic valve implantation (TAVI) for severe symptomatic AS. Women's International TAVI is a multinational, prospective, observational registry of women who underwent TAVI for severe symptomatic AS (n = 1,019). Patients were divided into 2 groups based on age of menopause: early menopause (age ≤45 years) and regular menopause (age >45 years). The primary outcome of interest was Valve Academic Research Consortium 2 efficacy end point, a composite of mortality, stroke, myocardial infarction, hospitalization for valve-related symptoms, or heart failure or valve-related dysfunction at 1-year follow-up. Of 732 patients with available data on menopause age, 173 (23.6%) were classified as having early menopause. These patients presented for TAVI at a younger age (81.6 ± 6.9 vs 82.7 ± 5.9, p = 0.05) and had a significantly lower Society of Thoracic Surgeons score (6.6 ± 4.8 vs 8.2 ± 7.1, p = 0.03) than those with regular menopause. However, the total valve calcium volume was smaller among patients with early versus regular menopause (731.8 ± 850.9 mm3 vs 807.6 ± 633.8 mm3, p = 0.002). Other co-morbidities were similar between the 2 groups. At 1-year follow-up, there were no significant differences in clinical outcomes between patients with early versus regular menopause (hazard ratio 1.00, 95% confidence interval 0.61 to 1.63, p = 1.00). In conclusion, despite presenting for TAVI at a younger age, patients with early menopause had a similar risk of adverse events as patients with regular menopause at 1 year after TAVI.

BACKGROUND: Transcatheter aortic valve implantation (TAVI) has become an accepted treatment for patients with severe aortic stenosis (AS). Predicting which patients are at risk for adverse clinical outcomes after TAVI remains difficult, especially in women. AIM: To identify predictors of adverse events in the WIN-TAVI cohort. METHODS: The WIN-TAVI study is an observational registry of 1019 women undergoing TAVI for severe symptomatic AS. Follow-up was 1 year. The primary outcome was defined according to VARC-2: a composite of mortality, stroke, myocardial infarction or hospitalization for valve-related symptoms or heart failure. The secondary outcome was a composite of cardiovascular mortality or hospitalization for valve-related symptoms or heart failure. RESULTS: We included 1019 women with severe AS (mean age of 82.5 ± 6.3 years). At 1 year, 16.4% of the patients experienced the primary endpoint and 12.6% the secondary endpoint. The use of oral anticoagulants (OAC) was the strongest independent predictor of the primary outcome (adjusted hazard ratio [aHR] 1.51, 95% confidence interval [CI] 1.079-2.106, p = 0.016). Independent predictors of the secondary endpoint were age (aHR 1.04 per year, 95% CI 1.01-1.074, p = 0.016) and use of OAC (aHR: 1.79, 95% CI 1.24-2.60, p = 0.002). OAC use was not associated with higher bleeding risk. CONCLUSION: Pre-procedural use of OAC was the strongest predictor of adverse outcomes during 1-year follow-up, likely reflecting a combination of high-risk factors and comorbidities, but was not related to increased bleeding risk.

BACKGROUND: Mitral valve-in-valve (ViV) is associated with suboptimal hemodynamics and rare left ventricular outflow tract (LVOT) obstruction. OBJECTIVES: This study aimed to determine whether device position and asymmetry are associated with these outcomes. METHODS: Patients undergoing SAPIEN 3 (Edwards Lifesciences) mitral ViV included in the VIVID (Valve-in-Valve International Data) Registry were studied. Clinical endpoints are reported according to Mitral Valve Academic Research Consortium definitions. Residual mitral valve stenosis was defined as mean gradient ≥5 mm Hg. Depth of implantation (percentage of transcatheter heart valve [THV] atrial to the bioprosthesis ring) and asymmetry (ratio of 2 measures of THV height) were evaluated. RESULTS: A total of 222 patients meeting the criteria for optimal core lab evaluation were studied (age 74 ± 11.6 years; 61.9% female; STS score = 8.3 ± 7.1). Mean asymmetry was 6.2% ± 4.4%. Mean depth of implantation was 19.0% ± 10.3% atrial. Residual stenosis was common (50%; mean gradient 5.0 ± 2.6 mm Hg). LVOT obstruction occurred in 7 cases (3.2%). Implantation depth was not a predictor of residual stenosis (OR: 1.19 [95% CI: 0.92-1.55]; P = 0.184), but more atrial implantation was protective against LVOT obstruction (0.7% vs 7.1%; P = 0.009; per 10% atrial, OR: 0.48 [95% CI: 0.24-0.98]; P = 0.044). Asymmetry was found to be an independent predictor of residual stenosis (per 10% increase, OR: 2.30 [95% CI: 1.10-4.82]; P = 0.027). CONCLUSIONS: Valve stenosis is common after mitral ViV. Asymmetry was associated with residual stenosis. Depth of implantation on its own was not associated with residual stenosis but was associated with LVOT obstruction. Technical considerations to reduce postdeployment THV asymmetry should be considered.

BACKGROUND: The optimal access route in patients with severe peripheral artery disease (PAD) undergoing transcatheter aortic valve replacement (TAVR) remains undetermined. OBJECTIVES: This study sought to compare clinical outcomes with transfemoral access (TFA), transthoracic access (TTA), and nonthoracic transalternative access (TAA) in TAVR patients with severe PAD. METHODS: Patients with PAD and hostile femoral access (TFA impossible, or possible only after percutaneous treatment) undergoing TAVR at 28 international centers were included in this registry. The primary endpoint was the propensity-adjusted risk of 30-day major adverse events (MAE) defined as the composite of all-cause mortality, stroke/transient ischemic attack (TIA), or main access site-related Valve Academic Research Consortium 3 major vascular complications. Outcomes were also stratified according to the severity of PAD using a novel risk score (Hostile score). RESULTS: Among the 1,707 patients included in the registry, 518 (30.3%) underwent TAVR with TFA after percutaneous treatment, 642 (37.6%) with TTA, and 547 (32.0%) with TAA (mostly transaxillary). Compared with TTA, both TFA (adjusted HR: 0.58; 95% CI: 0.45-0.75) and TAA (adjusted HR: 0.60; 95% CI: 0.47-0.78) were associated with lower 30-day rates of MAE, driven by fewer access site-related complications. Composite risks at 1 year were also lower with TFA and TAA compared with TTA. TFA compared with TAA was associated with lower 1-year risk of stroke/TIA (adjusted HR: 0.49; 95% CI: 0.24-0.98), a finding confined to patients with low Hostile scores (Pinteraction = 0.049). CONCLUSIONS: Among patients with PAD undergoing TAVR, both TFA and TAA were associated with lower 30-day and 1-year rates of MAE compared with TTA, but 1-year stroke/TIA rates were higher with TAA compared with TFA.

BACKGROUND: The optimal timing to perform percutaneous coronary interventions (PCI) in transcatheter aortic valve implantation (TAVI) patients remains unknown. AIMS: We sought to compare different PCI timing strategies in TAVI patients. METHODS: The REVASC-TAVI registry is an international registry including patients undergoing TAVI with significant, stable coronary artery disease (CAD) at preprocedural workup. In this analysis, patients scheduled to undergo PCI before, after or concomitantly with TAVI were included. The main endpoints were all-cause death and a composite of all-cause death, stroke, myocardial infarction (MI) or rehospitalisation for congestive heart failure (CHF) at 2 years. Outcomes were adjusted using the inverse probability treatment weighting (IPTW) method. RESULTS: A total of 1,603 patients were included. PCI was performed before, after or concomitantly with TAVI in 65.6% (n=1,052), 9.8% (n=157) or 24.6% (n=394), respectively. At 2 years, all-cause death was significantly lower in patients undergoing PCI after TAVI as compared with PCI before or concomitantly with TAVI (6.8% vs 20.1% vs 20.6%; p<0.001). Likewise, the composite endpoint was significantly lower in patients undergoing PCI after TAVI as compared with PCI before or concomitantly with TAVI (17.4% vs 30.4% vs 30.0%; p=0.003). Results were confirmed at landmark analyses considering events from 0 to 30 days and from 31 to 720 days. CONCLUSIONS: In patients with severe aortic stenosis and stable coronary artery disease scheduled for TAVI, performance of PCI after TAVI seems to be associated with improved 2-year clinical outcomes compared with other revascularisation timing strategies. These results need to be confirmed in randomised clinical trials.

AIMS: To investigate the impact of the right ventricle to pulmonary artery (RV-PA) coupling on the outcome of patients undergoing transcatheter aortic valve intervention (TAVI), and to describe changes in right ventricular function, pulmonary hypertension, and their ratio after TAVI. METHODS: Three hundred and seventy-seven patients from the Italian ClinicalService Project, who underwent TAVI between February 2011 and August 2020, were included. Tricuspid annular plane systolic excursion/pulmonary artery systolic pressure (TAPSE/PASP) ratio was retrospectively calculated as a surrogate of RV-PA coupling. The population was stratified according to TAPSE/PASP using a cut-off of 0.36âmm/mmHg derived from a receiving operating characteristic (ROC) curve. The primary end point was 6-month all-cause death. RESULTS: Compared with patients with a TAPSE/PASP ratio ≥0.36âmm/mmHg (81%), those with TAPSE/PASP ratio <0.36âmm/mmHg (19%) had more comorbidities and were more symptomatic.Moreover, they were more likely to receive general anesthesia and an old generation device. Device success was similar between the two groups. A TAPSE/PASP ratio <0.36âmm/mmHg was associated with a higher risk of all-cause death at 6-months (17.3% versus 5.3%; adjusted HR 2.66; P = 0.041). The prognostic impact of the TAPSE/PASP ratio was stronger than the impact of TAPSE and PASP as separate parameters and was independent of the surgical risk score. Both TAPSE, PASP, and their ratio improved from baseline to 1 month and 6 months after TAVI. CONCLUSIONS: A TAPSE/PASP ratio <0.36âmm/mmHg is strongly associated with an increased risk of mortality after TAVI. Providing a left ventricle unloading, TAVI is associated with improvement of both TAPSE, PASP, and their ratio.

BACKGROUND: The differential outcomes between pure/predominant aortic stenosis (AS) and mixed aortic valve disease (MAVD) in patients undergoing transcatheter aortic valve implantation (TAVI) are still debated. OBJECTIVE: To evaluate the comparative clinical outcomes of patients with MAVD and AS undergoing TAVI using data from the RISPEVA registry. METHODS: A total of 3263 patients were included. Of the 3263 patients, 656 with concomitant moderate/severe aortic regurgitation constituted the MAVD group and 2607 constituted the AS cohort. Primary endpoints were 30-day mortality and 1-year survival. Postprocedural paravalvular regurgitation (PPVR), cerebrovascular events, bleeding, and vascular complications were assessed at 30 days. RESULTS: In the overall population, 30-day mortality in the MAVD group was higher than in AS patients (4.3% vs 2.6%;P=.02); however, no differences were detected after propensity-score matching (4.1% vs 3.5%; P=.62). One-year survival was comparable between MAVD and AS patients in both unmatched and matched cohorts. Left ventricular ejection fraction, pulmonary artery systolic pressure, and PPVR, but not baseline MAVD, were predictors of 30-day mortality. The incidence of PPVR was higher in the MAVD group vs the AS group; this difference was not confirmed in patients implanted with a balloon-expandable device. CONCLUSION: MAVD per se did not negatively affect patients' prognoses, but appears to identify a more complex cohort of patients with a worse clinical and functional status, probably referred to TAVI in a later stage of the disease. Patients with MAVD had a greater propensity to develop PPVR, which is a known predictor of worse outcome; this tendency seems to be mitigated by the implantation of balloon-expandable valves.

Objectives: This study aimed to explore the correlation between left ventricular (LV) myocardial work (MW) indices and invasively-derived LV stroke work index (SWI) in a cohort of patients with advanced heart failure (AHF) considered for heart transplantation. Background: Left ventricular MW has emerged as a promising tool for diagnostic and prognostic purposes in heart failure (HF) but its relationship with hemodynamic data derived from right heart catheterization (RHC) has not been assessed in patients with advanced heart failure yet. Materials and methods: Consecutive patients with AHF considered for heart transplantation from 2016 to 2021 performing RHC and echocardiography as part of the workup were included. Conventional LV functional parameters and LV MW indices, including LV global work index (GWI), LV global constructive work (GCW), LV global wasted work (GWW), LV global work efficiency (GWE), and other were calculated and compared with invasively-measured LV SWI. Results: The population included 44 patients. Median time between RHC and echocardiography was 0 days (IQR: 0-24). Median age was 60 years (IQR: 54-63). For the most part, etiology of HF was non-ischemic (61.4%) and all patients were either on class NYHA II (61.4%) or III (27.3%). Median left ventricular ejection fraction was 25% (IQR: 22.3-32.3), median NT-proBNP 1,377 pg/ml (IQR: 646-2570). LV global longitudinal strain (GLS) significantly correlated with LV SWI (r = -0.337; p = 0.031), whereas, LV ejection fraction (EF) did not (r = 0.308; p = 0.050). With regard to LV MW indices, some of them demonstrated correlation with LV SWI, particularly LV GWI (r = 0.425; p = 0.006), LV GCW (r = 0.506; p = 0.001), LV global positive work (LV GPW; r = 0.464; p = 0.003) and LV global systolic constructive work (GSCW; r = 0.471; p = 0.002). Conclusion: Among LV MW indices, LV GCW correlated better with invasively-derived SWI, potentially representing a powerful tool for a more comprehensive evaluation of myocardial function.
ABSTRACT
AIMS: The aim of this study was to minimize the procedure, and reduce the length of hospital stay (LoS) is the future objective for transcatheter aortic valve replacement (TAVI).Aims of the study are to identify procedural and electrocardiographical predictors of fast-track discharge in patients who underwent TAVI. METHODS: Patients treated with TAVI included in the One Hospital ClinicalService project were categorized according to the LoS. 'Fast-Track' population, with a postprocedural LoS less than or equal to 3âdays, was compared with the 'Slow-Track' population with a postprocedural LoS greater than 3âdays. RESULTS: One thousand five hundred and one patients were collected. Despite single baseline characteristics being almost similar between the two groups, Slow-Track group showed a higher surgical risk (Pâ<â0.001). Patients in the Slow-Track group were more frequently treated with general anaesthesia (Pâ=â0.002) and less frequently predilated (Pâ<â0.001) and received a lower amount of contrast media. No difference between Slow-Track and Fast-Track patients was observed at 30 days in death and in cardiovascular rehospitalization.In the multivariable analysis, STS score of at least 4% [odds ratio (OR): 1.64; Pâ=â0.01], general anaesthesia (OR: 2.80; Pâ=â0.03), predilation (OR: 0.45; Pâ<â001), NYHA 3-4 at baseline (OR: 1.65; Pâ=â0.01), AVB I/LBBB/RBBB onset (OR: 2.41; Pâ<â0.001) and in-hospital new PM (OR: 2.63; Pâ<â0.001) were independently associated with a higher probability of Slow-Track. CONCLUSION: Fast-Track patients were safely discharged home showing no difference in clinical outcomes after discharge up to 30âdays compared with the Slow-Track group. The STS score, general anaesthesia, NYHA 3--4 at baseline, in-hospital onset of conduction disturbances and new PM implantation after TAVI turned out to be predictors of Slow-Track.

OBJECTIVES: We evaluated the acute and two-year safety and efficacy of using the Corevalve, Evolut R, and Evolut PRO valves for treating failed surgical bioprosthesis from the Italian CoreValve Clinical Service Project. BACKGROUND: Valve-in-valve (ViV) TAVR is an emerging treatment option for failed surgical bioprosthesis. Choice of transcatheter valve is an important determinant of procedural and clinical outcomes, however, longer-term data are lacking. METHODS: The Clinical Service Project is a national clinical data repository evaluating the use of implantable devices across Italy. The present multi-center analysis includes consecutive patients who underwent ViV-TAVR with the Medtronic CoreValve series between October 2008 to June 2019. Evaluated endpoints included rates of overall mortality, cardiovascular mortality, myocardial infarction, and cerebrovascular accidents at 2-year follow-up. Procedural success, complications, and echocardiographic outcomes were reported according to VARC-2 criteria. RESULTS: A total of 139 patients (mean age, 80 ± 7 years; 47.5% male; mean STS score, 10.0 ± 9.7%) underwent ViV-TAVR with CoreValve (28.5%), Evolut R (68.6%), and Evolut Pro (2.9%) valves. Device success was achieved in 68% and acute coronary obstruction requiring PCI was observed in 4 patients (2.9%). Moderate PVL was observed in 3.7% and 2.8% of patients at 30-day and 2-year follow-up and moderate structural valve degeneration seen only 5 patients (3.6%). All-cause and cardiovascular mortality were 3.6% and 2.9% at 30 days, respectively, and 20.6% and 10.2% at 2-year follow-up. CONCLUSIONS: This real-world nationwide analysis demonstrates the acute and longer-term safety and efficacy of using the self-expanding Medtronic THV for ViV-TAVR.

Although most patients with small aortic annulus are women, there is paucity of data on the prognostic impact of small aortic prosthesis in women who underwent transcatheter aortic valve implantation (TAVI). Therefore, we aimed to evaluate the impact of small valve size on 1-year clinical outcomes after TAVI in women. The Women's INternational Transcatheter Aortic Valve Implantation is an all-women registry evaluating patients with severe aortic stenosis who underwent TAVI. Based on the size of the aortic bioprosthesis implanted, women were stratified into small (≤23 mm) and nonsmall (>23 mm) valve. The primary efficacy endpoint was the Valve Academic Research Consortium-2 composite of all-cause death, stroke, myocardial infarction, hospitalization for valve-related symptoms or heart failure or valve-related dysfunction at 1-year follow-up. Of 934 women who underwent TAVI, 388 (41.5%) received a small valve. Women with a small valve size had a lower body mass index, lower surgical risk scores, were less likely to suffer from atrial fibrillation, less often required postdilation and had a lower rate of residual aortic regurgitation grade ≥2. The occurrence of the Valve Academic Research Consortium-2 efficacy endpoint was similar between women treated with small and nonsmall valve (16.0% vs 16.3%, p = 0.881; adjusted hazard ratio 1.34, 95% confidence interval 0.90 to 2.00). Likewise, there were no significant differences in the occurrence of other secondary endpoints after multivariable adjustment. In conclusion, women with severe aortic stenosis who underwent TAVI with the implantation of a small valve bioprosthesis had similar 1-year outcomes as those receiving a nonsmall bioprosthesis.
