RESUMEN
BACKGROUND AND AIMS: Older patients with non-ST-elevation acute coronary syndrome (NSTEACS) are less likely to receive guideline-recommended care including coronary angiography and revascularization. Evidence-based recommendations regarding interventional management strategies in this patient cohort are scarce. This meta-analysis aimed to assess the impact of routine invasive vs. conservative management of NSTEACS by using individual patient data (IPD) from all available randomized controlled trials (RCTs) including older patients. METHODS: MEDLINE, Web of Science and Scopus were searched between 1 January 2010 and 11 September 2023. RCTs investigating routine invasive and conservative strategies in persons >70 years old with NSTEACS were included. Observational studies or trials involving populations outside the target range were excluded. The primary endpoint was a composite of all-cause mortality and myocardial infarction (MI) at 1 year. One-stage IPD meta-analyses were adopted by use of random-effects and fixed-effect Cox models. This meta-analysis is registered with PROSPERO (CRD42023379819). RESULTS: Six eligible studies were identified including 1479 participants. The primary endpoint occurred in 181 of 736 (24.5%) participants in the invasive management group compared with 215 of 743 (28.9%) participants in the conservative management group with a hazard ratio (HR) from random-effects model of 0.87 (95% CI 0.63-1.22; P = .43). The hazard for MI at 1 year was significantly lower in the invasive group compared with the conservative group (HR from random-effects model 0.62, 95% CI 0.44-0.87; P = .006). Similar results were seen for urgent revascularization (HR from random-effects model 0.41, 95% CI 0.18-0.95; P = .037). There was no significant difference in mortality. CONCLUSIONS: No evidence was found that routine invasive treatment for NSTEACS in older patients reduces the risk of a composite of all-cause mortality and MI within 1 year compared with conservative management. However, there is convincing evidence that invasive treatment significantly lowers the risk of repeat MI or urgent revascularisation. Further evidence is needed from ongoing larger clinical trials.

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.
RESUMEN
Transcatheter aortic valve implantation (TAVI) with commissural alignment aims to limit the risk of coronary occlusion and maintain good coronary access. However, due to coronary origin eccentricity within the coronary cusp, coronary-commissural overlap (CCO) may still occur. TAVI using coronary alignment, rather than commissural alignment, may further improve coronary access. To compare rates of CCO after TAVI using commissural versus coronary alignment methodology. Cardiac CT scans from 102 patients with severe (tricuspid) aortic stenosis referred for TAVI were analysed. Native cusp asymmetry and coronary eccentricity were defined and used to simulate TAVI using commissural versus coronary alignment. Rates of optimal coronary alignment (< 10° from cusp centre) and severe misalignment (< 15° from coronary-commissural overlap) were compared. Additionally, the impact of valve misalignment during implantation was assessed. The native right coronary artery (RCA) origin was 15.8° (9.5 to 24°) closer to the right coronary cusp/non-coronary cusp (RCC-NCC) commissure than the centre of the right coronary cusp. The native left coronary artery (LCA) origin was 4.5° (0 to 11.5°) closer to the left coronary cusp/non-coronary cusp (LCC-NCC) commissure than the centre of the left coronary cusp (p < 0.01). Compared to commissural alignment, coronary alignment doubled the proportion of optimally-aligned RCAs (62/102 [60.8%] vs. 31/102 [30.4%]; p < 0.001), without a significant change in optimal LCA alignment (62/102 [60.8% vs. 74/102 [72.6%]; p = 0.07). There were no cases of severe misalignment with either strategy. Simulating 15° of valve misalignment resulted in severe RCA compromise risk in 7/102 (6.9%) of commissural alignment cases, compared to none using coronary alignment. Fluoroscopic projection was similar with both approaches. Coronary alignment resulted in a 2-fold increase of optimal TAVI positioning relative to the RCA ostium when compared to commissural alignment without impacting the LCA. Use of coronary alignment rather than commissural alignment may improve coronary access after TAVI and is less sensitive to valve rotational error, particularly for the right coronary artery.

BACKGROUND: In patients with distal bifurcation left main stem lesions requiring intervention, the European Bifurcation Club Left Main Coronary Stent Study trial found a non-significant difference in major adverse cardiac events (MACEs, composite of all-cause death, non-fatal myocardial infarction and target lesion revascularisation) favouring the stepwise provisional strategy, compared with the systematic dual stenting. AIMS: To estimate the 1-year cost-effectiveness of stepwise provisional versus systematic dual stenting strategies. METHODS: Costs in France and the UK, and MACE were calculated in both groups to estimate the incremental cost-effectiveness ratio (ICER). Uncertainty was explored by probabilistic bootstrapping. The analysis was conducted from the perspective of the healthcare provider with a time horizon of 1 year. RESULTS: The cost difference between the two groups was -755 (5700 in the stepwise provisional group and 6455 in the systematic dual stenting group, p value<0.01) in France and -647 (6728 and 7375, respectively, p value=0.08) in the UK. The point estimates for the ICERs found that stepwise provisional strategy was cost saving and improved outcomes with a probabilistic sensitivity analysis confirming dominance with an 80% probability. CONCLUSION: The stepwise provisional strategy at 1 year is dominant compared with the systematic dual stenting strategy on both economic and clinical outcomes.

Percutaneous left atrial appendage occlusion aims to reduce the risk of stroke in patients with AF, particularly those who are not good candidates for systemic anticoagulation. The procedure has been studied in large international randomised trials and registries and was approved by the National Institute for Health and Care Excellence in 2014 and by NHS England in 2018. This position statement summarises the evidence for left atrial appendage occlusion and presents the current indications. The options and consensus on best practice for pre-procedure planning, undertaking a safe and effective implant and appropriate post-procedure management and follow-up are described. Standards regarding procedure volume for implant centres and physicians, the role of multidisciplinary teams and audits are highlighted.

RESUMEN
BACKGROUND: Incomplete revascularization (ICR) has been associated with a worse prognosis after a percutaneous coronary intervention (PCI). In NSTEMI patients with multivessel disease (MVD) however, the benefit of a complete revascularization (CR) remains unclear. METHODS: Patients presenting with an NSTEMI and MVD were selected from the global e-ULTIMASTER registry and grouped according to completeness of revascularization at index hospitalization discharge. The primary endpoint was the patient oriented composite endpoint (POCE) defined as all death, any myocardial infarction, and any revascularization at 1 year. Target lesion failure (TLF) was defined as the composite of cardiac death, target vessel related myocardial infarction and clinically driven target lesion revascularization. Inverse propensity score weighting (IPSW) was performed to harmonize the patient's baseline characteristics between the groups. RESULTS: CR was achieved in 1800 patients (47.0 %) and ICR in 2032 patients (53.0 %). The incidence of POCE at 1 year was lower in the CR group compared to the ICR group: 7.0 % vs. 12.9 %, p < 0.0001. Similarly for TLF at 1 year: 3.6 % vs. 5.5 %, p < 0.01. After IPSW, the incidence of POCE was 7.7 % vs. 12.0 %, p < 0.0001, due to a lower all-cause mortality: 2.7 % vs. 4.2 %, p = 0.02 and less revascularizations: 4.9 % vs. 7.9 %, p < 0.001. The incidence of TLF was no longer statistically significant: CR 3.9 % vs. IR 5.0 %, p = 0.10. CONCLUSIONS: Patients with a NSTEMI and multi vessel disease undergoing a percutaneous coronary revascularization with a complete revascularization during index hospitalization have better 1-year clinical outcomes. Randomized studies are warranted to confirm these results.
RESUMEN
BACKGROUND: Transcatheter aortic valve implantation (TAVI) serves a growing range of patients with severe aortic stenosis (AS). TAVI has evolved to a streamlined procedure minimizing length of hospital stay. AIMS: To evaluate the safety and efficacy of an early discharge (ED) strategy after TAVI. METHODS: We performed an international, multi-center, prospective observational single-arm study in AS patients undergoing TAVI with the ACURATE valve platform. Eligibility for ED was assessed prior to TAVI and based on prespecified selection criteria. Discharge ≤ 48 h was defined as ED. Primary Valve Academic Research Consortium (VARC)-3-defined 30-day safety and efficacy composite endpoints were landmarked at 48 h and compared between ED and non-ED groups. RESULTS: A total of 252 patients were included. The median age was 82 [25th-75th percentile, 78-85] years and the median Society of Thoracic Surgeons Predicted Risk of Mortality (STS-PROM) score was 2.2% [25th-75th percentile, 1.6-3.3]. ED and non-ED were achieved in 173 (69%) and 79 (31%) patients respectively. Monitoring for conduction disturbances was the principal reason for non-ED (33%). Overall, at 30 days, all-cause mortality was 1%, new permanent pacemaker rate was 4%, and valve- or procedure-related rehospitalization was 4%. There was no difference in the primary safety and efficacy endpoint between the ED and non-ED cohorts (OR 0.84 [25th-75th percentile, 0.31-2.26], p = 0.73, and OR 0.97 [25th-75th percentile, 0.46-2.06], p = 0.94). The need for rehospitalization was similarly low for ED and non-ED groups. CONCLUSION: Early discharge after TAVI with the ACURATE valve is safe and feasible in selected patients. Rhythm monitoring and extended clinical observation protracted hospital stay.
RESUMEN
The 2023 European Bifurcation Club (EBC) meeting took place in Warsaw in October, and the latest evidence for the use of intravascular ultrasound (IVUS) and optical coherence tomography (OCT) to optimise percutaneous coronary interventions (PCI) on coronary bifurcation lesions (CBLs) was a major focus. The topic generated deep discussions and general appraisal on the potential benefits of IVUS and OCT in PCI procedures. Nevertheless, despite an increasing recognition of IVUS and OCT capabilities and their recognised central role for guidance in complex CBL and left main PCI, it is expected that angiography will continue to be the primary guidance modality for CBL PCI, principally due to educational and economic barriers. Mindful of the restricted access/adoption of intracoronary imaging for CBL PCI, the EBC board decided to review and describe a series of tips and tricks which can help to optimise angiography-guided PCI for CBLs. The identified key points for achieving an optimal angiography-guided PCI include a thorough analysis of pre-PCI images (computed tomography angiography, multiple angiographic views, quantitative coronary angiography vessel estimation), a systematic application of the technical steps suggested for a given selected technique, an intraprocedural or post-PCI use of stent enhancement and a low threshold for bailout use of intravascular imaging.

BACKGROUND: Acute ischemic stroke remains a serious complication of transcatheter aortic valve replacement (TAVR). Cerebral embolic protection devices (CEPD) were developed to mitigate the risk of acute ischemic stroke complicating TAVR (AISCT). However, the existing body of evidence does not clearly support CEPD efficacy in AISCT prevention. OBJECTIVES: In a cohort of patients with AISCT, we aimed to compare the characteristics and outcomes of patients who have had unprotected TAVR (CEPD-) vs CEPD-protected TAVR (CEPD+). METHODS: Data were derived from an international multicenter registry focusing on AISCT. We included all patients who experienced ischemic stroke within 72 hours of TAVR. Stroke severity was assessed using the National Institutes of Health Stroke Scale (NIHSS). Primary outcomes were neurologic disability status according to the modified Rankin Score at 30 days, and 6-month all-cause death. Propensity score matched analysis was used to control for differences between groups. RESULTS: In 18,725 TAVR procedures, 416 AISCT (2.2%) within 72 hours were documented, of which 376 were in the CEPD- TAVR group and 40 in the CEPD+ TAVR group. Although the middle cerebral artery stroke rate was similar in both groups (29.7% CEPD- vs 33.3% CEPD+; P = 0.71), AISCT in the CEPD+ group was characterized by a lower rate of internal carotid artery occlusion (0% vs 4.7%) and higher rate of vertebrobasilar system strokes (15.4% vs 5.7%; P = 0.04). AISCT was severe (NIHSS ≥15) in 21.6% CEPD- and 23.3% CEPD+ AISCT (P = 0.20). Disabling stroke rates (modified Rankin Score >1 at 30 days) were 47.3% vs 42.5% (P = 0.62), and 6-month mortality was 31.3% vs 23.3% (P = 0.61), in the CEPD- and CEPD+ groups, respectively. In the propensity score matched cohort, disabling stroke rates were 56.5% vs 41.6% (P = 0.16), and 6-month mortality was 33% vs 19.5% (P = 0.35), in the CEPD- and CEPD+ groups, respectively. CONCLUSIONS: In a large cohort of patients with AISCT, the use of CEPD had little effect on stroke distribution, severity, and outcomes.

BACKGROUND: Dialysis is a rare but serious complication after transcatheter aortic valve replacement. We analyzed the large multicenter TRITAVI (transfusion requirements in transcatheter aortic valve implantation) registry in order to develop and validate a clinical score assessing this risk. METHODS AND RESULTS: A total of 10 071 consecutive patients were enrolled in 19 European centers. Patients were randomly assigned (2:1) to a derivation and validation cohort. Two scores were developed, 1 including only preprocedural variables (TRITAVIpre) and 1 also including procedural variables (TRITAVIpost). In the 6714 patients of the derivation cohort (age 82±6 years, 48% men), preprocedural factors independently associated with dialysis and included in the TRITAVIpre score were male sex, diabetes, prior coronary artery bypass graft, anemia, nonfemoral access, and creatinine clearance <30 mL/min per m2. Additional independent predictors among procedural features were volume of contrast, need for transfusion, and major vascular complications. Both scores showed a good discrimination power for identifying risk for dialysis with C-statistic 0.78 for TRITAVIpre and C-statistic 0.88 for TRITAVIpost score. Need for dialysis increased from the lowest to the highest of 3 risk score groups (from 0.3% to 3.9% for TRITAVIpre score and from 0.1% to 6.2% for TRITAVIpost score). Analysis of the 3357 patients of the validation cohort (age 82±7 years, 48% men) confirmed the good discrimination power of both scores (C-statistic 0.80 for TRITAVIpre and 0.81 for TRITAVIpost score). Need for dialysis was associated with a significant increase in 1-year mortality (from 6.9% to 54.4%; P=0.0001). CONCLUSIONS: A simple preprocedural clinical score can help predict the risk of dialysis after transcatheter aortic valve replacement.

BACKGROUND: The COVID-19 pandemic adversely affected health care systems. Patients in need of transcatheter aortic valve replacement (TAVR) are especially susceptible to treatment delays. OBJECTIVES: This study sought to evaluate the impact of the COVID-19 pandemic on global TAVR activity. METHODS: This international registry reported monthly TAVR case volume in participating institutions prior to and during the COVID-19 pandemic (January 2018 to December 2021). Hospital-level information on public vs private, urban vs rural, and TAVR volume was collected, as was country-level information on socioeconomic status, COVID-19 incidence, and governmental public health responses. RESULTS: We included 130 centers from 61 countries, including 65,980 TAVR procedures. The first and second pandemic waves were associated with a significant reduction of 15% (P < 0.001) and 7% (P < 0.001) in monthly TAVR case volume, respectively, compared with the prepandemic period. The third pandemic wave was not associated with reduced TAVR activity. A greater reduction in TAVR activity was observed in Africa (-52%; P = 0.001), Central-South America (-33%; P < 0.001), and Asia (-29%; P < 0.001). Private hospitals (P = 0.005), urban areas (P = 0.011), low-volume centers (P = 0.002), countries with lower development (P < 0.001) and economic status (P < 0.001), higher COVID-19 incidence (P < 0.001), and more stringent public health restrictions (P < 0.001) experienced a greater reduction in TAVR activity. CONCLUSIONS: TAVR procedural volume declined substantially during the first and second waves of the COVID-19 pandemic, especially in Africa, Central-South America, and Asia. National socioeconomic status, COVID-19 incidence, and public health responses were associated with treatment delays. This information should inform public health policy in case of future global health crises.

Background: While female sex has been associated with worse outcomes following coronary revascularization, previous analyses in left main coronary artery (LMCA) disease have been conflicting. In addition, a signal that increased mortality may be specific to women treated with percutaneous coronary intervention (PCI) requires further investigation. Methods: Nordic-Baltic-British left main revascularization study (NOBLE) was a randomized trial comparing PCI to coronary artery bypass surgery (CABG) in patients with LMCA disease. The primary endpoint was a composite of all-cause mortality, nonprocedural myocardial infarction, repeat revascularization, and stroke (major adverse cardiovascular and cerebrovascular events [MACCE]). We report the 5-year sex-specific outcomes. Results: Of 1184 patients analyzed, 256 (22%) were female and 928 (78%) were male. There were no significant within-sex differences in baseline characteristics, disease location, or complexity between those treated with PCI and those with CABG. The 5-year MACCE rates were 29% and 15% in females and 28% and 20% in males treated with PCI and CABG, respectively. Within both sexes, there was an increased risk of MACCE with PCI compared with CABG, but no difference in all-cause mortality. On multivariate analysis, female sex was not an independent predictor of MACCE. Conclusions: Following the treatment of LMCA disease, long-term outcomes favored CABG over PCI in both sexes. Importantly, there was no difference in all-cause mortality in females or males at 5 âyears.
RESUMEN
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: 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.

Safety and feasibility of transfemoral Acurate neo implantation without systematic predilatation are not fully investigated. Our aim was to evaluate the use and impact of pre-implantation balloon aortic valvuloplasty (pre-BAV) before transcatheter aortic valve implantation (TAVI) with Acurate neo. The NEOPRO Registry retrospectively included 1,263 patients who underwent transfemoral TAVI with Acurate neo at 18 centers between January 2012 and March 2018. Information on preBAV was available for 1,262 patients (99.9%). Primary endpoints were pre-discharge moderate-tosevere paravalvular aortic regurgitation (PAR II+), 30-day new permanent pacemaker implantation (PPI), and 30-day all-cause mortality or stroke. A total of 1,262 patients who underwent TAVI with (n=1,051) or without predilatation (n=211) were included. A reduction in the pre-BAV rate was observed during the study period (from 95.7% in the first date quintile to 78.4% in the last date quintile). Patients who underwent pre-BAV had higher degrees of aortic valve (AV) and left ventricular outflow tract (LVOT) calcification. Primary endpoints were similar between pre-BAV and no pre-BAV groups (PAR II+ 5.5% vs. 3.4%, p=0.214; 30-day PPI 9.0% vs. 8.0%, p=0.660; 30-day death or stroke 4.9% vs. 4.4%, p=0.743). The need for postdilatation and other procedural outcomes were comparable between groups. Predilatation did not have a significant impact on primary endpoints across AV and LVOT calcification subgroups (subgroup analyses) and was not independently associated with primary endpoints (multivariate analyses). In conclusion, transfemoral Acurate neo implantation without predilatation appears to be feasible and safe, especially in patients with milder degrees of AV and LVOT calcification. (AU)

Abstract OBJECTIVES: The aim of this study was to compare transcatheter aortic valve replacement (TAVR) with the Acurate neo (NEO) and Evolut PRO (PRO) devices. BACKGROUND: The NEO and PRO bioprostheses are 2 next-generation self-expanding devices developed for TAVR. METHODS: The NEOPRO (A Multicenter Comparison of Acurate NEO Versus Evolut PRO Transcatheter Heart Valves) registry retrospectively included patients who underwent transfemoral TAVR with either NEO or PRO valves at 24 centers between January 2012 and March 2018. One-to-one propensity score matching resulted in 251 pairs. Pre-discharge and 30-day Valve Academic Research Consortium (VARC)-2 defined outcomes were evaluated. Binary logistic regression was performed to adjust the treatment effect for propensity score quintiles. RESULTS: A total of 1,551 patients (n = 1,263 NEO; n = 288 PRO) were included. The mean age was 82 years, and the mean Society of Thoracic Surgeons score was 5.1%. After propensity score matching (n = 502), VARC-2 device success (90.6% vs. 91.6%; p = 0.751) and pre-discharge moderate to severe (II+) paravalvular aortic regurgitation (7.3% vs. 5.7%; p = 0.584) were comparable between the NEO and PRO groups. Furthermore, there were no significant differences in any 30-day clinical outcome between matched NEO and PRO pairs, including all-cause mortality (3.2% vs. 1.2%; p = 0.221), stroke (2.4% vs. 2.8%; p = 1.000), new permanent pacemaker implantation (11.0% vs. 12.8%; p = 0.565), and VARC-2 early safety endpoint (10.6% vs. 10.4%; p = 1.000). Logistic regression on the unmatched cohort confirmed a similar risk of VARC-2 device success, paravalvular aortic regurgitation II+, and 30-day clinical outcomes after NEO and PRO implantation.
