Impact of untreated chronic obstructive coronary artery disease on outcomes after transcatheter aortic valve replacement. Eur Heart J 2024; 45:1890-1900. [PMID: 38270189 DOI: 10.1093/eurheartj/ehae019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/02/2023] [Revised: 11/24/2023] [Accepted: 01/09/2024] [Indexed: 01/26/2024] Open
Abstract
BACKGROUND AND AIMS In transcatheter aortic valve replacement (TAVR) recipients, the optimal management of concomitant chronic obstructive coronary artery disease (CAD) remains unknown. Some advocate for pre-TAVR percutaneous coronary intervention, while others manage it expectantly. The aim of this study was to assess the impact of varying degrees and extent of untreated chronic obstructive CAD on TAVR and longer-term outcomes. METHODS The authors conducted a retrospective cohort study of TAVR recipients from January 2015 to November 2021, separating patients into stable non-obstructive or varying degrees of obstructive CAD. The major outcomes of interest were procedural all-cause mortality and complications, major adverse cardiovascular events, and post-TAVR unplanned coronary revascularization. RESULTS Of the 1911 patients meeting inclusion, 75%, 6%, 10%, and 9% had non-obstructive, intermediate-risk, high-risk, and extreme-risk CAD, respectively. Procedural complication rates overall were low (death 0.4%, shock 0.1%, extracorporeal membrane oxygenation 0.1%), with no difference across groups. At a median follow-up of 21 months, rates of acute coronary syndrome and unplanned coronary revascularization were 0.7% and 0.5%, respectively, in the non-obstructive population, rising in incidence with increasing severity of CAD (P < .001 for acute coronary syndrome/unplanned coronary revascularization). Multivariable analysis did not yield a significantly greater risk of all-cause mortality or major adverse cardiovascular events across groups. One-year acute coronary syndrome and unplanned coronary revascularization rates in time-to-event analyses were significantly greater in the non-obstructive (98%) vs. obstructive (94%) subsets (Plog-rank< .001). CONCLUSIONS Transcatheter aortic valve replacement can be performed safely in patients with untreated chronic obstructive CAD, without portending higher procedural complication rates and with relatively low rates of unplanned coronary revascularization and acute coronary syndrome at 1 year.

Abstract
B-lymphocytes play major adaptive immune roles, producing antibody and driving T-cell responses. However, how immunometabolism networks support B-cell activation and differentiation in response to distinct receptor stimuli remains incompletely understood. To gain insights, we systematically investigated acute primary human B-cell transcriptional, translational and metabolomic responses to B-cell receptor (BCR), Toll-like receptor 9 (TLR9), CD40-ligand (CD40L), interleukin-4 (IL4) or combinations thereof. T-independent BCR/TLR9 co-stimulation, which drives malignant and autoimmune B-cell states, jointly induced PD-L1 plasma membrane expression, supported by NAD metabolism and oxidative phosphorylation. BCR/TLR9 also highly induced the transaminase BCAT1, which localized to lysosomal membranes to support branched chain amino acid synthesis and mTORC1 hyperactivation. BCAT1 inhibition blunted BCR/TLR9, but not CD40L/IL4-triggered B-cell proliferation, IL10 expression and BCR/TLR pathway-driven lymphoma xenograft outgrowth. These results provide a valuable resource, reveal receptor-mediated immunometabolism remodeling to support key B-cell phenotypes including PD-L1 checkpoint signaling, and identify BCAT1 as a novel B-cell therapeutic target.

Abstract
BACKGROUND The aims of this study were to understand the incidence and outcomes of patients with cardiogenic shock (CS) due to severe aortic stenosis (AS), and the impact of conventional treatment strategies in this population. METHODS AND RESULTS All patients admitted to the Cleveland Clinic cardiac intensive care unit between January 1, 2010 and December 31, 2021 with CS were retrospectively identified and categorized into those with CS in the setting of severe AS versus CS without AS. The impact of various treatment strategies on mortality was further assessed. We identified 2754 patients with CS during the study period, of whom 216 patients (8%) had CS in the setting of severe AS. Medical management was associated with the highest 30-day mortality when compared with either balloon aortic valve replacement or aortic valve replacement (surgical or transcatheter aortic valve replacement) (hazard ratio, 3.69 [95% CI, 2.04-6.66]; P<0.0001). Among patients who received transcatheter therapy, 30-day mortality was significantly higher in patients who received balloon aortic valvuloplasty versus transcatheter aortic valve replacement (26% versus 4%, P=0.02). Both surgical and transcatheter aortic valve replacement had considerably lower mortality than medical management and balloon aortic valvuloplasty at 30 days and 1 year (P<0.05 for both comparisons). CONCLUSIONS CS due to severe AS is associated with high in-hospital and 30-day mortality, worse compared with those with CS without AS. In suitable patients, urgent surgical aortic valvuloplasty or transcatheter aortic valve replacement is associated with favorable short- and long-term outcomes. Although balloon aortic valvuloplasty may be used to temporize patients with CS in the setting of severe AS, mortality is ≈50% if not followed by definitive aortic valve replacement within 90 days.

Abstract
OBJECTIVE Patients with moderate aortic stenosis (AS) exhibit high morbidity and mortality. Limited evidence exists on the role of aortic valve replacement (AVR) in this patient population. To investigate the benefit of AVR in moderate AS on survival and left ventricular function. METHODS In a retrospective cohort study, patients with moderate AS between 2008 and 2016 were selected from the Cleveland Clinic echocardiography database and followed until 2018. Patients were classified as receiving AVR or managed medically (clinical surveillance). All-cause and cardiovascular mortality were assessed by survival analyses. Temporal haemodynamic and structural changes were assessed with longitudinal analyses using linear mixed effects models. RESULTS We included 1421 patients (mean age, 75.3±5.4 years and 39.9% women) followed over a median duration of 6 years. Patients in the AVR group had lower risk of all-cause (adjusted HR (aHR)=0.51, 95% CI: 0.34 to 0.77; p=0.001) and cardiovascular mortality (aHR=0.50, 95% CI: 0.31 to 0.80; p=0.004) compared with those in the clinical surveillance group irrespective of sex, receipt of other open-heart surgeries and underlying malignancy. These findings were seen only in those with preserved left ventricular ejection fraction (LVEF) ≥50%. Further, patients in the AVR group had a significant trend towards an increase in LVEF and a decrease in right ventricular systolic pressure compared with those in the clinical surveillance group. CONCLUSIONS In patients with moderate AS, AVR was associated with favourable clinical outcomes and left ventricular remodelling.

Abstract
BACKGROUND Permanent pacemaker implantation (PPI) rates following transcatheter aortic valve replacement (TAVR) remain a concern. We assessed the PPI rates over time in patients implanted with an Evolut supra-annular, self-expanding transcatheter valve from the US STS/ACC TVT Registry. METHODS Patients who underwent TAVR with an Evolut R, Evolut PRO or Evolut PRO+ valve between July 2018 (Q3) and June 2021 (Q2) were included. PPI rates were reported by calendar quarter. In-hospital PPI rates were reported as proportions and 30-day rates as Kaplan-Meier estimates. A Cox regression model was used to determine potential predictors of a new PPI within 30 days of the TAVR procedure. RESULTS From July 2018 to June 2021, 54,014 TAVR procedures were performed using Evolut valves. Mean age was 79.3 ± 8.8 years and 49.2 % were male. The 30-day PPI rate was 16.6 % in 2018 (Q3) and 10.8 % in 2021 (Q2, 34.9 % decrease, p < 0.001 for trend across all quarters). The in-hospital PPI rate decreased by 40.1 %; from 14.7 % in 2018 (Q3) to 8.8 % in 2021 (Q2) (p < 0.001 for trend across all quarters). Significant predictors of a new PPI within 30 days included a baseline conduction defect, history of atrial fibrillation, home oxygen, and diabetes mellitus. CONCLUSION From 2018 to 2021, TAVR with an Evolut transcatheter heart valve in over 50,000 patients showed a significant decreasing trend in the rates of in-hospital and 30-day PPI, representing the lowest rate of PPI in any large real-world registry of Evolut. During the same evaluated period, high device success and shorter length of stay was also observed.

Abstract
Oral tumors are relatively common in dogs, and canine oral squamous cell carcinoma (COSCC) is the most prevalent oral malignancy of epithelial origin. COSCC is locally aggressive with up to 20% of patients showing regional or distant metastasis at the time of diagnosis. The treatment of choice most typically involves wide surgical excision. Although long-term remission is possible, treatments are associated with significant morbidity and can negatively impact functionality and quality of life. OSCCs have significant upregulation of the RAS-RAF-MEK-MAPK signaling axis, and we had previously hypothesized that small-molecule inhibitors that target RAS signaling might effectively inhibit tumor growth and progression. Here, we demonstrate that the MEK inhibitor trametinib, an FDA-approved drug for human cancers, significantly blocks the growth of several COSCC cell lines established from current patient tumor samples. We further show clinical evidence that the drug is able to cause significant tumor regression in some patients with spontaneously occurring COSCC. Given the limited treatment options available and the high rate of owner rejection of these offered options, these findings provide new hope that more acceptable treatment options may soon enter the veterinary clinic.

Abstract
Low muscle mass (LMM) is associated with worse outcomes in various clinical situations. Traditional frailty markers have been used for preoperative risk stratification in patients who underwent transcatheter aortic valve replacement (TAVR). However, preoperative imaging provides an opportunity to directly quantify skeletal muscle mass to identify patients at higher risk of procedural complications. We reviewed all TAVR recipients from January to December 2018 and included subjects with preprocedural chest computed tomography. Multi-slice automated measurements of skeletal muscle mass were made from the ninth to twelfth thoracic vertebrae and normalized by height squared to obtain skeletal muscle index (cm2/m2). LMM was defined as the lowest gender-stratified skeletal muscle index tertile. Strength testing was collected during pre-TAVR evaluation. Primary outcome was a composite of perioperative complications, 1-year rehospitalization, or 1-year mortality. In our cohort, 238 patients met inclusion criteria, and 80 (33.6%) were identified to have LMM. Patients with LMM were older with lower body mass index, decreased grip strength, lower hemoglobin A1c, and higher N-terminal pro-brain natriuretic peptide. They had greater rates of the composite outcome and 2-year all-cause mortality, which remained significant on multivariable adjustment (hazard ratio 1.71, 95% confidence interval 1.05 to 2.78, p = 0.030 and hazard ratio 2.31, 95% confidence interval 1.02 to 5.24, p = 0.045, respectively) compared with patients without LMM; there was no significant difference in 5-year all-cause mortality. In conclusion, LMM was associated with an increase in the primary composite outcome and 2-year all-cause mortality in TAVR recipients. Using automatic muscle processing software on pre-TAVR computed tomography scans may serve as an additional preoperative risk stratification tool.

Abstract
BACKGROUND Candidates for transcatheter aortic valve replacement (TAVR) occasionally have a "borderline-size" aortic annulus between 2 transcatheter heart valve sizes, based on the manufacturer's sizing chart. Data on TAVR outcomes in such patients are limited. METHODS We retrospectively reviewed 1816 patients who underwent transfemoral-TAVR with balloon-expandable valve (BEV) at our institution between 2016 and 2020. We divided patients into borderline and non-borderline groups based on computed tomography-derived annular measurements and compared outcomes. Furthermore, we analyzed procedural characteristics and compared outcomes between the smaller- and larger-valve strategies in patients with borderline-size annulus. RESULTS During a median follow-up of 23.3 months, there was no significant difference between the borderline (n = 310, 17.0 %) and non-borderline (n = 1506) groups in mortality (17.3 % vs. 19.5 %; hazard ratio [HR] = 0.86 [95% CI = 0.62-1.20], p = 0.39), major adverse cardiac/cerebrovascular events (MACCE: death/myocardial infarction/stroke, 21.2 % vs. 21.5 %; HR = 0.97 [0.71-1.32], p = 0.85), paravalvular leak (PVL: mild 21.8 % vs. 20.6 %, p = 0.81; moderate 0 % vs. 1.2 %; p = 0.37), or mean gradient (12.9 ± 5.8 vs. 12.6 ± 5.2 mmHg, p = 0.69) at 1 year. There was no significant difference between the larger-(n = 113) and smaller-valve(n = 197) subgroups in mortality (23.7 % vs. 15.2 %; HR = 1.57 [0.89-2.77], p = 0.12), MACCE (28.1 % vs. 18.4 %; HR = 1.52 [0.91-2.54], p = 0.11), mild PVL (13.3 % vs. 25.9 %; p = 0.12), or mean gradient (12.3 ± 4.5 vs. 13.6 ± 5.3 mmHg, p = 0.16); however, the rate of permanent pacemaker implantation (PPI) was higher in the larger-valve subgroup (15.9 % vs. 2.6 %, p < 0.001). CONCLUSION Borderline-size annulus is not associated with higher risk of adverse outcomes after BEV-TAVR. However, the larger-valve strategy for borderline-size annulus is associated with higher PPI risk, suggesting a greater risk of injury to the conduction system.

Abstract
PURPOSE OF REVIEW The unique pathophysiologic considerations of severe tricuspid regurgitation (TR) have led to advancements in surgical and transcatheter treatments. The purpose of this review is to highlight the current surgical and transcatheter tricuspid valve interventions (TTVI) to functional TR. RECENT FINDINGS Surgical repair with ring annuloplasty consistently demonstrates better outcomes than surgical replacement or other repair approaches. However, surgical uptake of TR correction remains relatively low, and operative mortality rates are still high owing to multiple comorbidities and advanced tricuspid valve disease/right ventricular dysfunction at time of referral. Pivotal trials for tricuspid transcatheter edge-to-edge repair (T-TEER) and transcatheter TV replacement (TTVR) indicate improved quality of life compared to medical therapy alone for high-surgical-risk patients with severe symptomatic TR. Trials are underway to assess caval valve implantation (CAVI), which holds hope for many severe TR patients who are not ideal candidates for T-TEER or orthotopic TTVR. Peri-procedural optimization of right ventricular function remains critical to promote both device success and patient outcomes. SUMMARY Clinical outcomes after surgical TV intervention are poor, often due to intervening late in the disease course of TR. TTVI covers a treatment gap for patients deemed inoperable or high-surgical-risk, but earlier referral for TV interventions is still important prior to patients developing multiorgan dysfunction from chronic untreated TR.

Abstract
BACKGROUND Patients who experience in-hospital ST-segment elevation myocardial infarction (iSTEMI) represent a uniquely high-risk cohort owing to delays in diagnosis, prolonged time to reperfusion and increased mortality. Quality initiatives aimed at improving the care of this vulnerable, yet understudied population are needed. METHODS This study included consecutive patients with iSTEMI treated with percutaneous coronary intervention (PCI) between 1 January 2011 and 15 July 2019 at a single, tertiary referral centre. A comprehensive iSTEMI protocol (CSP) was implemented on 15 July 2014, incorporating: (1) cardiology fellow activation of the catheterisation lab using standardised criteria, (2) nursing chest pain protocol, (3) improved electronic access to electrocardiographic studies, (4) checklist for initial triage and management, (5) 24/7/365 catheterisation lab readiness and (6) radial-first PCI approach. Key metrics and clinical outcomes were compared before and after CSP implementation. RESULTS Among 125 total subjects, the post-CSP cohort (n=81) was younger, had more males and were more likely to be hospitalised for cardiac-related reasons relative to the pre-CSP cohort (n=44) who were more likely hospitalised for operative-related aetiologies. After CSP adoption, median ECG-to-first-device-activation time decreased from 113 min to 64 min (p<0.001), goal ECG-to-first-device-activation time increased from 36% to 76% of patients (p<0.001), administration of guideline-directed medical therapy prior to PCI increased from 27.3% to 65.4% (p<0.001), trans-radial access increased from 16% to 70% (p<0.001) and rates of discharge home increased from 56.8% to 76.5% (p=0.04). Statistically insignificant numerical reductions were observed post-CSP in in-hospital mortality (18.2% vs 9.9%, p=0.30), 30-day mortality (15.9% vs 12.3%, p=0.78) and 1-year mortality (27.3% vs 21.0%, p=0.57). CONCLUSIONS The implementation of a CSP was associated with marked enhancements in key care metrics among patients with iSTEMI. Among a larger cohort, the use of a CSP yielded a significant reduction in ECG-to-first-device-activation time in a particularly vulnerable population at high risk of death.

[PMID: 38069986 DOI: 10.1016/j.jcin.2023.10.043] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/30/2023] [Revised: 10/09/2023] [Accepted: 10/17/2023] [Indexed: 01/12/2024]
Abstract
BACKGROUND Several orthotopic transcatheter strategies have been developed to treat severe tricuspid regurgitation (TR); however, many patients are deemed unsuitable. Caval valve implantation with the TricValve system addresses this unmet need. OBJECTIVES This study sought to determine the impact of TricValve on systemic congestion and quality of life (QOL) at 1 year. METHODS The TRICUS (Safety and Efficacy of the TricValve® Transcatheter Bicaval Valves System in the Superior and Inferior Vena Cava in Patients With Severe Tricuspid Regurgitation) and TRICUS EURO studies were prospective, nonblinded, nonrandomized, single-arm trials representing the early-in-man experience of the TricValve system in NYHA functional class III or IV severe TR patients, optimally medicated and ineligible for open heart surgery, with significant caval backflow. The primary endpoint was QOL metrics and functional status. The 1-year results of the combined cohort are described here. RESULTS Forty-four patients were included. Mean age was 76.2 ± 7.5 years, 81.0% were women, and the TRISCORE (risk score model for isolated tricuspid valve surgery) was 5.3 ± 1.3. Clinical improvement at 1 year was achieved in 42 (95.5%) patients, measured by (at least 1 of) an increase in ≥15 points from baseline in 12-item Kansas City Cardiomyopathy Questionnaire score, improvement to NYHA functional class to I or II, or an increase ≥40 m in the 6-minute walk test. There were 3 (6.8%) deaths at 1-year follow-up (1 cardiovascular), and the heart failure rehospitalization rate was 29.5%. Stent fracture, conduction system disturbances, or clinically significant leaflet thrombosis were not detected. Abolished hepatic vein backflow was achieved and persisted in 63.8% of the patients, contributing towards a reduction in congestive symptoms, N-terminal pro-B-type natriuretic peptide levels (P = 0.032), and diuretic treatment. CONCLUSIONS Caval valve implantation with the TricValve system associated with meaningful 1-year clinical improvements in terms of QOL along with relatively low mortality rates.

Abstract
Bicuspid aortic valve (BAV) is a common congenital valvular malformation, which may lead to early aortic valve disease and bicuspid-associated aortopathy. A novel BAV classification system was recently proposed to coincide with transcatheter aortic valve replacement being increasingly considered in younger patients with symptomatic BAV, with good clinical results, yet without randomized trial evidence. Procedural technique, along with clinical outcomes, have considerably improved in BAV patients compared with tricuspid aortic stenosis patients undergoing transcatheter aortic valve replacement. The present review summarizes the novel BAV classification systems and examines contemporary surgical and transcatheter approaches.

Abstract
BACKGROUND Regional functional left ventricular (LV) assessment using current imaging techniques remains limited. Inward displacement (InD) has been developed as a novel technique to assess regional LV function via measurement of the regional displacement of the LV endocardial border across each of the 17 LV segments. Currently, normal ranges for InD are not available for clinical use. The aim of this study was to validate the normal reference limits of InD in healthy adults across all LV segments. METHODS InD was analyzed in 120 healthy subjects with a normal LV ejection fraction, using the three standard long-axis views obtained during cardiac MRI that quantified the degree of inward endocardial wall motion towards the true LV center of contraction. For all LV segments, InD was measured in mm and expressed as a percentage of the theoretical degree of maximal segment contraction towards the true LV centerline. The arithmetic average InD was obtained for each of the 17 segments. The LV was divided into three regions, obtaining average InD at the LV base (segments 1-6), mid-cavity (segments 7-12) and apex (segments 13-17). RESULTS Average InD was 33.4 ± 4.3%. InD was higher in basal and mid-cavity LV segments (32.8 ± 4.1% and 38.1 ± 5.8%) compared to apical LV segments (28.6 ± 7.7%). Interobserver variability correlations for InD were strong (R = 0.80, p < 0.0001). CONCLUSIONS We provide clinically meaningful reference ranges for InD in subjects with normal LV function, which will emerge as an important screening and assessment imaging tool for a range of HFrEF therapies.

MitraCox Score Predicts In-Hospital Mortality in Patients Admitted for Transcatheter Edge-to-Edge Mitral Valve Repair. Am J Cardiol 2023; 207:39-47.

Abstract
As mitral valve transcatheter edge-to-edge repair (M-TEER) is evolving as an effective treatment for high-risk surgical patients with mitral regurgitation, there is a pressing need for cardiologists to optimize resources through risk stratification of in-hospital mortality for this patient population. Although current risk-prediction models have been shown to predict adverse outcomes with reasonable accuracy, models trained using the US nationwide population are lacking. This study aimed to identify clinical, demographic, and procedural features that predict in-hospital mortality, and to derive and validate an in-hospital mortality risk-prediction tool in patients who have undergone M-TEER. A total of 9,373 admissions from the Nationwide Readmissions Database of patients who underwent M-TEER between 2015 and 2018 were used to develop and validate the model. We first performed least absolute shrinkage and selection operator (LASSO) regularization of Cox regression (Coxnet) that is 10-fold cross-validated. The non-zero coefficients were multiplied with the respective values of each observation of the predictors to build the scoring formula. Out of 9,373 admissions, 196 patients (2%) died in-hospital during index admission. In descending order, the top variables that were most predictive of in-hospital mortality were higher age, presence of fluid and electrolyte disturbance, and large metropolitan location of the hospital. The validation C-statistic of the MitraCox score was 0.82. Using X-tile software (Yale School of Medicine, New Haven, Connecticut), 2 cutoffs of the score were determined on the basis of in-hospital mortality and length of stay, and the survival of the population was classified into 3 risk groups: low, intermediate, and high. The scoring system deployed online as a web-based calculator can be accessed at https://kathavs.shinyapps.io/Mitracox_Kapadia/. In conclusion, MitraCox score is easy to calculate and predicts in-hospital mortality depending on length of stay in a dynamic manner.

Abstract
Aims Conduction abnormalities necessitating permanent pacemaker (PPM) implantation remain the most frequent complication post-transcatheter aortic valve implantation (TAVI), yet reliance on PPM function varies. We evaluated the association of right-ventricular (RV)-stimulation rate post-TAVI with 1-year major adverse cardiovascular events (MACE) (all-cause mortality and heart failure hospitalization). Methods and results This retrospective cohort study of patients undergoing TAVI in two high-volume centers included patients with existing PPM pre-TAVI or new PPM post-TAVI. There was a bimodal distribution of RV-stimulation rates stratifying patients into two groups of either low [≤10%: 1.0 (0.0, 3.6)] or high [>10%: 96.0 (54.0, 99.9)] RV-stimulation rate post-TAVI. Hazard ratios (HR) and 95% confidence intervals (CI) were calculated comparing MACE in patients with high vs. low RV-stimulation rates post-TAVI. Of 4659 patients, 408 patients (8.6%) had an existing PPM pre-TAVI and 361 patients (7.7%) underwent PPM implantation post-TAVI. Mean age was 82.3 ± 8.1 years, 39% were women. A high RV-stimulation rate (>10%) development post-TAVI is associated with a two-fold increased risk for MACE [1.97 (1.20, 3.25), P = 0.008]. Valve implantation depth was an independent predictor of high RV-stimulation rate [odds ratio (95% CI): 1.58 (1.21, 2.06), P=<0.001] and itself associated with MACE [1.27 (1.00, 1.59), P = 0.047]. Conclusion Greater RV-stimulation rates post-TAVI correlate with increased 1-year MACE in patients with new PPM post-TAVI or in those with existing PPM but low RV-stimulation rates pre-TAVI. A shallower valve implantation depth reduces the risk of greater RV-stimulation rates post-TAVI, correlating with improved patient outcomes. These data highlight the importance of a meticulous implant technique even in TAVI recipients with pre-existing PPMs.

Abstract
PURPOSE Transthyretin cardiac amyloidosis (ATTR-CA) is thought to be prevalent in patients with severe aortic stenosis (AS) who are referred for transcatheter aortic valve replacement (TAVR). However, prior studies were published when TAVR was only offered to elderly, inoperable, and high-risk patients. The aim of this study was to reevaluate the prevalence of ATTR-CA in a contemporary TAVR population and identify high-risk features to guide referral for technetium-99 pyrophosphate scan (99mTc-PyP scan) screening. METHODS Patients seen in a multidisciplinary TAVR clinic for severe AS 70 years and older were referred for a 99mTc-PyP scan to evaluate for ATTR-CA. The primary outcome was the percent with a positive scan. The discriminatory ability of high-risk features was assessed to develop a more judicious screening system. RESULTS Over the study period, 380 patients underwent screening, and 20 patients (5.3%) had a positive scan, with 17 patients having confirmed ATTR-CA, 1 patient deferring confirmatory testing (combined 4.7%), 1 having light chain amyloidosis, and 1 negative on biopsy. Compared to other patient and echocardiographic measures, elevated NT-pro BNP (> 1000 ng/L) was the best discriminator on who should be referred for 99mTc-PyP scan screening, with a sensitivity of 90% and a negative predictive value of 99%. CONCLUSION The prevalence of ATTR-CA may be lower in a contemporary TAVR population due to its expanded indication for low-risk patients. NT-pro BNP is a simple test that can improve screening yield and more judiciously guide screening for ATTR-CA in this at-risk population. Comparison of the original versus the proposed algorithm.

Abstract
BACKGROUND Coronary accessibility following redo-transcatheter aortic valve replacement (redo-TAVR) is increasingly important, particularly in younger low-risk patients. This study aimed to predict coronary accessibility after simulated Sapien-3 balloon-expandable valve implantation within an Evolut supra-annular, self-expanding valve using pre-TAVR computed tomography (CT) imaging. METHODS A total of 219 pre-TAVR CT scans from the Evolut Low-Risk CT substudy were analyzed. Virtual Evolut and Sapien-3 valves were sized using CT-based diameters. Two initial Evolut implant depths were analyzed, 3 and 5 mm. Coronary accessibility was evaluated for 2 Sapien-3 in Evolut implant positions: Sapien-3 outflow at Evolut node 4 and Evolut node 5. RESULTS With a 3-mm initial Evolut implant depth, suitable coronary access was predicted in 84% of patients with the Sapien-3 outflow at Evolut node 4, and in 31% of cases with the Sapien-3 outflow at Evolut node 5 (P<0.001). Coronary accessibility improved with a 5-mm Evolut implant depth: 97% at node 4 and 65% at node 5 (P<0.001). When comparing 3- to 5-mm Evolut implant depth, sinus sequestration was the lowest with Sapien-3 outflow at Evolut node 4 (13% versus 2%; P<0.001), and the highest at Evolut node 5 (61% versus 32%; P<0.001). CONCLUSIONS Coronary accessibility after Sapien-3 in Evolut redo-TAVR relates to the initial Evolut implant depth, the Sapien-3 outflow position within the Evolut, and the native annular anatomy. This CT-based quantitative analysis may provide useful information to inform and refine individualized preprocedural CT planning of the initial TAVR and guide lifetime management for future coronary access after redo-TAVR.

Abstract
BACKGROUND Patients with severe tricuspid regurgitation (TR) exhibit high morbidity and mortality. Tricuspid transcatheter edge-to-edge repair (T-TEER) is a rapidly evolving strategy to address the unmet clinical need of severe TR therapies. OBJECTIVE Organize the current body of evidence on outcomes following use of the PASCAL (Edwards Lifesciences) system for T-TEER. METHODS For this meta-analysis, we searched the MEDLINE/PubMed, Embase, and Cochrane databases for keywords ["tricuspid"] and ["transcatheter" or "edge-to-edge"] and ["PASCAL" or "leaflet repair" or "valve repair"] from the database inception until January 11, 2023. Primary outcomes of interest were procedural success, mortality, New York Heart Association (NYHA) functional class, 6-min walking distance (6MWD), and TR severity. RESULTS A total of 549 patients undergoing PASCAL or PASCAL Ace T-TEER were included. The mean age ranged from 71.0 to 80.3 years, with 25.0 to 63.6% females. The follow-up duration ranged from 30 days to 1 year. The success rate was 83.5% (409/490). There was improvement in symptoms based on NYHA classification (at 1- to 6-months; NYHA ≥3 RR 0.27 [95% CI 0.19-0.39]; p < 0.001) and 6MWD (at 1-month; 50.96 [95% CI 32.34-69.59]; p < 0.001) post-procedure. On imaging, there was improvement in TR severity post-procedure (at 1- to 12-months; ≥ severe TR 0.21 [95% CI 0.14-0.31]; p < 0.001), which remained significant with each study removed. CONCLUSION PASCAL for T-TEER is associated with high procedural success rates along with improvements in NYHA functional class, TR severity, 6MWD, and patient-reported outcomes.
