RESUMEN
BACKGROUND/PURPOSE: Acute kidney injury (AKI) after transcatheter aortic valve implantation (TAVI) increases morbidity and mortality. Our study aimed to investigate the role of baseline N-terminal pro B-type natriuretic peptide (NT-proBNP) as a predictor of AKI following TAVI. METHODS: All consecutive TAVI patients were included in the analysis, except patients with dialysis and those with a GFR < 15 ml/min/1.73 m2 at baseline. Rates of AKI after TAVI were assessed according to the updated valve academic research consortium definitions using AKIN classification in three stages. NT-proBNP was measured at baseline. One-year mortality rates were assessed. RESULTS: We included 1973 patients treated with TAVI between January 2006 and December 2016. Median [IQR] age was 81.0 [77.0;84.0] years, the STS score was 6.2 [3.9;9.0], and the logEuroScore was 14.5 [9.0;23.0]. 30-day and one-year mortality was 5.1 % and 16.1 % for all patients, respectively. Multivariate analysis revealed that patients with NT-proBNP levels higher than two times above the upper level of normal (ULN) had an increased risk for AKI after TAVI compared to patients with NT-proBNP levels < 2× ULN (OR 1.40 [1.03-1.91]). CONCLUSIONS: Routine assessment of baseline NT-proBNP levels might be an additional tool to identify patients at increased risk for AKI after TAVI.
RESUMEN
Background: Red blood cell distribution width (RDW) is calculated in every blood count test and reflects variability in erythrocyte size. High levels mirror dysregulated erythrocyte homeostasis and have been associated with clonal hematopoiesis as well as higher mortality in several conditions.We aimed to determine the impact of preprocedural RDW levels on functional outcomes after transcatheter aortic valve implantation (TAVI). Methods: In this single-center retrospective study, we analyzed 176 consecutive patients receiving TAVI between 2017 and 2021. RDW upper limit of normal was < 15 %. Patients were stratified according to preprocedural RDW as having normal or elevated values. We assessed all-cause-mortality and a composite endpoint comprising cardiovascular/ valve-related mortality and cardiovascular, valve-related and heart failure hospitalization at 1 year. Results: 43 patients (24.4 %) had RDW ≥ 15 %. There were significant baseline differences between groups (Society of Thoracic Surgeons - Predicted Risk of Mortality score 3.18 %[interquartile range 1.87-5.47] vs. 6.63 %[4.12-10.54] p < 0.001; hemoglobin 13.2 g/dL[11.8-14.1] vs. 10.4 g/dL[9.8-12.2], p < 0.001, RDW-normal vs. RDW-high, respectively). Age was not distinct (80.2 years [77.5-84.1] vs 81.2[71.3-84.7], p = 0.78). 1-year-all-cause mortality was not different (7.9 % vs. 9.4 %, p = 0.79). The RDW-high group showed markedly higher NT-proBNP levels after 1 year (647 ng/ml[283-1265] vs. 1893 ng/ml[744-5109], p = 0.005), and experienced more clinical endpoints (hazard ratio 2.57[1.28-5.16] for the composite endpoint, p = 0.006). RDW remained an independent predictor of the composite endpoint when accounting for all baseline differences in multivariable regression. Conclusion: Elevated preprocedural RDW identifies patients at risk for impaired functional outcome after TAVI and may represent a useful low-cost parameter to guide intensity of outpatient surveillance strategies.
RESUMEN
BACKGROUND: We evaluated the outcome of PCI of de novo stenosis with drug-coated balloons (DCB) versus drug-eluting stents (DES) in patients with insulin-treated diabetes mellitus (ITDM) versus non-insulin-treated diabetes mellitus (NITDM). METHODS: Patients were randomized in the BASKET-SMALL 2 trial to DCB or DES and followed over 3 years for MACE (cardiac death, non-fatal myocardial infarction [MI], and target vessel revascularization [TVR]). Outcome in the diabetic subgroup (n = 252) was analyzed with respect to ITDM or NITDM. RESULTS: In NITDM patients (n = 157), rates of MACE (16.7% vs. 21.9%, hazard ratio [HR] 0.68, 95% confidence interval [CI] 0.29-1.58, p = 0.37), death, non-fatal MI, and TVR (8.4% vs. 14.5%, HR 0.30, 95% CI 0.09-1.03, p = 0.057) were similar between DCB and DES. In ITDM patients (n = 95), rates of MACE (DCB 23.4% vs. DES 22.7%, HR 1.12, 95% CI 0.46-2.74, p = 0.81), death, non-fatal MI, and TVR (10.1% vs. 15.7%, HR 0.64, 95% CI 0.18-2.27, p = 0.49) were similar between DCB and DES. TVR was significantly lower with DCB versus DES in all diabetic patients (HR 0.41, 95% CI 0.18-0.95, p = 0.038). CONCLUSIONS: DCB compared to DES for treatment of de novo coronary lesions in diabetic patients was associated with similar rates of MACE and numerically lower need for TVR both for ITDM and NITDM patients.
RESUMEN
To evaluate the prognostic relevance of aortic annulus (AA) and left ventricular outflow tract (LVOT) Fractal dimension (FD). FD is a mathematical concept that describes geometric complexity of a structure and has been shown to predict adverse outcomes in several contexts. Computed tomography (CT) scans from the SOLVE-TAVI trial, which, in a 2 × 2 factorial design, randomized 447 patients to TAVI with the balloon-expandable Edwards Sapien 3 or the self-expanding Medtronic Evolut R, and conscious sedation or general anesthesia, were analyzed semi-automatically with a custom-built software to determine border of AA and LVOT. FD was measured by box counting using grid calibers between 0.8 and 6.75 mm and was compared between patients with none/trivial and mild/moderate paravalvular regurgitation (PVR). Overall, 122 patients had CT scans sufficient for semi-automatic PVR in 30-day echocardiography. PVR was none in 65(53.3%) patients, trace in 9(7.4%), mild in 46(37.7%), moderate in 2(1.6%) and severe in 0 patients. FD determined in diastolic images was significantly higher in patients with mild/moderate PVR (1.0558 ± 0.0289 vs. 1.0401 ± 0.0284, p = 0.017). Annulus eccentricity was the only conventional measure of AA and LVOT geometry significantly correlated to FD (R = 0.337, p < 0.01). Area under the curve (AUC) of diastolic annular FD for prediction of mild/moderate PVR in ROC analysis was 0.661 (0.542-0.779, p = 0.014). FD shows promise in prediction of PVR after TAVI. Further evaluation using larger patient numbers and refined algorithms to better understand its predictive performance is warranted.Trial Registration: www.clinicaltrials.gov , identifier: NCT02737150, date of registration: 13.04.2016.

BACKGROUND: Left ventricular outflow tract (LVOT) calcification has been associated with worse outcomes in patients undergoing transcatheter aortic valve implantation (TAVI) and may influence the selection of prosthetic valve type. AIMS: We aimed to evaluate the impact of LVOT calcification on outcomes after TAVI with a self-expanding valve (SEV) versus a balloon-expandable valve (BEV). METHODS: Patients of the SOLVE-TAVI trial, randomised to Edwards SAPIEN 3 or Medtronic Evolut R, were divided according to LVOT calcification into no/mild (≤1 calcium nodule extending <5 mm and covering <10% of the LVOT perimeter) and moderate/severe LVOT calcification groups. The primary endpoint was a composite of death, stroke, moderate/severe paravalvular regurgitation, permanent pacemaker implantation and annulus rupture at 30 days. Additional endpoints included all-cause and cardiovascular mortality at 1 year. RESULTS: Out of 416 eligible patients, moderate/severe LVOT calcification was present in 143 (34.4%). Moderate/severe LVOT calcification was associated with significantly longer fluoroscopy time and higher rates of pre- and post-dilation. Regardless of the LVOT calcification group, there was no significant difference in the primary endpoint associated with the valve type (no/mild LVOT calcification group: SEV 25.0% vs BEV 27.0%; hazard ratio [HR] 1.10, 95% confidence interval [95% CI]: 0.68-1.73; p=0.73 and moderate/severe LVOT calcification group: SEV 25.0% vs BEV 19.4%; HR 0.76, 95% CI: 0.38-1.61; p=0.49), no significant interaction between LVOT calcification and valve type (pint=0.29) and no differences between SEV vs BEV within LVOT calcification groups regarding 1-year all-cause and cardiovascular mortality. CONCLUSIONS: Moderate/severe LVOT calcification was associated with longer fluoroscopy time and an increased need for pre- and post-dilation, but not with a higher incidence of early and mid-term adverse clinical outcomes, regardless of valve type.

BACKGROUND: Drug-coated balloons (DCBs) are an established treatment strategy for coronary artery disease. Randomized data on the application of DCBs in patients with an acute coronary syndrome (ACS) are limited. We evaluated the impact of clinical presentation (ACS versus chronic coronary syndrome) on clinical outcomes in patients undergoing DCB or drug-eluting stent (DES) treatment in a prespecified analysis of the BASKET-SMALL 2 trial (Basel Kosten Effektivitäts Trial-Drug-Coated Balloons Versus Drug-Eluting Stents in Small Vessel Interventions). METHODS: BASKET-SMALL 2 randomized 758 patients with small vessel coronary artery disease to DCB or DES treatment and followed them for 3 years regarding major adverse cardiac events (cardiac death, nonfatal myocardial infarction, and target vessel revascularization). RESULTS: Among 758 patients, 214 patients (28.2%) presented with an ACS (15 patients [7%], ST-segment-elevation myocardial infarction; 109 patients [50.9%], non-ST-segment-elevation myocardial infarction; 90 patients [42.1%], unstable angina pectoris). At 1-year follow-up, there was no significant difference in the incidence of the primary end point by randomized treatment in patients with ACS (hazard ratio, 0.50 [95% CI, 0.19-1.26] for DCB versus DES) or chronic coronary syndrome (hazard ratio, 1.29 [95% CI, 0.67-2.47] for DCB versus DES). There was no significant interaction between clinical presentation and treatment effect (P for interaction, 0.088). For cardiac death (P for interaction, 0.049) and nonfatal myocardial infarction (P for interaction, 0.010), a significant interaction between clinical presentation and treatment was seen at 1 year with lower rates of these secondary end points in patients with ACS treated by DCB. At 3 years, there were similar major adverse cardiac event rates throughout groups without significant interaction between clinical presentation and treatment (P for interaction, 0.301). All-cause mortality was higher in ACS compared with chronic coronary syndrome; however, there was no difference between DCB and DES irrespective of clinical presentation. CONCLUSIONS: In this subgroup analysis of the BASKET-SMALL 2 trial, there was no interaction between indication for percutaneous coronary intervention (acute versus chronic coronary syndrome) and treatment effect of DCB versus DES in patients with small vessel coronary artery disease.

OBJECTIVES: The study sought to evaluate the impact of diabetes mellitus on 3-year clinical outcome in patients undergoing drug-coated balloon (DCB) or drug-eluting stent (DES) treatment for de novo lesions. BACKGROUND: For treatment of de novo coronary small vessel disease, DCBs are noninferior to DES. METHODS: In this prespecified analysis of a multicenter, randomized, noninferiority trial, including 758 patients with de novo lesions in coronary vessels <3 mm who were randomized 1:1 to DCB or DES and followed over 3 years for major adverse cardiac events (MACE) (cardiac death, nonfatal myocardial infarction [MI], and target vessel revascularization [TVR]), outcome was analyzed regarding the presence or absence of diabetes mellitus. RESULTS: In nondiabetic patients (n = 506), rates of MACE (DCB 13.0% vs DES 11.5%; hazard ratio [HR]: 1.24; 95% confidence interval [CI]: 0.73-2.09; P = 0.43), cardiac death (2.8% vs 2.9%; HR: 0.97; 95% CI: 0.32-2.92; P = 0.96), nonfatal MI (5.1% vs 4.8%; HR: 1.00; 95% CI: 0.44-2.28; P = 0.99), and TVR (8.8% vs 6.1%; HR: 1.64; 95% CI: 0.83-3.25; P = 0.16) were similar. In diabetic patients (n = 252), rates of MACE (19.3% vs 22.2%; HR: 0.82; 95% CI: 0.45-1.48; P = 0.51), cardiac death (8.8% vs 5.9%; HR: 2.01; 95% CI: 0.76-5.31; P = 0.16), and nonfatal MI (7.1% vs 9.8%; HR: 0.55; 95% CI: 0.21-1.49; P = 0.24) were similar in DCB and DES. TVR was significantly lower with DCBs vs DES (9.1% vs 15.0%; HR: 0.40; 95% CI: 0.17-0.94; P = 0.036; P = 0.011 for interaction). CONCLUSIONS: The rates of MACE are similar in DCBs and DES in de novo coronary lesions of diabetic and nondiabetic patients. In diabetic patients, need for TVR was significantly lower with DCB versus DES.

BACKGROUND: Transcatheter aortic valve replacement (TAVR) has become the standard of care in the majority of patients with symptomatic severe aortic stenosis. Data on long-term mortality and durability of transcatheter heart valves (THVs) beyond 5 years are limited. Our study aimed to assess elderly and high-risk patients' long-term outcomes treated with TAVR in a prospective single-centre registry focusing on the durability of THVs. METHODS: We included 795 patients with severe calcific aortic stenosis treated by transfemoral TAVR between 2006 and 2011. Echocardiography was performed at baseline; discharge; 1 year; and afterward, annually, until the longest available follow-up. Mortality rates were estimated for 1, 5, 6, 7, and 8 years. The rates of structural valve deterioration (SVD) and bioprosthetic valve failure (BVF) were assessed in accordance with consensus definitions. Outcome measures were adjudicated according to Valve Academic Research Consortium-2 (VARC-2). RESULTS: Median (interquartile range) follow-up time was 1345 (316; 2015) days. One-year, 5-year, 6-year, 7-year, and 8-year overall mortality was 25.4%, 59.0%, 64.6%, 67.9%, and 69.2%, respectively. At 8 years, no significant differences in mortality were found comparing self-expanding vs balloon-expandable valves (69.5% vs 68.0%, P = 0.709) and postdilatation (PD) vs no-PD (69.4% vs 69.2%, P = 0.363). SVD was detected in 26 patients (3.3%), and 19 (2.4%) of the 795 patients had evidence of BVF during follow-up. CONCLUSIONS: Our study demonstrates good long-term results for high-risk patients who were alive up to 8 years after TAVR.
CONTEXTE: Le remplacement valvulaire aortique par cathéter (RVAC) est maintenant la norme de soins dans la majorité des cas de sténose de l'aorte grave symptomatique. On dispose de peu de données sur la mortalité à long terme et sur la durabilité des valves cardiaques transcathéter (VCT) au-delà de 5 ans. Nous avons donc évalué les résultats à long terme, notamment la durabilité des VCT, chez les patients âgés et les patients exposés à un risque élevé traités par RVAC figurant dans un registre prospectif unicentrique. MÉTHODOLOGIE: Notre étude comprenait 795 patients présentant une sténose calcifiée de l'aorte grave traitée par RVAC transfémoral entre 2006 et 2011. Une échocardiographie a été réalisée au départ, à la sortie de l'hôpital, 1 an plus tard et tous les ans par la suite, jusqu'au suivi le plus long disponible. Les taux de mortalité à 1, 5, 6, 7 et 8 ans ont été estimés. Les taux de détérioration structurelle des valves (DSV) et de défaillance de la bioprothèse valvulaire (DBV) ont été évalués selon des définitions établies par consensus. Les mesures des résultats ont été confirmées selon les critères du VARC-2 (Valve Academic Research Consortium-2). RÉSULTATS: La durée médiane (intervalle interquartile) du suivi était de 1 345 (316 à 2 015) jours. Les taux de mortalité globaux s'établissaient comme suit : taux à 1 an : 25,4 %; à 5 ans : 59,0 %; à 6 ans : 64,6 %; à 7 ans : 67,9 % et à 8 ans : 69,2 %. À 8 ans, on n'a noté aucune différence significative en ce qui concerne la mortalité chez les patients ayant reçu une valve auto-expansible comparativement à ceux ayant reçu une valve expansible par ballonnet (69,5 % vs 68,0 %; p = 0,709) et chez ceux ayant subi une post-dilatation ou non (69,4 % vs 69,2 %; p = 0,363). Une DSV a été détectée chez 26 patients (3,3 %), et 19 (2,4 %) des 795 patients ont présenté des signes de DBV pendant la période de suivi. CONCLUSIONS: Notre étude a révélé de bons résultats à long terme chez les patients présentant un risque élevé qui étaient toujours en vie 8 ans après le RVAC.
RESUMEN
BACKGROUND: The randomized SOLVE-TAVI (compariSon of secOnd-generation seLf-expandable vs. balloon-expandable Valves and gEneral vs. local anesthesia in Transcatheter Aortic Valve Implantation) trial compared newer-generation self-expanding valves (SEV) and balloon-expandable valves (BEV) as well as local anesthesia with conscious sedation (CS) and general anesthesia (GA) in patients undergoing transfemoral transcatheter aortic valve replacement (TAVR). Both strategies showed similar outcomes at 30 days. OBJECTIVES: The purpose of this study was to compare clinical outcomes during 1-year follow-up in the randomized SOLVE-TAVI trial. METHODS: Using a 2 × 2 factorial design 447 intermediate- to high-risk patients with severe, symptomatic aortic stenosis were randomly assigned to transfemoral TAVR using either the SEV (Evolut R, Medtronic Inc., Minneapolis, Minnesota) or the BEV (Sapien 3, Edwards Lifesciences, Irvine, California) as well as CS or GA at 7 sites. RESULTS: In the valve-comparison strategy, rates of the combined endpoint of all-cause mortality, stroke, moderate or severe paravalvular leakage, and permanent pacemaker implantation were similar between the BEV and SEV group (n = 84, 38.3% vs. n = 87, 40.4%; hazard ratio: 0.94; 95% confidence interval: 0.70 to 1.26; p = 0.66) at 1 year. Regarding the anesthesia comparison, the combined endpoint of all-cause mortality, stroke, myocardial infarction, and acute kidney injury occurred with similar rates in the GA and CS groups (n = 61, 25.7% vs. n = 54, 23.8%; hazard ratio: 1.09; 95% confidence interval: 0.76 to 1.57; p = 0.63). CONCLUSIONS: In intermediate- to high-risk patients undergoing transfemoral TAVR, newer-generation SEV and BEV as well as CS and GA showed similar clinical outcomes at 1 year using a combined clinical endpoint.

BACKGROUND: Data about the impact of left-atrial appendage thrombosis (LAAT) on early safety and mortality in patients undergoing transfemoral transcatheter aortic valve implantation (TF-TAVI) are scarce. We aimed to investigate the prevalence and predictors of LAAT and the outcome associated with this condition in patients treated by TF-TAVI. METHODS: Retrospective data analysis was derived from a prospective single-centre registry comparing patients with and without LAAT regarding early safety at 30 days, according to Valve Academic Research Consortium-2 (VARC-2) and 2-year mortality. RESULTS: LAAT was found in 7.6% of the whole cohort (n = 2527) and in 16.6% in those patients with known pre-existing atrial fibrillation (AF cohort, n = 1099). Compared with controls, patients with LAAT were sicker, indicated by a higher Society of Thoracic Surgeons (STS) score and burden of comorbidities. Neither VARC-2-defined early safety at 30 days nor the rate of stroke was different between LAAT and controls in both the whole (early safety: 29.2% vs 24.2%, P = 0.123; stroke: 5.9% vs 4.7%, P = 0.495) and AF cohort (early safety: 29.1% vs 22.9%, P = 0.072; stroke: 5.6% vs 3.3%, P = 0.142). Evaluating the whole cohort in a univariate analysis, the 2-year mortality was significantly higher in LAAT compared with controls (hazard ratio, 1.41; 95% confidence interval, 1.07-1.86; P = 0.014). However, multivariate analysis of the whole cohort and the AF cohort revealed no association between LAAT and 2-year mortality. CONCLUSIONS: LAAT was frequent in patients undergoing TF-TAVI- in particular, in patients with histories of AF-but it was not associated with an increase in periprocedural complications and did not predict 2-year mortality.

BACKGROUND: In the treatment of de-novo coronary small vessel disease, drug-coated balloons (DCBs) are non-inferior to drug-eluting stents (DESs) regarding clinical outcome up to 12 months, but data beyond 1 year is sparse. We aimed to test the long-term efficacy and safety of DCBs regarding clinical endpoints in an all-comer population undergoing percutaneous coronary intervention. METHODS: In this prespecified long-term follow-up of a multicentre, randomised, open-label, non-inferiority trial, patients from 14 clinical sites in Germany, Switzerland, and Austria with de-novo lesions in coronary vessels <3 mm and an indication for percutaneous coronary intervention were randomly assigned 1:1 to DCB or second-generation DES and followed over 3 years for major adverse cardiac events (ie, cardiac death, non-fatal myocardial infarction, and target-vessel revascularisation [TVR]), all-cause death, probable or definite stent thrombosis, and major bleeding (Bleeding Academic Research Consortium bleeding type 3-5). Analyses were performed on the full analysis set according to the modified intention-to-treat principle. Dual antiplatelet therapy was recommended for 1 month after DCB and 6 months after DES with stable symptoms, but 12 months with acute coronary syndromes. The study is registered with ClinicalTrials.gov, NCT01574534 and is ongoing. FINDINGS: Between April 10, 2012, and Feb 1, 2017, of 883 patients assessed, 758 (86%) patients were randomly assigned to the DCB group (n=382) or the DES group (n=376). The Kaplan-Meier estimate of the rate of major adverse cardiac events was 15% in both the DCB and DES groups (hazard ratio [HR] 0·99, 95% CI 0·68-1·45; p=0·95). The two groups were also very similar concerning the single components of adverse cardiac events: cardiac death (Kaplan-Meier estimate 5% vs 4%, HR 1·29, 95% CI 0·63-2·66; p=0·49), non-fatal myocardial infarction (both Kaplan-Meier estimate 6%, HR 0·82, 95% CI 0·45-1·51; p=0·52), and TVR (both Kaplan-Meier estimate 9%, HR 0·95, 95% CI 0·58-1·56; p=0·83). Rates of all-cause death were very similar in DCB versus DES patients (both Kaplan-Meier estimate 8%, HR 1·05, 95% CI 0·62-1·77; p=0·87). Rates of probable or definite stent thrombosis (Kaplan-Meier estimate 1% vs 2%; HR 0·33, 95% CI 0·07-1·64; p=0·18) and major bleeding (Kaplan-Meier estimate 2% vs 4%, HR 0·43, 95% CI 0·17-1·13; p=0·088) were numerically lower in DCB versus DES, however without reaching significance. INTERPRETATION: There is maintained efficacy and safety of DCB versus DES in the treatment of de-novo coronary small vessel disease up to 3 years.

BACKGROUND: In clinical practice, local anesthesia with conscious sedation (CS) is performed in roughly 50% of patients undergoing transcatheter aortic valve replacement. However, no randomized data assessing the safety and efficacy of CS versus general anesthesia (GA) are available. METHODS: The SOLVE-TAVI (Comparison of Second-Generation Self-Expandable Versus Balloon-Expandable Valves and General Versus Local Anesthesia in Transcatheter Aortic Valve Implantation) trial is a multicenter, open-label, 2×2 factorial, randomized trial of 447 patients with aortic stenosis undergoing transfemoral transcatheter aortic valve replacement comparing CS versus GA. The primary efficacy end point was powered for equivalence (equivalence margin 10% with significance level 0.05) and consisted of the composite of all-cause mortality, stroke, myocardial infarction, infection requiring antibiotic treatment, and acute kidney injury at 30 days. RESULTS: The primary composite end point occurred in 27.2% of CS and 26.4% of GA patients (rate difference, 0.8 [90% CI, -6.2 to 7.8]; Pequivalence=0.015). Event rates for the individual components were as follows: all-cause mortality, 3.2% versus 2.3% (rate difference, 1.0 [90% CI, -2.9 to 4.8]; Pequivalence<0.001); stroke, 2.4% versus 2.8% (rate difference, -0.4 [90% CI, -3.8 to 3.8]; Pequivalence<0.001); myocardial infarction, 0.5% versus 0.0% (rate difference, 0.5 [90% CI, -3.0 to 3.9]; Pequivalence<0.001), infection requiring antibiotics 21.1% versus 22.0% (rate difference, -0.9 [90% CI, -7.5 to 5.7]; Pequivalence=0.011); acute kidney injury, 9.0% versus 9.2% (rate difference, -0.2 [90% CI, -5.2 to 4.8]; Pequivalence=0.0005). There was a lower need for inotropes or vasopressors with CS (62.8%) versus GA (97.3%; rate difference, -34.4 [90% CI, -41.0 to -27.8]). CONCLUSIONS: Among patients with aortic stenosis undergoing transfemoral transcatheter aortic valve replacement, use of CS compared with GA resulted in similar outcomes for the primary efficacy end point. These findings suggest that CS can be safely applied for transcatheter aortic valve replacement. Registration: URL: https://www.clinicaltrials.gov; Unique identifier: NCT02737150.

Background As transcatheter aortic valve replacement (TAVR) is expected to progress into younger patient populations, valve-in-TAVR (ViTAVR) may become a frequent consideration. Data on ViTAVR, however, are limited. This study investigated the outcome of ViTAVR in comparison to valve in surgical aortic valve replacement (ViSAVR), because ViSAVR is an established procedure for higher-risk patients requiring repeated aortic valve intervention. Methods and Results Clinical and procedural data of patients who underwent ViTAVR at 3 sites in the United States and Germany were retrospectively compared with data of patients who underwent ViSAVR at Cedars-Sinai Medical Center, according to Valve Academic Research Consortium-2 criteria. A total of 99 consecutive patients, 52.5% women, with a median Society of Thoracic Surgeons score of 7.2 were identified. Seventy-four patients (74.7%) underwent ViSAVR, and 25 patients (25.3%) underwent ViTAVR. Balloon-expandable devices were used in 72.7%. ViSAVR patients presented with smaller index devices (21.0 versus 26.0 mm median true internal diameter; P<0.001). Significantly better postprocedural hemodynamics (median prosthesis mean gradient, 12.5 [interquartile range, 8.8-16.2] versus 16.0 [interquartile range, 13.0-20.5] mm Hg; P=0.045) were observed for ViTAVR compared with the ViSAVR. Device success, however, was not different (79.2% and 66.2% for ViTAVR and ViSAVR, respectively; P=0.35), as were rates of permanent pacemaker implantation (16.7% versus 5.4%; P=0.1). One-year-mortality was 9.4% and 13.4% for ViTAVR and ViSAVR, respectively (log-rank P=0.38). Conclusions Compared with ViSAVR, ViTAVR provides acceptable outcomes, with slightly better hemodynamics, similar device success rates, and similar 1-year mortality.

AIMS: Transcatheter aortic valve implantation (TAVI) has emerged as established treatment option in patients with symptomatic aortic stenosis. Technical developments in valve design have addressed previous limitations such as suboptimal deployment, conduction disturbances, and paravalvular leakage. However, there are only limited data available for the comparison of newer generation self-expandable valve (SEV) and balloon-expandable valve (BEV). METHODS AND RESULTS: SOLVE-TAVI is a multicentre, open-label, 2 × 2 factorial, randomized trial of 447 patients with aortic stenosis undergoing transfemoral TAVI comparing SEV (Evolut R, Medtronic Inc., Minneapolis, MN, USA) with BEV (Sapien 3, Edwards Lifesciences, Irvine, CA, USA). The primary efficacy composite endpoint of all-cause mortality, stroke, moderate/severe prosthetic valve regurgitation, and permanent pacemaker implantation at 30 days was powered for equivalence (equivalence margin 10% with significance level 0.05). The primary composite endpoint occurred in 28.4% of SEV patients and 26.1% of BEV patients meeting the prespecified criteria of equivalence [rate difference -2.39 (90% confidence interval, CI -9.45 to 4.66); Pequivalence = 0.04]. Event rates for the individual components were as follows: all-cause mortality 3.2% vs. 2.3% [rate difference -0.93 (90% CI -4.78 to 2.92); Pequivalence < 0.001], stroke 0.5% vs. 4.7% [rate difference 4.20 (90% CI 0.12 to 8.27); Pequivalence = 0.003], moderate/severe paravalvular leak 3.4% vs. 1.5% [rate difference -1.89 (90% CI -5.86 to 2.08); Pequivalence = 0.0001], and permanent pacemaker implantation 23.0% vs. 19.2% [rate difference -3.85 (90% CI -10.41 to 2.72) in SEV vs. BEV patients; Pequivalence = 0.06]. CONCLUSION: In patients with aortic stenosis undergoing transfemoral TAVI, newer generation SEV and BEV are equivalent for the primary valve-related efficacy endpoint. These findings support the safe application of these newer generation percutaneous valves in the majority of patients with some specific preferences based on individual valve anatomy.

OBJECTIVES: To evaluate the impact of previous coronary artery bypass grafting (CABG) on early safety at 30 days and 1-year mortality in patients receiving transcatheter aortic valve replacement (TAVR). BACKGROUND: The use of TAVR in patients with previous CABG suffering from severe aortic stenosis has increased in the last years. METHODS: Consecutive TAVR patients were stratified according to previous CABG versus no previous cardiac surgery (control). All-cause 1-year mortality and early safety at 30 days were evaluated. RESULTS: In the unmatched cohort and compared to control (n = 2,364), CABG (n = 260) were younger, more often male and suffered more often from comorbidities leading to an increased STS-score (p < .001). The rate of early safety events at 30 days was comparable between CABG and control (21.2% vs. 24.6%, p = .22) with a higher mortality in CABG (9.6% vs. 5.3%, p = .005). All-cause 1-year mortality was higher in CABG compared to controls (HR 1.51 [95%-CI 1.15-1.97], p = .003). Applying Cox regression analysis, both 30-day (HR 1.57 [95%-CI 0.97-2.53], p = .067) and all-cause 1-year mortality (HR 1.24 [95%-CI 0.91-1.70], p = .174) were not significantly different between groups. After propensity-score matching, the rate of early safety events at 30 days was lower in CABG compared to controls (21.6% vs. 31.7%, p = .02). Thirty-day (9.1% vs. 7.7%, p = .596) and all-cause 1-year mortality (24.0% vs. 23.1%, p = .520, HR 1.14 [95%-CI 0.77-1.69], p = .520) were not different between groups. CONCLUSION: In patients receiving TAVR, previous CABG was not associated with an increase in periprocedural complications and all-cause 1-year mortality when adjusted for other comorbidities.

BACKGROUND: The use of bioprostheses for surgical aortic valve replacement increased substantially within the last years. In case of prosthesis failure, re-SAVR is standard of care, whereas valve-in-valve deployment of a transfemoral transcatheter aortic valve prosthesis (VinV-TFAVI) has recently emerged as an alternative. We sought to evaluate early safety, clinical efficacy, and all-cause 1-year-mortality of VinV-TFAVI and redo surgery for failing aortic bioprostheses (re-SAVR). METHODS AND RESULTS: Patients receiving either VinV-TFAVI (nâ¯=â¯147) or re-SAVR (nâ¯=â¯111) for a degenerated aortic bioprosthesis between 01/2006 and 05/2017 were included in this analysis. All-cause 1-year mortality was the primary outcome measure. Early safety and clinical efficacy according to VARC-2 endpoint definitions were evaluated at 30 days. Baseline characteristics differed significantly between both groups including age, STS-PROM, and incidence of relevant comorbidities. Re-stenosis was the predominant mode of failure in 45.9% of re-SAVR and 63.1% of VinV-TFAVI patients. The rate of "early safety" endpoints was lower with VinV-TFAVI (17.7% vs. 64.9%, pâ¯<â¯0.01), the rate of "clinical efficacy" endpoints was lower, e.g. better with re-SAVR (53.1% vs. 32.4%, pâ¯<â¯0.01). All-cause 1-year-mortality (VinV-TFAVI 8.8% vs re-SAVR 9.9%, pâ¯=â¯0.84) was not different. Treatment strategy was not associated with 1-year-mortality in a Cox regression analysis. The incidence of prosthesis-patient-mismatch was higher in VinV-TFAVI compared to re-SAVR. CONCLUSION: VinV-TFAVI represents a viable alternative for treatment of degenerated aortic bioprostheses in patients at increased surgical risk. However, in patients at low risk for reoperation, a better clinical efficacy and acceptable safety may favour re-SAVR.

The role of continued versus interrupted oral anticoagulation (OAC) in patients with atrial fibrillation (AF) who underwent transfemoral transcatheter aortic valve implantation (TF-TAVI) for severe aortic stenosis is uncertain. The aim of this retrospective investigation was to evaluate the impact (1) of continued versus interrupted OAC on early safety and (2) of postoperative anticoagulant management on the 1-year mortality in patients with AF who underwent TF-TAVI. Consecutive patients with AF and on OAC at admission (nâ¯=â¯598) were stratified according to interrupted (iVKA) versus continued vitamin K antagonist (cVKA) versus continued direct oral anticoagulants (DOAC) at the time of TF-TAVI. Valve Academic Research Consortium-2 early safety was the primary outcome measure. Patients with iVKA (nâ¯=â¯299), cVKA (nâ¯=â¯117), and DOAC (nâ¯=â¯182) had comparable baseline characteristics including age (pâ¯=â¯0.25), gender (pâ¯=â¯0.33), and STS-Score (pâ¯=â¯0.072). The proportion of patients having a CHA2DS2-VASc-Score ≥3 (pâ¯=â¯0.791) and HAS-BLED-Score ≥3 (pâ¯=â¯0.185) was not different between groups. The rate of early safety events (with lower values indicating superior safety) was lowest in DOAC (13.2%) and not increased in cVKA (19.7%) compared to iVKA (23.1%) (pâ¯=â¯0.029). Valve Academic Research Consortium-2 defined stroke (pâ¯=â¯0.527) and bleeding (pâ¯=â¯0.097) did not differ between groups. Renal failure occurred more often in iVKA compared to cVKA and DOAC (pâ¯=â¯0.02). All-cause 1-year mortality was 20.1% in iVKA, 13.7% in cVKA, and 8.8% in DOAC (pâ¯=â¯0.015). Multivariate analysis revealed DOAC to be associated with reduced all-cause 1-year mortality (HR 0.56 (95%-CI 0.32 to 0.99), pâ¯=â¯0.047) whereas cVKA was comparable to iVKA (HR 0.75 (95%-CI 0.43 to 1.31), pâ¯=â¯0.307). In conclusion, cVKA did not increase the rate for the composite end point of early safety at 30 days in this cohort of patients. Treatment with a DOAC was associated with a significantly reduced rate of early safety end points at 30 days and lower 1-year mortality.

BACKGROUND: Diabetes mellitus (DM) is a risk factor for cardiovascular disease. However, its effect on procedural and follow-up performance after transcatheter aortic valve replacement (TAVR) remains controversial. METHODS AND RESULTS: We performed an observational study of all consecutive patients treated with a transfemoral TAVR in a single-center cohort (n = 1818). All patients were stratified by diabetes status and gender. All-cause 3-year mortality was the primary endpoint. Male patients with DM were identified to have substantially increased 3-year mortality [125/314 (39.8%)] compared to males without DM [142/478 (29.7%), p < 0.01]. Male patients with DM had significantly higher 3-year mortality in comparison to female patients with (p < 0.01) or without DM (p < 0.01). There was no difference in 3-year mortality for female patients with [135/465 (29.0%)] and without DM [151/554 (27.3%); p = 0.70]. This increase in mortality in male DM patients was triggered by both cardiovascular and non-cardiovascular mortality. Furthermore, DM served as an independent predictor of 3-year mortality after TAVR selectively only in men. The interaction between male gender and diabetes mellitus was identified as an independent predictor of 3-year mortality [HR 1.88 (1.25; 2.82); p < 0.01]. DM did not affect 30-day mortality for the overall cohort and for males. CONCLUSION: Males with DM are a high-risk subgroup of patients after TAVR and require close medical attention including aggressive therapy of modifiable risk factors. Intensified diabetes management may improve long-term survival after TAVR.
