Abstract Aims Many efforts have been made in the last decade to minimize the risk of bleeding in patients undergoing transcatheter aortic valve replacement (TAVR), such as a less intensive antithrombotic therapy and technical improvement in devices implantation. Conversely, evidence on high atherothrombotic status (HATR) is still lacking in patients undergoing TAVR. Accordingly, in this analysis, we aimed to evaluate frequency and impact of atherothrombotic status in patients undergoing transcatheter aortic valve replacement. Methods Patients who underwent TAVR at our Institution from September 2008 to November 2020 were included in this analysis. Out of 407 patients, 6 (1.5%) were excluded as they underwent only balloon angioplasty or for procedural unsuccess. HATR status includes patients with prior percutaneous coronary intervention/coronary artery bypass graft, prior stroke/transient ischaemic attack (TIA), or with a diagnosis of diabetes. Continuous variables following normal distribution were compared with the student’s t-test and categorical data were analysed with the chi-square test. A Cox regression model was used to evaluate the association between HART status and all-cause mortality at one 1-year follow-up. Results Compared to patients with low atherothrombotic status (LATR) (n = 238; 59.4%), HART patients (n = 163; 40.6%) were older, more likely female and with a higher prevalence of common cardiovascular risk factors including chronic kidney disease, smoke, and hyperlipidaemia. Between LATR and HATR groups, no differences have been observed, in terms of procedural time, type of devices used (Balloon vs. self-expandable device), or hospitalization length. Compared to LART, HART patients were more likely to be discharged on statin (63.7% vs. 83%, P < 000.1), on dual antiplatelet therapy (50.4% vs.58.9%, P = 0.03), or on oral anticoagulant if required (27.7% vs. 29.5%, P = 0.03). Furthermore, no differences have been observed in terms of in-hospital adverse events, including death, severe bleeding, any conduction disturbances requiring pacemaker implantation, access complications, myocardial infarction, or stroke/TIA. For instance, HART was not a predictor of mortality at 1 year follow-up, even after adjustment for baseline characteristics. Conclusion In our population, no differences in procedural and in-hospital adverse events have been observed according to the atherothrombotic profile. HATR patients were more likely to be discharged with more intensive antithrombotic and hypolipidaemic strategies, despite the coexistent high prevalence of bleeding determinants. However, ATR status does not impact 1-year mortality even after adjustment for baseline characteristics.

Long Term Mortality

Introduction: Mortality following Transcatheter aortic valve replacement (TAVR) has been reported up to 5 years. However, mortality after 5 years remains unclear. Hypothesis: We aim to determine the mortality in patients undergoing TAVR >5 years follow up. Methods: From our institution’s prospectively collected TAVR database we analyzed all patients undergoing TAVR to a maximum follow up of 8 years. We divided our population into transapical TAVR (TA-TAVR) and transfemoral TAVR (TF-TAVR) groups. A Kaplan-Meier survival analysis was conducted. Results: A total of 511 patients who underwent TAVR were included in the analysis. Patients undergoing TA-TAVR had higher rates of peripheral vascular disease compared with TF-TAVR (56% vs 29%, p<0.001) and Society of Thoracic Surgeons Score (10.9 ± 4 vs 9.2 ± 4, p<0.001). TA-TAVR was associated with higher mortality at 1 year (32% vs 21%, p=0.01). However, there was no significant difference in very-long term mortality of patients undergoing TA-TAVR vs TF-TAVR (Figure). Conclusions: Long-term mortality following TAVR surpasses 50%. While in the first 2 years TA-TAVR is associated with higher mortality rates after three years the survival rates are similar in both approaches.

Abstract Background Electrocardiographic (ECG) strain pattern has recently been associated with increased adverse outcome in aortic stenosis (AS) and after surgical aortic valve replacement (AVR). However, the relation linking ECG strain and cardiovascular MACE in patients with transcatheter aortic valve replacement (TAVR) has not been yet described. Objectives The aim of our study was to determine the impact and incremental value of ECG Strain pattern in predicting adverse outcome after TAVR. Methods 585 patients with severe AS (mean age: 83±7 male 39.8%) were enrolled from November 2012 to May 2018. ECG strain pattern was defined as ≥1 mm concave down-sloping ST-segment depression and asymmetrical T-wave inversion in the lateral leads. Patients with baseline left bundle branch block (LBBB), right bundle branch block (RBBB) or ventricular paced rhythm were excluded. All patients underwent transthoracic echocardiography (TTE) before TAVR and at 30 days follow up. The primary endpoints of the study were the overall all-cause mortality after TAVR, rehospitalization for Hearth failure (HF), myocardial infarction and stroke. Results 178 (30.4%) patients were excluded from analyses owing to the presence of either LBBB (n=103) or RBBB (n=75). Among the 407 remaining patients, 106 had ECG strain pattern (26.04%). Patients with ECG strain were significantly younger (81.6±8 years vs 83.5±6.8 years; p=0.022), had lower BMI (23±4.5 kg.m2 vs 27.9±6.8 kg.m2; p=0.02) more severe AS (mean gradient 52.3±15.2 mmHg vs 47.9±11.8 mmHg; p=0.003), significant lower LVEF (51.8±15% vs 58.4±10.7%; p<0.001). Left ventricular hypertrophy (LVH) was more frequent in patients with ECG Strain (indexed left ventricular mass (135.9±33.4 g.m2 vs 123.6±31.9 g.m2; p=0.002)). Death from any cause (22 (20.8%) vs 61 (20.3%); p=0.508) did not differ significantly between groups. Major adverse cardiovascular events (MACE) including death, stroke and heart failure at 1 month showed similar incidence (7 (6.6%) vs 17 (5.6%), p=0.439). Rehospitalization for hearth failure (HF) was significantly higher (33 (31.1%) vs 33 (11%); p<0.001) in patients with ECG strain pattern. In univariate model, ECG Strain was a strong predictor of rehospitalization for HF (HR 2.621 95% CI (1.607–4.277), p=0.001), independently of LVH assessed either by ECG criteria (HR 1.181 95% CI (0.698–1.997; p=0.536) or TTE (HR 1.557 95% (CI 0.701–3.458; p=0.277). ECG Strain remained associated with a higher risk of rehospitalization for hearth failure in multivariate analyses (HR 2.747 95% (CI 1.614- 4.674); p<0.001) Conclusion In patients with AS eligible for TAVR, ECG Strain Pattern is frequent and associated with an increased risk of post interventional heart failure regardless of preoperative LVH. ECG Strain pattern represents an easy, objective, reliable and low-cost tool to identify patients who may benefit from an extend and intensified post-interventional follow-up.

Baseline Characteristics

Abstract Introduction Women comprise ≥50% patients undergoing transcatheter aortic valve replacement (TAVR). Women have different baseline clinical characteristics and some studies have suggested that TAVR procedure carries better results and prognosis. Purpose Evaluate gender differences in baseline characteristics and long-term outcomes in patients with aortic stenosis undergoing TAVR. Methods A cohort study was conducted. Consecutive patients underwent TAVR from January 2012 to December 2020 were included. Clinical and follow-up characteristics were recorded. MACE (major adverse cardiovascular events including all-cause mortality, myocardial infarction, cerebrovascular accident and heart failure hospitalization) as primary outcome was searched. Results A total of 292 consecutive patients were included. 48.95% were women and median age was 81.07 years (77.73–86.22). 77% TAVR patients received self-expanding prosthesis. Compared with men, women were significantly older and had lower glomerular filtration rate but a lower prevalence of comorbid conditions, such as atrial fibrillation (AF), coronary and peripheral arterial disease (PAD) and cerebrovascular disease. Left ventricular ejection fraction (LVEF) was higher in women. Global baseline characteristics and events at follow-up are summarized in figure 1. At a median follow up of 21.30 (8.52–38.94) months, MACE were lower in women (Odds ratio [OR] 0.60 95% CI: 0.36–1.00). Additionally, women showed lower rates of heart failure hospitalizations (OR 0.34 95% CI 0.16–0.70). There were no statistically significant differences in all-cause mortality. Survival curves for the endpoint of heart failure hospitalizations are represented in figure 2, showing a significant difference between men and women, and demonstrating that the latter present fewer events during follow-up (HR 0.42 95% CI 0.21–0.83). Conclusion In our study, female TAVR recipients had better outcomes than men. The possible reasons for this female-sex-related benefit could be due to better LVEF and fewer comorbidities. Understanding the reasons why men have worse prognostic post-TAVR is essential for guarantee appropriate treatment selection, as well as for achieving the best possible long-term and safety outcomes.
