Abstract Funding Acknowledgements None of the author have conflict of interest to disclose. Background  As transcatheter aortic-valve implantation (TAVI) procedures have increased, the need of a permanent pacemaker (PPM) is a complication to be taken into account.  Objective  The aim of this study is to identify clinical, electrocardiographic (ECG) and procedural predictors for PPM requirement after TAVI. Methods  The present is a single centre, retrospective study. All consecutive patients with severe symptomatic aortic stenosis who underwent TAVI had continuous ECG monitoring. Pre and post TAVI 12-leads ECG were analysed. We arbitrarily divided the patients into early and late PPM implantation (beyond the 3rd day after TAVI). The primary endpoint of the study was to identify electrocardiographic predictors of PPM implantation after TAVI, and the secondary endpoint was to identify other clinical or procedure-related predictive factors. Results  Of 431 patients who underwent TAVI, 77 (18%) required a PPM, and 30 (7%) had late PPM implantations. Pre-operative RBBB implies more than five-fold increase of the risk of PPM implantation after TAVI (OR 5,43, CI 2.11 - 13.99, P = 0.000), whereas the history of syncope is associated with a two-fold increase of the risk (OR 2.00, CI 1.01 - 3.96, P = 0.044), and maintains its predictive value also in the late PPM subgroup (OR 2.76, CI 1.11 – 6.82, P = 0.028). Conclusions  It is hard to predict the need of a PPM in the individual patients, but careful evaluation of pre-operative 12-lead ECG looking for pre-existing RBBB and an history of syncope, can individuate the group of patients with an increased risk of PPM requirement.

Abstract Introduction In recent years, there has been a surge in the utilization of transcatheter aortic valve implantation (TAVI) for the treatment of severe symptomatic aortic stenosis. Randomized controlled trials have compared TAVI to surgical aortic valve replacement (SAVR) in patients at high-, intermediate-, and low perioperative risk. As TAVI continues to be utilized in patients with lower risk profiles, it is important to investigate the temporal trends in “real-world” patients undergoing TAVI. Purpose To investigate temporal trends in the utilization of TAVI and examine changes in patient characteristics of patients undergoing first-time TAVI. Methods Using complete Danish nationwide registries, we included all patients undergoing first-time TAVI between 2008 and 2017. To compare patient characteristics, the study population was stratified according to calendar year in the following groups: 2008–2009, 2010–2011, 2012–2013, 2014–2015, and 2016–2017. Results We identified 3,534 patients undergoing first-time TAVI. In 2008–2009, 180 patients underwent first-time TAVI compared with 1,417 patients in 2016–2017, resulting in a 687% increase in TAVI procedures performed. During the study period, the median age remained stable (2008–2009: Median age 82 year [25th–75th percentile: 78–85] vs. 2016–2017: Median age 81 years [25th–75th percentile: 76–85]; P-value: 0.06). The proportion of men undergoing first-time TAVI increased over the years (2008–2009: 49.4% vs 2016–2017: 54.9%; P-value for trend: <0.05), also the proportion with diabetes increased (2008–2009: 12.2% vs. 2016–2017: 19.3%; P-value for trend: <0.05). The proportion of patients with a history of stroke decreased over the years (2008–2009: 13.9% vs. 2016–2017: 12.1%; P-value for trend: <0.05). The same trend was seen in patients with a history of myocardial infarction (2008–2009: 24.4% vs. 2016–2017: 11.9%; P-value for trend: <0.05), ischaemic heart disease (2008–2009: 71.7% vs. 2016–2017: 29.4%; P-value for trend: <0.05), and heart failure (2008–2009: 45.6% vs. 2016–2017: 29.4%; P-value for trend: <0.05). Conclusions In this nationwide study, there was a marked increase in the utilization of TAVI in the years 2008–2017. Patients undergoing first-time TAVI had a decreasing comorbidity burden, while the age of the patients at first-time TAVI remained stable. Funding Acknowledgement Type of funding source: None

Abstract Introduction Transcatheter aortic valve implantation (TAVI) is an established treatment in patients (P) with aortic stenosis. Despite the continuous developments of this procedure, high-grade conduction disturbances requiring permanent pacemaker (PPM) implantation is still a major and common complication of TAVI. Furthermore, long-term chronic right ventricular pacing has been associated with negative effects on ventricular function and heart failure (HF). Aim   to evaluate the long-term impact of PPM after TAVI focusing on mortality and HF hospitalization. Methods  We retrospectively examined P who underwent TAVI with a self-expanding valve from 2009 to 2018 at our institution. All P had pre-procedural clinical evaluation, including ECG, cardiac computed tomographic angiography and transthoracic echocardiography. P with previous PPM were excluded. Results  265P (57% male, mean age 81.4 years, 20% with left ventricular ejection fraction <40%) were analysed. Mean STS score and mean Euroscore II were 6.33% and 7.07%, respectively. Mean transvalvular gradient was 52.78 mmHg and mean aortic valve area 0.67 cm2. Forty-seven P (17%) underwent PPM implantation during the first 30 days after TAVI. P requiring PPM had higher prevalence of diabetes mellitus, chronic renal disease, atrial fibrillation and right bundle branch block. During a mean follow-up of 20.3 months, post-TAVI PPM was associated with similar mortality rate (29.8% vs. 25.6%, HR 1.28, 95% CI 0.72-2.29, p = 0.42) and similar cardiovascular mortality (9.8% vs. 6.4%, HR 0.72, 95% CI 0.21-2.4, p = 0.59) compared to P without PPM. There were no significant differences in HF hospitalization (4.9% vs. 2.4%, p = 0.47). Kaplan-Meier curves of total mortality and cardiovascular mortality according to the need for PPM post-TAVI were similar.  Conclusions  In P submitted to TAVI, PPM implantation is a relatively common finding, not associated with higher risk of total mortality, cardiovascular mortality or HF hospitalization in a long-term follow-up.

Abstract Funding Acknowledgements This study was supported by the János Bolyai Scholarship of the Hungarian Academy of Sciences Background A number of studies aimed to identify the predictors of periprocedural cerebral embolizations related to transcatheter aortic valve implantation (TAVI). Much less investigated is the prevalence and determinants of subacute ischaemic brain lesions that develop following TAVI. Purpose We sought to identify predictors of subacute clinically silent ischaemic brain lesions in patients following TAVI. Methods Patients were included from the Rule out Transcatheter Aortic Valve Thrombosis with Post Implantation Computed Tomography (RETORIC) prospective trial. Echocardiography and brain MRI were performed after TAVI procedure, before hospital discharge. Cardiac CT was performed 6 months later to identify subclinical leaflet thrombosis (HALT), as well as repeat brain MRI, to identify any silent ischaemic lesions that appeared since the intervention. The cognitive trajectory of patients was assessed using the Addenbrookes cognitive test (ACE), performed shortly after TAVI and at 6-month follow-up (FU). All-cause mortality data was retrieved from the National Mortality Database. Results 79 consecutive patients were included in the present analysis. 28% had known history of atrial fibrillation (AF). 33% of the cohort was treated with oral anticoagulant, of these 56% with single and 25% with dual antiplatelet therapy (DAPT). The mean CHA2DS2VASC score was 4. From discharge to the 6-month FU, 20 patients (25%) developed new silent ischaemic brain lesions on MRI. Clinically manifest stroke did not occur. On the 6-month CT, HALT was identified in 6 patients (8%). Clinical and imaging parameters, including age, body mass index, hypertension, dyslipidaemia, diabetes, smoking, statin-, OAC- and DAPT therapy, history of AF, history of stroke, echocardiographic metrics of left ventricular (ejection fraction, stroke volume index) and atrial (left atrial strain) function as well as HALT were analysed for association with ischaemic brain lesions. Of the above, only HALT showed significant association (OR:6,58; p = 0.04) with silent brain embolizations. The cognitive trajectory from discharge till 6-month FU did not differ between patients with or without ischaemic focuses (ΔACEscore: 1.0 vs. 0.1; p = NS). Over a median FU of 553 (IQR 453 – 665) days, 8 patients died; 2 with and 6 without ischaemic lesions. Kaplan-Meyer analysis showed no difference in outcome between the two groups (p = 0.68) Conclusion Subclinical leaflet thrombosis was identified as a significant predictor of subacute silent ischaemic brain lesions after TAVI. These lesions did not affect the overall cognitive performance or outcome of the patients.
