Abstract Background Since the first-in-man transcatheter aortic valve implantation (TAVI) performed in 2002, the number of procedures has dramatically increased. However, long-term data regarding outcome and valve durability remain poor. Purpose We aimed to evaluate the evolution of 30-day outcomes over years and long-term mortality and valve durability after TAVI. Methods All consecutive patients presenting with severe symptomatic aortic stenosis treated by TAVI in our center were included prospectively. Clinical and echocardiographic follow-up was performed at 30 days and annually thereafter. Survival curves were constructed using Kaplan-Meier analysis. We also evaluated valve durability according to the European standardized definition of structural valve deterioration. Results Between 2002 and 2018, 1530 consecutive patients underwent TAVI including 1285 (84.0%) patients via a femoral approach. A balloon-expandable transcatheter heart valve was predominantly used (1421 patients; 92.9%). The annual transfemoral approach rate increased progressively to reach 93.3%. Age of patients remained stable over time with a global mean age of 83.7±6.5 years old. Logistic EuroSCORE decreased from 49.2±8.2% to 14.3±8.6% (p<0.0001). Thirty-day mortality dramatically decreased below 3% since 2015 and was 0% in 2018. Similarly, major vascular complications decreased from 50.0% in the first year to less than 1% since 2017 (p=0.001). The length of hospital-stay progressively shortened up to a median of 2 days in 2018. The Kaplan-Meier survival estimation was 82.3%, 60.3%, 33.0%; 11.7% and 8.9% respectively at 1, 3, 5, 8 and 10 years. On long-term follow-up the mean aortic gradient remained unchanged (Figure), and only five patients presented a severe prosthetic valve deterioration. Among them, four patients successfully benefited from a valve in valve TAVI procedure. The competing risk analysis at 10 years estimates risk for severe and moderate-or-severe valve deterioration of 1.9±0.9% and 4.3±1.3% respectively. TEE mean transaortic gradient Conclusions Long-term (up to 10 years) follow-up of our large pioneer series of patients treated by TAVI shows a dramatic improvement of outcomes and no warning signs of valve deterioration suggesting very encouraging valve durability, using predominantly, a balloon expandable prosthesis. Further studies are warranted to study valve durability after TAVI before extension to lower risk patients.

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 &lt;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 Background The prevalence of cardiac amyloidosis (CA) and aortic stenosis (AS) both increase with age. Transcatheter aortic valve implantation (TAVI) expands the number of patients (P) eligible for treatment of AS, emphasizing the need to understand the prevalence of CA in AS and its prognostic associations. Echocardiography with speckle tracking has emerged as a useful method to enhance the clinical suspicion and to provide prognostic information. Purpose To estimate the prevalence of CA in P with severe AS referred for TAVI and to evaluate the impact of concomitant CA in prognosis. Methods 94 consecutive AS P who underwent TAVI with maximum left ventricular wall thickness (LVWT)&gt;12 mm were retrospectively identified. Clinical data, pre TAVI echocardiographic parameters and follow up (FU) data regarding all-cause mortality and MACE (including all-cause mortality, admission for heart failure, pacemaker implantation and stroke) were analysed. We registered apical sparing pattern in bull’s eye plots (ASPB), calculated relative apical longitudinal strain formula (RALS) [average apical LS/(average basal LS + mid-LS)] and ejection fraction/global longitudinal strain (EF/GLS) ratio. Results Mean age was 82.2 ± 5.8 years (Y), with 43 men (45.7%). 27.7% were in NYHA functional class II, 64.9% in functional class III and 7.4% in functional class IV. Median EF was 57 ± 15% and 26.6% presented EF &lt; 50%. Suspected CA evaluated by ASPB was found in 39 P (41.5%) and RALS &gt; 1 was identified in 22 P (23.4%). An EF/GLS ratio &gt; 4.1 was obtained in 53 P (56.4%). Over a median follow-up of 13.4 ± 25.8 months, 28 deaths (29.8%) and 31 MACEs (33.0%) occurred. The presence of ASPB was associated with increased all-cause mortality (33.3% vs. 5.6%, p = 0.002), new bundle branch block and indication for pacemaker implantation (46.2% vs 37.0%, p = 0.05) and MACE (48.7% vs 22.2%, p = 0.01). All-cause mortality was also higher in P with RALS (31.8% vs. 12.5%, p = 0.04). P with GLS&gt;-14.8% and ASPB had significantly worse prognosis regarding all-cause mortality (p = 0.003) and MACE (p = 0.007). Kaplan–Meier survival analysis showed that survival was significantly worse for P with ASPB (log-rank 0.002). With multivariate Cox regression analysis, ASPB was independently associated with all-cause mortality (HR = 4.49, p = 0.039). Conclusions Suspected CA appears prevalent among patients with AS and associates with all-cause mortality. The importance of screening for CA in older AS patients and optimal treatment strategies in those with CA warrant further investigation, especially in the era of transcatheter aortic valve implantation.

Abstract Background With the growing indications of transcatheter aortic valve implantation (TAVI) worldwide and among lower risk patients, valve durability has become a crucial issue. Purpose To assess mid and long-term evolution of different generations of percutaneous balloon-expandable prostheses, predictive factors of valve deterioration and its correlation with long-term mortality. Methods All consecutive patients undergoing TAVI for severe aortic stenosis with balloon-expandable prosthesis between 2009 and 2014 and with a minimum follow-up of one-year were included in this monocentric prospective study. All echocardiograms were reviewed by two independent experts. Clinical events were defined according to the Valve Academic Research Consortium criteria. Valve deterioration was defined according to the 2017 EAPCI-ESC-EACTS international consensus statement at the longest follow-up. Results A total of 160 patients were included with a median follow-up of 3.4 years [1.5–4.9] and a maximum of 8 years. Patients were mostly implanted with the first generation Sapien XT valve (n=138, 86.2%). Median age was 85 [79–86] years, with 42.5% of women and a median logistic Euro-SCORE of 14.2% [10.6–23.2]. Immediately after TAVI, mean aortic gradient decreased dramatically from 51±12mmHg to 9±2.6mmHg (p<0.0001) and remained overall stable with a mean gradient of 12±1mmHg at 8 years. Valve deterioration occurred in 5.6% (n=9) of patients, of which 3.7% (n=6) with severe deterioration. Moderate or severe peri-prosthetic aortic regurgitation was observed in 2.5% (n=4) of patients. The eight-year survival rate was 12.9%. During follow-up, hospitalization for acute heart failure was required for 23.7% (n=38) of patients, a myocardial infarction or a stroke occurred respectively among 1.9% (n=3) and 5% (n=8) of patients. After multivariate analysis, size or generation of valves were not independent predictive factors of valve deterioration. Evolution of mean aortic gradient Conclusions After a maximal 8-year follow-up, valve deterioration after balloon-expandable TAVI is very low. In this high-risk population, TAVI seems to be a safe and durable alternative to surgery in severe aortic stenosis regardless of prosthesis generation. Acknowledgement/Funding Edwards Lifesciences
