Abstract Background and Aims Transcatheter aortic valve implantation (TAVI) is indicated for the treatment of patients with severe aortic stenosis with a high surgical risk that are rejected for surgical valve placement. The aim of this study is to evaluate the effect of TAVI on long-term kidney function in stage 3-4 chronic kidney disease (CKD) patients. Method We performed a single-center retrospective observational study of 529 consecutive patients that underwent TAVI between August 2007 and January 2018. We included patients with stage 3 or 4 CKD, with at least two stable measurements of glomerular filtration rate during the three months before TAVI. We excluded patients that presented with an acute kidney injury during the three months that preceded TAVI. Results 165 patients (31.3%) of the patients who underwent TAVI had a stable stage 3 or 4 CKD before implantation. Their mean age was 83.61 ±5.08 years, BMI of 27.79 ± 4.54 kg/m2, baseline serum creatinine of 1.62 ± 0.49 mg/dl for an eGFR measured by MDRD-4 of 40.19 ± 10.79 ml/min, EuroScore-II of 6 (IQR 4-8). 42 patients (28.6%) had a post-procedural acute kidney injury (AKI), 2 of them required temporary renal replacement therapy and 30 patients (71.4%) recovered to their baseline kidney function. Mean contrast media administered was 162.0 ±77.8 ml. Mean serum creatinine decreased from 1.64 ± 0.51 mg/dl to 1.46 ± 0.52 ml/min after 1 year of follow-up (p=0.032). Only 2.4% of patients showed a >50% increase in serum creatinine after 1 year. Median follow-up was 3.8 years (IQR 2.3-5.7 years) during which time no patient progressed to end-stage kidney disease. 33.3 % of patients died during follow-up, with a one-year survival rate of 87% and two-year survival of 82%. Post-interventional major bleeding (14.6 vs 5.8%, p<0.001) and the need for post-interventional pacemaker implantation (25 vs 13.3%, p<0,001)were the only risk factors associated with the development of AKI. Contrast volume was not associated with the development of AKI. AKI was associated with an increased in-hospital stay (13.2 vs 7.4 days, p<0.001), but was not associated with either a reduced kidney function at end of follow-up or an increased mortality (Log-rank X2=1.72, p=0,578). Conclusion Despite the high incidence of post-interventional AKI after TAVI, our study did not show an association between AKI and increased mortality or reduced renal survival. In most cases after AKI patients recovered to their baseline kidney function. There is an improvement in kidney function after one year of treatment of severe aortic stenosis with TAVI in patients with CKD Stage 3-4.

Background: Patients with severe aortic stenosis frequently have coexisting coronary artery disease. Invasive hyperemic and nonhyperemic pressure indices are used to assess coronary artery disease severity but have not been evaluated in the context of severe aortic stenosis. Methods: We compared lesion reclassification rates of fractional flow reserve (FFR) and resting full-cycle ratio (RFR) measured before and 6 months after transcatheter aortic valve implantation using the conventional clinical cutoffs of ≤0.80 for FFR and ≤0.89 for RFR. This was a substudy of the ongoing NOTION-3 trial (Third Nordic Aortic Valve Intervention). Two-dimensional quantitative coronary analysis was used to assess changes in angiographic lesion severity. Results: Forty patients were included contributing 50 lesions in which FFR was measured. In 32 patients (36 lesions), RFR was also measured. There was no significant change in diameter stenosis from baseline to follow-up, 49.8% (42.9%–57.1%) versus 52.3% (43.2%–57.8%), P =0.50. RFR improved significantly from 0.88 (0.83%–0.93) at baseline to 0.92 (0.83–0.95) at follow-up, P =0.003, whereas FFR remained unchanged, 0.84 (0.81–0.89) versus 0.86 (0.78–0.90), P =0.72. At baseline, 11 out of 50 (22%) lesions were FFR-positive, whereas 15 out of 50 (30%) were positive at follow-up, P =0.219. Corresponding numbers for RFR were 23 out of 36 (64%) at baseline and 12 out of 36 (33%) at follow-up, P =0.003. Conclusions: In patients with severe aortic stenosis, physiological assessment of coronary lesions with FFR before transcatheter aortic valve implantation leads to lower reclassification rate at 6-month follow-up, compared with RFR.

Abstract Aims Transcatheter aortic valve implantation (TAVI) has become a first-line treatment for most patients with severe aortic stenosis (AS) at intermediate/high surgical risk, resulting in significant improvement of clinical outcome. However, whether ventricular arrhythmias (VAs) or cardiac autonomic dysfunction influence outcome and whether TAVI has any effects on VAs and cardiac autonomic function is unknown. Thus, this study was aimed to investigate: I1) whether VAs and autonomic dysfunction [as assessed by heart rate variability (HRV)] are associated with clinical outcome and (2) the effects of TAVI on VAs and HRV, in patients with severe AS. Methods and results We studied 71 consecutive patients with severe aortic stenosis, admitted to our department of Cardiovascular Medicine to undergo TAVI. Patients with previous cardiac surgery, percutaneous coronary revascularization, acute coronary syndrome, and other significant heart valve disease or relevant comorbidities were excluded. The day before TAVI all patients underwent transthoracic Doppler echocardiography (TTDE), including global longitudinal strain (GLS) assessment, and 24-h ECG Holter monitoring (HM), to assess VA burden and HRV. A clinical follow-up was performed at 6 months from discharge. Furthermore, TTDE and 24-h HM were performed at follow-up in 38 (54.5%) and 29 (40.8%) patients, respectively. The primary endpoint was the occurrence of major clinical events (MACE), that include death, hospitalization for cardiac causes, pacemaker implantation, myocardial infarction, or stroke. Of 71 patients (48 female, mean age 80.5 ± 6.5 years) enrolled in the study, a 6-month clinical follow-up could be performed in 54 (76%). MACE occurred in 21 patients (38.9%), 8 of whom (14.8%) had hospitalization for heart failure, 13 (24%) required pacemaker implantation, and 3 had stroke (5.6%). Compared to baseline, at follow-up the mean aortic valve gradient (50.6 ± 11.4 vs. 8.38 ± 3.23 mmHg, P < 0.001), left ventricle (LV) mass index (131.4 ± 38.9 vs. 112.9 ± 28.3 g, P = 0.007), pulmonary artery systolic pressure (37.3 ± 5.8 vs. 30.2 ± 9.8 mmHg; P < 0.001), and the ratio of Doppler transmitral early filling velocity to tissue-Doppler early diastolic mitral annular velocity (E/e′) (16 ± 5.3 vs. 13.2 ± 4.7 P < 0.001) were significantly reduced. In contrast no changes were observed in VAs. The number of premature ventricular complexes (PVCs) at HM was indeed 1062 ± 3833 vs. 1206 ± 3322 at follow-up and baseline, respectively (P = 0.11). Furthermore, PVCs >10 per hour were detected in a higher number of patients at 6-month follow-up, compared to baseline (23.8% vs. 45.2%; P = 0.022). No significant differences were detected in most time-domain and frequency-domain HRV parameters. Unexpectedly, SDNNi (62.8 ± 19.1 vs. 41.9 ± 16.5; P = 0.008), RMSSD (54.6 ± 36.6 vs. 30.1 ± 17.9; P = 0.024) and VLF (56.4 ± 49.6 vs. 29 ± 12.7; P = 0.028) were found to be significantly higher at follow-up compared to baseline. Conclusions Our data show that, in patients with severe AS, TAVI does not seem to have significant effects on VA burden, despite echocardiographic and clinical improvement. Similarly, our data failed to show significant improvement of sympatho-vagal balance at follow-up compared to baseline in these patients.

Abstract Introduction Infective endocarditis (IE) is a potentially fatal complication of prosthetic valve replacement and increasing use of transcatheter aortic valve implantation (TAVI) has resulted in a new elderly and frail population at increased risk of IE. The incidence of IE after TAVI and factors that influence the risk and subsequent outcome are relatively unknown. Purpose To describe the incidence, predictors, echocardiographic findings, microbiology and clinical outcomes of IE following TAVI in the United Kingdom (UK). Methods Patients who underwent TAVI between Jan 1 2007 and Dec 31 2016 were identified from the UK TAVI database held by the National Institute for Cardiovascular Outcomes Research. For this cohort, all hospital admissions with a primary diagnosis of IE were identified by linkage with the NHS Hospital Episode Statistics Admitted Patient Care database, or by contact with regional TAVI centres. Additional information concerning clinical presentation, imaging findings, microbiology, management and patient outcome were obtained where possible from the treating physician. Results A total of 16,014 patients underwent TAVI, of whom 157 developed IE over a median follow-up of 23.8 (IQR 7.8–52.4) months - an overall incidence of 0.98% (0.53% at one year post-TAVI). The mean age of patients with IE was 79.2±7.8 years, and 69% were male. The median time to IE following TAVI was 10.0 (IQR 4.0–22.3) months. On multivariate analysis, IE was significantly more common in men (HR 2.05, 95% CI 1.35–3.11, p=0.001) and in patients receiving mechanically-expandable (HR 2.15, 95% CI 1.16–4.01, p=0.015) or balloon-expandable valves (HR 1.60, 95% CI 1.01–2.52, p=0.045) compared to self-expanding valves. IE was also more common in those with an aortic valve peak gradient following TAVI deployment greater than median (HR 1.81, 95% CI 1.23–2.67, p=0.003). The most common presenting symptom was fever (present in 67.1%). The most frequent causal organisms were enterococci (25.9%), followed by oral streptococci (16.4%) and Staphylococcus aureus (11.8%). Transoesophageal echocardiography demonstrated vegetations in 72.5% of patients, most commonly on the TAVI valve leaflets (58.8%). Only 8.24% of patients underwent surgical valve intervention. Survival rates at hospital discharge and one year follow up were 61.4% and 54.4%, respectively. Specific factors associated with one-year mortality were cardiogenic shock (HR 4.6, 95% CI 2.1–10.3, p=0.0002), septic shock (HR 3.4, 95% CI 1.4–8.3, p=0.006) and stroke (HR 4.9, 95% CI 1.46–16.7, p=0.01). Conclusions The incidence of IE one year after TAVI was 0.53% and greater risk was associated with male sex, mechanically-expandable and balloon-expandable valves, and elevated post-deployment valve gradient. Enterococci were the most common causative organism. Overall survival at one year was 54.4%, with adverse outcome predicted by cardiogenic shock, septic shock or stroke.

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
