Abstract Background Myocardial Strain evaluation helps to assess the efficacy of therapeutic interventions and to predict the prognosis and clinical outcomes. The aim of the present study was to assess whether Multilayer Global longitudinal Strain (GLS) can be useful in estimation of left ventricle (LV) function in patients with severe symptomatic aortic stenosis (AS) who have undergone transcatheter aortic valve implantation (TAVI). Methods 35 patients with severe AS who successfully underwent TAVI, were enrolled in the study. GLS was measured from the endocardial layer (Endo-LS), epicardial layer (Epi-LS) and full thickness of myocardium before the procedure. Analysis included other parameters such as age, sex, LV volumes and ejection fraction (LVEF), type of prosthesis implanted, right ventricular (RV) dimension and function. Occurrence of cardiovascular (CV) events (rehospitalization for HF or CV death) were collected after 24 months follow-up.Results: CV events occurred in 7 patients (20%). Patients were divided in two groups accordingly with CV events occurrence. No differences in baseline, demographic, echocardiographic and procedural characteristics were found. Patients who developed CV events had a more impaired pre-procedural GLS (-10.2 ± 2.4% vs -12.6 ± 2.2%, p = 0.029), mostly due to his subendocardial layer (Endo-LS -10.8 ± 2 vs -13.9 ± 2, p = 0.003). Moreover, by ROC curve analysis, a cut-off value of -12.4% of endo LS was associated with CV events (sensitivity of 83% and specificity of 65 %, AUC 0.8, p = 0.024), with a log-rank p value assessed by survival analysis of 0.044. Conclusion Multilayer GLS analysis could provide additional information for prognosis stratification in patients with severe symptomatic AS before TAVI, above and beyond assessment of LVEF alone.

Background: Prior studies have proven the safety and efficacy of transcatheter aortic valve implantation (TAVI) in patients with reduced left ventricular (LV) function. This study’s aim was to investigate periprocedural inflammatory responses after TAVI. Methods: Patients with severe symptomatic aortic stenosis and reduced LV function who underwent transfemoral TAVI were enrolled. A paired-matched analysis (1:2 ratio) was performed using patients with preserved LV function. Whole white blood cells (WBC) and subpopulation dynamics as well as the neutrophil to lymphocyte ratio (NLR) were evaluated at different times. Results: A total of 156 patients were enrolled, including 52 patients with LVEF < 40% 35.00 [30.00, 39.25] and 104 with LVEF > 50% 55.00 [53.75, 60.0], p < 0.001. Baseline NLR in the reduced LV function group was significantly higher compared to the preserved LV function group, 2.85 [2.07, 4.78] vs. 3.90 [2.67, 5.26], p < 0.04. After a six-month follow-up, the inflammatory profile was found to be similar in the two groups, NLR 2.94 [2.01, 388] vs. 3.30 [2.06, 5.35], p = 0.288. No significant mortality differences between the two groups were observed in the long-term outcome. Conclusions: TAVI for severe symptomatic aortic stenosis, with reduced LV function, was associated with an improvement in the inflammatory profile that may account for some of the observable benefits of the procedure in this subset of patients.

The present study aimed to analyze sleep quality and quality of Life (QoL) in patients undergoing Transcatheter Aortic Valve Implantation (TAVI). It was conducted at the Interventional Cardiology Unit of the Department of Cardiac, Thoracic, Vascular Sciences and Public Health of the University of Padova on 27 adult patients who underwent TAVI via the transfemoral approach. Patients completed two validated instruments, i.e., the Pittsburgh Sleep Quality Index (PSQI) and the EuroQoL (EQ-5D-5L), on the day of discharge and one month after the hospital discharge. Twenty-seven patients were enrolled with a severe aortic stenosis diagnosis, treated with transfemoral TAVI procedure. The study population included seventeen poor sleepers and ten good sleepers with a median age of 81.92 years overall. The global PSQI evaluation revealed a small significant improvement at follow-up (p-value 0.007). Small positive changes were detected in the Self-care and Usual activity domains of the EQ-5D-5L and the EQ-VAS. No correlation was detected between EQ-5D-5L and sleep quality. The present study confirms the importance of sleep quality monitoring in patients who undergo TAVI procedure for aortic stenosis treatment.

Abstract Aims  Myocardial fibrosis (MF) might represent a key player in pathophysiology of heart failure in aortic stenosis (AS). We aimed to assess its impact on left ventricular (LV) remodelling, recovery, and mortality after transcatheter aortic valve implantation (TAVI) in different AS subtypes. Methods and results  One hundred patients with severe AS were prospectively characterized clinically and echocardiographically at baseline (BL), 6 months, 1 year, and 2 years following TAVI. Left ventricular biopsies were harvested after valve deployment. Myocardial fibrosis was assessed after Masson’s trichrome staining, and fibrotic area was calculated as percentage of total tissue area. Patients were stratified according to MF above (MF+) or below (MF−) median percentage MF (≥11% or &lt;11%). Myocardial fibrosis burden differed significantly between AS subtypes, with highest levels in low ejection fraction (EF), low-gradient AS and lowest levels in normal EF, high-gradient AS (29.5 ± 26.4% vs. 13.5 ± 16.1%, P = 0.003). In the entire cohort, MF+ was significantly associated with poorer LV function, higher extent of pathological LV remodelling, and more pronounced clinical heart failure at BL. After TAVI, MF+ was associated with a delay in normalization of LV geometry and function but not per se with absence of reverse remodelling and clinical improvement. However, 22 patients died during follow-up (mean, 11 months), and 14 deaths were classified as cardiovascular (CV) (n = 9 arrhythmia-associated). Importantly, 13 of 14 CV deaths occurred in MF+ patients (CV mortality 26.5% in MF+ vs. 2% in MF− patients, P = 0.0003). Multivariate analysis identified MF+ as independent predictor of CV mortality [hazard ratio (HR) 27.4 (2.0–369), P = 0.01]. Conclusion  Histological MF is associated with AS-related pathological LV remodelling and independently predicts CV mortality after TAVI.

Transcatheter aortic valve implantation (TAVI) is relatively contraindicated in the bicuspid aortic valve, and to our knowledge has not been tried where the true native annulus is of a size far in excess of current device capabilities. We present here a case of a successful emergency TAVI of a 73-year-old previously healthy man, who presented with cardiogenic shock, ventricular tachycardia storm and severe left ventricular dysfunction because of the underlying critical bicuspid aortic stenosis with aortic annulus area of 991.9 mm2 and associated moderate aortic incompetence (the Society of Thoracic Surgeons (STS) risk score; score mortality of 40.9%). Despite the critical condition of the patient and technically challenging anatomy, successful TAVI was performed and the patient remains well with near-normal left ventricle (LV) function at 6 months follow-up.
