Abstract Introduction Thanks to the anticancer therapies, the life expectancy of the oncologic patients has noticeably increased, but several cardiac diseases can be observed in these patients as the result of the cardiotoxic effects. Purpose To investigate the impact of radiotherapy on the clinical and echocardiographic outcomes, in patients with severe aortic stenosis (AS) and preserved left ventricle ejection fraction (LVEF) treated with transcatheter aortic valve implantation (TAVI). Methods We recruited patients with severe AS and left ventricular ejection fraction (LVEF) ≥50‰ treated with TAVI and who received prior radiotheraphy. Patients with LVEF <50‰, treated with valve in valve, with inadequate acoustic windows or the absence of echocardiographic images pre-TAVI and after 3–6 months were excluded. Demographic, clinical and echocardiographic data were recorded. Results 102 patients were included in the present analysis. They were divided in two groups: 19 (18‰) with an oncologic history treated with previous left thoracic/mediastinal radiotherapy and 83 (82‰) patients without an oncologic history. The two groups were homogeneous in terms of demographic and clinical data, brain natriuretic peptide (BNP), echocardiographic data pre-TAVI. They only differed for a greater prevalence of mitral stenosis and calcifications in the oncologic patients versus the non-oncologics (respectively 36‰ vs. 12‰ p=0,016; 73‰ vs. 29‰ p=0,001). No differences in terms of in-hospital clinical outcomes were observed. The echocardiographic evaluation in both groups showed a significant decrease of the peak velocities and of the transprosthetic gradients. There was a higher incidence of at least moderate degree paraprosthetic leaks in the oncologic group vs. the non-oncologic one: 6 (31‰ total leaks, 37‰ leaks >2+) vs. 7 (8‰ total leaks, 12‰ leaks >2+); p=0.029. After 3–6 months, there was not a statistically significant improvement of ejection fraction (EF) in neither of the two groups but there was a statistically significant improvement of transmural, subepicardial and subendocardial longitudinal strain values in the non-oncologic group compared to pre-TAVI values, respectively −19±4 vs. −17±4 (p<0.001); −17±3 vs. −15±3 (p<0.001); −22±4 vs. −19.8±4 (p<0.001). Any statistically significant improvement was detected in the group with history of anticancer treatments between the longitudinal strain values post and pre-TAVI (−18±3‰ vs. −16±3‰; −14±3‰ vs. −20±5‰; −20 ±± 5‰ vs. −19±4‰). Conclusions Patients affected by severe AS treated with TAVI and who received received prior radiotheraphy, showed the absence of statistically significant improvement of multilayer strain values, at 3–6 months after TAVI. Oncologic patients also had a higher incidence of haemodynamically relevant paravalvular leaks after the intervention, compared to the non-oncologic patients.

Abstract Background Transcatheter aortic valve implantation (TAVI) is an effective therapeutic option for severe symptomatic aortic stenosis (AS) with intermediate/high surgical risk. Aim of this study was to examine the acute effect of TAVI in terms of pressure unloading, on left ventricular (LV) mechanics using multilayer global longitudinal strain (GLS) by 2D speckle-tracking echocardiography (ST-E). Methods A total of 44 patients (mean age 81.8 ± 2, 34% male) with severe symptomatic AS and preserved LV ejection fraction (LVEF) underwent 2D echocardiography at baseline and 5 ± 2 days after TAVI. GLS was measured from the endocardial layer (Endo-LS), epicardial layer (Epi-LS) and full thickness of myocardium before and after 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. Results By dividing patients in two groups accordingly with LV geometry assessed with regional wall thickness measurement (concentric vs eccentric hypertrophy), better values of Endo-LS were recorded at baseline, in patients with concentric hypertrophy (-12.9 ± 2 vs -11 ± 3, p = 0.048). After TAVI, a significant improvement in Endo-LS was observed, but only in patients with concentric hypertrophy (-12.9 ± 2 vs -14.2 ± 2, p = 0.003). Conclusion The improvement in LS was more prominent in the endocardium, which was evident even immediately after TAVI only in patients with concentric hypertrophy. Evaluation of multilayer strain may provide new insights into the positive effects of unloading in patients with AS and may be potentially useful to predict patients with better outcome after TAVI.

Abstract Background Relative apical sparing pattern (RASP) is thought to be associated with prognosis in patients with cardiac amyloidosis or left ventricular hypertrophy (LVH). Although almost all patients with severe aortic stenosis (AS) have LVH, little is known about the effect of transcatheter aortic valve implantation (TAVI) in patients with severe AS exhibiting a RASP. Purpose This study aimed to elucidate the effect of TAVI on left ventricular global longitudinal strain (LS; LVGLS) in patients with severe AS exhibiting a RASP. Methods Eighty-four patients who underwent transfemoral or subclavian TAVI were evaluated. They were divided into the RASP and non-RASP groups. The average apical LS divided by the sum of the average mid and basal LS values of &gt;1.0 was defined as the RASP. We analyzed the difference between pre- and post-TAVI LVGLS (ΔGLS = post-TAVI LVGLS − pre-TAVI LVGLS). Results Of the 84 patients (mean age, 84.5±3.9 years; 24 men), 15 (17.9%) exhibited a RASP. No significant difference in mean pre-TAVI LVGLS was found between the RASP and non-RASP groups (−16.6% ± 3.8% vs. −15.8% ± 3.9%). The ΔGLS in the RASP group was significantly higher than that in the non-RASP group (−0.97% ± 2.5% vs. −2.6% ± 3.0%; P&lt;0.05). Multivariate analysis revealed that relative apical longitudinal strain was an independent predictor of ΔGLS (β = 0.35, p=0.002). Conclusion Relative apical longitudinal strain was associated with LVGLS recovery. The effect of TAVI on LVGLS in patients with a RASP is inferior to that in patients without a RASP.

Abstract Introduction New onset left bundle branch block (LBBB) is the most common conduction disturbance associated with transcatheter aortic valve implantation (TAVI). It has been shown to adversely affect cardiac function and increase re-hospitalisation, although its impact on mortality remains contentious. Methods We conducted an observational cohort analysis of all TAVI procedures performed by 13 heart teams in the United Kingdom from inception of their structural programmes until 31st July 2013. The primary outcome was 1-year all-cause mortality. Secondary outcomes included left ventricular ejection fraction (LVEF) at 30 days and need for a post-TAVI permanent pacemaker (PPM). Results 1785 patients were eligible for inclusion to the study. The primary analysis cohort was composed of 1409 patients with complete electrocardiographic (ECG) data pre- and post-TAVI. Pre-existing LBBB was present in 200 (14.2%) patients. New LBBB occurred in 323 (22.9%) patients post TAVI, which resolved in 99 (7%) patients prior to discharge. A balloon-expandable device was implanted in 968 (69%) patients, whilst 421 (30%) patients received a self-expandable valve. New LBBB was observed in 120 (12.4%) and 192 (45.6%) patients receiving a balloon- or self-expandable prosthesis respectively. Overall 1-year all-cause mortality post TAVI was 18.7%. New onset LBBB was not associated with an increase in 1-year all-cause mortality (p=0.416). Factors that were associated with mortality included an increasing logistic EuroScore (p=0.05), history of previous balloon aortic valvuloplasty (p=0.001), renal impairment (p=0.003), previous myocardial infarction with pre-existing LBBB (p=0.028) and atrial fibrillation (p=0.039). Lower baseline peak and mean AV gradients were also associated with greater mortality at 1 year (p=0.001), likely reflecting underlying left ventricular dysfunction. In the majority of patients, LVEF remained unchanged following TAVI. Interestingly, the presence or absence of new onset LBBB did not affect LVEF improvement at 30 days. 10% of patients required a PPM post TAVI. Predictors of PPM included new LBBB (OR 2.6, p&lt;0.001), pre-TAVI left ventricular systolic impairment (OR 1.2, p=0.037), a self-expandable device (p&lt;0.001), and pre-existing RBBB (OR 4.0, p&lt;0.001). Conclusions These findings suggest that new onset LBBB post TAVI does not increase mortality at 1 year or adversely affect LVEF at 30 days. Funding Acknowledgement Type of funding source: None
