Diabetes, fasting plasma glucose and hypertension, but not the metabolic syndrome, were associated with severity of coronary angiographic findings in these women.

Aims The aim of this study was to examine the prevalence of amyloid transthyretin (ATTR) cardiac amyloidosis in patients 1–2 years after trans‐catheter aortic valve replacement (TAVR) and to assess their clinical and echocardiographic outcome and long‐term survival. Methods and results We enrolled 88 patients, mean age 81 years, 534 (390–711) days after TAVR. Patients underwent a Tc99m‐PYP scintigraphy for the diagnosis of ATTR cardiac amyloidosis. Eleven (12.5%) participants were diagnosed with ATTR cardiac amyloidosis. Eighty eight per cent of patients without amyloidosis were in New York Heart Association Classes 1–2 after TAVR, compared with 64% patients with ATTR cardiac amyloidosis (P = 0.022). There were no differences in left ventricular (LV) ejection fraction (P = 0.69) between patients with and without ATTR cardiac amyloidosis at enrolment. The LV mass index and pulmonary artery pressure were significantly higher in patients with ATTR cardiac amyloidosis (P = 0.046 and P = 0.002, respectively). Global longitudinal strain and myocardial work efficiency were significantly lower in patients with ATTR cardiac amyloidosis (P = 0.031 and P = 0.048, respectively). We assessed changes in echocardiographic data, from the time of TAVR to enrolment, and as expected, there was a significant decrease in aortic valve gradient in both groups. There was a significant reduction in LV mass and LV mass index and improvement in basal segment LV strain in the ATTR cardiac amyloidosis negative group (P = 0.045, P = 0.046 and 0.023, respectively). However, in the ATTR cardiac amyloidosis group the change in LV mass and LV mass index and LV basal strain values was not significant (P = 0.24, P = 0.13 and P = 0.35, respectively). The were no significant changes in other echocardiographic parameters in both groups. The patients were followed for 1150 (1086–1221) days after enrolment. Twenty seven patients had at least one cardiac hospitalization during of follow up, of them seven were with ATTR cardiac amyloidosis and 20 patients without amyloidosis (P = 0.017). Eighteen patients (20%) died during follow up; 12 (14%) patients died due to cardiac causes. There was no difference in all‐cause and cardiac mortality between patients with and without ATTR cardiac amyloidosis (P = 0.6 and P = 0.53, respectively). Conclusions The long‐term survival after TAVR is not significantly affected by the presence of ATTR cardiac amyloidosis. However, the clinical course of these patients and the LV hemodynamic improvement is less favourable. This hypothesis‐generating study suggests screening for ATTR cardiac amyloidosis in patients who underwent TAVR and have limited clinical or echocardiographic improvement, because they may potentially improve with new therapies for ATTR cardiac amyolidosis.

Background: Calcific aortic stenosis (AS) is a progressive disease, and once moderate AS is present, the likelihood of symptom onset within 5 years is significant. The aim of this study was to determine the incremental value of global longitudinal strain (GLS) and basal longitudinal strain (BLS) at rest and during exercise on outcomes among asymptomatic patients' with moderate and severe AS. Methods: Seventy-five patients with isolated, asymptomatic AS and preserved left ventricular function were retrospectively enrolled and underwent symptom-limited exercise echocardiography. Clinical and echocardiographic data, including GLS and BLS at rest and during exercise, were assessed. Occurrence of ASrelated cardiovascular events was recorded. Results: The mean age was 71 6 10 years, and 63% were men. The mean aortic valve gradient was 30 6 11 mm Hg, and the mean aortic valve area was 0.98 6 0.21 cm 2. Resting GLS and BLS were À16.5 6 4% and À16.9 6 3.6%, respectively. Exercise stress test results were positive in 27 patients (36%). Mean exercise GLS was À17.8 6 3.5%, and mean exercise BLS was À17.9 6 4%. During mean follow-up of 34.5 6 3.5 months, cardiovascular events were observed in 45 patients. In multivariate analysis, aortic valve mean gradient (HR, 1.073; 95% CI, 1.032-1.115; P < .001) and peak exercise BLS (HR, 1.177; 95% CI, 1.07-1.295; P = .001) were associated with cardiac events during follow-up. Conclusions: Reduced exercise BLS is associated with future cardiovascular events in patients' with asymptomatic AS, independently of clinical factors and conventional echocardiographic parameters. Detection of postexercise myocardial dysfunction in patients with asymptomatic AS with preserved left ventricular function can aid in risk assessment of these patients.

Objective Transcatheter aortic valve implantation (TAVI) provokes early injury response, represented in part by dynamic changes in the inflammatory markers. The association of self-expanding valves (SEVs) and balloon-expandable valves (BEVs) with the consequent inflammatory response remains uncertain. Materials and methods Patients with severe symptomatic aortic stenosis who underwent transfemoral TAVI: SEVs or BEVs, from January 2010 to December 2019 were enrolled. Whole white blood cells (WBC) and subpopulation dynamics as well the neutrophil to lymphocyte ratio (NLR) were evaluated. Results Three-hundred seventy consecutive patients (mean age 81.75 ± 6.8 years, 199 women’s) were enrolled. In the entire population, significant kinetic changes in the WBC response (p <0.0001) between admission and first 24 hours post procedure, with a significant increase in total WBC (7.46 ± 2.26 to 10.08 ± 3.55) and absolute neutrophil count (4.97 ± 2.06 to 8.19 ± 3.43), NL ratio (3.72 ± 2.8 to 9.76 ± 7.29), and a meaningful decrease in absolute lymphocytes count (1.67 ± 1.1 to 1.1 ± 0.76). When compared between the types of valves, SEVs were associated with a more pronounced inflammatory response than BEVs, with total WBC (10.44 ± 3.86 vs. 9.45 ± 3.19) neutrophils (8.56 ± 3.75 vs. 7.55 ± 3.06) with p 0.016 and 0.012 respectively. Conclusion This is the first description of a differential inflammatory response between the two leading delivery systems. SEV appears to trigger a more robust inflammatory response as compared to BEV. Clinical studies are warranted to assess the long term effect of our findings.

Background: Transcatheter aortic valve implantation related thrombocytopenia (TAVI-rTP) is an inevitable phenomenon. However, no study has been performed on TAVI-rTP in the current setting of extended clinical indications combined with technology improvements.Methods: Patients with severe symptomatic aortic stenosis who underwent transfemoral TAVI, from January 2016 to December 2019 were enrolled.Results: Two-hundred and one consecutive patients (mean age 81.1 ± 7.1 years, 96 men) enrolled. Platelet count was recorded before and after aortic valve implantation. Dropped platelet count (DPC) occurred in all but 11 patients who were included.Two groups were created: DPC <30 and DPC ≥30%. DPC was compared with inhospital major adverse cardiovascular events. The mean DPC was 26 ± 14%. We found that 67 patients (33.3%) had DPC of more or equal to 30%. In the univariable analysis, the time of the procedure (94.4 ± 32.7 vs 79.4 ± 21.9, p = .002), the amount of the contrast used (125.4 ± 55.4 vs 108.4 ± 44.1, p = .02) and the residual AV gradient (13.3 ± 7.2 vs 14.7, p = .05) were related to a DCP ≥30%. A DPC ≥30% was associated with increased risk of life-threatening/major bleeding (11.9% vs 1.5%, p = .001), major vascular complications (16.4% vs 5.2% p = .009) and death (3.0% vs 0%, p = .044) at 30 days. After multivariable analysis, the factors associated with a higher DPC were time and contrast. Conclusion:Contemporary TAVI-rTP in this cohort of patients continues to be a common phenomenon but severe thrombocytopenia is less frequent. Patients developing a DPC ≥30% are associated with poor outcomes at 30 days.
