Web discussions on cardiovascular diseases: pre-COVID-19 evaluation and impact of the COVID-19 pandemic - Web listening analysis in the Italian population.

Background: Web discussions on health issues are becoming very relevant in the general public. In this context, little information is available regarding cardiovascular diseases, which remain the first cause of morbidity, disability and mortality worldwide. The central objective of the study was to conduct a Web listening analysis on discussions about cardiovascular diseases in Italy, comparing the data relative to the 2-year pre-COVID-19 pandemic period with those collected during the COVID-19 pandemic lockdown (March-July 2020), with quantification of conversations on cardiovascular disease and Web-based discussions and specific evaluation of COVID-19 lockdown impact.

TAVI with the ACURATE neo2 in severe bicuspid aortic valve stenosis: the Neo2 BAV Registry.

Background: The ACURATE neo2 is a contemporary transcatheter aortic valve implantation (TAVI) system approved for the treatment of severe aortic stenosis in Europe. The ACURATE neo2 has not been evaluated in bicuspid aortic valve (BAV) stenosis.

Aims: We sought to evaluate the safety and efficacy of ACURATE neo2 in patients with BAV stenosis.

The PIGTAIL paradigm for a fast and safe transfemoral transcatheter aortic valve replacement.

Transfemoral transcatheter aortic valve replacement is the preferred primary access route whenever possible. Despite advancements in expertise and delivery system profiles, complications associated with the primary femoral access still significantly affect procedural morbidity and outcomes. The current standard for accurate main access planning involves proper preprocedural evaluation guided by computed tomography.

Endovascular Low-Pass Filter: Performing Mitral Edge-to-Edge Repair With PASCAL Through an Inferior Vena Cava Filter.

We present the case of an 82-year-old man with a history of inferior vena cava filter implantation and concomitant severe mitral regurgitation requiring transcatheter edge-to-edge repair. Despite being deemed ineligible for transfemoral access as technically challenging, he successfully underwent mitral transcatheter edge-to-edge repair after crossing and dilatation of the inferior vena cava filter.

COVID-19 vaccination, implications for PET/CT image interpretation and future perspectives.

Introduction: The present paper aims to systematically review the literature on COVID-19 vaccine-related findings in patients undergoing PET/CT.

Methods: The search algorithms included the following combination of terms: "PET" OR "positron emission tomography" AND "COVID"; "PET" OR "positron emission tomography" AND "COVID" AND "vaccination"; "PET" OR "positron emission tomography" AND "COVID", AND "autoimmune".

Results: We selected 17 articles which were assessed for quality and included in the systematic analysis.

Body composition assessment: comparison of quantitative values between magnetic resonance imaging and computed tomography.

Background: The primary objective of this study was to compare measurements of skeletal muscle index (SMI), visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT) at the level of L3, on subjects who underwent computed tomography (CT) and magnetic resonance imaging (MRI) examinations within a three-month period. The secondary objective was to compare the automatic and semi-automatic quantifications of the same values for CT images.

Methods: Among subjects who underwent CT and MRI at our Institution between 2011 and 2020, exclusion criteria were: presence of extensive artifacts; images not including the whole waist circumference; CT acquired with low-dose technique and lack of non-contrast images.

Methodological framework for radiomics applications in Hodgkin's lymphoma.

Background: According to published data, radiomics features differ between lesions of refractory/relapsing HL patients from those of long-term responders. However, several methodological aspects have not been elucidated yet.

Purpose: The study aimed at setting up a methodological framework in radiomics applications in Hodgkin's lymphoma (HL), especially at (a) developing a novel feature selection approach, (b) evaluating radiomic intra-patient lesions' similarity, and (c) classifying relapsing refractory (R/R) vs non-(R/R) patients.
