The pandemic changed the type of patients. The concept of "patient at the center" became concrete. The execution of simple consultancy was overcome to create effective collaboration and fruitful exchanges between specialists. The "Heart Team" model is on increasing affirmation. The TEAM-BASED approach in the cardiology field is successfully used in patients suffering from ischemic heart disease and valvulopathies for the choice of possible treatments. Degenerative type Sao is the most frequent valvulopathy among the valvulopathies in Western countries and its incidence is correlated with age. In high-risk patients, percutaneous valve replacement (transcatheter aortic valve implantation) is the most valid therapeutic option. The implantation of biological prostheses raises the problem of both degeneration and dysfunction of the prosthesis itself over time in subjects of advanced age and with comorbidities. In this scenario, valve-in-valve (VinV) is a valid therapeutic alternative in high-risk patients. A clinical case of aortic prosthetic degeneration, as an outcome of endocarditis, treated with VinV is presented. The therapeutic decision was made by an "Electronic Heart Team" which represents a further evolution of the treatment pathways and reduces the distance between the specialists in "Hub" Centers and the "Spoke" center., Competing Interests: There are no conflicts of interest., (Copyright: © 2024 Journal of Cardiovascular Echography.)

Age is associated with an enhanced low density lipoprotein (LDL) oxidation and atherosclerosis, thus, subjects over 80 years without cardiovascular disease provide a model to investigate the protective factors against atherosclerosis. Serum paraoxonase (PON1), an high density lipoprotein (HDL)-bound enzyme, prevents LDL oxidation. The aim of the present study was to evaluate the contribution of the PON1 promoter T(-107)C and coding region Gln192Arg (Q192R) and Leu55Met (L55M) polymorphisms to the resistance to develop cardiovascular events in Sicilian healthy octogenarians. Distribution of PON1 genotypes and activity, and biochemical parameters, were compared between 100 octogenarians and 200 adults. Individuals in the elderly group displayed significant higher levels of HDL-C (P < 0.001) and PON1 activity (P < 0.001). The analysis of PON1 genotypes distribution showed an higher percentage of (-107)CC among octogenarians compared with controls. A significant difference among T(-107)C genotypes respect to PON1 activity and HDL-C levels occurred in both groups. The CC genotype was associated with higher PON1 activity and HDL levels compared to the TT genotypes. In conclusion, our results provide a strong evidence that in healthy Sicilians ageing may be characterized by a low frequency of PON1 (-107)T 'risk' allele and by an high frequency of favourable genotypes such as (-107)CC, influencing PON1 activity and HDL-C levels.
