Background: Sutureless aortic bioprostheses are increasingly being used to provide shorter cross-clamp time and facilitate minimally invasive aortic valve replacement. As the use of sutureless valves has increased over the past decade, we begin to encounter their degeneration. We describe clinical outcomes and technical aspects in patients with degenerated sutureless Perceval (CorCym, Italy) aortic bioprosthesis treated with valve-in-valve transcatheter aortic valve replacement (VIV-TAVR).

Frailty is highly common in older patients (pts) undergoing transcatheter aortic valve replacement (TAVR), and it is associated with poor outcomes. The selection of patients who can benefit from this procedure is necessary and challenging. The aim of the present study is to evaluate outcomes in older severe aortic valve stenosis (AS) pts, selected by a multidisciplinary approach for surgical, clinical, and geriatric risk and referred to treatment, according to frailty levels.

The impact of climate change on both terrestrial and aquatic ecosystems tends to become more progressively pronounced and devastating over the years. The sector of aquaculture is severely affected by natural abiotic factors, on account of climate change, that lead to various undesirable phenomena, including aquatic species mortalities and decreased productivity owing to oxidative and thermal stress of the reared organisms. Novel innovative technologies, such as aquaponics that are based on the co-cultivation of freshwater fish with plants in a sustainable manner under the context of controlled abiotic factors, represent a promising tool for mitigating the effect of climate change on reared fish.

An 88-year-old man was referred to transcatheter aortic valve replacement for severe symptomatic aortic stenosis. Edwards 26-mm Sapien bioprosthetic valve (Sapien) implantation was planned after accurate computed tomography-based procedure planning. When the valve was released, the inflation pressure decreased rapidly due to the balloon bursting.
