Introduction: Due to the selective criteria and short-term follow-up of previous transcatheter aortic valve implantation (TAVI) trials, the coronary revascularization incidence after TAVI has been difficult to determine. This study investigated the epidemiology of coronary revascularization after surgical aortic valve replacement (SAVR) and TAVI in patients with severe aortic valve stenosis (AS), with and without coronary artery disease (CAD), in a mid-term follow-up, single-center, real-world setting.
Methods: Between 2010 to 2020, 1486 patients with AS underwent SAVR or TAVI with balloon-expandable Edwards transcatheter heart valves (THVs). Using hospital discharge records, we could estimate for each patient resident in Emilia Romagna the rate of ischemic events treated with percutaneous coronary intervention (PCI). A subgroup without CAD was also analyzed.
Results: The 5-year overall survival was 78.2%. Freedom from PCI after AVR and TAVI at 5 years was 96.9% and 96.9%, respectively, with previous PCI as a predictor (HR 4.86, 95% CI 2.57-9.21 < 0.001). The freedom from PCI curves were not significantly different.
Conclusions: Notwithstanding the aged population, the revascularization incidence was only 2.4%, requiring further evaluation even in younger patients with longer follow-up. Despite the profile frame raise due to the evolution of Edwards balloon-expandable THVs, PCI or coronarography feasibility were not compromised in our population.

Computed tomography (CT)-derived Epicardial Adipose Tissue (EAT) is linked to cardiovascular disease outcomes. However, its role in patients undergoing Transcatheter Aortic Valve Replacement (TAVR) and the interplay with aortic stenosis (AS) cardiac damage (CD) remains unexplored. We aim to investigate the relationship between EAT characteristics, AS CD, and all-cause mortality.

Background: Untreated severe heart valve disease (HVD) is associated with premature mortality. Research shows low population awareness of when to seek assessment and low focus on cardiac auscultation by physicians in primary care settings. We studied contemporary public knowledge of HVD and assessment by their general practitioner (GP) in Australia.

The volume of transcatheter aortic valve implantation (TAVI) for treatment of isolated aortic stenosis has far surpassed surgical aortic valve replacement (SAVR). There has been a consequent increase in TAVI explantation, now the fastest growing cardiac surgical procedure. Transcatheter heart valve explantation can be technically complex, with higher perioperative morbidity and mortality than routine SAVR or valve-in-valve TAVI.

Objective: We present our experience with endovascular Bentall procedure (Endo-Bentall) using a modular valve conduit (Endo-Bentall) in high-risk patients with aortic root pathologies.
Methods: The physician constructed Endo-Bentall device is composed of a self-expanding transcatheter aortic valve (TAVR), aortic endovascular stent graft (TEVAR), and two wire-reinforced fenestrations for coronary artery stenting. The TAVR valve is sutured into an appropriately sized TEVAR graft.

Objective: Over 30% of patients presenting with acute type A aortic dissection (ATAAD) are considered high - risk or inoperable. This study aims to investigate the early and mid-term outcomes of complex endovascular aortic repair of aortic root, ascending aorta, and aortic arch among patients with ATAAD.
Methods: From January 2018 to January 2023, 29 patients who were considered high risk for open operation underwent endovascular aortic repair.
