Bicuspid aortic valve (BAV) disease is a spectrum of anomalies ranging from mild underdevelopment of a commissure to severe underdevelopment of two interleaflets triangles. Many different classifications of BAV, based on the echocardiographic, surgical or pathological appearance of the valve, and more recently on cardiac CT, have been proposed. We describe a simple technique, based on three-dimensional curved multiplanar reconstruction images, to obtain a pathology-like visualization of the full line of insertion (Hinge) of the aortic valve leaflets and of the interleaflet triangles with cardiac CT. This method could help to obtain a detailed categorization of any specific BAV anatomy based on the degree of underdevelopment (or on the absence) of one interleaflet triangle. Adherence to this concept could help to improve the imaging based analysis of BAV patients undergoing TAVR, and could lead to the adoption of a BAV classification based on the effective pathologic appearance of the valve also for patients undergoing TAVR.

Epicardial fat tissue, a hidden enemy against the early recovery of left ventricular systolic function after transcatheter aortic valve implantation.
Int J Cardiol Heart Vasc

Background: Epicardial fat tissue (EFT) is an active organ that can affect cardiac function and structure through endocrine, paracrine, and proinflammatory mechanisms. We hypothesized that greater thickness of EFT may harm the recovery of left ventricular (LV) systolic function in patients with severe aortic stenosis (AS) and reduced LV ejection fraction (EF ≤ 50 %) undergoing transcatheter aortic valve implantation (TAVI).
Methods: A sixty six patients with severe AS and 20 % ≥ LVEF ≤ 50 % who underwent TAVI were included.

Background: Prognosis assessments for transcatheter aortic valve implantation (TAVI) patients remain challenging, particularly as the indications for TAVI expand to lower-risk patients. This study assessed the prognostic value of the tricuspid regurgitation impact on outcomes (TRIO) score in patients after TAVI.
Methods: This single-center study included 530 consecutive patients who underwent TAVI.

With the aging of the general population and the rise in surgical and transcatheter aortic valve replacement, there will be an increase in the prevalence of prosthetic aortic valves. Patients with prosthetic aortic valves can develop a wide range of unique pathologies compared to the general population. Accurate diagnosis is necessary in this population to generate a comprehensive treatment plan.

Transcatheter aortic valve implantation (TAVI) involves complex decisions regarding perioperative anticoagulation, with continuation or interruption of oral anticoagulation presenting distinct risks and benefits. This systematic review and meta-analysis compared the clinical outcomes of these two strategies during TAVI. We conducted a comprehensive literature search across multiple electronic databases, including PubMed, Embase, Cochrane Library, and Web of Science, from inception to November 2024.
