Aortic Biological Prosthetic Valve Dysfunction Secondary to Endocarditis: Is Percutaneous Valve-in-Valve an Option?

We present the case of a 69-year-old man with an aortic biological prosthetic valve. In May 2019, the patient experienced increasing dyspnea and fatigue: A diagnosis of prosthetic aortic valve dysfunction was made, leading to severe valvular insufficiency. The dysfunction of the prosthetic valve seemed to be linked to a previous infective endocarditis: after ruling out active endocarditis, the patient was treated with an off-label valve-in-valve transcatheter aortic valve implantation.

Early discharge after transfemoral transcatheter aortic valve implantation.

Background: The aim of this study was to assess the feasibility and the safety of early discharge (within 72 h) after transfemoral transcatheter aortic valve implantation (TAVI) and to identify baseline features and/or peri-procedural variables, which may affect post-TAVI length-of-stay (LoS) duration.

Methods And Results: Patients discharged within 72 h of TAVI (early discharge group) were compared with consecutive patients discharged after 3 days (late discharge group). Propensity-matched cohorts of patients with a 2:1 ratio were created to better control confounding bias.

Long-Term Results after Percutaneous Closure of Atrial Septal Defect: Cardiac Remodeling and Quality of Life.

Background: Atrial septal defect (ASD) represents a common congenital heart malformation, cause of right ventricle (RV) volume overload, pulmonary hypertension, atrial arrhythmias, and paradoxical emboli. Percutaneous closure represents the treatment of choice for ASD. However, it is still difficult to associate symptoms to the success of ASD treatment.
