is a gram-negative bacterium assigned to the family of . Less than 1% of Q-fever infection leads to infective endocarditis (IE). Cases of reported pulmonary valve (PV) prosthesis endocarditis are scarce. A patient with a PV prosthesis endocarditis caused by was seeking asylum in Germany. Prosthesis replacement was performed. All obtained blood cultures showed no growth as well as microbiological cultures of the prosthetic valve tissue. A polymerase chain reaction analysis on the explanted prosthesis detected DNA of spp. Diagnosing IE caused by requires an interdisciplinary effort from both clinicians and microbiologists.

Infective endocarditis (IE) is an infection that affects the heart valves, endocardium, and great vessels. It has a mortality rate of approximately 30% per year, so early diagnosis is essential to reduce morbidity and mortality. Cardiac angio-CT triggered by electrocardiogram (ECG) has been considered in IE management guidelines in recent years, given its high spatial resolution, contributing to the diagnosis and evaluation of valvular complications (vegetations, perforations, dysfunctions), perivalvular (abscesses, pseudoaneurysms, prosthesis dehiscence, fistulas) and compromised coronary arteries (embolism), allowing early diagnosis and treatment.

Objectives: Transcatheter edge-to-edge repair (TEER) is an alternative for patients with severe degenerative mitral regurgitation (MR). The objective of this study was to compare the outcomes of surgery and TEER in older patients with degenerative MR patients using real life data.
Methods: Consecutives older patients (≥ 65 years-old), with severe symptomatic, degenerative MR requiring surgery or TEER between 2013 and 2023 were included.

Background: Reports on the durability of transcatheter aortic valve replacement (TAVR) prostheses are scarce and confounded by varying definitions and competing risks of death.
Objectives: The authors sought to determine the incidence, predictors, and clinical outcomes of hemodynamic valve deterioration (HVD) according to the Valve Academic Research Consortium 3 definition after TAVR.
Methods: We analyzed consecutive patients undergoing TAVR in the prospective Bern TAVI (Transcatheter Aortic Valve Implantation) registry between August 2007 and June 2022 for the incidence and predictors of HVD and performed case control-matching to compare outcomes according to HVD.

Background: Lifetime treatment of aortic valve disease is a matter of increasing debate. Although the risks of a second aortic valve intervention are recognized, little attention has been given to the challenges of a third.
Objectives: This study delves into the clinical characteristics, indications, and outcomes of patients undergoing 3 aortic valve interventions.

Case Report: We report the case of a 63-year-old patient who underwent aortic valve replacement with a biological valve for a bicuspid aortic stenosis, and LIMA-IVA single-bypass surgery. Two weeks later, he presented with Enterococcus faecillis bacteremia, attributed to left pyelonephritis and successfully treated with Amoxicillin. Two months after his surgery, he had a new bacteremia due to Enterococcus faecalis and we discovered a pseudo-aneurysm of the mitro-aortic trigone.
