was recently defined as a species and has previously often been mistaken for due to the difficulties of conventional laboratory methods to distinguish the two species. The clinical presentation of infections caused by is largely unknown, and its virulence has since the definition of the species been debated. Here we present, to our knowledge, the first case of infective endocarditis due to with valve vegetations visualized on echocardiography. The 74-year-old male patient with biological aortic valve prothesis presented with a rapid onset of diffuse symptoms and his condition hastily deteriorated to septic shock followed by several complications such as intracranial septic emboli, severe heart failure, and intracardiac thrombus. After conservative treatment and management of the multiple complications, the patient recovered and was eventually discharged to his original housing situation.

Introduction: Acute kidney injury (AKI) is notably prevalent after cardiac surgery for patients with active infective endocarditis. This study aims to create a machine learning model to predict AKI in this high-risk group, improving upon existing models by focusing specifically on endocarditis-related surgeries.
Methods: We analyzed medical records from 527 patients who underwent cardiac surgery for active infective endocarditis from January 2012 to December 2023.

Background: With the rapid expansion of transcatheter aortic valve replacement (TAVR), TAVR valve explantation is also increasing. Nevertheless, previous reports on Lotus Edge valve explantation are limited to only two reports, none of which include intraoperative videos. Therefore, we report the case of an older adult who underwent a 2-year-old Lotus Edge valve explantation, after developing prosthetic valve endocarditis (PVE) and aortic annular abscess, with a strong indication for a TAVR explantation and surgical aortic valve replacement (AVR).

Importance: Infective endocarditis (IE) caused by Staphylococcus aureus is associated with high mortality, approximately 20% to 30%, mostly in the first month, with no improvement in recent decades. Current opinion is that antistaphylococcal penicillin and cefazolin are equally effective in treating methicillin-susceptible S aureus (MSSA) IE, and both are recommended as possible first-line treatments. Most MSSA strains carry the β-lactamase blaZ gene, and some blaZ-positive strains exhibit an inoculum effect, meaning increased minimum inhibitory concentrations at high inoculum.

Infective endocarditis (IE) primarily affects the endocardium of the heart valves. One of the common neurological complications of IE is the embolization of endocardial vegetation, which can obstruct the cerebral arteries. We describe the case of a 47-year-old male patient who developed neurological symptoms as a complication of IE.

Background: Although transcatheter aortic valve implantation (TAVI) is performed for very elderly patients in whom surgical aortic valve replacement (SAVR) poses unacceptably high operative risk, some of these patients are ultimately forced to undergo open surgery when TAVI is complicated by infective endocarditis (IE). To our knowledge, there have been no reports of cases with periannular extension of IE and atrioventricular block successfully treated by antibiotics without valve replacement.
Case Summary: An 80-year-old Japanese man who had undergone TAVI developed IE with loss of consciousness on Day 39 after the procedure.
