Background: , an opportunistic pathogen that can cause infections in multiple parts of the human body, has multiple drug resistance and a high mortality rate. However, there have been few reports of infective endocarditis (IE) caused by , which means that diagnosis and treatment face challenges that cannot be ignored. Rapid and accurate identification and drug sensitivity results are needed to make timely treatment adjustments.
Case Presentation: An 81-year-old man presented with recurrent fever and increased infection index for more than a month. Based on his clinical symptoms, infection index, reduplicative blood cultures, and results of transesophageal echocardiography, he was ultimately diagnosed with infective endocarditis caused by . The patient had a favorable outcome with a 6-week course of intravenous antibiotic therapy.
Conclusion: This is a rare and successfully cured case of IE caused by the pathogen of , which is difficult not only in diagnosis but also in treatment. This case provides a certain referential significance to the treatment of caused IE in clinical practice.

Objective: To compare the clinical outcomes of double-valve replacement (DVR) using bovine pericardial and porcine bioprostheses, using a nationwide administrative claims database.
Methods: Adult patients (age ≥40 years) who underwent bioprosthetic DVR between 2003 and 2018 were identified from the Korean National Health Insurance Service database. The outcomes of interest were all-cause mortality, cardiac mortality, and valve-related events, including the incidences of reoperation, endocarditis, systemic thromboembolism, and major bleeding.

Objective: To compare early and long-term clinical outcomes of bioprosthetic versus mechanical (On-X) mitral valve replacement (MVR) in patients aged 65 years and older.
Methods: This single-center retrospective study included consecutive patients equal to or older than 65 years underwent isolated MVR from 2005 to 2023. A propensity score-matched analysis was performed to compare early- and long-term clinical outcomes between patients with bioprostheses and mechanical On-X valve.

Objective: To evaluate the early postoperative morbidity, mortality, and prosthetic conduit function of patients who underwent aortic root replacement using a prefabricated bioprosthetic aortic valved conduit.
Methods: Single-center retrospective review of 124 consecutive adult patients who underwent aortic root replacement with a certified prefabricated bioprosthetic aortic valved conduit from 2021 to December 2023.
Results: Indications for operation were aortic aneurysms (n = 92), endocarditis (n = 12), deterioration of prior valve prosthesis (n = 13), and aortic dissection (n = 6).

Although generally considered harmless commensals or beneficial probiotics, species can act as opportunistic pathogens under certain clinical conditions. We describe a case of high-grade bacteremia in a 59-year-old man with a history of aortic root dilation status post Bentall procedure and bioprosthetic aortic valve replacement. The suspected source was recent dental instrumentation.

Infective endocarditis is a potentially fatal condition that can present with non-specific symptoms and rare hematologic manifestations, posing significant diagnostic challenges. We report a compelling case of a 67-year-old male with a history of type 2 diabetes, hypertension, and hyperlipidemia who sought medical attention for a five-month history of progressive iron deficiency anemia, accompanied by weight loss, fatigue, and vague constitutional symptoms. Initial extensive workup, including computed tomography of the thorax, abdomen, and pelvis, gastroscopy, colonoscopy, and transthoracic echocardiography, failed to identify an underlying cause.
