The article is devoted to long-term results of pilot clinical investigation of using mononuclear fraction of autologous bone marrow cells as an additional procedure to standard surgical treatment of heart valve failure in order to improve local perfusion and contractive ability of the myocardium. The article presents results of an analysis of findings of the examination of 7 living patients within 6 years or 7 years after operation as also data of pathologicoanatomical investigation of three dead patients. The data obtained show the safety and effectiveness of this method of cell therapy in patients with heart valve failure.

Comparison of Outcomes Between Low-Risk Aortic Valve Replacement Trials and a Surgical Registry.
JAMA Netw Open
January 2025
Division of Cardiothoracic and Vascular Surgery, Columbia University Irving Medical Center, New York, New York.
Importance: It remains unknown whether outcomes of the Placement of Aortic Transcatheter Valves 3 (PARTNER 3) and Evolut Low Risk trials are comparable with surgical outcomes in nontrial settings, considering the added risk of concomitant cardiac operations.
Objective: To compare 30-day mortality and stroke incidences of patients in the surgical aortic valve replacement (SAVR) arm of low-risk trials with those of similar patients in the US Society of Thoracic Surgeons Adult Cardiac Surgery Database (STS ACSD).
Design, Setting, And Participants: A cross-sectional sampling study was conducted of adults in the STS ACSD with severe aortic stenosis at low surgical risk for AVR who underwent SAVR during the years low-risk AVR trials (PARTNER 3 and Evolut Low Risk) were enrolling (calendar years 2016-2018).

Background: Conduction disturbances are a frequent occurrence after tricuspid valve surgeries, and their management is challenging.
Case Presentation: We present a case of 16-year-old male patient who presented with episodes of presyncope. At the age of 7 years, he underwent tricuspid valve replacement surgery with a biological prosthesis for infective endocarditis sourced from a gluteal abscess.
[Bivalvular Infective Endocarditis with Involvement of the Mitroaortic Fibrosis by Staphylococcus lugdunensis].

Bivalvular infective endocarditis is a clinical presentation that is associated to a greater extent with adverse outcomes. The involvement of the intervalvular mitral-aortic fibrosa is a rare complication associated with high mortality rates, requiring high complexity surgery. We report a case of a young male presenting to the emergency department with bivalvular endocarditis and mitral-aortic intervalvular fibrosa involvement.

Background: For clinicians treating patients with infective endocarditis (IE), identifying the causative microorganisms poses a critical diagnostic challenge. Standard techniques including blood and heart valve cultures often yield inconclusive results. According to the recent 2023 Duke-ISCVID Criteria, molecular methods represent potent tools to enhance this aspect of IE diagnostics and guide subsequent therapeutic strategies.

Acta Cardiol
January 2025
Cardiology, AZ Groeninge, Kortrijk, Belgium.
Objectives: Edge-to-edge mitral valve repair with MitraClip leads to a differed flow pattern and a decreased flow velocity at the left ventricle apex. This combination may lead to initiation of thrombus formation, especially in patients with severely reduced ejection fraction. The prevalence and mechanism of left ventricular thrombus formation after MitraClip implantation is still unknown.
