Aims: We aimed to evaluate transcatheter mitral valve implantation (TMVI) using predominantly balloon-expandable transcatheter heart valves (THV) in patients with a landing zone for a percutaneously delivered prosthesis.
Background: Patients with a degenerated mitral valve bioprosthesis, annuloplasty ring, and mitral annulus calcification (MAC) considered at high surgical risk currently represent a treatment challenge. TMVI is an alternative treatment option.
Methods: Retrospective analysis of patients with symptomatic degenerated mitral valve bioprosthesis, or annuloplasty ring, and MAC treated with TMVI between November 2011 and April 2021. Endpoints were defined according to Mitral Valve Academic Research Consortium (MVARC) criteria and included device and procedure success at 30 days as well as mortality at 30 days and 1 year after the procedure.
Results: A total of 77 patients underwent TMVI (valve in valve [ViV = 56], valve in ring [ViR = 11], and valve in MAC [ViMAC = 10]). There was a trend toward higher technical success (all = 93.5%, ViV = 96.4%, ViR = 90.9%, ViMAC = 80%, p = 0.06) and lower 30-day (all = 11.7%, ViV = 10.7%, ViR = 9.1%, ViMAC = 20%, p = 0.49) and 1-year mortality (all = 26%, ViV = 23.2%, ViR = 27.3%, ViMAC= 40%, p = 0.36) after ViV and ViR compared to ViMAC.
Conclusion: TMVI represents a reasonable treatment option in selected patients with MAC or who are poor candidates for redo mitral valve surgery. Technical success and survival up to 1 year were not significantly dependent on the subgroup in which TMVI was performed.

Patients with atrial fibrillation, venous thrombosis, and mechanical heart valve (MHV) regularly undergo procedures on a daily basis, for which they require bridging anticoagulation, but this poses significant challenges. Bridging anticoagulation involves temporary interruption of long-term anticoagulation therapy for procedures and continued overlap with short-acting anticoagulants during perioperative period. Heparin-based agents are often used for overlapping in perioperative period to reduce the risk of thromboembolism, but the evidence for benefit particularly in patients with MHV remains limited.

Background: Chronic kidney disease (CKD) is associated with a higher prevalence of valvular diseases and increased mortality from cardiovascular causes. Factors that influence the genesis of cardiac valve calcification (CVC) in these patients are not well-defined.
Objective: To determine the risk factors for valvular calcification in patients with CKD.

Atrial functional mitral regurgitation (AFMR) is an increasingly recognized subtype of mitral regurgitation, characterized by left atrial remodelling and mitral annular dilation in the absence of primary mitral valve disease or left ventricular dysfunction. Closely linked to chronic atrial fibrillation and heart failure with preserved ejection fraction, AFMR is associated with poor clinical outcomes and represents a growing therapeutic challenge. This expert opinion paper summarizes current evidence on the epidemiology, pathophysiology, diagnosis and management strategies, including medical therapy and emerging data supporting surgical and transcatheter interventions in selected patients.

A middle-aged female presenting with progressive heart failure was admitted to the emergency department. She had a history of mitral and aortic valve replacement and a reoperation involving the Konno procedure. Echocardiography suggested a possible paraprosthetic leakage, which was confirmed during surgery.

Objective This research investigated the application of real-time, three-dimensional speckle tracking imaging (RT-3D-STI) to evaluate left atrial (LA) function in individuals suffering from hypertensive heart disease (HHD) and heart failure with preserved ejection fraction (HFpEF).Material and methods This retrospective study included 100 patients with HHD and HFpEF hospitalized from August 2023to June 2024 (HFpEF group). 100 healthy individuals undergoing physical examinations comprised the control group.
