Background: Mitral annular calcification (MAC) is characterized by severe calcification of mitral annulus and might be associated with both mitral regurgitation and stenosis. It is technically challenging for both surgical and percutaneous approach and is burdened by high mortality.
Case Summary: The present case report describes a complex case of mitral steno-insufficiency (baseline transvalvular gradient = 5 mmHg, effective regurgitant orifice area 0.45 cm, vena contracta 0.8 cm), due to MAC in an 83-year-old lady. In consideration of the clinical context (MAC) and patient's several comorbidities and history of previous surgical interventions, she was deemed not suitable for surgery and a percutaneous treatment was selected (valve-in-MAC). Due to significant paravalvular leak, further implantation of a plug was required.
Conclusion: The MAC represents a clinical and technical challenge for surgery. Transcatheter mitral valve implantation in MAC is a feasible alternative although it is technically challenging and burdened by high mortality. Detailed procedural planning is of utmost importance to achieve successful outcomes.

Background: Transcatheter edge-to-edge mitral valve repair (M-TEER) using the MitraClip system is primarily performed using the transfemoral approach. However, when this approach is not feasible, the transjugular approach can be used as an alternative.

Background: The PASCAL P10 system for mitral valve transcatheter edge-to-edge repair has undergone iterations, including introduction of the narrower Ace implant and the Precision delivery system.
Objectives: The study sought to evaluate outcomes and the impact of PASCAL mitral valve transcatheter edge-to-edge repair device iterations.
Methods: The REPAIR (REgistry of PAscal for mltral Regurgitation) study is an investigator-initiated, multicenter registry including consecutive patients with mitral regurgitation (MR) treated from 2019 to 2024.
