Surgical implantation of a complete or incomplete ring to reduce the valve annulus and improve leaflet coaptation is the mainstay of mitral valve surgery. The Cardioband® system (Edwards Lifesciences) was designed to address the pathophysiological mechanism of annular dilatation through a catheter-based approach. We present the histopathological workup of a Cardioband® device, which had been implanted 21 months earlier in a 34-year-old male with ischemic cardiomyopathy. Device examination demonstrate a well-positioned and securely anchored device. The described tissue reactions may have an impact on choice of device and timing in case of re-do surgery.

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.

Purpose To investigate the determinants and effect of right ventricular (RV) dysfunction in aortic regurgitation (AR) using cardiac MRI. Materials and Methods This study included patients with moderate or severe AR who were enrolled in the DEBAKEY-CMR registry between January 2009 and June 2020. Patients with previous valve intervention, cardiomyopathy deemed unrelated to AR, severe aortic stenosis, and other confounders were excluded.

Objectives: Surgical options for mitral valve repair in dogs are unstandardized and influenced by various factors. This study describes a four-point surgical technique (MI-4) to reduce mitral regurgitation and provides data from a study of dogs with 12 months of follow up.
Methods: Twenty-five dogs with stages C or D mitral insufficiency were treated by one of two surgeons using the MI-4 procedure at Ueno no Mori Animal Hospital between October 2021 and May 2023.

Background: Mitral annular disjunction (MAD) is a controversial entity. Recently, a distinction between pseudo-MAD, present in systole and secondary to juxtaposition of the billowing posterior leaflet on the left atrial wall, and true-MAD, where the insertion of the posterior leaflet is displaced on the atrial wall both in diastole or in systole, has been proposed. We investigated the prevalence of pseudo-MAD and true-MAD.
