Ischemic mitral regurgitation is the regurgitation seen with structurally normal valve leaflets that occurs in approximately 20% of patients after myocardial infarction and 56% of patients with congestive heart failure caused by ischemic or nonischemic cardiomyopathy. The initiating event is an ischemic insult that results in remodeling of the left ventricle toward a more spherical shape and new wall motion abnormalities. These changes lead to annular dilation and subvalvular distortion that prevent the mitral leaflets from coapting and closing completely during the contraction phase. Treatment options include coronary revascularization, ring annuloplasty, valve repair and replacement, or left ventricle reconstruction by way of localized reshaping or resection. Pharmacotherapy, aimed at raising left ventricular pressure without increasing tethering or left ventricular volume, is included in the treatment options for improving ischemic mitral regurgitation.

Objectives: The ValveClamp system (Hanyu Medical Technology) is a novel transcatheter edge-to-edge repair (TEER) system designed for ease of operation; however, there is a lack of data on its application in secondary mitral regurgitation (SMR). The authors report the mid-term outcomes of TEER using the ValveClamp system in SMR.
Methods: The study prospectively analyzed consecutive severe SMR patients who underwent transapical ValveClamp implantation at 10 Chinese centers.

Aims: Ischaemic mitral regurgitation (MR) is a dynamic condition influenced by global and regional left ventricular remodelling as well as mitral valvular deformation. Exercise testing plays a substantial role in assessing the haemodynamic relevance of MR and is recommended by current guidelines. We aimed to assess the prevalence, haemodynamic consequences, and prognostic impact of dynamic MR using isometric handgrip exercise.

Objective: Infective endocarditis (IE) is associated with significant morbidity and mortality and places patients at risk for subsequent peripheral vascular emboli. Our goals were to analyze the incidence of peripheral emboli and their associated complications and outcomes.
Methods: A retrospective single-center review of all patients with IE from 2013-2021 was performed.
