Standard operative mitral valve replacement for mitral stenosis in the setting of severe mitral annular calcium has been associated with increased morbidity and mortality. Inability to ensure a well seated prosthesis may lead to periprosthetic leak. We present a case of severe paravalvular leak, causing significant hemolysis, after mitral valve replacement with underling severe mitral annular calcium. The leak was successfully repaired using a transseptal percutaneous approach, with subsequent resolution of hemolysis.

Secondary mitral regurgitation (SMR) is common in patients with heart failure (HF). Although randomized clinical trials have been focused on the treatment of severe SMR, the prognostic role and potential for treatment of moderate SMR cannot be overlooked. The randomized RESHAPE-HF2 trial included patients with moderate and severe SMR with consistent findings in both groups, raising the hypothesis that transcatheter correction of moderate SMR could have beneficial effects, although this needs further investigation.

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.

Cardiac resynchronization therapy (CRT) improves outcomes in heart failure, but prior interventions like percutaneous mitral annuloplasty may hinder lead placement. We present a 70-year-old male with ischemic cardiomyopathy and severe functional mitral regurgitation who previously received a Carillon device. Due to coronary sinus inaccessibility, left bundle branch area pacing optimized cardiac resynchronization therapy (LOT-CRT) was performed.

Background: Long-term outcomes of transcatheter mitral valve edge-to-edge repair (TEER) are compared with medical therapy remain under investigation. This study evaluated the 3-year effects of MitraClip on mitral regurgitation (MR) severity, ventricular remodeling, and clinical outcomes in high surgical-risk patients.
Methods: A single-center retrospective cohort included 31 MitraClip patients (2016-2023) and 30 contemporaneous controls on maximally tolerated guideline-directed medical therapy.

Background: Pulmonary hypertension (PH) often coexists in patients undergoing transcatheter edge-to-edge mitral valve repair procedure (M-TEER). Its pre-procedural severity is considered a negative prognostic marker. Whether the post-procedural PH resulting from M-TEER can also serve as a long-term prognostic marker is unknown.
