Background: The Magenta Elevate is a 9-F, self-expanding, catheter-mounted pump delivered sheathed through a commercially available 10-F femoral introducer over the wire to the left ventricle (LV), providing temporary hemodynamic support up to an equivalent of normal cardiac output.
Objectives: The authors sought to assess the feasibility and outcomes of Elevate-supported high-risk percutaneous coronary intervention (HR-PCI) in a first-in-human study and study the hemodynamic impact of high-output support during prolonged interventional left main coronary artery (LM) occlusions.
Methods: In this study, 14 patients underwent Elevate-supported HR-PCI, with 8 patients undergoing 20 prolonged (39 ± 16 seconds) balloon occlusions of an unprotected LM.
This study evaluates the efficacy of annuloplasty repair as a standalone procedure for treating bileaflet mitral valve prolapse with mitral regurgitation (MR). Various flexible ring bands for MR of different severities were compared to assess their biomechanical impact and treatment outcomes. Computational beating heart models, based on the Living Heart Human Model, were utilized to simulate annuloplasty repairs.

The aims of this study were to test whether convolutional neural networks could be trained to estimate age and predict sex using standard transthoracic echocardiography and to evaluate the prognostic implications.
Methods: The algorithm was trained on 76,342 patients, validated in 22,825 patients, and tested in 20,960 patients.
Article Synopsis
- Implantable devices help patients with heart failure by working alongside medicines to treat the condition and improve their health.
- While some devices are supported by strong evidence and show positive effects, others need more research before they can be widely used.
- The Heart Failure Association and European Heart Rhythm Association suggest a better way to use these devices in care programs to help patients more effectively.
Article Synopsis
- The study examines the long-term outcomes of a ring-only repair (ROR) technique for treating severe mitral regurgitation (MR) caused by degenerative bileaflet valve issues, particularly Barlow's disease.
- Eighty patients were treated, with a notable follow-up period showing a very low recurrence rate of MR (1%) and high survival rates, indicating the effectiveness of ROR in this context.
- The findings suggest ROR is a safe and straightforward method for these patients, with minimal complications and a 10-year freedom from recurrent MR at 97%.
