Management of giant left atrial thrombus late after transcatheter mitral valve-in-ring replacement using a transcatheter aortic valve: a case report.

BMC Cardiovasc Disord

November 2024

Department of Internal Medicine I, Cardiology, Angiology, Intensive Medical Care, University Hospital Jena, Am Klinikum 1, 07747, Jena, Germany.

Background: In symptomatic high-risk patients with severe mitral valve regurgitation (MR), who are not eligible for surgery, Transcatheter edge-to-edge repair (TEER) or transcatheter mitral valve replacement (TMVR) may be an option, especially when surgical mitral valve repair by annuloplasty has been performed earlier. After TMVR, the appropriate anticoagulation regimen is still matter of debate.

Case Presentation: We here report on a 78-year-old frail lady with heart failure and atrial fibrillation who underwent surgical reconstruction of the mitral valve nine years ago.

Background: Anatomical factors may preclude transfemoral (TF) arterial access for transcatheter aortic valve implantation (TAVI). Transcaval (TCav) access has been utilized as an alternative access for these patients. We aimed to investigate the outcomes of TCav access in patients undergoing TAVI.

This prospective, observational study evaluated Hyperspectral Imaging (HSI) to assess the effects of cardiac surgery and cardiopulmonary bypass (CPB) on microcirculation. 40 Patients with severe aortic stenosis were enrolled. 20 patients underwent transapical/transaxillary/transaortic aortic valve replacement (TAVR), 20 underwent an open surgical approach with CPB (SAVR).

Introduction:  Lactate dehydrogenase (LDH) is a standard postoperative marker for hemolysis in the presence of paravalvular leakage (PVL) after replacement of the aortic valve (AVR). LDH is elevated in certain valves by a fluttering phenomenon. Previous studies suggested a correlation between microparticles (MPs) and LDH elevation after AVR.

Long-term outcomes of transapical-transcatheter aortic valve replacement.

Gen Thorac Cardiovasc Surg

October 2024

Department of Cardiovascular Surgery, Osaka University Graduate School of Medicine, 2-2 Yamadaoka, Suita, 565-0871, Osaka, Japan.

Objective: Transapical-transcatheter aortic valve replacement is one of the main interventions indicated for patients where access via peripheral vessels is challenging. However, there have been no reports on the long-term outcomes of this intervention. Here, we report the long-term outcomes of this intervention.
