Aims: The aim of our study is to report our single-centre experience with concomitant MitraClip (MC) and left atrial appendage occlusion (LAAO) and further to assess the feasibility, safety and short-term outcome of such an approach.
Methods And Results: Twenty-five consecutive patients underwent MC with concomitant LAAO at our hospital (combined group). As a control group, 25 consecutive patients with atrial fibrillation (AF) undergoing standalone MC were selected. Baseline parameters were equal between the two groups. Patients in the combined group had longer procedural time (90.0 min vs. 66.0 min, p=0.02) and radiation time (32.0 min vs. 18.0 min, p=0.01). There were no procedural deaths. At 30 days, one patient died due to cerebral haemorrhage (combined vs.
Control: 4% vs. 0%, p=0.32) and two had acute kidney injury (combined vs.
Control: 4% vs. 4%, p=1.00). In multivariate analysis, the association of LAAO with device or procedural success was not significant.
Conclusions: LAAO along with MC in a single stage procedure is feasible. These preliminary results have to be validated in a large randomised study, in order to assess the efficacy of combined LAAO that can be expected to become evident only after longer follow-up.

Feasibility of combined therapy: percutaneous left atrial appendage closure and transcatheter edge-to-edge repair.
Cardiovasc Interv Ther

Patients with atrial fibrillation (AF) often present with concomitant significant mitral regurgitation (MR). Percutaneous left atrial appendage closure (LAAC) is indicated for patients with AF to prevent thromboembolism and reduce the need for long-term anticoagulation. Transcatheter edge-to-edge repair (TEER) is recommended for patients with significant MR.

Article Synopsis
- * An 89-year-old man experienced severe MR after surgery, requiring careful monitoring and the use of transcatheter edge-to-edge repair (TEER) to treat his condition without interfering with the dislodged annuloplasty ring.
- * The discussion highlights that using the G4-MitraClip® system for TEER is both safe and feasible for patients like this, and emphasizes the importance of pre-operative imaging techniques to ensure successful treatment.
Combined Use of MITRACLIP and Ventricular ASSIST Devices in Cardiogenic Shock: MITRA-ASSIST Registry.
J Clin Med

Cardiology Department, La Paz University Hospital, 28046 Madrid, Spain.
Article Synopsis
- Patients with cardiogenic shock (CS) and mitral regurgitation (MR) face high surgical risks, but the study investigates the effectiveness of transcatheter edge-to-edge therapy (TEER) combined with mechanical circulatory support (MCS) for these patients.
- The MITRA-ASSIST study looked at 24 patients with CS and MR treated with TEER and MCS across nine Spanish centers, revealing a procedural success rate of 95.8% and 87.5% in-hospital survival.
- At 12 months, 25% of patients died, and 33.3% experienced either death or hospitalization for heart failure, suggesting that TEER combined with MCS could be a viable treatment
Outcomes of COMBO therapy for severe mitral regurgitation compared with transcatheter edge-to-edge repair.

Background: There are different types of transcatheter mitral valve repair (TMVr) currently in clinical use, including leaflet approximation, annular cinching, and restoration of the chordal apparatus of the mitral valve (MV). While the concomitant combination (COMBO) therapy of mitral transcatheter edge-to-edge repair (M-TEER) with another TMVr concept has been proven feasible, potentially offering patient-tailored treatment for severe mitral regurgitation (MR), a comparison with M-TEER alone has not been made.
Aims: To evaluate the procedural and clinical outcome of COMBO therapies compared with M-TEER alone.

Background: mitral regurgitation (mr) is the most common valvular heart disease (vhd) in the elderly and tends to be more prevalent in women. while relevant sex differences in outcomes are evident in surgically treated collectives, there are very limited and conflicting sex-specific data for the growing cohort of patients undergoing transcatheter edge-to-edge repair (teer).
Objective: to investigate whether sex impacts procedural safety and efficacy, and in-hospital- and long-term outcomes, after teer for mr.
