Article Abstract
Objectives: The aim of this report is to describe transcatheter edge-to-edge mitral valve repair using the PASCAL device in patients with medial commissure (MC) flail-induced primary mitral regurgitation.
Key Steps: Perform a transseptal puncture above the MC. Insert the guide sheath (GS) into the left atrium (LA), guide the steerable catheter (SC) into the GS, and direct it toward the mitral valve. Withdraw the GS to the right atrium while maintaining the SC in the LA to approach the MC. Adjust the anterior-posterior trajectory using the GS flex knob. After leaflet grasping and PASCAL deployment, readvance the GS over the SC into the LA.
Potential Pitfalls: Without a GS backup, the SC may become parallel to the aorta, hindering anterior leaflet visualization and complicating grasping.
Take-home Messages: The PASCAL device can be deployed safely even if the GS is withdrawn to the right atrium. Performing a transseptal puncture directly above the MC is essential to guide the SC when retracted.

Robotic mitral annuloplasty using a semi-continuous three-suture technique with a flexible band.
Multimed Man Cardiothorac Surg
September 2025
Robotic mitral repair is often associated with longer ischaemic and cardiopulmonary bypass times, particularly early in the learning curve. We demonstrate a semi-continuous, three-suture technique for robotic annuloplasty that retains the mechanical principles of traditional interrupted sutures while leveraging the advantages of robotic precision and exposure. The use of pre-knotted sutures minimizes intra-cardiac knot tying, further enhancing procedural efficiency.

A left ventricular sub-mitral thrombus without an aneurysm is a previously unreported rare occurrence. We aim to bring attention to this finding in a case of colorectal adenocarcinoma.An early 60s-year-old female presented with bleeding per rectum, weight loss and fatigue and was found to have colorectal carcinoma with metastasis based on examination, imaging and biopsy findings.

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.

Background: Routine preoperative echocardiograms (ECHOs) are frequently obtained in patients undergoing minimally invasive repair of pectus excavatum (MIRPE), but the benefit and necessity of preoperative screening remain debated. In this study, we sought to quantify the proportion of preoperative ECHOs that had clinically significant findings.
Methods: We conducted a retrospective review of 255 patients who underwent MIRPE at a single pediatric referral center from 2018 to 2023.
Oral anticoagulation in patients with atrial fibrillation and heart valve prosthesis: a substudy from the LAAOS III Trial.

Objective: Societal guidelines recommend vitamin K antagonists (VKAs) for atrial fibrillation patients with recent biological valve implantation, but the safety and efficacy of direct oral anticoagulants (DOACs) in this setting remain uncertain, especially in the early postoperative period. This substudy of the Left Atrial Appendage Occlusion Study (LAAOS) III trial aimed to compare thromboembolic and bleeding outcomes in patients discharged on VKAs versus DOACs after bioprosthesis implantation or mitral valve repair.
Methods: A total of 2,645 patients were included, with 461 discharged on DOACs and 2184 on VKAs.
