Article Abstract
Background: Minimally invasive mitral valve surgery (MIMVS) is superior to "classical" mitral valve surgery via a sternotomy regarding wound healing and postoperative pain. It is however a more challenging procedure. Patients' preference is leading clearly toward minimally invasive approaches, and surgeons are driven by upcoming new technologies in interventional procedures such as the MitraClip. Especially in re-do cases, the access via right mini-thoracotomy, as previously non-operated situs, is a possible advantage over a re-sternotomy. We therefore retrospectively analyzed our result regarding MIMVS in re-do cases at our institute.
Methods: From January 2011 and June 2016, 33 operations were MIMVS re-do procedures. Mean age was 60 years (±16 years), and 51% were male.
Results: Sixty-one percent were elective cases, 29% were urgent cases, and 9% were emergency operations. Operation times, cardiopulmonary bypass (CPB) times, and clamp times were 235 minutes (±51 min), 149 minutes (±42 min), and 62 minutes (±45min), respectively. Mitral valve repair and replacement was performed in 24% ( = 8) and 76% ( = 25), respectively. Overall in-hospital mortality, apoplexy, and re-operation rates (all for bleeding) were 0% ( = 0), 3% ( = 1), and 9% ( = 3). New onset of dialysis was required in two (6%) patients. Two (6%) patients developed superficial wound infection. Overall intensive care unit (ICU) and hospital stay was 3 days (±4 days) and 15 days (±7 days), respectively.
Conclusion: MIMVS for re-do cases can be performed with minimal mortality and morbidity and therefore represents a safe alternative to conventional mitral valve surgery in cardiac re-do operations. However, postoperative morbidity is highly dependent on preoperative patient status.

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.

Population Health Research Institute, Hamilton Health Sciences, McMaster University, Ontario, Canada.
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.
