Article Synopsis
  • This study investigated the use of 3D intraoperative transesophageal echocardiography (3D-IOTEE) to understand the causes of residual mitral regurgitation (MR) after mitral valve repair and how it affects the need for mitral valve replacement (MVR).
  • Out of 767 patients who underwent valve repair, 92 patients needed a second cardiopulmonary bypass due to residual MR, which were categorized based on the underlying causes.
  • Results showed that different mechanisms of residual MR significantly influenced the rates of conversion to MVR, with inter-scallop malcoaptation being the most likely to lead to replacement surgery (68.8%), while others like suture dehiscence had

Article Synopsis
  • * A meta-analysis was conducted using 25 studies, revealing in-hospital and 30-day mortality rates of 11.8% and 14.1%, respectively, with higher mortality linked to residual severe mitral regurgitation.
  • * Despite observed procedural complications, the findings suggest that M-TEER may still offer favorable short-term outcomes for these high-risk patients.

Right ventricular (RV) dysfunction is an indication for tricuspid valve (TV) surgery in patients with severe isolated tricuspid regurgitation (TR). Postoperative RV dysfunction is associated with poor outcome; however, the longitudinal changes in RV function before and after surgery have not been established. We retrospectively analyzed 24 patients who underwent TV surgery for isolated severe TR.

Patients with rare conditions such as cardiac amyloidosis (CA) are difficult to identify, given the similarity of disease manifestations to more prevalent disorders. The deployment of approved therapies for CA has been limited by delayed diagnosis of this disease. Artificial intelligence (AI) could enable detection of rare diseases.

Background: Long-term predictors of recurrent mitral regurgitation (MR) after mitral valve plasty (MVP) remain to be elucidated. This study sought to determine the prognostic factors of recurrent MR during long-term follow-up after MVP, by analysing findings of three-dimensional transoesophageal echocardiography (TEE) conducted after MVP.

Methods: This study analysed 207 patients who underwent MVP for A2 and/or P2 prolapse and received TEE before discharge.
