Summary: This study assessed risk factors for the recurrence of mitral regurgitation (MR) or functional mitral stenosis in patients undergoing mitral valve repair for isolated posterior mitral leaflet prolapse. The study found that leaflet resection with a large partial band may be the optimal strategy for treating isolated posterior mitral valve prolapse.

Summary: The study found no differences in long-term survival or reoperation rates between anterior and posterior repairs for degenerative mitral valve disease. Surgeons at centers of excellence should aim for repair of both anterior and posterior leaflet pathology with the same decision-making threshold over valve replacement.

Summary: This study evaluates the mid-term results of mitral valve repair with patch augmentation of the posterior leaflet in patients with secondary mitral regurgitation. The results show that the augmentation technique, combined with remodelling annuloplasty, is a safe and reproducible method for mitral valve reconstruction, providing sustainable competence.

Summary: Mitral regurgitation due to bileaflet prolapse can be corrected by reducing the height of the posterior leaflet, with no recurrence observed during follow-up in patients who underwent this type of repair.

Summary: Mitral valve prolapse (MVP) is a common condition affecting 2-3% of the general population, with a complication rate up to 10-15% per year. Complications include mitral regurgitation, heart failure, atrial fibrillation, ventricular arrhythmia, and cardiovascular death. MVP can be syndromic or non-syndromic, and the genetic defects associated with MVP are still being studied. Animal models are used to advance the understanding of MVP genetics and pathophysiology. Genetic counseling is important in managing patients with MVP.

Summary: This study compared the long-term outcomes of quadrangular resection and inverse plication for posterior leaflet prolapse. The results showed no significant differences between the two surgical methods in terms of patient age, sex, procedural times, and hospitalization time. However, the inverse plication group had significantly lower long-term mortality compared to the quadrangular resection group. Therefore, inverse plication can be a safe and effective alternative to quadrangular resection.

Summary: This meta-analysis compares the long-term outcomes of anterior/bi-leaflet mitral valve repair and isolated posterior leaflet repair in patients with mitral regurgitation due to degenerative mitral valve disease. The results showed no significant difference in long-term survival, freedom from moderate-to-severe MR, and freedom from re-operation between anterior/bi-leaflet repair and posterior leaflet repair.

Summary: The study introduces a double-leaflet technique that creates a new autologous pericardial leaflet on small or tethered posterior leaflets, improving the outcomes of mitral valve repair surgery.

Summary: This study compared the effects of leaflet resection and preservation techniques on left ventricular reverse remodeling after mitral repair, and found that these strategies did not significantly influence the remodeling trends.

Summary: Preoperative transthoracic echocardiography is essential for determining the type and severity of valve disease, while transesophageal echocardiography is selectively used when surgery is uncertain. Intraoperative transesophageal echocardiography is routinely used to aid in reducing valve regurgitation under anesthesia.

Summary: A 68-year-old male presented with fever for two weeks, and investigations revealed mitral valve endocarditis caused by Staphylococcus epidermidis, with severe mitral regurgitation. The patient was scheduled for mitral valve surgery but developed new neurological symptoms two days prior, being diagnosed with symptomatic epilepsy. Kissing lesions were found during surgery on the posterior mitral leaflet, which were not detected on preoperative transesophageal echocardiography. This case highlights the importance of careful examination during surgery and prompt diagnosis and treatment of infective endocarditis for successful outcomes.

Summary: The study compared quadrangular leaflet resection with chordal replacement for degenerative posterior mitral leaflet prolapse repair, finding that patients with multiple leaflet prolapse were more likely to undergo chordal replacement. Surgical technique was not an independent risk factor for recurrent severe MR.

Summary: Functional mitral stenosis after mitral valve repair is associated with increased risk of new-onset atrial fibrillation, MV reoperation, and decreased long-term survival. A small left ventricle and annuloplasty ring are independent risk factors for functional MS.
