Mitral valve cleft is a rare entity. However, it must be recognized as a differential mechanism for mitral valve regurgitation. 3D transesophageal echocardiography plays an essential role in the evaluation of single and multiple mitral valve clefts, improving morphological and functional assessment of the valve, with potential implications on surgical planning. The authors present four rare cases of mitral valve cleft presenting during adulthood, followed by a mini-review about the role of 3D echocardiography, as well as its pitfalls, in the assessment of this complex congenital mitral valve disease.

Background: Sudden cardiac arrest (SCA) risk stratification in patients with mitral valve prolapse (MVP) may be complicated by other potential causes of arrhythmia.

Objectives: We aimed to characterize SCA survivors with isolated (iMVP) and non-isolated MVP (non-iMVP) and to assess their long-term follow-up.

Methods: This ambispective study included 75 patients with MVP who experienced SCA and were treated in our center between 2009-2024.

BACKGROUND Primary cardiac malignancies are extremely rare, with an incidence of 0.07% on autopsy series. Primary sarcomas represent up to 95% of malignant neoplasms, with myxofibrosarcomas accounting for only 10%.

Background: Referred to as the "forgotten chamber," the right ventricle (RV) is now widely acknowledged as a significant factor, particularly in certain cardiovascular pathologies. Despite historically being undervalued in comparison to the left ventricle, the RV function is deemed crucial in determining patient outcomes following mitral valve (MV) surgery. In the context of MV surgery, it is important to note that the RV is highly susceptible to dysfunction before, during, and after the surgical procedure.

Department of Cardiac Surgery, Smidt Heart Institute, Cedars-Sinai Medical Center, Los Angeles, California, USA.

Purpose Of Review: Over the past 25 years, robotic-assisted mitral valve surgery has gained significant recognition because of its potential to minimize patient trauma and improve clinical outcomes. This field has evolved from early efforts in minimally invasive mitral procedures to more refined and technically sophisticated approaches, driven by the need for smaller incisions and reduced recovery times.

Recent Findings: This review will delve into the historical evolution of robotic-assisted mitral valve surgery, detailing the technical advancements that have shaped current practices and outlining the essential training pathways for a career as robotic mitral valve surgeon.
