A Novel Transcatheter Posterior Ventricular Anchoring Neochordoplasty Mitral Valve Repair Device.

Purpose: Advancements in minimally invasive technologies to decrease postoperative morbidity and recovery times represent a large opportunity for mitral valve repair operations. However, current technologies are unable to replicate gold standard surgical neochord implantation.
Methods: We developed a novel neochordal repair device, Minimally Invasive Ventricular Anchoring Neochordoplasty (MIVAN), which operates via transcatheter, trans-septal anchoring to the posterior ventricular wall.

Article Synopsis
- Atrial secondary tricuspid regurgitation (A-STR) is a subtype of secondary tricuspid regurgitation (STR) that is often treated with transcatheter tricuspid valve edge-to-edge repair (T-TEER), showing distinct patient characteristics and treatment outcomes.
- A study involving 641 patients revealed that 31% had A-STR, which was linked to better heart function, a higher presence of atrial fibrillation, and more effective TR reduction post-procedure compared to nonatrial STR patients.
- A-STR patients experienced improved survival rates and lower symptomatic burdens after treatment; only 38% remained symptomatic (NYHA class ≥III) after 2 years, compared to 46
Morphological Characteristics of Interatrial Septum and Its Clinical Relevance.
Catheter Cardiovasc Interv
December 2024
Department of Anatomy, Hind Institute of Medical Sciences, Barabanki, India.
Background: The development of new trans-septal transcatheter interventions for patients with structural heart disease necessitates a precise and comprehensive understanding of the anatomy of the interatrial septum (IAS). The scarcity of gross anatomical studies has triggered our interest in exploring the morphometry and morphology of IAS.
Aims: To study the morphology, morphometry and variations of the interatrial septum in autopsied human hearts.
Successful Transcatheter Mitral Valve Mass Extraction With Complete Resolution of the Severe Mitral Regurgitation.

Interest has arisen in exploring the off-label application of left-sided percutaneous mechanical aspiration, where conventional management strategies may not suffice. Percutaneous mechanical aspiration has been shown to be effective as a diagnostic and therapeutic intervention in select patients with infective endocarditis. This paper hereby reports the first case of a successful transeptal large bore manual aspiration device (AlphaVac; Angiodynamics) for nonbacterial thrombotic endocarditis with total resolution of associated severe mitral valve regurgitation.
