Accelerating Mission Engineering: Evidence of a Stratified Landscape and a Path Toward Unified Practice

Systems Engineering, EarlyView.
ABSTRACT Mission Engineering is maturing as a Systems Engineering discipline, yet adoption of its common frameworks remains stratified. This study examines whether selective adoption is observable across ME scholarship and develops a framework to address identified barriers.

Mitral annular disjunction in advanced myxomatous mitral valve disease: echocardiographic detection and surgical correction

, 2005
Mitral annular disjunction is a structural abnormality of the mitral annulus fibrosus described by pathologists in association with mitral leaflet prolapse and defined as a separation between the atrial wall-mitral valve (MV) junction and the left ...

Mitral annular disjunction identified peripartum : a case highlighting key features of a recently classified syndrome

, 2023
Mitral annular disjunction (MAD) is the displacement of the mitral annulus hinge point from the left ventricular myocardium. MAD, which was first recognised in 1986,1 is of unconfirmed aetiology and was only classified as a syndrome in 2018.2 The ...

Modified Anatomical Ablation Strategy for Mitral Isthmus

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background Durable mitral isthmus (MI) block remains challenging in persistent atrial fibrillation (AF) ablation. Ethanol infusion into the vein of Marshall (EI‐VOM) enhances efficacy, but the minimal endocardial ablation extent post‐EI‐VOM is undefined.

Dual nature of mitral annular disjunction: normal variation or pathological precursor?

Hellenic Journal of Cardiology
The concept of mitral annular disjunction (MAD) has garnered significant attention due to its potential clinical implications. MAD refers to a spatial displacement of the hinge point of the mitral valve leaflets.

Association of Mitral Annular Disjunction on Magnetic Resonance Imaging With Cardiovascular Outcomes

European Journal of Clinical Investigation, Volume 56, Issue 6, June 2026.
In 1969, consecutive patients undergoing CMR, MAD was assessed in end‐diastole and end‐systole across 2‐, 3‐, and 4‐chamber views (panels A–F, lower left), and native T1 relaxation times were measured at the mitral annulus (upper left, T1 colour map).

Arrhythmogenic Mitral Valve Prolapse and Mitral Annular Disjunction: a Literature Review and Case-Based Perspective (Russian Translation)

Juvenis Scientia
Mitral valve prolapse (MVP) is among the most frequently diagnosed valvular heart diseases, with the majority of patients being asymptomatic. However, MVP may also present with ventricular arrhythmias (VA) or sudden cardiac death (SCD).

Prevalence of Mitral Annular Disjunction at Cardiac MRI: Results from a Multicenter Registry. [PDF]

Radiol Cardiothorac Imaging
Mitral annular disjunction (MAD) was a frequent incidental finding at cardiac MRI examinations performed for various clinical indications; longer MAD length and coexisting bileaflet mitral valve prolapse were associated with a higher prevalence of ...
