Does Anatomic Phenotype of Mitral Annular Disjunction Impact Survival? An Autopsy-Based Retrospective Study

Journal of Cardiovascular Development and Disease, 2021
Controversies have been raised regarding the prevalence and potential clinical significance of mitral annular disjunction (MAD). We aim to address the anatomic characteristics of MAD and their association, if any, on survival. We retrospectively reviewed

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.

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.

Ventricular Tachycardia Ablation in Structural Heart Disease With LVEF > 35%: Clinical Outcomes and Recurrence Patterns

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background In patients with structural heart disease (SHD) and moderately impaired left ventricular ejection fraction (LVEF > 35%), data on outcomes after ventricular tachycardia (VT) ablation remain limited. This analysis focuses on VT recurrence after ablation in patients presenting with sustained VT and LVEF > 35% within a secondary ...

Arrhythmic Mitral Valve Prolapse and Mitral Annular Disjunction: Clinical Features, Pathophysiology, Risk Stratification, and Management

Journal of Cardiovascular Development and Disease, 2022
Mitral valve prolapse (MVP) is a common cause of valvular heart disease. Although many patients with MVP have a benign course, there is increasing recognition of an arrhythmic phenotype associated with ventricular arrhythmias and sudden cardiac death ...

Modified Anatomical Ablation Strategy for Mitral Isthmus

Pacing and Clinical Electrophysiology, Volume 49, Issue 8, Page 1159-1167, August 2026.
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.

Brain sparing in fetal growth restriction: The double‐edged sword of fetal hypoxaemia

The Journal of Physiology, Volume 604, Issue 15, Page 6259-6280, 1 August 2026.
Abstract figure legend The double‐edged sword of brain sparing. Fetal hypoxaemia triggers a coordinated adaptive response characterised by redistribution of cardiac output toward essential organs, including the brain, and a reduction in overall metabolic activity to preserve oxygen supply.

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).

Case report: Aborted sudden cardiac death as a first presentation of severe mitral annulus disjunction—a case series and review of the literature

Frontiers in Cardiovascular Medicine, 2023
Mitral annulus disjunction (MAD) is defined as a systolic displacement between the ventricular myocardium and the posterior mitral annulus supporting the posterior mitral leaflet.
