MRI Snapshot of MAD

Indian Journal of Clinical Cardiology
Mitral annular disjunction is a structural abnormality characterized by atrial displacement of the mitral valve annulus or leaflet hinge point away from the ventricular myocardium. This anomaly is frequently associated with mitral valve prolapse, leaflet

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, 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.

Bachmann's Bundle‐Related Atrial Tachycardias Following Catheter Ablation of Persistent Atrial Fibrillation

Journal of Cardiovascular Electrophysiology, Volume 37, Issue 3, Page 561-571, March 2026.
ABSTRACT Background Atrial tachycardias (AT) after radiofrequency ablation (RFA) of atrial fibrillation (AF) may utilize Bachmann's bundle (BB). Due to their epicardial location, these ATs remain poorly understood. Objective To describe the electrophysiologic and anatomic basis of BB‐related ATs.

A Review of Nanoparticle‐Based Astrocyte Modulation in CNS Disorders: Evaluating the Underexplored Potential of Intranasal Delivery

Nano Select, Volume 7, Issue 1, January 2026.
Nanoparticle‐driven nose‐to‐brain drug delivery offers a noninvasive approach to bypass the blood–brain barrier (BBB) and directly modulate reactive astrocytes in CNS disorders. This review highlights biodegradable nanoparticles for astrocyte modulation, enhancing drug bioavailability, sustained release, and neuroinflammation control.

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.

Postpump Chorea After Pediatric Cardiac Surgery: Exploring Causes and Treatment

Journal of Cardiac Surgery, Volume 2026, Issue 1, 2026.
Introduction Postpump chorea is a rare but potentially disabling movement disorder that arises days to weeks after cardiopulmonary bypass, most often following deep hypothermic circulatory arrest in pediatric patients undergoing repair of complex congenital heart defects. Clinically, postpump chorea presents as involuntary, nonrhythmic, choreiform, and
