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).

Mitral annular disjunction with atrial septal defect in children: An intriguing association

Annals of Pediatric Cardiology
Mitral annular disjunction (MAD) is defined as a separation between the mitral annulus and the left ventricular myocardium and is most often seen in association with mitral valve prolapse (MVP).

Cardiac MRI Across ESC Guidance in the Last Decade

Clinical Cardiology, Volume 49, Issue 5, May 2026.
CMR: bridging clinical challenges to guideline solutions. Four panels summarise the role of cardiovascular magnetic resonance (CMR) in ESC guidance. Abbreviations: CMR = cardiovascular magnetic resonance. ESC = European Society of Cardiology. MINOCA = myocardial infarction with non‐obstructive coronary arteries. RV = right ventricle.

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.

The added value of three-dimensional transthoracic echocardiography in mitral annular disjunction: a case report

Frontiers in Cardiovascular Medicine
BackgroundMitral annular disjunction (MAD) refers to the arrhythmic mitral valve prolapse (MVP) syndrome associated with ventricular arrhythmias and sudden cardiac death. Although the pathophysiology of this disease is still under investigation, specific

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.

Near‐Fatal Arrhythmia From Severe Mitral Annular Disjunction

Case Reports in Cardiology, Volume 2026, Issue 1, 2026.
Mitral annular disjunction (MAD) is increasingly recognized as a structural abnormality associated with ventricular arrhythmias and sudden cardiac arrest, particularly in the setting of bileaflet mitral valve prolapse (MVP). A 43‐year‐old man with a history of migraines presented following a witnessed out‐of‐hospital cardiac arrest and was successfully

Arrhythmic Mitral Valve Prolapse with Features of Mitral Annular Disjunction and Myocardial Tissue Changes as Assessed with Cardiac Magnetic Resonance

Majalah Kardiologi Indonesia
Background. Mitral valve prolapse (MVP) is a rare disorder linked to abrupt cardiac mortality and malignant ventricular arrhythmias. Beyond conventional prognostic indicators, risk stratification may have a promising function in MVP patients, as cardiac

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

Outcomes of Non‐Paroxysmal AF Undergoing Ablation Guided by a Novel High‐Density Panoramic Cycle‐Length Mapping System

Pacing and Clinical Electrophysiology, Volume 48, Issue 12, Page 1424-1433, December 2025.
ABSTRACT Background Catheter ablation is a current therapeutic approach for atrial fibrillation (AF). However, the efficacy for non‐paroxysmal AF remains suboptimal. Objective We hypothesize that the novel panoramic cycle‐length mapping (CLM) system can guide the pulmonary vein (PV) isolation and additional potential AF drivers.
