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

Comparative multimodal calibration of patient‐specific atrial fibrillation models: Impact of imaging and electrophysiology data on arrhythmogenic substrate identification

The Journal of Physiology, EarlyView.
Abstract figure legend Comparative multimodal calibration of patient‐specific left atrial (LA) models to identify arrhythmogenic substrates in atrial fibrillation (AF). A, LA models shown in posterior and anterior views, calibrated separately using: late gadolinium enhancement magnetic resonance imaging (LGE‐MRI) image intensity ratio (IIR; blue–red ...

Case Report: Selective metal cell excision during open TAVR implantation preserves coronary access while maintaining valve integrity and function

Frontiers in Medicine
BackgroundCoronary access following transcatheter aortic valve replacement (TAVR) remains challenging and should be carefully considered when planning re-intervention for patients with structural valve degeneration.

Regional electrical differences and arrhythmia in the rat atria: Role of sympathetic nerve distribution and function

The Journal of Physiology, EarlyView.
Abstract figure legend Atrial fibrillation commonly develops in the left atrium and pulmonary veins (PVs), and can be triggered by sympathetic nerve activity. Here, we examined regional atrial differences in sympathetic nerve distribution and function in the rat.

Pregnancy does not accelerate biological valve degeneration.

, 2010
Pregnancy in women with biological heart valve prosthesis might lead to a faster degeneration of the prosthesis. We analyzed the rate of prosthesis replacement and the outcome of pregnancies in women with biological valve prosthesis.Between 1976 and 2006,

Mitral regurgitation and decompensated heart failure in a young pregnant pony mare: An aetiological challenge

Equine Veterinary Education, Volume 38, Issue 10, Page e676-e685, October 2026.
Summary A 4‐year‐old, 6‐month pregnant, Welsh pony mare presented with severe acute clinical signs including depression, anorexia, pale mucous membranes, tachycardia with a grade 4/6 holosystolic murmur and moderate expiratory dyspnoea with diffuse wheezes. There was no evidence of placentitis or fetal distress.

Smaller Bioprosthetic Valves May Be Associated with Worse Clinical Outcomes and Reduced Freedom from Reoperation in sAVR

Journal of Cardiovascular Development and Disease
Background: Surgical bioprosthetic aortic valve replacement is a ubiquitous procedure, with several factors identified in affecting outcomes. We hypothesize that smaller valves may be associated with worse outcomes and decreased freedom from clinical ...

CO2 Activation by Small Copper, Cobalt, and Yttrium Oxide Clusters Probed via Infrared Multiple‐Photon Dissociation Spectroscopy

ChemPhysChem, Volume 27, Issue 17, 14 September 2026.
Infrared multiple photon dissociation spectroscopy is used to study the activation of CO2 on Cu‐, Co‐, and Y‐oxide clusters. While CO2 activation is not possible on cationic clusters, the binding motif on anionic clusters depends on a fine interplay between the nature and energetic location of the molecular orbitals and the charge (oxidation state) on ...

Chiral Porphyrin Monolayers on Ferromagnetic Thin Films: Ultrafast Spectroscopy of Hybrid Interfaces

Advanced Optical Materials, Volume 14, Issue 33, 4 September 2026.
Chiral porphyrin–oligopeptide monolayers covalently bound to Au‐capped Co/Ni multilayers form surface‐parallel J‐type aggregates and exhibit measurable singlet‐state transient absorption despite monolayer coverage. Femtosecond pump–probe spectroscopy reveals strong excited‐state quenching at the metal interface, yet no long‐lived charge‐transfer ...
