Beat‐to‐beat variability of ventricular repolarization reveals sex‐specific instability and proarrhythmic risk

The Journal of Physiology, EarlyView.
Abstract figure legend A mechanistic framework linking sex‐dependent dynamical instability to proarrhythmic risk. Sex‐specific human ventricular models show that upstream modulators, including biological sex, hormones, drugs and heart disease, promote steeper APD restitution in female than male and enhance dynamical instability.

Ventricular septal defect and left ventricular outflow tract obstruction after transcatheter aortic valve implantation

, 2018
: Ventricular septal defect (VSD) has been reported as a rare complication after transcatheter aortic valve implantation (TAVI), presenting with signs of heart failure. Furthermore, left ventricular outflow tract obstruction (LVOTO) may worsen after TAVI,

Transient Atrioventricular Block Secondary to Coronary Artery Embolism From Infective Endocarditis Following CAR T‐Cell Therapy

Journal of Arrhythmia, Volume 42, Issue 6, December 2026.
Silent infective endocarditis after CAR‐T therapy caused septic embolic occlusion of a septal coronary branch, producing localized myocardial infarction involving the His bundle region and transient complete atrioventricular block. This case highlights a rare, pathologically confirmed mechanism of conduction disturbance.
