Correlation between Myocardial Velocity Measured using Tissue Doppler Imaging in the Left Ventricular Lead-Implanted Segment and Response to Cardiac Resynchronization Therapy

Clinics
OBJECTIVES: This study investigated whether tissue Doppler imaging parameters, especially the peak systolic velocity of the left ventricular lead-implanted segment (Ss), affect cardiac resynchronization therapy response.

Successful pregnancies after transvenous cardiac resynchronization therapy in a woman with congenitally corrected transposition of the great arteries

The Egyptian Heart Journal, 2017
Congenitally corrected transposition of the great arteries is a rare heart defect that can be associated with systemic ventricular dysfunction and conduction disturbances.

The influence of delayed ventricular activation on cardiac repolarization: Insights from electrocardiographic imaging

The Journal of Physiology, EarlyView.
Abstract figure legend This study examines the relationships between activation and repolarization times in epicardial reconstructed unipolar electrograms derived from ECG‐imaging in patients with normal and delayed ventricular activation. In patients with a narrow QRS‐complex, ECG‐imaging reveals significant variability in the activation ...

Repolarization adaptation to rapid change in heart rate in human models – a review

The Journal of Physiology, EarlyView.
Abstract figure legend This review focuses on non‐invasive assessment of repolarization duration and dispersion (heterogeneity) adaptation to change in heart rate (HR). HR was increased incrementally by left atrial pacing during an electrophysiology (EP) study and by a bolus injection of atropine and in a step up/down fashion by repeated right atrial ...

Panoramic voltage‐sensitive optical mapping of contracting hearts using cooperative multiview motion tracking with 12 cameras

The Journal of Physiology, EarlyView.
Abstact figure legend A panoramic 3D optical mapping system was developed, enabling imaging of action potential waves across the entire strongly deforming ventricular surface of beating isolated hearts. The system comprises 12 high‐speed cameras and a soccerball‐shaped imaging chamber with 48 light‐emitting diodes (LEDs).

The anti‐fibrotic effects of novel heart failure pharmacotherapies in advanced heart failure patients

British Journal of Pharmacology, Volume 183, Issue 7, Page 1502-1516, April 2026.
Background and Purpose Novel heart failure (HF) pharmacotherapies, including angiotensin receptor‐neprilysin inhibitor (ARNI) and sodium‐glucose cotransporter 2 inhibitors (SGLT2is), may confer cardiovascular benefits by attenuating myocardial fibrosis. However, direct evidence from human failing myocardial samples is limited.

Transcatheter Left Ventricular Restoration in Ischemic Heart Failure and Dilated Cardiomyopathy

Catheterization and Cardiovascular Interventions, Volume 107, Issue 4, Page 898-908, March 1, 2026.
ABSTRACT Ischemic heart disease is the leading global cause of death and frequently progresses to ischemic heart failure (IHF) after myocardial infarction through adverse left ventricular (LV)remodeling. Surgical LV restoration improves ventricular geometry and function but is limited by invasiveness and inconsistent outcomes.
