Changes in left atrial deformation in hypertrophic cardiomyopathy: Evaluation by vector velocity imaging. [PDF]

, 2012
OBJECTIVES: Hypertrophic cardiomyopathy (HCM) represents a generalized myopathic process affecting both ventricular and atrial myocardium. We assessed the global and regional left atrial (LA) function and its relation to left ventricular (LV) mechanics ...

Left Ventricular Outflow Tract Geometry as a Predictor of Permanent Pacemaker Implantation After Transcatheter Aortic Valve Implantation Using the Evolut Series

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Predicting the need for permanent pacemaker implantation (PPM) after transcatheter aortic valve implantation (TAVI) is crucial for procedural planning and patient counseling. Aims To evaluate whether left ventricular outflow tract (LVOT) morphology, specifically a tapered configuration, predicts conduction disturbances requiring PPM

Metabolic changes during cardiac regeneration in the axolotl

Developmental Dynamics, EarlyView.
Abstract Background The axolotl is a prominent model organism of heart regeneration due to its ability to anatomically and functionally repair the heart after an injury that mimics human myocardial infarction. In humans, such an injury leads to permanent scarring. Cardiac regeneration has been linked to metabolism and the oxygenation state, but so far,

Lineage labeling with zebrafish hand2 Cre and CreERT2 recombinase CRISPR knock‐ins

Developmental Dynamics, EarlyView.
Abstract Background The ability to generate endogenous Cre recombinase drivers using CRISPR‐Cas9 knock‐in technology allows lineage tracing, cell type‐specific gene studies, and in vivo validation of inferred developmental trajectories from phenotypic and gene expression analyses. This report describes endogenous zebrafish hand2 Cre and CreERT2 drivers

Expression of mutant TIE2 p.L914F during mouse development causes embryonic lethality and defects in vascular remodeling

Developmental Dynamics, EarlyView.
Abstract Background Sporadic venous malformation (VM) is associated with the hyperactivating p.L914F mutation in TIE2, a receptor tyrosine kinase essential for vascular development. This mutation is not found in hereditary VM, suggesting incompatibility with life when expressed during early vascular development.

Acquired discrete subaortic stenosis late after mitral valve replacement

Indian Heart Journal, 2016
Although acquired left ventricular outflow obstruction has been reported in a variety of conditions, there are scant reports of its occurrence following mitral valve replacement (MVR).

Left ventricular diastolic dysfunction worsens prognosis in patients with heart failure due to dilated cardiomyopathy

ESC Heart Failure, Volume 12, Issue 2, Page 1183-1193, April 2025.
Abstract Aims The prognostic significance of left ventricular (LV) diastolic dysfunction (LVDD) severity in patients with dilated cardiomyopathy (DCM) remains uncertain. This study aimed to evaluate the association of LVDD severity and elevated left atrial pressure (eLAP) with patient outcomes in stable, non‐acutely decompensated patients with DCM ...

Surgical removal of a left ventricular myxoma in an infant

Annals of Pediatric Cardiology, 2013
Left ventricular (LV) myxoma is particularly rare in children and has not been reported in infants. A five-month-old baby presented with a myxoma arising from the anterior, lateral, and superior aspect of the LV, causing severe left ventricular outflow ...
