Transcatheter Edge-to-Edge Repair for Mitral Valve Systolic Anterior Motion in Complex Left Ventricular Outflow Tract Phenotypes: A Case Series

Journal of the Society for Cardiovascular Angiography & Interventions
Dynamic left ventricular outflow tract obstruction due to systolic anterior motion of the mitral valve can arise across diverse anatomic substrates. We report 5 consecutive patients with systolic anterior motion–mediated left ventricular outflow tract ...

Physiological and clinical consequences of relief of right ventricular outflow tract obstruction late after repair of congenital heart defects. [PDF]

, 2006
BACKGROUND: Right ventricular outflow tract obstruction (RVOTO) is a common problem after repair of congenital heart disease. Percutaneous pulmonary valve implantation (PPVI) can treat this condition without consequent pulmonary regurgitation or ...

Non-pharmaceutical Interventions for Hypertrophic Cardiomyopathy: A Mini Review

Frontiers in Cardiovascular Medicine, 2021
Hypertrophic cardiomyopathy is an inherited cardiovascular disease, and 70% of patients have left ventricular outflow tract obstruction. Ventricular septal myectomy has been the gold standard treatment for most patients with refractory symptoms.

A Spatiotemporal Single‐Cell Atlas Uncovers Dysregulated ECM Dynamics and Septal Remodeling Arrest in Human Ventricular Septal Defects

Advanced Science, EarlyView.
Integrating single‐cell and spatial transcriptomics reveals human ventricular septal defect (VSD) as a disease of microenvironmental insufficiency and structural remodeling arrest. Attenuated endothelial‐fibroblast crosstalk, alongside downregulated THBS1/TGF‐β1 and MMP2 signaling networks, impairs the endothelial‐to‐mesenchymal transition (EndoMT) and
