Single coronary ostium in a patient with quadricuspid aortic valve combined with aneurysmal ascending aortic dilatation

Journal of Cardiothoracic Surgery, 2017
Background The presence of a fourth aortic valve cusp (quadricupsid aortic valve) is a rare congenital malformation and is often accompanied by other anomalies of the adjacent cardiovascular structures.

Single‐Cell Mitochondrial Lineage Tracing Decodes Fate Decision and Spatial Clonal Architecture in Human Hematopoietic Organoids

Advanced Science, EarlyView.
This study repurposes mitochondrial DNA mutations as endogenous barcodes for lineage tracing in human pluripotent stem cell‐derived organoids. Integrated with transcriptomic and spatial data, it reveals NOTCH‐mediated stromal‐progenitor crosstalk orchestrates clonal dynamics and spatial zonation during early hematopoietic development, offering a non ...

Surgical Explantation of Transcatheter Aortic Valve Requires Patient-Tailored Management, but Challenges Remain

Journal of Cardiovascular Development and Disease
Transcatheter aortic valve replacement has become a widely accepted alternative to surgical aortic valve replacement even in younger, lower-risk patients with longer life expectancy. The increasing use of transcatheter aortic valve replacement is leading

Endothelial GPR68 Is Essential for Arteriogenesis and Represents a Therapeutic Target in a Model of Peripheral Artery Disease

Advanced Science, EarlyView.
Endothelial GPR68 is identified as a critical regulator of collateral artery growth in peripheral artery disease. Genetic and pharmacological evidence demonstrates that GPR68 integrates hemodynamic cues to drive monocyte recruitment and inflammatory remodeling, thereby promoting collateral arteriogenesis and tissue perfusion after ischemia ...
