Functional conduction system mapping in sheep reveals Purkinje spikes in the free wall of the right ventricular outflow tract

Frontiers in Physiology
Ablation of sites displaying Purkinje activity is highly effective against idiopathic ventricular fibrillation which often originates in the right ventricular outflow tract.

Idiopathic left ventricular outflow tract pseudoaneurysm

Annals of Cardiac Anaesthesia, 2013
Left ventricular outflow tract (LVOT) pseudoaneurysm is a rare occurrence and may produce clinically unpredictable symptoms. A very few cases of LVOT pseudoaneurysm are reported and there has always been a predisposing factor in these reported cases such as history of infective endocarditis, myocardial infarction, prosthetic aortic valve replacement or

Prevention of LVOT Obstruction by Device-Mediated Laceration of the Anterior Mitral Valve Leaflet During TMVR

JACC: Case Reports, 2023
Left ventricular outflow tract obstruction represents a life-threatening complication in patients undergoing transcatheter mitral valve replacement. Interventional approaches to prevent left ventricular outflow tract obstruction are complex and require ...

Ventricular, atrial, and outflow tract heart progenitors arise from spatially and molecularly distinct regions of the primitive streak

bioRxiv, 2020
The heart develops from two sources of mesoderm progenitors, the first and second heart field (FHF and SHF). Using a single cell transcriptomic assay in combination with genetic lineage tracing, we find the FHF and SHF are subdivided into distinct pools ...
