: Pre-operative identification of a prominent Eustachian Valve (EV) is critical before surgical repair of defects like Atrial Septal Defects (ASD) or VSD . Misidentifying the EV can lead to inadvertent suturing and obstruction of the Inferior Vena Cava (IVC).

: The Voltage Sensor Domain (VSD) undergoes outward translation and rotation to couple with the pore module, facilitating the opening of ion channels.

: A common congenital heart defect involving a hole in the wall (septum) separating the heart's lower chambers.

: Multimodality imaging, including echocardiography and CT, is used to diagnose post-operative complications and accurately map cardiac anatomy.

The search results for "Vsd 25 Ev mp4" point toward medical and biological contexts involving cardiac anatomy and cellular mechanisms, though they do not reference a specific "mp4" file. The acronyms likely refer to:

: In cellular biology, this refers to a domain in ion channels (like NaV1.8cap N a sub cap V 1.8 BKcap B cap K channels) that responds to changes in membrane potential. Key Clinical Information
