Understanding Transseptal Procedures in Cardiology

Transseptal refers to a structure or procedure that crosses the septum, which is a thin membrane that separates the left and right sides of the heart. In cardiology, transseptal procedures are used to access the left side of the heart from the right side, or vice versa.

For example, a transseptal puncture is a technique used to gain access to the left side of the heart through the septum, allowing for the insertion of catheters or other devices for diagnostic or therapeutic purposes. A transseptal approach can also be used during certain types of heart surgery, such as when repairing a hole in the septum.

In general, the term "transseptal" is used to describe any procedure or structure that crosses the septum, and it is often used in conjunction with other terms, such as "transseptal catheterization" or "transseptal implantation," to specify the specific type of procedure being performed.
