Left atrial line

The left atrial (LA) line monitors LA pressure and is indicative of left ventricular function, preload and afterload. The LA line enters from the left superior vein and exits the far side of the chest.

The LA line is a single lumen catheter unlike the right atrial line, which is double lumen. Normal LA values are 4-12 mmHg.
