A left atrial (LA) line monitors left atrial pressures acting as a surrogate for left ventricular function, preload and afterload. The left atrial line enters from the left superior pulmonary vein and exits the far side of the chest.
The left atrial line is a single lumen catheter unlike the right atrial line, which is double lumen. Normal left atrial pressure values are 4-12 mmHg.
