Trans-septal monitoring of left atrial pressure after cardiac surgery. An alternative method.

A simple, safe method for trans-septal insertion of a left atrial pressure line in 25 patients is presented. Complications have not been noted. Monitoring of left atrial pressure is often desirable after cardiac surgery. The conventional lateral approach is associated with the risk of haemorrhage after the cannula has been withdrawn. In an oversensitive heart manipulation might not be tolerated, precluding placement of the cannula.
