A surgical procedure for atrial fibrillation, in which the right and left pulmonary veins are isolated and the left atrial appendix is surgically removed. Incisions are made to disrupt the irregular fibrillatory flow of electricity through the atrium, constructing a path shaped like a labyrinth, which directs energy solely from the sinoatrial node to the atrioventricular node. The procedure is often performed during other heart surgeries, e.g., coronary artery bypass grafting.

ABBR: PNP A laboratory procedure to determine the presence of a lupus anticoagulant in a blood sample.
