Narrative:
During descent while slowing to 250 KIAS above 10;000 feet; ECAM alert alerted 'left window heat'. Shortly [thereafter] the first officer heard a slight 'crack' and noticed that the fixed side window on the captain's side was cracked in a spider web pattern. There were no other indications. Descent was continued to a normal landing. Dispatch and maintenance were advised. A left window heat system fault may have contributed to thermal shock; causing the window to fracture.
