Narrative:
In cruise flight; with no warning; a very loud 'crash' sounded behind me to my left. Upon turning around; I and the first officer observed the rear window completely shattered. I and he immediately went on O2 and rechecked sear-belt integrity. I subsequently got an immediate decent to FL190 at which time we complied with QRH procedures and lowered delta-P to 4.8 psi. The inner pane of glass was found to be completely intact. An anti-ice ECAM had appeared after the fact which we complied with as well. Seat belt sign was immediately put on and I made a PA to have flight attendant's cease service and buckle-up. Once established at FL190; I allowed flight attendant's to unbuckle but not serve. Seat belt sign was left on to landing as a precaution. We were later given an altitude restriction which we were going to be very tight on as we started down late. We were given a heading and a new altitude with a change of centers. [There] appeared to be no conflicts. Attention to the window and current operations led to the late departure from FL190 to 12;000 ft. We probably would have made the restriction; but I informed center as a precaution. [There was an] anti-ice malfunction on that window.
