He was slain in battle by the Gangas leaving no heirs to the Pallava throne.
During his reign, the Pallava capital Kanchi was attacked by the Chalukyas and their Ganga allies and Paramesvaravarman had to surrender and accept humiliating conditions.
To avenge this humiliation, Paramesvaravarman subsequently attacked the Gangas but was defeated and killed in battle.
Ugrodhaya (A neck ornament) was taken from him and the Ganga King assumed the title Permanadi.
Following Paramesvaravarman's death in 731, the Simhavishnu line of Pallavas became extinct.
