Family
Vyatchanin came from a swimming family and was initially trained by his aunt, father and mother, who were all retired competitive swimmers and professional swimming coaches.

Vyatchanin is married to Evgeniya.

Change of nationality
In 2013 Vyatchanin announced an intention to leave the Russian team and compete for another country saying he gave all he could to team Russia. In 2015 he obtained Serbian citizenship (name in Arkadij Vjatčanjin), but could not complete internationally because of administrative errors in his international transfer. Hence he missed the 2016 Summer Olympics. In 2017 Vyatchanin obtained American citizenship. He retired in June 2018 aiming to become a swimming coach.
