Men

Wikipedia article Longest tiebreaker in tennis (current revision) lists 52 points (27-25) from the match between Bury/Kowalczyk and Dasnières de Veigy/Gicquel in the first round of 2012 Marrakech challenger. However, this was at ATP Challenger Tour, not at ATP World Tour level.

The longest supertiebreak at an ATP tournament seems to be 44 points (23-21) from the match between Montañés/Ramírez Hidalgo and Aspelin/Čermák in the first round of 2007 Estoril Open.
