Portland Trail Blazers forward LaMarcus Aldridge underwent a successful procedure Friday to evaluate the status of the electrical system in his heart.

Aldridge, who was diagnosed with Wolff-Parkinson-White Syndrome in 2007, will be sidelined for 5-7 days before he can return to practice. He underwent a similar procedure to correct the problem at the time of diagnosis four years ago.

The 26-year-old Aldridge has career averages of 17.3 points and 7.5 rebounds in 379 games (338 starts). He averaged a team-high 21.8 points to go with 8.8 rebounds in 81 games last season.
