Turn left and the UCLA Luskin Conference Center, a premiere Los Angeles meeting venue and hotel, is located one mile ahead at end of the turnaround.

Can I present my scientific data on hemodynamics or collaterals at the meeting?

Yes. Electronic posters and abstracts will be viewable on our website, providing an opportunity to showcase your latest data on the topic.

Can I get certificate of attendance?

Yes. Certificates of attendance can be provided upon request.

What about parking?

Self-parking is available underneath the Luskin Conference Center and in UCLA Parking Structure 8, Level 4, directly across the street from the Center. There is a convenient Pedestrian Walkway/Bridge connecting Parking Structure 8 (on Level 3) to the Los Angeles Conference Center property. There is a daily fee to park in either location.
