Logo needed for community website of healthcare professionals

HeartTeams.com

We are creating an online community of heart surgery teams.
It takes an entire team of healthcare specialists to operate on someone's heart.
The goal of our website:
Heart surgery specialist (surgeons, nurses, anesthetists, etc) will join our site then create teams with their colleagues. Each team will then share medical insights with the other teams.

Our site will give our members the ability to write their own blog, conduct surveys and polls, video chat, share articles.

Also, they will gain points for their activity on the site and be able to trade the points in for monthly prizes.

Healthcare professionals who specialize in heart surgery.
