The former ER star, who played Nurse Malik McGrath of the hit medical drama, had his aorta replaced and a leaking heart valve fixed in a gruelling six-hour operation last week (14Jul09).
The actor - real name Dearon Thompson - has now been released to continue recuperating at home and he is thankful to his former TV co-stars and fans for lending their support in his time of need.
He tells RadarOnline.com, "Most of the cast from ER supported me - Eriq La Salle, Noah Wiley were at my bedside before and after my surgery. Shi McBride came and stayed with me and supported me.
And Thompson admits his health scare has strengthened his belief in a higher power.
He adds: "Thanks for all the prayers and love, the entire experience made God more tangible in my life. I just can't explain in words what I felt.".
