Los Angeles dancer, Gaviari Gilliam, a top dancer who appeared on shows like Jimmy Kimmel and Tyler Perry productions, collapsed during rehearsals and was rushed to Cedars-Sinai Medical Center after suffering a cardiac arrest. Doctors discovered that he has a rare heart condition called hypertrophic cardiomyopathy, which causes thickening of the walls of the heart, making it harder for the heart to pump blood. Until a donor heart becomes available, Gilliam will need an artificial heart to sustain him, which will involve multiple procedures, extended hospital care, and a costly transplant and recovery process. Gilliam's family has described the situation as "very serious" and hopeful that he will soon return to dancing.
