The cause of Heavy D's death is finally public knowledge.

According to TMZ, the overweight lover died from a pulmonary embolism caused by a deep leg vein thrombosis. A long flight back to Los Angeles, California, from a Michael Jackson memorial concert in Europe just days before Heavy's death may have been the trigger.

Deep leg vein thrombosis is often associated with long plane flights during which a clot can form due to prolonged immobility. A pulmonary embolism is a blockage of one or more arteries in the lungs, most often caused by blood clots which travel from another part of the body. For Hev, the clot formed in his legs.

Officials from the L.A. County Coroner's Office say Heavy also suffered from heart disease, which could have been a contributing factor in his death, reports the entertainment site. The Coroner's Office has classified the death as "natural."

As previously reported on, Heavy D died on November 8, 2011. He was 44 years old and left behind an 11-year-old daughter named Xea.

TMZ also got a hold of the frantic 911 call made the day Heav passed. Listen to the audio here.
