An autopsy later confirmed that Laniado died from cardiac hypertrophy, a condition involving an enlarged heart.

A search of his hotel room revealed he had been taking multiple substances banned in France, along with vasodilators commonly used to treat erectile dysfunction. According to judicial sources, these substances are believed to have contributed to his death.

Ah, so it had nothing to do with the procedure, dude was on a cocktail of his own drugs, didn't tell the doctor, had a heart attack.

So, if it was anyones fault, it was the pathetic billionaires fault. Also anyone who gets rich from diamonds is always, 100%, a scumbag.
