Core tip: It is presumed that tricuspid valve endocarditis is uncommon in the Middle East region. However, recently published global data indicate growing trends in the use of illicit drug abuse in the Middle East Gulf region. The Middle East Gulf States, currently a transit market, are also becoming a growing consumer market in view of the consumption patterns of substance abuse in the youth.
