Immediate tricuspid valve replacement for endocarditis. Indications and results.

Tricuspid valve excision for tricuspid endocarditis in addicts is recommended to avoid early reinfection, continued sepsis, and late reinfection because of the resumption of intravenous drug abuse. Valvectomy is allegedly well tolerated hemodynamically by some, but it leads to heart failure in at least a third of patients. In our experience in 10 addicts with staphylococcal endocarditis who had failed to respond to antibiotic therapy, tricuspid valve replacement allowed all 10 to leave the hospital free of infection and free of heart failure. Resumption of drug addiction in three led to septic death, but not necessarily to tricuspid reinfection. Two returned to jobs requiring a high level of physical labor and tolerated this without difficulty. We find no need to follow the practice of tricuspid valve excision for tricuspid endocarditis in addicts. Those who refrain from drug abuse are well served by valve replacement. Those who do not are doomed with or without a tricuspid valve.
