Cardiac complications of Wegener granulomatosis: a case report of complete heart block and review of the literature.

Wegener granulomatosis is a necrotizing vasculitis whose target organs are classically the upper and lower respiratory tracts and the kidneys. There has been other end-organ involvement documentation, emphasizing the disseminated nature of this disease, but the literature concerning cardiac involvement is limited. The few case reports and general reviews show that the two most common histologic cardiac manifestations are pericarditis and coronary arteritis, each occurring in 50% of the reported cases. The most frequent clinical manifestation is cardiac arrhythmias that are manifested as supraventricular tachyarrhythmias. We report an unusual cardiac manifestation, a case of complete heart block, occurring during the active stage of Wegener granulomatosis. The problem this case presented and the management are reported. The literature dealing with the cardiac involvement in Wegener granulomatosis is reviewed, and the specific histopathologic findings and the pathophysiologic mechanisms of this involvement are discussed.

Infective endocarditis as a complication of heroin use.

Infective endocarditis in heroin addicts has been reported to have a mortality as high as 85% and reports have varied widely regarding predominant valvular involvement and infecting microorganisms. A retrspective study was done and 61 cases of heroin-associated infective endocarditis were identified at Freedmen's Hospital and the District of Columbia General Hospital, Washington, DC between January 1969 and January 1973. Our results indicate that staphylococcal infection of the tricuspid valve has a much higher incidence in this population than has generally been believed and that it is the predominant presentation of infective endocarditis in these patients. The outcome of patients in our series compares favorably with previous reports and suggests that early diagnosis and prompt institution of appropriate antimicrobial therapy are important and may lead to improved survival in addicts with tricuspid endocarditis.
