ABSTRACT

This case follows a 25 year old female patient, initially diagnosed with a congenital auricular-ventricular blockage that required a definitive bicameral pacemaker. The auricular electrode had to be changed on various occasions due to malfunction and on one of these occasions, the complete system was changed (1998). The patient was admitted on 9 June 2000 suffering from febrile syndrome, attributed to typhoid fever and/or urinary tract infection, that persisted until the start of treatment. In the hospital, a fever of 38°C was recorded with general malaise and slightly altered febrile reactions; renal ultrasound showed right sided pyelonephritis, leucocytes were at 16,000 and a blood culture positive to Gram positive although the specific germ was not identified. The presence of various foreign bodies in the right cavities of the heart permited to suspect the diagnosis of infectious endocarditis of the right cavities, which was confirmed by an echocardiogram. Given the evidence of blood clots in the right cardiac cavities, in addition to the sudden and final clinical picture, it is logical to think that the patient had a pulmonary thromboembolism with cardiac failure, severe sepsis and consequently shock: obstructive and septic.
