The echocardiograms and clinical records of 70 patients with infective endocarditis seen between 1983 and 1988 were examined to evaluate the role of two-dimensional and Doppler echocardiography in the diagnosis of infective endocarditis and identify risk factors for morbidity and mortality. A blinded observer reviewed the echocardiograms for the presence and size of vegetations and the severity of the valvular regurgitation. Vegetations were identified in 54 (78%) of 69 technically satisfactory echocardiograms. In 38 patients whose heart was examined at surgery or autopsy, all vegetations diagnosed by echocardiography were confirmed, but six additional vegetations were found. Abnormal (greater than or equal to 2+) valvular regurgitation was present in 88% of patients. No patient with less than or equal to 1+ regurgitation (n = 8) died or required valve surgery for heart failure, but three of the eight patients did undergo surgery for mycotic aneurysm, recurrent embolism or paravalvular abscess. In patients without embolism before echocardiography, there was a trend toward a greater incidence of subsequent embolism in those with vegetations greater than 10 mm in size (26% [8 of 31] compared with 11% [2 of 18] with vegetations less than or equal to 10 mm) (p = 0.19). By multivariate analysis, risk factors for in-hospital death (n = 7) were an infected prosthetic valve (p less than 0.007), systemic embolism (p less than 0.02) and infection with Staphylococcus aureus (p = 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

A case of bacteremia due to Campylobacter fetus subspecies fetus with concomitant pleuropericarditis in a previously healthy patient is presented. The organism is ubiquitous, but most commonly causes infection in patients with chronic underlying illnesses. The pathogenesis of human infection has not been definitively elucidated. Bacteremia is the most common clinical manifestation of this infection, although cases of thrombophlebitis, mycotic aneurysm, endocarditis, and pericarditis have also been reported. The treatment of choice for most infections is gentamicin, with chloramphenicol recommended for infection involving the central nervous system. Tetracyclines and erythromycin are alternative agents. Prolonged therapy is essential to the prevention of relapse. A high index of suspicion is necessary for the recognition of this organism in the appropriate clinical settings.

A case in which rupture of a hepatic artery aneurysm occurred 4 months after aortic valve replacement because of aortic regurgitation due to infective endocarditis (IE) is reported. The patient was a 41-year-old male who underwent aortic valve replacement and closure of an abscess cavity of the Valsalva's sinus because of aortic regurgitation and an abscess of the Valsalva's sinus complicated with active IE. His postoperative course was good with no fever. Four months postoperatively, rupture of an aneurysm of the left intrahepatic artery occurred suddenly, and the patient's life was saved by resection of the lateral segment of the left lobe of the liver. Histologically, the wall structure of the aneurysm was not preserved, infiltration of neutrophils was seen in part of the wall, and a mycotic aneurysm of the left hepatic artery within the liver cause by IE was diagnosed. In Japan, only four cases, including the present one, of mycotic aneurysm of the hepatic artery have been reported in the literature examined, and this was the first case in which the patient's life as saved after a rupture. It is essential when observing the course of IE patients to bear in mind at all times that such a complication might occur.

We report a case of mycotic aneurysm of the femoral artery which highlights the diagnostic features and management problems of the condition. Our patient required emergency ligation of the artery for life-threatening haemorrhage and subsequently his leg was not viable. The alternative treatment options of simple ligation and excision versus ligation, excision and immediate bypass grafting of the artery are discussed. The causative organism, beta-haemolytic group B streptococcus (S. Agalactiae), is an extremely rare cause of embolic mycotic aneurysm. This rarity is unexplained and is surprising since this organism is a well-known cause of infective endocarditis, which can be complicated by mycotic aneurysms. Mycotic aneurysms may become more common because of the rise of intravascular drug abuse, which combines the risk factors of vessel trauma, endocarditis and immunosuppression, notably from HIV infection.

Among 143 episodes of endocarditis experienced in children over a 38-year period from 1950 to 1988, 23 patients required surgical intervention, including 11 valve replacements, 2 valve repairs, 7 mycotic aneurysm resections (most related to coarctation or ductus), and 3 instances of debridement and repair of the ventricular septum. Left-sided vegetations associated with endocarditis have traditionally been managed surgically only if repeated emboli have occurred. Following the unfavorable outcome in several patients with large mobile vegetations on the mitral valve, we have adopted a more aggressive surgical approach to debride and repair left-sided valves involved with such vegetations.

Significant streptococcal (non-pneumococcal, non-enterococcal) bacteraemia was detected in 100 patients in two Health Districts of North Yorkshire in the decade 1978-1988. Patients with these infections accounted for 11% of the total 902 patients in the districts in whom bacteraemia was diagnosed during the period. Infection was most often seen with beta-haemolytic streptococci (52 patients) comprising Lancefield group A (Streptococcus pyogenes) (20 patients), group B (13), group C (5), group G (9), haemolytic Streptococcus milleri and non-groupable streptococci (5). The wide variety of serious infections included cellulitis, abscess, septicaemia, pneumonia, septic arthritis, necrotising fasciitis, acute endocarditis and mycotic aneurysm. Of these 52 patients, 21 (40%) died. alpha-Haemolytic streptococcal bacteraemia was diagnosed in 38 patients of whom 24 (63%) suffered from endocarditis and three (8%) died. Three of ten patients with non-haemolytic or anaerobic streptococcal bacteraemia died also. Six of the 100 patients with streptococcal bacteraemia had concomitant acute virus infections. Of the total 56 patients with infective endocarditis diagnosed in the districts during the period, streptococci were responsible in 30 (54%) of them. The predisposing factors, clinical features and outcome of the infections are described and discussed.

The medical records of 97 consecutive patients (101 episodes) of infective endocarditis seen from January 1979 through January 1987 were reviewed. Only 30% of the patients were over 50 years of age and the majority (69%) of infecting organisms were streptococci (mainly of the viridans group), which were similar to those reported from the West in the early antibiotic era. Pseudomonas organisms and enterococci accounted for 6% and 5%, respectively. Fungal infections were noted in 2 patients. There was a high incidence (38%) of predisposing rheumatic valvular disease; approximately half of these patients had prosthetic valve infections. Mitral valve prolapse was also an important predisposing disease (11%). One-third (34%) of the patients had febrile illness for longer than 8 weeks before the diagnosis was established. The hospital morality rate was 22%; cerebral embolism and ruptured mycotic aneurysm, congestive heart failure, and sudden death were the major causes of death. Echocardiography disclosed vegetations on the cardiac valves and preexisting lesions in 75% of the episodes. Early recognition and proper treatment should be the focus of efforts to reduce mortality from infective endocarditis.

A 49 year-old woman was hospitalized with headache and left-sided weakness. Computed tomographic scan and carotid angiogram revealed mycotic aneurysms of the bilateral middle cerebral artery with intracranial bleeding. Although all blood cultures were sterile, her physical examination suspected mitral regurgitation due to infective endocarditis and mycotic cerebral aneurysms. Severe congestive heart failure developed immediately after successful clipping for ruptured mycotic aneurysm of the right middle cerebral artery and then mitral valve replacement with prosthetic valve was performed 3 months after craniotomy. At operation, infective endocarditis on the mitral valve was confirmed. Her postoperative course was uneventful and the second craniotomy for aneurysm of the left middle cerebral artery has been planning.

Massive hemoptysis is a rare complication of bacterial endocarditis. When seen, it is most often due to septic pulmonary emboli with infarction or rupture of a mycotic aneurysm of the pulmonary artery; these conditions are usually associated with endocarditis of the tricuspid valve. We report a case of fatal hemorrhage into the lung from a mycotic aneurysm of the subclavian artery, which eroded into the left upper lobe; this condition arose as a sequela of staphylococcal endocarditis involving the mitral valve.
