A 38 year old woman with diabetes mellitus and bronchial asthma was admitted to hospital with pneumonia caused by Mycoplasma pneumoniae; she recovered promptly on erythromycin treatment. Six weeks later she presented with aortic valve endocarditis without concurrent lung disease. A concurrent increase in titres of antibody to Legionella bozemanii, L longbeachae, and L jordanis indicated a Legionella infection. Legionella infection should be considered, even in the absence of pneumonia, in cases of endocarditis where no other cause can be detected.

To our knowledge, Legionella pericarditis has been reported only four times in the literature and only once without pneumonia. We report the second case of nonpneumonic Legionella pericarditis in a man who eventually required pericardiectomy for constriction. Since Legionella endocarditis, myocarditis, and pericarditis have all been documented by culture or direct fluorescent antibody staining, it is important to be aware of the possibility of cardiac legionellosis.

Surgical patients appear to be at highest risk for acquisition of nosocomial Legionella pneumonia; most appear to become infected during respiratory tract manipulation and mechanical ventilation. Although the lungs are the most common site of nosocomial Legionella infection, an important subset of patients have infection at extrapulmonary sites. We describe 22 cases of extrapulmonary legionellosis reported in the literature. Most of these patients were surgical patients; more than half did not have serious underlying illnesses, and only five (23%) were receiving immunosuppressive agents. A total of 13 extrapulmonary sites of infection were reported, many in the absence of clinical pneumonia; these infections included sinusitis, hip wound infection, and prosthetic valve endocarditis. Five patients (23%) had fatal infections; in four of these cases diagnosis of Legionella infection was made after death, underscoring the need for a high index of clinical suspicion. A large percentage of extrapulmonary Legionella infections may result from direct topical exposure of susceptible tissue to contaminated tap water. Use of tap water must be carefully monitored, particularly in dressing changes and bathing of surgical patients.

Legionnaires' disease is the designation for pneumonia caused by the Legionella species. Among the rare extrapulmonary manifestations, cardiac involvement is most prevalent, in the forms of myocarditis, pericarditis, postcardiotomy syndrome, and prosthetic valve endocarditis. Mechanical circulatory support has proved to be a safe and effective bridge to myocardial recovery in patients with acute fulminant myocarditis; however, to our knowledge, this support has not been used in infectious myocarditis specifically related to Legionellosis. We describe a case of Legionella myocarditis associated with acute left ventricular dysfunction and repolarization abnormalities in a 48-year-old man. The patient fully recovered after left ventricular unloading with use of a TandemHeart percutaneous ventricular assist device. In addition, we review the English-language medical literature on Legionella myocarditis and focus on cardiac outcomes.

Legionella pneumophila infection (legionellosis) usually presents as a multisystemic disease, predominantly affecting the lungs (Legionnaires' disease - LD). Immunodeficiency, chemotherapy or chronic steroids use increase the risk of developing LD. Extrapulmonary manifestations of LD include cardiac complications: myocarditis, pericarditis or endocarditis.
