Echocardiographic findings in patients with temporal arteritis: apropos of one case of temporal arteritis-associated verrucous (Libman-Sachs) endocarditis.

We report the case of a 70-year-old patient who presented with fever of unknown origin. The initial diagnosis was infective endocarditis as a mitral valve vegetation was found in a transesophageal echocardiogram. Lack of response to empiric antibiotic treatment and further diagnostic work-up established the correct diagnosis of marantic endocarditis due to temporal arteritis. Treatment with steroids and aspirin led to rapid clinical improvement and disappearance of the vegetation. Apropos of this case, we reviewed the records of 25 patients with a new diagnosis of temporal arteritis and analyzed the echocardiographic findings in comparison to those of 40 age- and sex-matched controls. Abnormal echocardiographic findings were present in 13 (52%) out of 25 patients with temporal arteritis and in 5 (12.5 %) out of 40 controls (p < 0.001, chi-square test).
