The periprosthetic abscess due to infective endocarditis constitutes a severe complication of an aortic valve replacement, causing high mortality, despite combined medical and surgical treatment, especially in "early" endocarditis. Transthoracic echocardiography, and especially transesophageal study, is the election procedure for a non invasive diagnosis of vegetation and local complications. We report the aggressive and fulminant case of a 43 year old woman with aortic periprosthetic abscess and the extension to both auricles, due to Staphylococcus epidermidis.

INTRODUCTION AND OBJECTIVES: The study was performed to test the influence of the jet spatial disposition on the correlation degree between the measurement of the jet width at its origin and the severity of mitral prosthetic regurgitation by transesophageal Doppler color flow imaging. MATERIAL AND METHODS: In 165 patients with mitral valve prosthesis which were submitted for transesophageal echocardiography examination due to suspected prosthetic dysfunction, we studied 126 with pathological mitral regurgitation. On these patients, studies of jet spatial disposition, maximum width in its origin and severity quantification by means of maximum regurgitation area were performed. RESULTS: For the free jet group of patients (90), jet width at its origin correlated with maximal regurgitation area (r = 0.75); whereas for the wall jet group (36), the correlation degree was 0.59. We observed a relationship (p < 0.05) between severe mitral regurgitation assessed by maximal regurgitant jet size and jet width > or = 5 mm in both groups: the sensitivity and specificity of 72.7% and 95% respectively for free jets, and 70.7% and 64.4% for wall jets. CONCLUSIONS: The correlation between the area measurement and the width in its origin is better for free jets than for wall jets. A statistically significant relationship between the presence of severe mitral regurgitation and width in its origin > or = 5 mm could be observed, independently of the jet spatial disposition.
