    Abstract:
    The authors report the results of a multicenter study which recensed 59 cases (46 men, 13 women, average age 59.8 +/- 14 years) of valve ring abscesses defined by echocardiographic criteria alone (20 cases) or by echocardiographic and/or operative criteria (39 cases). The site of abscess was aortic (53 cases), mitral (5 cases) and tricuspid (1 case). The abscess complicated a prosthetic valve in 34 cases, occurred with a non-pathological valve in 11 cases or a pathological valve in 14 cases. Taking the 39 operated patients as a reference, the diagnostic sensitivity of transthoracic echocardiography was 25% and that of transoesophageal echocardiography: 88%. Bacterial vegetations were diagnosed with a sensitivity of 55% for transthoracic and 88% for transoesophageal echocardiography. The mediocre results of transthoracic echocardiography make transoesophageal echocardiography mandatory when there is a clinical suspicion of abscess: transoesophageal echocardiography should be systematic in prosthetic valve endocarditis and widely employed in native aortic valve endocarditis. The clinical outcome of these cases was: 39 cases were operated: global mortality of 23%, and 18 cases were treated medically, surgery having been declined for various reasons: old age (2 patients), operative risk (1 patient), patient refusal (4 patients), general condition considered to be too good to justify surgery (11 cases, including 6 sterilised abscesses diagnosed some time after the acute infectious phase). The outcome of these 18 patients, who form the biggest non-operated series of valve ring abscesses to date, was studied in detail: 4 died (18% mortality), 1 was operated secondarily for progressive valve dehiscence and 13 had a favourable outcome with an average follow-up period of 2 years.(ABSTRACT TRUNCATED AT 250 WORDS)
