Early transesophageal echocardiography (TEE) after mitral valve replacement can detect symptomless, non-obstructive thrombus on prosthetic valves and also small filamentous abnormal echoes (SAE). The object of this study is to evaluate their respective frequency and predisposing factors. Between October 1988 and June 1992, 129 consecutive patients underwent mitral valve replacement with a bileaflet prosthesis and had transesophageal echocardiography at an average of 15 +/- 7 days (range: 6-35 days) after surgery. Details of postoperative anticoagulation were analyzed in 99 patients from five surgical centers having comparable postoperative anticoagulation protocols. Among those patients presenting with SAE, 76% had a second transesophageal echocardiography at an average of 145 +/- 166 days after the first examination. Mean age was 56 +/- 13 years. Small filamentous echoes were found in 55 patients (43%). In univariate analysis, independent predictors were age, absence of systolic regurgitation across the mitral prosthesis as observed with continuous Doppler, and the presence of spontaneous echo contrast (SC) in the left atrium: 54 +/- 14 years in the absence vs. 59 +/- 10 in the presence of SAE (p < 0.05); 54% of systolic leak vs. 36% (p < 0.05); 43% of SC vs. 75% (p < 0.00001). In multivariate analysis, spontaneous echo contrast was the only independent predictor for SAE (p < 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)
