title: Transoesophageal Doppler pulmonary venous flow pattern and left atrial spontaneous contrast in mitral stenosis.
abstract: The relationship between transoesophageal Doppler pulmonary venous flow pattern and spontaneous left atrial contrast was studied in 23 patients with isolated severe mitral stenosis (mitral valve area = 0.8 +/- 0.2 cm2). The patients with none or minimal (1+) spontaneous contrast (n = 15, group I) were compared with those with significant spontaneous contrast (grade 2+, n = 8, group II) with regard to peak systolic velocity (33 +/- 14 cm/s vs 28 +/- 12 cm/s, p = NS), peak diastolic velocity (36 +/- 14 cm/s vs 28 +/- 8 cm/s, p = NS) and peak atrial reversal velocity (19 +/- 4 cm/s vs 19 +/- 8 cm/s, p = NS), systolic forward flow velocity time integral (3.37 +/- 1.73 cm vs 2.78 +/- 0.9 cm, p = NS), diastolic forward flow velocity time integral (2.85 +/- 1.2 cm vs 2.65 +/- 1.87 cm, p = NS), ratios of peak systolic and diastolic velocity (0.91 +/- 0.21 vs 0.95 +/- 0.29, p = NS) and duration of diastolic deceleration (117 +/- 59 ms vs 132 +/- 106 ms, p = NS). The results show that the occurrence of spontaneous contrast in the left atrium in patients with mitral stenosis is not related to the Doppler-estimated pulmonary venous flow.
