Abstract

Background:
@EN althogh a number of indicies of diastolic function based on transmitral flow have been proposed. no single factor seems to be adequate for separating patients with normal from those with abnormal disastolic function.
Pulsed Doppler echocardiography of pulmonary venous flow (PVF) is another non-invasive method to evaluate left ventricular diastolic performance. The purpose of this study is to evaluate the normal PVF pattern by TEE.
@ES Method:
@EN We performed pulsed-wave Doppler studies of the PVF and of the mitral flow by transesophageal-(TEE) and transthoracic echocardiography (TTE) in 11 healthy young adults.
@ES Results:
@EN In TEE. all subjects showed four phases of the PVF pattern : two antegrade systolic phases (early and late : SE and SL.). one antegrade diastolic phase (D) and one retrograde diastolic phase (A). In TTE. there were three pahses of the PVF
pattern :
two antegrade phases (systolic. diastolic) and one retrograde diastolic phase but we couldn't find out early systolic phase flow. Peak velocity of each phase of PVF was as follows : SF was 48.9±14.1cm/sec. SL was 56.3±16.1cm/sec. D was
52.6±14.9cm/sec. A was 21.6±5.9cm/sec. The itming of SL flow wascorrelated significantly with that of peak aortic flow (r=0.42. p<0.01). while the timing of D flow and that of A flow were correlated significantly with timing of mitral E peak
and
A
peak. respectively (r=0.84. p<0.80. p<0.01).
@ES Conclusion:
@EN In the young normal subject. PVF showed four phases of flow pattern and could be easily obtained by TEE. Furthermore it may be used for evaluation of left ventricular function.
