다국어 초록 (Multilingual Abstract)

The comparison between the results of right ventricular systolic pressure and mean pulmonary artery pressure using catheterization and that of right ventricular systolic pressure and right ventricular systolic time intervals using Doppler echocardiography in patients with tricuspid regurgitation as follows: 1) Adding the tranatricuspid gradient (△P) to the JVP gave prediction of right ventricular systolic pressure (RVSP) that correlated well with catheterization values. 2) There was also significant correlation between the transtricuspid gradient predicted by Doppler echocardiography and RVSP by catheterization. 3) As the mean pulmonary artery pressure (MPAP) increased, the PEP/AT also increased, while AT/ET decreased. When MPAP was less than 20 mmHg, PEP/AT, AT/ET were 1.06±0.12, 0.40±0.05 respectively, while when MPAP was between 20 and 39 mmHg, PEP/AT, AT/ET were 1.37±0.25, 0.33±0.05, and when MPAP was over 40 mmHg, PEP/AT, AT/ET were 1.65±0.21, 0.26±0.03. 4) There was significant correlation hetween the results of PEP/AT obtained by Doppler echocardiography and MPAP obtained by catheterization and negative correlation between the results of AT/ET by Doppler echocardiography and MPAP by catheterization.
