Abstract

Right ventricular systolic pressure (RVSP) estimation by tricuspid regurgitation method is not always feasible. We hypothesized that TAM is influenced by RSVP and therefore can detect PHT. Doppler echocardiography and DTI of the lateral (L) and medial (M) TAM from 4 chamber apical view were performed in 83 normal subjects age 49±17 and 35 pts age 64±15 with PHT (RSVP=62±11 mm Hg), all in sinus rhythm. TAM exhibits a systolic wave(s) and 2 diastolic waves e' and a'. Peak velocity (PkV) and time velocity integral (TVI) of TAM waves were averaged from 3 cardiac cycles. Logistic regression analysis after controlling the effects of age, LVEF and gender was used. A p-value <.05 was considered significant. The variables significantly associated with PHT are: Variable Est.Parameter SE p-value Odds Ratio PVA .072 .033 .027 1.08 RVDD 1.180 .570 .039 3.25 TVIe'L 1.10 .517 .031 .328 TVIsM -2.95 .09 .003 .052 PkVsM -.35 .172 .030 .700 TVIe'M -4.60 1.36 .001 .010 PkVe'M -.41 .15 .008 .665 Est. = Estimated; SE = standard error; PVA = pulmonic veins PkV awave; RVDD=right ventricular diastolic diameter. Conclusions: 1. The parameters described have a significant association with PHT, TVIe'M being the best discriminator.
