CONCLUSION:
Use of transmitral flow velocity, deceleration times and pulmonary vein
Doppler velocities reveal poor predictive capacity for detecting high
left sided filling pressures (PCWP ≥15 mm Hg). The use of E/Ea is
reasonable to predict an elevated PCWP especially if the cohort
predominantly comprises of patients with normal ejection fraction and
where in an overwhelming majority are undergoing myocardial
revascularisation without cardiopulmonary bypass. Also, the study, with
the caveat that limited patient numbers have been enrolled suggest
different cutoff points for this estimate than previously reported.
