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.
