Single-plane LV echo discrepancies post-MI warrant caution; hypothesis-generating and should not yet change practice.
Does single plane two-dimensional echocardiography correlate with biplane Simpson's method for calculating left ventricular volumes and ejection fraction in post-infarction patients?
Single-plane echocardiography overestimates left ventricular volumes and underestimates ejection fraction compared to the biplane Simpson's method, especially in dilated and distorted hearts.
Martin St. John Sutton (1998) studied this question.
