Should not yet alter EF-based assessment in HF; supports further study of atrioventricular plane displacement as dual-performance marker.
Left atrioventricular plane displacement reflects both systolic and diastolic left ventricular performance in patients with chronic heart failure, which may explain discrepancies between this measure and ejection fraction.
Ronnie Willenheimer (1999) studied this question.
