Mitral annular plane systolic excursion (MAPSE) reflects longitudinal left ventricular function, predicts survival in heart failure patients and provides a sensitive marker of early systolic dysfunction in hypertensive patients with normal ejection fraction (EF). Doppler mitral annulus velocity (e') in early diastole predicts cardiac mortality, differentiates diseases and estimates filling pressures. We present a practical technique that facilitates measuring atrioventricular junction (AVJ) motion throughout the cardiac cycle from cine cardiac magnetic resonance (CMR) and correlate these measurements with EF and echocardiography-determined e'.
Seventeen woman and 10 men with a mean age of 59 (range 36-82) underwent CMR and TTE. Mean values for CMR-derived EF and TDE e' were found to be 53% (range 28-71% and 11 cm/s (range 3-18 cm/s), respectively. Moderate correlations were found between MVED and e' (r = 0.624, p = 0.001) as well as EF and MD (r = 0.486, p = 0.01). A moderate correlation was also found for MD and left ventricular stroke volume (r = 0.504, p = 0.007). Atrioventricular junction analysis was performed offline and took approximately 10 minutes per patient.
Atrioventricular junction analysis is a practical CMR technique that yields CMR measurements of diastolic and systolic function. A moderately strong correlation was found between CMR-derived MVED and e', as well as EF and MD.
