Fig. 2From: Assessment of left atrioventricular coupling and left atrial function impairment in diabetes with and without hypertension using CMR feature tracking A schematic representation of the left atrial volume and left atrioventricular coupling index (LACI). The left atrial area for the 2-chamber (a1) and 4-chamber (a2) views. The left atrial volume was calculated using the biplane formula mentioned above. The left atrial volume and left ventricular volume at end-diastole are represented in (b). The LACI was obtained by calculating the ratio of end-diastolic left atrial volume to left ventricular volumeBack to article page
