Fig. 3From: An acute increase in Left Atrial volume and left ventricular filling pressure during Adenosine administered myocardial hyperaemia: CMR First-Pass Perfusion StudyBox plots illustrating the comparison between different CMR parameters at baseline and stress and their significance in all patient cohorts. Predominantly, the left atrial end-ventricular systolic volume increased the most and directly impacted the left ventricular filling pressure, which also correspondingly increased. The left atrial ejection fraction also significantly increased. The increase in right atrial volume was less significantBack to article page
