In the tetralogy of Fallot group, left ventricular ejection fraction was negatively related to the right ventricular end-systolic volume normalised to body surface area (r=\u22120.62, p&lt;0.01). An association was found in patients between the right atrial peak longitudinal strain and mean right ventricular strain (r=0.64, p&lt;0.01). In patients, the left atrial peak longitudinal strain correlated negatively with right atrial end-diastolic volume normalised to body surface area (r=\u22120.67, p&lt;0.01), whereas the left atrial ejection fraction correlated weakly with left ventricular ejection fraction (r=0.41, p&lt;0.05).\n                    <jats:italic>Conclusions:<\/jats:italic>\n                    In asymptomatic tetralogy of Fallot patients, biatrial dysfunction exists and can be quantified via two-dimensional speckle tracking echocardiography as well as real-time three-dimensional echocardiography. Different forms of interactions on atrial and ventricular levels are evident among such cohorts.\n                  <\/jats:p>","DOI":"10.1017\/s1047951114002108","type":"journal-article","created":{"date-parts":[[2014,10,23]],"date-time":"2014-10-23T11:33:39Z","timestamp":1414064019000},"page":"1254-1262","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":21,"title":["Assessment of inter-atrial, inter-ventricular, and atrio-ventricular interactions in tetralogy of Fallot patients after surgical correction.
