The relationship between left atrial diameter (LAD), a robust predictor for thrombosis, and LVNC is unclear. The purpose of this study was to explore the effect of LAD on the thrombotic risk in LVNC.<h4>Methods</h4>In this retrospective cohort study, 320 patients with imaging characteristics of LVNC were included for statistical analysis. The primary endpoint was a composite event of intracardiac thrombi and stroke or transient ischemic attack (TIA). The secondary endpoints were intracardiac thrombi and stroke/TIA.<h4>Results</h4>The 320 included patients (211 [65.9%] men, median age: 45 years [interquartile range: 30-57]) were divided into LAD1 (&lt;43 mm, <i>n</i> = 157) and LAD2 (≥43 mm, <i>Journal of cardiovascular development and diseaseLeft Atrial Diameter and the Risk of Thromboembolism in Patients with Left Ventricular Noncompaction.PMC97885992022-GSP-GG-26Z1911000066191212018-2-4031Yang YZhu JTan JXu WWang JWang LfalseLeft Atrial Diameter and the Risk of Thromboembolism in Patients with Left Ventricular Noncompaction.<h4>Aims</h4>Patients with left ventricular noncompaction (LVNC) are at risk of thromboembolism.
