Table 2 Paired t-test analysis of ASD diameter and rim sizes between TEE and CMR

From: Phase contrast cardiac magnetic resonance imaging versus transoesophageal echocardiography for the evaluation of feasibility for transcatheter closure of atrial septal defects

Parameter TEE (mean ± SD) CMR (mean ± SD) Mean difference (95% CI) p value
ASD diameter (mm) 24.16 ± 9.09 25.77 ± 7.47 − 1.6 (− 2.8, − 0.4) 0.013
AS rim (mm) 5.34 ± 2.61 5.82 ± 3.02 − 0.5 (− 1.1, 0.1) 0.112
PS rim (mm) 11.81 ± 5.87 12.59 ± 5.52 − 0.8 (− 2.0, 0.5) 0.225
AI rim (mm) 11.58 ± 5.33 12.97 ± 6.09 − 1.4 (− 2.8, 0.1) 0.060
PI rim (mm) 10.81 ± 6.80 12.79 ± 6.93 − 2.0 (− 3.7, − 0.3) 0.023
