Prominent Crista Terminalis Magnetic Resonance Imaging Findings

Abstract

Purpose: Prominent Crista Terminalis (PCT) is a frequent variation of the right atrium (RA) posterior wall with a pseudotumor image. The aim of this study is to evaluate PCT image characteristics and cardiac functional effects with cardiac magnetic resonance imaging (CMR). Methods: Between 2016 and 2020, 140 patients (58 ±14 years) were evaluated retrospectively. PCT was measured in 2 planes with the longest thickness at the atrial end-diastole. Patients with crista terminalis thickness greater than 8 mm were evaluated. Patients were assessed by the RA, right ventricular (RV) end-diastolic diameter (ED), RV, left ventriculi (LV) ejection fraction (EF), and PCT diameter were included in the study. After the Kolmogorov-Smirnov normality test, cases were compared with the paired student t-test. Mann-Whitney test was used for comparison of non-parametric variables. The effect of the increase in PCT diameter on the RVEF, LVEF, and RAED, RVED was investigated using Pearson's correlation coefficient. Results: There was no significant correlation (r
