Abstract :Purpose: Prominent Crista Terminalis insert ignore into journalissuearticles values(PCT); is a frequent variation of the right atrium insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(CMR);. Methods: Between 2016 and 2020, 140 patients insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(RV); end-diastolic diameter insert ignore into journalissuearticles values(ED);, RV, left ventriculi insert ignore into journalissuearticles values(LV); ejection fraction insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(r<0,5); between PCT thickness and RVEF insert ignore into journalissuearticles values(r=0.49);, LVEF insert ignore into journalissuearticles values(r=0,115);, RAED insert ignore into journalissuearticles values(r=0.32);, RVED insert ignore into journalissuearticles values(r=0.07);. Fourteen patients insert ignore into journalissuearticles values(10%); with PCT had a history of arrhythmia. Arrhythmia was not observed in patients with PCT less than 10 mm. It was observed that the risk of arrhythmia increased with PCT thickness. Conclusion: CMR image features provided reliable data for patient management in PCT diagnosis and follow-up. There was not detected statically significant change in right and left heart functions in patients with PCT. It was observed that there was a relationship between arrhythmia incidence and PCT dimension in patients.
