ABSTRACT
OBJECTIVES:
We aimed to investigate whether coronary sinus (CS) dilatation develops in patients with mitral stenosis (MS) and to demonstrate its relationship with the global myocardial performance of the right ventricle (RV).METHODS:
We enrolled 34 patients with MS who underwent echocardiography after exhibiting typical symptoms (31 female; mean age 41 ± 12 years) and 20 age- and sex-matched controls without MS who underwent echocardiography (16 female; mean age 38 ± 13 years). The RV myocardial performance index (MPI) was detected using tissue Doppler echocardiography (TDE), and maximum CS diameter was measured from the posterior atrioventricular groove in the apical four-chamber view during the ventricular systole.RESULTS:
The RV MPI was significantly higher in the MS group compared to the control group (0.60 ± 0.11 vs. 0.41 ± 0.08, P < 0.001). Moreover, the maximum CS dimension was higher in the MS group compared to the control group (8.5 ± 1.1 mm vs. 6.5 ± 1.4 mm, P < 0.001). The maximum CS dilatation was positively correlated with the RV MPI (r = 0.691; P < 0.001).CONCLUSION:
The RV MPI, which represents both systolic and diastolic functions, is increased in patients with MS and correlates with CS dilatation.Palavras-chave
