Background:One of the most important reasons for nasal congestion is septum deviation. Nasal septal deviation increases airway resistance and can cause systemic problems. In this study, echocardiographic findings were compared with the normal population to see how cardiac function was affected in patients with obstructive nasal septum deviation.Methods:This study included a young patient group with 44 obstructive septum deviation patients and 30 healthy individuals with no nasal-related problems. Echocardiography was performed by the same cardiologist and results were compared with normal patients. The authors got permission from the ethics committee of faculty for the study (E. 116795).Results:In the patient group with septum deviation, pulmonary artery pressure was high. In addition, the size of the right heart chambers was also increased. TAPSE, pulmonary acceleration time, ejection fraction, and right ventricular outflow tract-fractional shortening were found to be lower than the normal group.Conclusion:Patients with obstructive septum deviations should be evaluated early for cardiologic functions.
