Cor triatriatum is a rare congenital anomaly, and it is diagnosed in 0.4% and 0.1% in autopsy series and clinically respectively. It is frequently accompanied by secundum type atrial septal defect and pulmonary venous return anomaly. We report a case of a 67-year-old female patient admitted to hospital with complaints of palpitation which occurs approximately 3-4 times in a month. Wolf Parkinson White (WPW) syndrome was detected in the electrocardiogram (ECG) and transthoracic echocardiogram showed features of cor triatriatum sinister (CTS), mild mitral regurgitation and left atrial dilatation. She was asymptomatic from CTS pathology. Although there was no documented tachycardia, because of intermittent palpitation, preexitation features in the ECG, left atrial dilatation and a potential for dangerous atrial fibrillation, we performed electrophysiological study. The accessory pathway was detected in the posterior mitral annulus and ablated successfully. Since she was asymptomatic, surgical treatment for CTS was not recommended. Although the concomitant CTS with other congenital heart diseases has been reported, to the best of our knowledge, there is only one previous case report in the literature regarding association of CTS with WPW syndrome.
