An Unusual Thrombosis Mimicking Cor Triatriatum Dextra

diagnosed Bartter syndrome. In her history, it was learned that she was hospitalized for sepsis, pneumonia and was cannulated with the umbilical venous catheter. Seventh day of the birth, echocardiography performed due to murmur had no additional pathology other than foramen ovale. In her physical examination, the heart rate was 136/bpm, respiratory rate was 28/ min, blood pressure was 85/52 mmHg, and peripheral oxygen saturation was 94% by pulse oximetry. The patient had no dyspnea. There was a 2/6 systolic murmur over mesocardiac area. Complete blood count revealed leucocyte: 14.000/mm 3 , hemoglobin: 11 g/dl, platelet: 280000/mm 3 . Hepatic and renal function tests, C reactive Abstract Central venous catheters are commonly used in clinical practice. Right atrial thrombosis is a relatively common complication associated with indwelling catheter use. Thrombosis can be in different locations and forms within vascular and intracardiac structures. Echocardiographic images may mimic some anatomic and pathologic variants. We describe a case of a two-months-old girl with a thrombus which cor triatriatum dexter-like appearance in the right atrium due to the central venous catheter.
