Case of a Middle-Aged Woman with Sick Sinus Syndrome and Cor Triatriatum Dexter.

This case study involves a 51-year-old woman with a complex cardiovascular condition, namely cor triatriatum dexter, accompanied by sick sinus syndrome. She presented with bradycardia, dizziness, and amaurosis, and was admitted to the emergency department due to right limb numbness. Diagnostic examinations, including computed tomography and cardiac color ultrasound screening, revealed the presence of cor triatriatum dexter with an enlarged left atrium and ventricle. Additional abnormalities, such as absent inferior vena cava and polysplenia syndrome, were also detected. Based on the findings, a double-chamber pacemaker surgery was recommended, supported by cardiac and thoracic-abdominal computed tomography angiography and three-dimensional vascular reconstruction.
