Cor triatriatum sinister is a rare congenital cardiac anomaly in which a fibromuscular membrane divides the left atrium into 2 chambers. It is even rarer when present at an adult age. Symptoms and presentation of the patient depend on the size of the opening in the membrane through which 2 chambers of left atrium communicate with each other. Cor triatriatum sinister rarely remains asymptomatic till adulthood. In adults, symptoms of Cor triatriatum sinister mimic the symptoms of mitral stenosis. Corrective surgery is the treatment of choice, but when it presents as an emergency case especially at an early age, balloon dilatation of the membrane opening can be done. Elective balloon dilatation of membrane opening at an early age diagnosed with Cor triatriatum sinister followed by corrective surgery at an adult age can be a safer option compared to direct corrective surgery at an early age. We present a case of a 25-year-old female.
