Cor triatriatum is a rare congenital anomaly with an incidence of 0.1%–0.4%. It is characterized by failure of resorption of the common pulmonary vein and results in division of the left atrium by an abnormal fibromuscular membrane into a posterosuperior chamber receiving pulmonary veins and an anteroinferior chamber leading to the mitral orifice.
Most of the patients with cor triatriatum present in infancy, mimicking congenital pulmonary vein stenosis or mitral stenosis. Its appearance in the elderly is very rare or even more exceptional.,,,
A 68-year-old gentleman was referred to our cardiology department for early surgical excision of cor triatriatum. He was a chronic smoker, and had symptoms of progressive dysphagia and weight loss for 3 months. He had been evaluated in other tertiary care hospital, and had been advised for early surgical excision of cor triatriatum. At the time of presentation, the patient was gasping, altered sensorium, hypotensive with blood pressure of 80/50 mmHg. His pulse rate was 110 per minute, and respiratory rate was 30 per minute. Cardiovascular examination revealed normal S1 and S2 and no murmur; chest auscultation revealed gurgling breath sounds. Echocardiography showed the membrane in the left atrium with maximum gradient of 6 mmHg [Figure 1], [Figure 2] and [Video 1],[Video 2],[Video 3], mild enlargement of left atrium, mild eccentric mitral regurgitation, mild tricuspid regurgitation, and mild pulmonary artery hypertension (Right ventricular systolic pressure = Right atrial pressure + 28 mmHg). Low gradient across the membrane favored asymptomatic presentation of cor triatriatum in this index case. The patient was admitted in the emergency and arterial blood gas showed pH of 7.1 with increased lactate levels and total leukocyte count of 24,000/μl. He was managed on lines of sepsis with septic shock; however, he succumbed after 6 h of admission.

This case highlights the atypical presentation of cor triatriatum sinister in an elderly man. An echocardiography serves as a very useful tool in prompt diagnosis and management of cor triatriatum. This index patient died due to some other cause rather than cor triatriatum sinister.
