Cor Triatriatum occurs when either the right or left atrium has a flap or tissue or membrane that divides it into two chambers. The classical «Cor Triatrium sinister» is shown in this example where a membrane divides the left atrium into two parts, one receiving the pulmonary venous inflow and the other containing the left atrial appendage and contacting the mitral valve.

🎥1️⃣: On first glance this parasternal long axis appears normal.

🎥2️⃣: A color window however shows that there is abnormal inflow within the left atrium. There also is some turbulence that appears to be in and around the mitral valve as the probe goes in and out of plane.

🎥3️⃣: The apical 4 chamber shows an abnormality in the left atrium that in this study is hard to distinguish at first from artifact.

🎥4️⃣: A close up view shows that this is indeed a membrane.

🎥5️⃣: It is also seen in the 2 chamber view making artifact much less likely to be the cause.

🎥6️⃣: There is also associated turbulence on color Doppler with the membrane which either is not complete or is fenestrated and affects mitral valve inflow.

🎥7️⃣: The subcostal also confirms the finding.
