Cor triatriatum pathophysiology


 * If there is an associated PFO or ASD then this may decompress the pressure in the pulmonary veins by diverting blood into the right atrium.
 * If the ASD is located superior to the diaphragm, there will be a large shunt.
 * However, if the ASD is located below the diaphragm, the signs and symptoms may be similar to mitral stenosis.
