Cardioembolic stroke in a young male with cor triatriatum sinister: a case report.

This is the 13th reported case of CTS associated with stroke. In most previous cases evidence of blood stasis or frank thrombus was associated with the CTS membrane, and/or existing AF was noted. In this case, none of these were identified, particularly highlighting the surreptitious risk of CTS. In addition, the presence of potential protein C deficiency in this case compounded the risk for thromboembolism and factored into multidisciplinary management decisions.
