Cor triatriatum dexter in adults?

Rev Esp Cardiol. 2010;63(12):1510-6 1515 On the other hand, in the fetus and in childhood it is exceptional to find an obstructive CTD without associate anomalies, and in our experience it is also exceptional to find it associated with right-sided heart malformations. That perception is corroborated by the lack of description of this issue, limited to a few cases published in literature.4-6 In addition, the published cases at the adult age are limited to non obstructive CTD and without attention to detail.7 For these reasons we think that categorizing the spectrum of residual right valve of the venous sinus must not be given too much importance and that functional analysis must be sufficient to rule out obstruction of the flow at this level. The reality is that in our daily practice, and supported by the literature, it is very frequent to find prominent Chiari net, Eustachian or Thebesian valve simulating a CTD; sometimes there are even non significant flow accelerations at these levels without any type of repercusion.8 In conclusion, we want to note, as did SanchezBrotons et al1, that the findings of residual right valve of the venous sinus are frequent in the normal population, and are not sufficient to diagnose a CTD. In our opinion, it is necessary to add that we must be skeptical at the time of making this diagnosis in adults and most of all when significant obstruction to the venous flow is not demonstrated.
