Cor triatriatum dexter in children: Literature review and case report

Commentary: Cor triatriatum dexter: Persistent tissue causing protean issues!

“…3,4 The chronicity of this lesion only adds to its protean character as illustrated in this case report. 5 Tricuspid regurgitation is an unusual manifestation of cor triatriatum dexter and probably related to repetitive trauma and consequent deformation of the tricuspid valve leaflets from the bulging membrane. Although the authors have done a commendable job of collating the various case reports on this rare congenital heart defect from literature, the disease is under-reported and not as exotic as this study suggests.…”

“…Although the authors have done a commendable job of collating the various case reports on this rare congenital heart defect from literature, the disease is under-reported and not as exotic as this study suggests. 5 Most cases are asymptomatic and others coexist as part of other complex congenital heart defects. The study also raises an important question regarding the risks of conservative management in a largely asymptomatic child with well-documented membrane in the right atrium.…”

“…The right valve normally regresses between weeks 9 and 15 of gestation, leaving the crista terminalis superiorly and the Eustachian and Thebesian valves guarding the IVC and coronary sinus orifices, respectively. The persistence of the right venous valve results in partitioning the right atrium into two separate chambers (one smooth walled and the other trabeculated) and creates what is known as cor triatriatum dexter [1,2]. The smooth atrial portion receives venous blood from inferior vena cava, superior vena cava, and coronary…”

“…This is among the rarest cardiac malformation, and very limited number of cases have been reported on so far. Kalangos and colleagues 3 reviewed the literature for CTD and identified only 13 cases in addition to their report. However, the majority of CTD cases may not require surgical intervention, so the true incidence may not be known with certainty but is estimated to be <0.01%.…”
