Cor triatriatum dexter

Area of Science:

• Cardiology
• Congenital Heart Disease
• Cardiac Anatomy

Background:

• Cor triatriatum dexter (CTD) is an exceptionally rare congenital heart anomaly, occurring in less than 0.01% of the population.
• This condition arises from the incomplete regression of the right valve of the sinus venosus during embryonic development.
• CTD results in an anomalous septum dividing the right atrium, impacting blood flow dynamics.

Purpose of the Study:

• To highlight the rarity and embryological origin of Cor triatriatum dexter.
• To emphasize the diagnostic utility of echocardiography in identifying CTD.
• To discuss the implications for clinical decision-making in patients with this anomaly.

Main Methods:

• Review of existing literature and case reports on Cor triatriatum dexter.
• Emphasis on the role of echocardiography, particularly with color Doppler, in anatomical assessment.
• Discussion of diagnostic criteria and imaging findings associated with CTD.

Main Results:

• Cor triatriatum dexter is confirmed as an extremely rare cardiac malformation.
• Echocardiography with color Doppler demonstrates high efficacy in visualizing the anomalous septation within the right atrium.
• The findings underscore the importance of recognizing this anomaly for appropriate management.

Conclusions:

• Cor triatriatum dexter is a rare congenital anomaly with specific embryological underpinnings.
• Echocardiography is the primary diagnostic modality for CTD, providing essential anatomical and functional information.
• Accurate diagnosis via echocardiography is crucial for guiding clinical management and surgical considerations.
