[Echocardiography in cor triatriatum dexter]
Insights
Cor triatriatum dexter (CTD) is a rare heart defect where the right atrium is divided. Advanced echocardiography is crucial for diagnosing this complex congenital anomaly.
Area of Science:
- Cardiology
- Pediatric Cardiology
- Congenital Heart Disease
Background:
- Cor triatriatum dexter (CTD) is a rare congenital heart defect characterized by the right atrium's subdivision due to a persistent sinus venosus valve.
- This anomaly can lead to cyanosis and presents diagnostic challenges.
Observation:
- Two pediatric patients with CTD, diagnosed and treated in 1979 and 1992, are presented.
- Initial misdiagnosis of one patient as cor triatriatum sinister highlights the complexity.
Findings:
- Two-dimensional and Doppler echocardiography, alongside cardiac catheterization and surgery, were used to delineate the anatomical and physiological aspects of CTD.
- High-resolution imaging confirmed the presence of an atrial membrane and its effects.
Implications:
- This case series underscores the diagnostic utility of advanced echocardiographic techniques in evaluating complex congenital heart defects like CTD.
- Accurate diagnosis through imaging is vital for appropriate surgical planning and patient management.
Abstract:
"Cor triatriatum dexter" (CTD) is an unusual cyanotic cardiac defect in which the right atrium is subdivided into two distinct chambers due to the persistence of the "sinus venosus" valve. Two patients with CTD ho were evaluated and treatment in 1979 and 1992 are described: the first one, had total anomalous pulmonary venous return to the coronary sinus or "cor triatriatum sinister" as preoperative diagnosis based on M-mode echocardiographic findings. The presence of a membrane inside the right atrium was suspected on cineangiogram. The other one had a preoperative diagnosis of CTD. Anatomic relationships and physiological effects were established by two dimensional and Doppler ultrasonography and confirmed at cardiac catheterization and surgery. High resolution two dimensional echocardiography coupled with Doppler ultrasonography has a definite role in the study of this heart defect.
