Cor triatriatum dexter: a rare incidentaloma

Area of Science:

• Cardiology
• Congenital Heart Disease
• Cardiac Anatomy

Background:

• Cor triatriatum dexter (CTD) is an exceptionally rare congenital cardiac anomaly.
• It arises from the persistence of the right valve of the sinus venosus.
• CTD involves abnormal septation of the right atrium, leading to potential obstruction.

Observation:

• A 68-year-old woman presented with complaints of ventricular ectopic beats.
• Diagnostic workup was initiated for further evaluation of her cardiac condition.
• The patient's presentation prompted investigation into potential underlying cardiac anomalies.

Findings:

• The diagnostic process aimed to characterize the cause of the patient's symptoms.
• Multimodal diagnostic modalities are essential for accurate CTD diagnosis.
• Identifying CTD is crucial for appropriate patient management and treatment strategies.

Implications:

• Early and accurate diagnosis of CTD is vital for preventing complications.
• Understanding CTD's presentation in adults is important for clinicians.
• This case underscores the need for comprehensive cardiac evaluation in patients with unexplained arrhythmias.
