A 10-year-old female with Cor triatriatum sinister (CTS): a rare case report and literature review from Syria.

INTRODUCTION AND IMPORTANCE

Cor triatriatum sinister (CTS) is an uncommon heterogeneous congenital cardiac defect that may manifest in adulthood when symptomatic blockage manifests due to a change in hemodynamic physiology or when a condition such as atrial fibrillation (AF) arises. The incidence of cor triatriatum with cardiomyopathy and congenital heart illness ranges from 0.1 to 0.4%.

CASE PRESENTATION

The Department of Cardiology examined a 10-year-old girl for a diastolic murmur. The patient's medical history was ordinary, and no previously known co-morbid illnesses were present. Pneumonia was the patient's original medical condition. A cardiac murmur was also discovered during the physical examination, and the patient was forwarded for more research. Physical examination revealed just a diastolic murmur, which was noteworthy. The patient's care plan includes routine echocardiographic monitoring. Since the deformity was not clinically significant, surgical repair was not advised.

CLINICAL DISCUSSION

It is unclear what caused this flaw. A full, incomplete, or fenestrated septum may be the result of the common pulmonary vein failing to merge with the left atrium during embryonic development. The existence of a fibromuscular membrane, which separates the left atrium (LA) into two chambers-the proximal chamber receiving the pulmonary veins (PVs) and the distal chamber contains the mitral valves and LA appendages defines the disease.

CONCLUSION

The diagnostic procedure should be carried out in the optimal settings, however, in cases of frail health systems, employing accessible alternatives might help the early diagnosis. Early referral to a cardiologist is required in case of CTS suspicion.
