Summary
Cor triatriatum sinister, a heart defect, was surgically treated in 21 pediatric patients. Surgical correction showed a 62% survival rate, with excellent long-term outcomes in most survivors.
Area of Science:
- Pediatric Cardiology
- Congenital Heart Disease
- Cardiac Surgery
Background:
- Cor triatriatum sinister is a rare congenital heart defect characterized by a membrane subdividing the left atrium.
- This condition can lead to significant hemodynamic compromise in infants and children.
Purpose of the Study:
- To review the treatment outcomes of pediatric patients with cor triatriatum sinister.
- To evaluate the efficacy of different surgical approaches based on patient age.
Main Methods:
- Retrospective analysis of 21 patients treated over 23 years at two institutions.
- Classification of cardiac anatomy and associated anomalies.
- Surgical correction techniques and assessment of survival and long-term results.
Main Results:
- Twenty-one patients (1 day to 156 months) were treated for cor triatriatum sinister.
- Surgical correction in 13 patients resulted in an 8-patient (62%) survival rate.
- Long-term follow-up showed excellent results in 7 of 8 survivors (88%).
Conclusions:
- Surgical correction of isolated cor triatriatum sinister offers a chance for good long-term outcomes.
- A right atrial approach is recommended for infants and small children.
- A left atrial approach may be suitable for older children.
