Supravalvular stenosing ring of the left atrium.
The Annals of Thoracic Surgery
|May 11, 1976
Summary
Supravalvular stenosing ring of the left atrium is a rare congenital anomaly. Early diagnosis and recognition are crucial for managing patients with this condition, especially when associated with other cardiac defects.
Area of Science:
- Cardiology
- Congenital Heart Disease
- Cardiac Surgery
Background:
- Supravalvular stenosing ring of the left atrium is a rare congenital anomaly.
- Its association with other cardiac malformations, such as ventricular septal defect and Wolff-Parkinson-White syndrome, is exceptionally uncommon.
Observation:
- Two cases of supravalvular stenosing ring of the left atrium are presented.
- In one patient, the diagnosis was suspected but not confirmed preoperatively, leading to death from pulmonary embolism post-correction.
- In the second patient, a missed preoperative diagnosis contributed to mortality following tetralogy of Fallot correction.
Findings:
- The study discusses differential diagnoses for left atrial flow obstruction and highlights the distinct microscopic features differentiating supravalvular stenosing ring from cor triatriatum.
- Cardiac catheterization, angiography, and echocardiography are emphasized as valuable diagnostic tools.
Implications:
- Failure to recognize and diagnose supravalvular stenosing ring in patients with coexisting cardiac anomalies can have fatal consequences.
- Prompt and accurate diagnosis is vital for appropriate management and improved patient outcomes.
