Cor triatriatum sinister with dilated coronary sinus from persistent left superior vena cava: a novel operative...

Area of Science:

• Cardiology
• Congenital Heart Disease
• Surgical Innovation

Background:

• Persistent left superior vena cava (PLSVC) is a congenital anomaly often associated with cor triatriatum.
• PLSVC can lead to left atrial outflow obstruction due to drainage into a dilated coronary sinus, impinging on the left atrium.
• Surgical correction of cor triatriatum may not fully resolve residual obstruction caused by PLSVC.

Observation:

• A patient presented with symptomatic cor triatriatum and associated PLSVC.
• The patient experienced persistent left atrial outflow obstruction despite previous surgical intervention for cor triatriatum.
• The anatomical challenges posed by the confluence of PLSVC and cor triatriatum were noted.

Findings:

• A novel surgical technique was successfully employed to address the residual left atrial outflow obstruction.
• The described approach specifically targets the complex interaction between PLSVC and cor triatrium.
• This intervention aimed to alleviate the impingement on the left atrial posterior wall.

Implications:

• This novel surgical treatment offers a potential solution for complex cases of cor triatriatum with PLSVC.
• The findings may guide surgical strategies for similar congenital heart malformations.
• Further investigation into this technique could improve outcomes for patients with combined cardiac anomalies.
