Left superior vena cava draining into the left atrium: Clinical entities, diagnosis and surgical treatment

Area of Science:

• Congenital Heart Surgery
• Pediatric Cardiology
• Cardiac Anomalies

Background:

• Left superior vena cava (LSVC) draining into the left atrium, without a coronary sinus, is a rare congenital anomaly.
• This condition is often associated with heterotaxy syndrome and unroofed coronary sinus syndrome.
• Biventricular repair is the goal, but surgical approaches vary.

Purpose of the Study:

• To review the surgical management of LSVC draining into the left atrium.
• To discuss treatment strategies for associated heterotaxy and unroofed coronary sinus syndromes.
• To analyze outcomes of different surgical techniques in a cohort of patients.

Main Methods:

• Review of current literature on LSVC anomalies and surgical repair techniques.
• Analysis of surgical outcomes in a series of 10 patients with LSVC draining into the left atrium.
• Consideration of factors influencing surgical technique selection, including patient anatomy and associated conditions.

Main Results:

• Biventricular repair can be achieved via intracardiac or extracardiac procedures.
• Surgical technique selection depends on individual patient factors and associated pathologies.
• Accurate diagnosis and tailored surgical approach are key to successful outcomes.

Conclusions:

• Management of LSVC draining into the left atrium requires careful consideration of associated syndromes and patient-specific anatomy.
• Both intracardiac and extracardiac surgical techniques offer viable options for biventricular repair.
• Personalized surgical strategy is essential for optimal results in these complex congenital heart defects.
