Single Ventricle (Univentricular Heart) is a complex congenital heart defect in which a child is born with only one functional ventricle responsible for pumping blood to both the body and the lungs. This condition requires a precise, multi-stage surgical approach to improve blood circulation efficiency.

Dr. Mahmoud El-Degwy Ahmed emphasizes that managing this condition requires a well-structured staged surgical plan aimed at improving quality of life and reducing complications.

What is Single Ventricle?

Single ventricle is a congenital heart defect in which only one pumping chamber functions effectively instead of two, leading to mixing of oxygenated and deoxygenated blood.

Why Does the Patient Need Surgical Intervention?

Dr. Mahmoud El-Degwy Ahmed explains that surgical intervention is necessary to regulate blood flow and reduce pressure on the heart and lungs, thereby gradually improving circulatory function.

Stages of Surgical Treatment for Single Ventricle

Stage 1: Initial Palliative Surgery

This stage aims to optimize pulmonary blood flow or reduce it depending on the condition. It is usually performed in the early months of life.

Stage 2: Glenn Procedure

In this stage, the superior vena cava is directly connected to the pulmonary artery, reducing the workload on the single ventricle.

Stage 3: Fontan Procedure

This is the final stage, where all deoxygenated blood is redirected to the lungs without passing through the heart, significantly improving circulation efficiency.

Outcomes and Success Rates of Single Ventricle Surgery

Dr. Mahmoud El-Degwy Ahmed states that success rates depend on the patient’s overall condition and adherence to post-operative follow-up, with generally favorable long-term outcomes.

Post-Operative Follow-Up

  • Regular follow-up with a cardiologist
  • Routine heart function assessments
  • Avoidance of excessive physical exertion in early stages
  • Adherence to prescribed medications

Conclusion

Single ventricle surgery is a highly delicate multi-stage procedure that requires significant expertise. Dr. Mahmoud El-Degwy Ahmed emphasizes that proper surgical planning and continuous follow-up are key to achieving optimal outcomes.
