Total Anomalous Pulmonary Venous Return (TAPVR) Surgery
Total Anomalous Pulmonary Venous Return (TAPVR) is a rare congenital heart defect where the pulmonary veins, which normally carry oxygen-rich blood from the lungs to the left atrium, connect abnormally to the right atrium or other veins.
This misconnection causes oxygenated and deoxygenated blood to mix, leading to low oxygen levels in the body (cyanosis). TAPVR is a critical condition that requires surgical correction soon after birth.
Types of TAPVR
TAPVR is classified into four main types, based on where the pulmonary veins connect abnormally:
- Supracardiac TAPVR Veins connect above the heart, often to the superior vena cava.
- Cardiac TAPVR Veins connect directly to the right atrium or coronary sinus.
- Infracardiac TAPVR Veins connect below the diaphragm, often causing severe obstruction.
- Mixed TAPVR Combination of the above types.
Why is TAPVR Surgery Needed?
Without surgery, TAPVR can cause:
- Severe cyanosis (bluish skin from lack of oxygen)
- Breathing difficulties in newborns
- Poor growth and development
- Congestive heart failure
- High risk of early death
How is TAPVR Surgery Performed?
The surgery is performed under general anesthesia by a pediatric cardiac surgeon. It involves:
- Reconnecting pulmonary veins to the left atrium so oxygenated blood flows correctly.
- Closing abnormal connections between veins and the right atrium.
- Repairing any associated heart defects, such as atrial septal defects (ASD).
Benefits of TAPVR Surgery
- Restores normal oxygen circulation
- Improves heart and lung function
- Reduces symptoms such as rapid breathing and fatigue
- Enhances growth and development in children
- Offers long-term survival and quality of life
Risks and Complications
Though life-saving, surgery carries some risks:
- Bleeding or infection
- Pulmonary vein narrowing (stenosis)
- Arrhythmias (irregular heartbeat)
- Need for reoperation in rare cases
- Heart failure (uncommon with successful repair)
Recovery After TAPVR Surgery
- Hospital stay: typically 2 to 3 weeks depending on the child’s condition
- Initial care in the pediatric cardiac ICU
- Long-term medications may be required
- Regular follow-ups with a pediatric cardiologist
- Healthy growth expected with proper monitoring
