CPT® Code 33622

Reconstruction of complex cardiac anomaly (eg, single ventricle or hypoplastic left heart) with palliation of single ventricle with aortic outflow obstruction and aortic arch hypoplasia, creation of cavopulmonary anastomosis, and removal of right and left pulmonary bands (eg, hybrid approach stage 2, Norwood, bidirectional Glenn, pulmonary artery debanding)

Reconstruction of a complex cardiac anomaly involves a surgical procedure aimed at correcting significant congenital heart defects, particularly those that affect the normal flow of blood through the heart and to the body. This specific procedure, identified by CPT® Code 33622, is typically performed as the second stage of a hybrid approach to treatment. Such anomalies often include conditions like hypoplastic left heart syndrome, where the left side of the heart is underdeveloped, leading to a reliance on the right ventricle to manage both pulmonary and systemic blood flow. The surgical intervention is critical to establish a more balanced circulation, ensuring that adequate blood reaches both the lungs for oxygenation and the rest of the body to support its functions. The procedure is complex and requires careful planning and execution, as it involves multiple steps to reconstruct the heart's anatomy and improve its functionality. The use of median sternotomy allows access to the heart, and techniques such as cardiopulmonary bypass and hypothermic circulatory arrest are employed to facilitate the surgery while minimizing risks to the patient. Overall, this reconstruction aims to enhance the patient's quality of life and improve long-term outcomes for those with severe cardiac anomalies.
