CPT® Code 33945

The procedure described by CPT® Code 33945 refers to a heart transplant, which may include the removal of the recipient's diseased heart, known as cardiectomy. This complex surgical operation is typically performed through a median sternotomy, which involves making an incision along the breastbone to access the heart. During the procedure, cardiopulmonary bypass is established to take over the function of the heart and lungs, allowing the surgeon to operate on a still and bloodless field. In most cases, an orthotopic heart transplant is performed, where the majority of the recipient's heart is excised, while leaving parts of the atria intact. The surgical steps involve carefully opening the right atrium and making incisions to facilitate the connection of the donor heart to the recipient's remaining cardiac structures. This intricate process ensures that the donor heart is properly anastomosed to the recipient's atria and major vessels, allowing for effective blood circulation post-transplant. The procedure concludes with the patient being weaned off the cardiopulmonary bypass, placement of chest tubes, and closure of the chest incisions, marking the end of a critical and life-saving intervention.
