Operation Definition
Putting in or on biological or synthetic material to form a new body part that to the extent possible replicates the anatomic structure or function of an absent body part
Procedure Overview
Creation procedures in the heart and great vessels involve building a new anatomic structure using biological tissue or synthetic material when a structure is absent or cannot be repaired by other means. Rather than repairing or replacing an existing part, the surgeon fashions a substitute intended to approximate the shape and function of what would normally be there. In cardiac surgery this typically comes up in complex congenital reconstructions, where a chamber, valve, or vascular connection never developed properly and must be constructed essentially from scratch using patch material, conduit, or grafted tissue.
Patients and families encounter this concept most often in the context of staged single-ventricle repairs or other rare structural anomalies, where surgeons build a functional pathway that nature did not provide. The goal is to restore circulation as close to normal physiology as achievable, understanding that a created structure is an approximation rather than a true native part.
Anatomy & Axis Detail
Aortic Valve
Creation of an aortic valve is performed to establish a functioning valve where the anatomic valve is absent, severely malformed, or unsalvageable, most notably during a Ross procedure in which the patient's own pulmonary valve is relocated to the aortic position, or when a prosthetic valve substitute is implanted to construct a valve mechanism rather than simply repair or replace an existing one. This distinction matters because the aortic valve endures the highest pressures in the systemic circulation and sits immediately adjacent to the coronary ostia, so the newly created valve must be sized and seated precisely to maintain coronary blood flow and prevent regurgitation or stenosis. Documentation must specify the device value reflecting the type of substitute used, whether autologous tissue such as the pulmonary autograft, nonautologous tissue, or a synthetic prosthesis, since this differentiates Creation from the more common Replacement procedures coded elsewhere for this valve.
Approach: Open
Open approach means the surgeon cuts through skin, mucous membrane, or other tissue layers to physically expose the target site to view before performing the procedure. It gives direct visualization and hands-on access, distinguishing it from Percutaneous approaches where instruments pass through a small puncture without exposing the site. Open is typical for procedures needing wide access, such as most laparotomies.
Device: Synthetic Substitute
Synthetic Substitute designates a device made from manufactured, non-biologic material, such as mesh or prosthetic components, used to replace or augment a body part. It is distinguished from the two tissue substitute categories by its artificial composition, which carries different considerations for integration and long-term durability than biologic grafts.
Qualifier: Truncal Valve
This qualifier identifies the truncal valve, the single valve serving a persistent truncus arteriosus, as the object of a valve procedure. It is distinguished from separate aortic and pulmonary valve qualifiers, which apply only once the great vessels and their valves have been surgically separated into two distinct outflows.
Coding & Documentation
This root operation is used sparingly in the heart and great vessels body system, and documentation must clearly describe that a new structure was fabricated rather than repaired, replaced, or bypassed - operative notes should specify the material used and confirm no native equivalent existed to work from. Coders should be alert to conflating Creation with Replacement, since both involve placing material into the body: Replacement swaps out an existing body part, while Creation applies only when the part being formed did not previously exist in that configuration. Because this operation is uncommon outside select congenital and reconstructive contexts, coders should verify against current facility coding guidance before assigning it and avoid defaulting to it whenever unfamiliar graft or patch material appears in the note.
