Operation Definition
Freeing a body part from an abnormal physical constraint by cutting or by the use of force
Procedure Overview
Release procedures free a part of the heart or a great vessel from tissue that is pressing on it or restricting its movement, without cutting into or removing the part itself. The most familiar example is dividing the pericardium in constrictive pericarditis, where a stiffened or scarred sac squeezes the heart and limits how well it can fill with blood. Adhesions from prior cardiac surgery or scar tissue compressing a great vessel are also treated this way.
The surgeon's job in a Release procedure is to cut or otherwise separate the constraining material while leaving the heart or vessel wall untouched, restoring normal expansion and contraction or normal vessel diameter. Patients with symptoms of poor cardiac filling despite a structurally sound heart, or with a vessel that is being pinched by fibrous bands, are typical candidates.
Anatomy & Axis Detail
Coronary Artery, Three Arteries
Freeing three coronary arteries in one operative episode typically reflects extensive epicardial disease, such as widespread constrictive bands from chronic pericarditis or multiple myocardial bridges discovered during exploration for otherwise unexplained ischemia. The surgeon systematically dissects the fibrofatty and muscular tissue encasing each of the three vessels, taking care to preserve the arterial wall and adjacent branches while relieving the external squeeze. Because this scope approaches the extent seen in multivessel coronary disease generally treated by bypass, careful documentation distinguishing release from bypass or angioplasty is important. The three-artery designation is reserved specifically for cases where three distinct coronary arteries each undergo their own separate freeing from surrounding constrictive tissue during the same procedure.
Approach: Percutaneous
Percutaneous describes entry by needle or instrument puncture through the skin or mucous membrane to reach the site of the procedure, without cutting the tissue open or using a visualizing scope. It differs from Open in that the site itself is never exposed, and from Percutaneous Endoscopic in that no endoscope is used to see internal structures. Common examples include needle biopsies and injections.
Coding & Documentation
The operative report must show that the constraining material itself, not the heart or vessel, was the target of the cutting or dissection, and that the constraining material was left in the body rather than removed. If any of that tissue is excised and sent to pathology, part of the case may need to be captured separately. Coders should verify the specific body part freed, since pericardial release and vessel release use different body part values within the Heart and Great Vessels system. A common assignment error is coding Release when adhesions are lysed as an incidental step during another surgery rather than as the intended procedure; in that case it may not warrant separate coding.
