Following the bidirectional Glenn shunt, failure of the procedure can be broadly categorized as failure of procedure, cardiac dysfunction related to surgery, or cardiac dysfunction leading to death before further surgical intervention. [8] Retrospective reviews demonstrate failure of the procedure in 6.5% of patients.
Superior Cavopulmonary Bypass (Bidirectional Glenn or Hemi-Fontan Procedure), Total Cavopulmonary Bypass (Fontan Completion Procedure). The purpose of these operations is to redirect the blood flow of the deoxygenated blood to the lungs by attaching the Vena Cava directly to the Pulmonary Artery causing the blood that flows into the lungs to be ...
Glenn procedure is a palliative surgical procedure performed for patients with Tricuspid atresia. It is also part of the surgical treatment path for hypoplastic left heart syndrome and hypoplastic right heart syndrome. [1] [2] [3] This procedure has been largely replaced by Bidirectional Glenn procedure. [citation needed]
An artificial tube or shunt can be placed from this larger vessel to the pulmonary arteries so that blood can get from the heart to the lungs. The wall between the left and right atrium can be removed to allow the mixing of oxygenated and de-oxygenated blood. [10] [11] [12] The second stage is called the hemi-Fontan or the Bidirectional Glenn ...
The second stage—the bidirectional Glenn or Hemi-Fontan (see also Kawashima procedure)—relieves some of the problems introduced by Stage I palliation. [33] In this operation, the superior vena cava is ligated from the heart and connected to the pulmonary circulation. At this time, the Blalock-Taussig or Sano shunt is taken down.
The Kawashima procedure is used for congenital heart disease with a single effective ventricle and an interrupted inferior vena cava (IVC). It was first performed in 1978 and reported in 1984. It was first performed in 1978 and reported in 1984.
In cardiology, a cardiac shunt is a pattern of blood flow in the heart that deviates from the normal circuit of the circulatory system. It may be described as right-left , left-right or bidirectional, or as systemic-to-pulmonary or pulmonary-to-systemic .
Most patients who undergo a Norwood procedure will proceed to further stages of single ventricle palliation. A second surgery, also known as the Glenn procedure, occurs at 4–6 months of age. The third surgery is the Fontan procedure, occurring when patients are 3–5 years of age. [5]
