In 1958, William Glenn reported a successful superior vena cava to right pulmonary artery anastomosis (Glenn procedure) for tricuspid atresia in the New England Journal of Medicine. [12] The bidirectional Glenn is a modification where the SVC connects proximally to the bifurcation of the pulmonary arteries. [13]
Tricuspid atresia is a form of congenital heart disease whereby there is a complete absence of the tricuspid valve. [2] Therefore, there is an absence of right atrioventricular connection. [2] This leads to a hypoplastic (undersized) or absent right ventricle. This defect occurs during prenatal development, when the heart does not finish ...
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]
The Fontan Kreutzer procedure is used in pediatric patients who possess only a single functional ventricle, either due to lack of a heart valve (e.g. tricuspid or mitral atresia), an abnormality of the pumping ability of the heart (e.g. hypoplastic left heart syndrome or hypoplastic right heart syndrome), or a complex congenital heart disease where a bi-ventricular repair is impossible or ...
By the late 2000s, the procedure was employed in situations where the right ventricle is bigger than the left ventricle and the left ventricle connects to the pulmonary artery instead of the aorta; examples include double inlet left ventricle, TGA with tricuspid atresia and TGA with hypoplastic left heart syndrome. [2]
Variations are also used for palliation of mitral and tricuspid atresia [6] and subsets of transposition of great arteries (TGA). [7] Without surgical repair, infants born with a single ventricle cardiac defect face almost certain mortality in the first year of life.
