What is Hemi Fontan?
The hemi-Fontan procedure includes association of the superior vena(e) cava(e) (SVC) with the branch pulmonary arteries, augmentation of the central pulmonary arteries, occlusion of the inflow of the SVC into the right atrium, and elimination of other sources of pulmonary blood flow.
What is Fontan procedure used for?
The Fontan procedure refers to any surgical procedure that leads to systemic flow of venous blood to the lungs without passing through a ventricle. In 1971, Fontan and Baudet (1) described a surgical procedure for repair of tricuspid atresia that built on experimental and clinical research from the 1940s.
What is a failing Fontan?
Late Fontan failure may present insidiously over years. It is a failure of medical management to interpret the absence of overt symptoms or ascites as evidence of optimal haemodynamic status in the functionally univentricular circulation.
What is a Fontan shunt?
During the Fontan procedure, the surgeon: Disconnects the inferior vena cava (IVC) from the heart and connects it to the pulmonary artery using a conduit (tube). Makes a small hole between the conduit and the right atrium. This hole (or fenestration) lets some blood still flow back to the heart.
Why is Fontan fenestrated?
Fenestration of the Fontan circuit allows for shunting of deoxygenated blood to the systemic circulation. This procedure improved the clinical outcomes of patients who are at high risk for poor Fontan results.
What is a fenestrated Fontan?
Fenestration closure after a Fontan operation is a procedure to close the hole between your child’s heart and the tunnel that takes oxygen-poor blood from the body to the lungs. The procedure is done in the heart catheterization lab.
Who invented the Fontan procedure?
Francis Fontan (2 July 1929 – 14 January 2018) was a French cardiologist and cardiothoracic surgeon best known for developing the Fontan procedure, a surgical procedure used to treat some forms of congenital heart disease.
What challenges do anesthesiologists face with Fontan physiology?
Parturients with Fontan physiology provide unique and complex challenges to anesthesiologists. Such challenges include the maintenance of a perfect balance between preload, pulmonary vascular resistance, afterload, and cardiac output in a setting of a single ventricle physiology.
What is the physiology of a patient with Fontan syndrome?
Parturients with Fontan physiology provide unique and complex challenges to anesthesiologists. Such challenges include the maintenance of a perfect balance between preload, pulmonary vascular resistance, afterload, and cardiac output in a setting of a single ventricle physiology. The physiological c …
Does Fontan physiology matter in cardiac transplant patients with ventricular dysfunction?
As reviewed elsewhere, cardiac transplant patients with Fontan physiology have inferior long-term outcomes as compared to 2-ventricle patients with isolated ventricular dysfunction. 107, 108
What is included in a preanesthetic evaluation for patients with Fontan circulation?
When conducting a preanesthetic evaluation, there are several considerations specific to patients with Fontan circulation (Table 1). The aim of the preoperative assessment is to identify factors suggestive of a failing Fontan.
