2018年2月1日 · The Fontan procedure is the final procedure in staged palliation for patients with functional single-ventricle physiology. The goal of the procedure is to separate systemic and pulmonary blood flow by directing systemic venous return through the Fontan connection to the pulmonary arteries and the lungs without ventricular contribution.

Using a baffle fenestration or adjustable atrial septal defect in a modified Fontan operation is now a common practice. Hemodynamic benefits include increased cardiac index and systemic oxygen transport, as well as lower systemic venous pressure. The incidence and duration of pleural effusions is al …

Fontan的想法是把上下腔静脉直接和肺动脉相连通，这样的话，从全身各处收回来的血液不用到达心室，而是可以直接进入肺动脉，进行肺循环。 而且，Fontan的想法还有另一个目的。

2022年7月4日 · Patients with a fenestrated baffle or conduit are frequently maintained on pharmacologic anticoagulation in order to reduce the risk of stroke from paradoxical emboli 8. The procedure was originally suggested in 1971 by F Fontan and E Baudet as a correction for tricuspid atresia.

2012年11月20日 · The modified Fontan can be performed by the use of an extracardiac conduit approach or a lateral tunnel approach. The extracardiac Fontan uses an external conduit to anastomose the inferior vena cava into the pulmonary arteries, whereas a lateral tunnel Fontan uses a baffle within the right atrium . Because the systemic venous pathway is ...

The Fontan procedure or Fontan–Kreutzer procedure is a palliative surgical procedure used in children with univentricular hearts. It involves diverting the venous blood from the inferior vena cava (IVC) and superior vena cava (SVC) to the pulmonary arteries .

2017年7月14日 · Preprocedural cardiac computed tomography (CT) should be performed in all patients with Fontan circulation and an intra-atrial baffle. Cardiac CT is very helpful for identification of the cardiac and vascular anatomy and 3-dimensional electroanatomic mapping (Figures 1A, 1B, and 1C).

The Fontan circulation is the definitive surgical palliation for single-ventricle circulations. Originally described for the treatment of absent right atrioventricular connection, the technique has now been extended to many complex cardiac abnormalities with only one well-developed ventricle.

2025年2月22日 · Fontan operation (or total cavopulmonary connection, TCPC) is the final palliation for different CHDs with univentricular physiology. It directs the systemic venous return of the lower part of the body to the lung. Operation performed typically around 2.5–4 years of age.

Intracardiac baffle often goes along with septation. Baffles are structures that direct the flow of something—in this case, blood. In the heart, baffles are created with artificial material to separate the sides of the heart or to lead the blood down a desired pathway, helping to reroute it …
