BIDIRECTIONAL CAVOPULMONARY SHUNT PDF

The original Fontan procedure included a classic superior vena cava-to-right pulmonary artery Glenn shunt. Subsequent experience demonstrated that this anastomosis was not essential and was an unnecessary commitment of the larger right pulmonary circulation to the smaller blood volume of the superior vena caval return. With application of the Fontan principle to more complex cardiac malformations, there has been a reconsideration of possible benefits of a cavopulmonary shunt in selected patients. A modified shunt from the divided end of the superior vena cava to the side of the undivided right pulmonary artery utilized in 21 patients is described. This shunt is designed to allow bidirectional pulmonary arterial distribution of both superior vena caval inflow and right atrial outflow after completion of the Fontan procedure. Twelve patients had the bidirectional shunt performed prior to a Fontan operation; five of these had a subsequent atriopulmonary connection and seven await operation.

A case is described in which a two-year-old boy, diagnosed with common atrioventricular canal, pulmonary atresia, major aortopulmonary collateral artery, asplenia, and situs inversus, underwent palliative operations for the following: unifocalization of the right major aortopulmonary collateral artery, right ventricle-to-pulmonary artery shunt, and pulmonary artery plasty.

Upon completion of the bidirectional cavopulmonary shunt operation, we addressed the stenotic lesions of the superior vena cava and left pulmonary artery, and a markedly expanded azygos vein. During this operation, the superior vena cava was divided and we performed cavopulmonary shunting with the azygos vein.

Bidirectional Cavopulmonary Shunts: Clinical Applications as Staged or Definitive Palliation

Please upgrade to a newer version of Internet Explorer or use an alternate browser such as Chrome or Firefox. The superior cavopulmonary anastomosis is the first of two operations used in a staged Fontan approach for definitive palliation of functionally single ventricle hearts. It was introduced into the palliative strategy to reduce the volume load on the hypertrophied single ventricle that pumps in parallel to the pulmonary and systemic circulations. By connecting the superior vena cava SVC to the pulmonary arteries and eliminating other sources of pulmonary blood flow, the ventricular output is directed exclusively to the systemic circulation and thus the volume work of the heart is reduced. There are two surgical techniques used to create this cavopulmonary connection prior to a completion Fontan, the bi-directional superior cavopulmonary anastomosis bi-directional Glenn and the hemi-Fontan. Because the first stage of the Fontan is preparatory for the final one, the cavopulmonary anastomosis should facilitate construction of the completion Fontan.

Outcomes after bidirectional cavopulmonary shunt in infants less than 6 months old.

The Glenn procedure is done when not enough blood is getting to the lungs. Learn about this procedure and the risks associated with it. This procedure is done when only one ventricle works properly and not enough blood is getting to the lungs. The superior vena cava returns blood from the upper half of the body to the right atrium. This procedure involves disconnecting the superior vena cava from the right atrium and connecting it to the right pulmonary artery. This lets the blue, deoxygenated blood flow directly to both lungs, bypassing the heart. This procedure is usually one in a series of operations.
