Complications after a Bidirectional Cavopulmonary Anastomosis with Accessory Sources of Pulmonary Blood Flow

Distribution of pulmonary blood flow after cavopulmonary anastomosis (Glenn operation).

Theoretical optimization of pulmonary-to-systemic flow ratio after a bidirectional cavopulmonary anastomosis.

A univentricle with parallel pulmonary and systemic circulations is inherently inefficient because mixing of pulmonary and systemic venous return occurs. Thus a cavopulmonary anastomosis is used as a staged palliative procedure to reduce volume overload in patients with cyanotic congenital heart disease. On the basis of oxygen uptake and consumption, an equation was derived that related cardiac...

Bidirectional cavopulmonary shunt with additional pulmonary blood flow.

There are some controversies regarding the usefulness of leaving additional pulmonary blood flow when establishing a bidirectional cavopulmonary shunt. From April 2002 to September 2008, 13 patients (mean age, 24 +/- 16 months) underwent a bidirectional cavopulmonary shunt procedure with fine adjustment of additional pulmonary blood flow, as an intermediate step before the Fontan operation. The...

Bidirectional cavopulmonary anastomosis.

SLAVIK AND HIS COLLEAGUES 1 OFFER A THOUGHTful discussion of the subject of the bidirectional cavopulmonary anastomosis, and offer a useful review of the primary papers. The authors make the important point that these patients are not a homogeneous cohort. The argument about where to measure the pulmonary arteries is a bit academic, and the strengths and weaknesses of various methods have been ...

Bidirectional cavopulmonary anastomosis.

The Fontan operation has been used to palliate patients with a functional single ventricle. In many such patients the operative risk for a Fontan procedure is high. The bidirectional cavopulmonary anastomosis (BCPA) is a useful intermediate palliative procedure before Fontan correction. It may reduce the deleterious sequelae of chronic hypoxaemia and long-term ventricular overload, thus yieldin...
