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...
متن کاملPulmonary blood flow after total cavopulmonary shunt.
The pattern of pulmonary blood flow was studied in three patients after a total cavopulmonary shunt procedure. Doppler studies showed a phasic pattern of flow which varied with the respiratory cycle. Pulmonary blood flow was increased with normal inspiration, and was much augmented by the Mueller manoeuvre. This suggests that flow was occurring when a negative intrathoracic pressure was generat...
متن کاملBidirectional cavopulmonary connection without additional pulmonary blood flow in patients below the age of 6 months.
OBJECTIVE The bidirectional cavopulmonary connection (BCPC) has shown excellent results as an intermediate step towards permanent palliation in functional single ventricle morphology. The optimal timing of the BCPC, though, remains unclear. This investigation focuses on results in a subgroup of patients under 6 months of age. METHODS Between 2001 and 2006, 124 patients received a BCPC followe...
متن کاملBidirectional cavopulmonary connection without additional pulmonary blood flow as an ideal staging for functional univentricular hearts.
OBJECTIVE Our institutional policy differs from others substantially, as we never leave any additional blood flow at the time of performing bidirectional cavopulmonary connection (BCPC). The aim was to evaluate the influence of this strategy on hemodynamics and pulmonary artery development. METHODS Between 2001 and 2006 a total of 124 patients had completion to a total cavopulmonary connectio...
متن کاملPulmonary vein flow pattern in patients with bidirectional cavopulmonary connection or Fontan circuit
Background Typical flow velocities in the extraparenchymal pulmonary veins demonstrate two major antegrade flow waves: a biphasic systolic wave (S1 and S2) and a monophasic early diastolic wave (D) (Figure 1). There is often flow reversal during atrial systole (a). There is agreement that the forward diastolic pulmonary vein flow wave is caused by left ventricular relaxation and opening of the ...
