The total cavopulmonary connection resistance: a significant impact on single ventricle hemodynamics at rest and exercise.
Little is known about the impact of the total cavopulmonary connection (TCPC) on resting and exercise hemodynamics in a single ventricle (SV) circulation. The aim of this study was to elucidate this mechanism using a lumped parameter model of the SV circulation. Pulmonary vascular resistance (1.96+/-0.80 WU) and systemic vascular resistances (18.4+/-7.2 WU) were obtained from catheterization da...
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 کاملTranscaval puncture for access to the pulmonary venous atrium after the extracardiac total cavopulmonary connection operation.
BACKGROUND Patients with surgically palliated total cavopulmonary connection are at risk for recurrent atrial arrhythmia requiring catheter ablation. Transcatheter procedures for those with extracardiac conduits (extracardiac-total cavopulmonary connection) are perhaps the most challenging because of exclusion of the venous circulation from the arrhythmia substrate. Puncture through the inferio...
متن کاملSingle catheter gravity drainage of the right atrium or right ventricle during total cardiac bypass.
The currently employed cannulations preparatory to establishing cardiac bypass with the aid of a pump-oxygenator, include isolation of the superior and inferior vena cavae over tapes and the insertion of catheters into each of these vessels. t At the onset of bypass the caval tapes are tightened around the indwelling catheters and venous drainage is effected by suction applied to the venous lin...
متن کاملEarly and intermediate-term results of the extracardiac conduit total cavopulmonary connection for functional single-ventricle hearts.
BACKGROUND/PURPOSE Fontan operation has evolved from atriopulmonary connection to total cavopulmonary connection (TCPC) due to its advantages in terms of hemodynamics and reduction of atrium-related complications. We analyzed the early and intermediate-term results of extracardiac conduit TCPC (EC-TCPC) procedure in patients with functional single ventricle to investigate the risk factors of su...
