Total cavopulmonary connection flow with functional left pulmonary artery stenosis: angioplasty and fenestration in vitro.
BACKGROUND In our multicenter study of the total cavopulmonary connection (TCPC), a cohort of patients with long-segment left pulmonary artery (LPA) stenosis was observed (35%). The clinically recognized detrimental effects of LPA stenosis motivated a computational fluid dynamic simulation study within 3-dimensional patient-specific and idealized TCPC pathways. The goal of this study was to qua...
متن کاملPulmonary and caval flow dynamics after total cavopulmonary connection.
OBJECTIVE To assess flow dynamics after total cavopulmonary connection (TCPC). DESIGN Cross-sectional study. SETTING Aarhus University Hospital. PATIENTS Seven patients (mean age 9 (4-18) years) who had previously undergone a lateral tunnel TCPC mean 2 (0. 3-5) years earlier. INTERVENTIONS Pressure recordings (cardiac catheterisation), flow volume, and temporal changes of flow in the la...
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 کاملHemodynamic effects of left pulmonary artery stenosis after superior cavopulmonary connection: a patient-specific multiscale modeling study.
OBJECTIVE Currently, no quantitative guidelines have been established for treatment of left pulmonary artery (LPA) stenosis. This study aims to quantify the effects of LPA stenosis on postoperative hemodynamics for single-ventricle patients undergoing stage II superior cavopulmonary connection (SCPC) surgery, using a multiscale computational approach. METHODS Image data from 6 patients were s...
متن کاملSildenafil before total cavopulmonary connection.
The surgical palliation first described by Fontan and Baudet 1 as Fontan-type operation or total cavopulmonary connection (TCPC) is based on a connection between the systemic venous system and the pulmonary artery tree, excluding the pumping function of the main ventricle. Under these circumstances, the main ventricular chamber acts as a single ventricle, supplying anterograde flow and aspirati...
