Closed-Loop CFD Analysis of the Fontan Cardiovascular Circulation
… those infants have a single ventricle (SV). The Fontan operation, which is a procedure to create a harmonious circulation in SV patients, has been performed for a long time to save the newborn patients. In this procedure the superior vena cava and inferior vena cava, which carry the oxygen-poor …

Laboratory Development of a Self-Powered Fontan for Treatment of Congenital Heart Disease
… have only a single functioning ventricle. The Fontan operation has served as a palliation for this anomaly for decades, but the surgery entails multiple complications and survival rate is less than 50% by adulthood. A rapidly testable novel alternative is proposed by creating a bifurcating …

Lumped Parameter Model for a Self Powered Fontan Palliation of the Hypoplastic Left Heart Syndrome
… 8% have a single functioning ventricle. The Fontan surgical procedure, where the superior and inferior venous returns are connected directly to the pulmonary arteries to allow the single functioning ventricle to perfuse the systemic circulation, has been around for decades, yet the patients …

Enfermedad hepática asociada a Fontan: caracterización de casos en hospital de cuarto nivel en Bogotá, Colombia
… La hepatopatía asociada al síndrome de Fontan (FALD, por sus siglas en inglés) es una complicación frecuente en pacientes con cirugía de Fontan, y su detección temprana es crucial para un manejo adecuado. Se trata de una patología emergente que se ha asociado con un aumento en la …

A multimodal approach to investigate the effects of respiration on Fontan flow to inform strategies for circulatory support
… ventricle physiology is estimated to be 1/3000. Fontan physiology is the final palliative stage for a series of congenital heart diseases resulting in a single ventricle. Resulting hemodynamics are not well characterized and remain poorly understood. Hence, mid-term survival rates remain high and …

In-Vitro and In-Silico Investigations of Alternative Surgical Techniques for Single Ventricular Disease
… and third stage i.e. Comprehensive stage II and Fontan procedure of the existing three-staged surgical approach serving as a palliative treatment for this anomaly, entails multiple complications and achieves a survival rate of 50%. Hence, to reduce the morbidity and mortality rate associated with …

Multi-Scale Fluid Flow Analysis of the Cardiovascular System
… left heart syndrome (HLHS). To this end, the Fontan operation which is a procedure to generate a harmonic blood flow in single functioning ventricle patients has been executed to palliate HLHS patients. In this operation, the inferior vena cava (IVC) and the superior vena cava (SVC), carrying …

Thrombosis in Children
… heart defects were evaluated before and after Fontan surgery, and the results of follow-up global coagulation tests in patients and controls were analyzed. Results and conclusions: The present studies showed a bimodal age distribution in pediatric thrombosis patients in Sweden, with peaks in …

Untersuchung der myokardialen Deformation des singulären linken Ventrikels mittels 2-dimensionaler Feature Tracking Magnetresonanztomographie
… Patienten mit singulärem linken Ventrikel in der Fontan-Zirkulation mittels 2D-MRT Feature Tracking und 2D-Speckle Tracking Echokardiographie untersucht und mit gesunden Kontrollen verglichen. Die meisten Patienten waren der NYHA-Klasse I zuzordnen und hatten eine normale Ejektionsfraktion (Median …

Design of Percutaneous Dual Propeller Pump to assist Patients with Single Functional Ventricle
… palliation procedure, including the final Fontan Completion, is often adopted by surgeons to treat patients with such CHDs. However, the most common outcome of this surgery, an extra-cardiac total cavopulmonary connection (TCPC), formed by suturing the inferior vena cava (IVC) and superior …

Hemodynamic Optimization of a Passive Assist Total Cavopulmonary Connector for ages 1-20
… to address right ventricular dysfunction is the Fontan procedure, which connects the superior and inferior vena cava directly to the left and right pulmonary arteries bypassing the right atrium. However, this is not the most efficient configuration from a hemodynamics perspective. The goal of …
