Nonlinear power loss during exercise in single-ventricle patients after the Fontan: insights from computational fluid dynamics.
BACKGROUND We previously demonstrated that power loss (PL) through the total cavopulmonary connection (TCPC) in single-ventricle patients undergoing Fontan can be calculated by computational fluid dynamic analysis using 3-dimensional MRI anatomic reconstructions. PL through the TCPC may play a role in single-ventricle physiology and is a function of cardiac output. We hypothesized that PL throu...
متن کاملHaemodynamic comparison of a novel flow-divider Optiflo geometry and a traditional total cavopulmonary connection.
OBJECTIVES The total cavopulmonary connection (TCPC), the current palliation of choice for single-ventricle heart defects, is typically created with a single cylindrical tunnel or conduit routing inferior vena caval (IVC) flow to the pulmonary arteries. Previous studies have shown the haemodynamic efficiency of the TCPC to be sub-optimal due to the collision of vena caval flow, thus placing an ...
متن کاملExercise performance after univentricular palliation
Background The optimal timing, need for primary/staged procedure in patients undergoing univentricular palliation, is debatable. Aims We performed this study to assess the exercise performance of patients undergoing various forms of univentricular palliation. Setting and Design This was a retrospective, prospective comparative study conducted at a multispecialty tertiary referral center. ...
متن کاملKinetic energy efficiency of single ventricle and TCPC using 4D flow MRI
Background Altered hemodynamics in total cavopulmonary connection (TCPC), a palliation of single ventricle defects, results in long-term complications, such as decreased exercise capacity, arrhythmia, and ventricular failure [1]. Non-invasive hemodynamic evaluation of TCPC has been an important clinical challenge. Several studies have tried to understand and predict specific flow features using...
متن کاملThe effect of Bosentan on exercise capacity in Fontan patients; rationale and design for the TEMPO study
BACKGROUND Palliative treatment with the Fontan procedure has greatly improved survival for children with functionally univentricular heart. Since Fontan performed the first successful operation, the procedure has evolved and is now performed as Total Cavo-Pulmonary Connection (TCPC).An increasing prevalence and longer life expectancy of TCPC patients have raised new challenges. The survivors a...
