MRI Heart Function with Stress There is no relevant literature to support the use of MRI heart function with stress in the evaluation of known single ventricle physiology. Radiography Chest Other than evaluation of device or stent positioning, there is no relevant literature to support the use of radiography chest in the evaluation of known single ventricle physiology. SPECT or SPECT/CT MPI Rest and Stress There is no relevant literature to support the use of SPECT or SPECT/CT MPI rest and stress in the evaluation of known single ventricle physiology. FDG-PET/CT Heart There is no relevant literature to support the use of FDG-PET/CT heart in the evaluation of known single ventricle physiology. US Echocardiography Transesophageal TEE may provide useful information before, during, or after surgery for stage 3 palliation regarding pulmonary arterial or pulmonary venous flow patterns, severity of atrioventricular valve regurgitation, atrial shunt, and cardiac thrombus. Variant 7: Child or adult. Known single ventricle physiology. Postoperative evaluation after stage 3 single inadequate assessment of ventricle palliation (total cavopulmonary connection). Incomplete or cardiovascular morphology and function after transthoracic echocardiography. Next imaging study. Stage 3 repair for single ventricle palliation involves baffling of all systemic venous drainage directly to the pulmonary arteries, known as total cavopulmonary connection or Fontan operation. This is typically performed between 2 to 4 years of age and most commonly consists of either a lateral tunnel intracardiac baffle or an extracardiac conduit, with or without a fenestration. The Fontan operation also ensures that hepatic blood flow is directed into the lungs via the pulmonary arteries, thus preventing the formation of pulmonary arteriovenous malformations. Today, the estimates of 20-year survival for survivors of the Fontan procedure vary between 61% and 85% [51].
