Coronary Artery Assessement by TEE in Congenital Heart Disease

Status Completed

Clinical Trial Summary

This study aims to establish normal coronary artery pulse Doppler flow patterns and velocities using transoesophageal echocardiography (TEE) in patients with a variety of congenital heart disease. This will be accomplished by performing pre-operative and intra-operative TEEs on up to 250 patients undergoing surgery for congenital heart disease.

Clinical Trial Description

Little is known about coronary artery flow patterns in children. Invasive and non invasive studies in normal children have demonstrated that coronary artery flow velocities decrease with age and therefore heart rate. 'Normal' flow velocities in the left coronary artery are usually accepted between 0.3-0.6m/sec depending on age of the patient. Less is known about coronary flow patterns and velocities in patients with congenital heart disease. In addition the effects of coronary artery bypass and altered loading conditions may affect coronary flow patterns and velocities and in theory alter short and long term outcomes. This study hopes to is to establish normal coronary artery pulse Doppler flow patterns and velocities using transoesophageal echocardiography (TEE) in patients with a variety of congenital heart disease. ;
