Contrast echocardiography in the diagnosis of anomalous left coronary artery arising from the pulmonary artery

Summary We have demonstrated an anomalous left coronary artery originating from the main pulmonary artery by saline contrast echocardiography. The anomalous vessel was easily identified using contrast injections into the ascending aorta at catheterization and into a radial artery cannula following catheterization. Contrast echocardiography may be useful in the diagnosis of this lesion when two-dimensional and Doppler echocardiography fail to show the anomalous vessel.
