·  B66 (2005) - family history of sudden unexplained death

·  B128 (2008) - chest pain with exercise

Group B patients s/p anomalous left coronary artery from the pulmonary artery repair:

·  B148 (2010) test - no clinical action taken on patient

·  B149 (2010) test - no clinical action taken on patient

Group B patients with right coronary artery abnormalities:

·  Patient B18 false positive (see text in paper) anomalous RCA from LCA

·  One patient, B125 (2008), presented with a heart murmur. Echo was suspicious for an anomalous RCA from the left and was confirmed by CT angiogram. At surgery, the RCA had an intramural course from the LCA and was unroofed. The patient did not have ischemia on the postoperative exercise test (myocardial perfusion test was not done postoperatively)

·  Patient B143 (2009) anomalous RCA from LCA suspected by echo and confirmed by CT. Both preoperative and postoperative ETT with MPI were negative.

·  Patient B150 (2010) anomalous RCA from the LCA suspected by echo and confirmed by MRI. He underwent preoperative and post operative MPI were negative.

·  Patient, B10 (2005), had a coil in the right coronary artery that drained to the right ventricle. There were no ECG changes of ischemia during the ETT. The LVEF was 65%, but there was dyssynergy of the septum and inferior walls which led to a positive test.

·  One patient (B137) presented at 8 years old with a family history of dilated cardiomyopathy in the father. Echocardiogram suggested the RCA originating from the LCA. MRI confirmed finding with RCA passing posterior to aorta (and not in between the great arteries). At age 8 y/o due to chest pain during exercise, the patient had a MPI which was normal.
