Parasternal short axis view on echocardiography shows that (arrow) the LMCA seems to arise from the AO in the normal fashion. (AO = aorta; LAD = left anterior descending artery; LMCA = left main coronary artery; PA = pulmonary artery.)

3. Fig 2
(A) Color Doppler showing retrograde flows in LAD and LCX. Note the blue flow in LAD (normal flow is red). (B) Color Doppler showing apparently normal flows in LAD and LCX. This pattern of flow was seen when there was significant acidosis and hypercarbia. (AO = aorta; LAD = left anterior descending artery; LCX = left circumflex artery; PA = pulmonary artery.)

4. Fig 3
(A) 12 lead ECG showing ST depression and T wave inversion in V1 to V6. ST elevation is also obvious in inferior leads. (B) ST depression and T wave inversion is seen to be normalized. This was consistently observed during periods of respiratory acidosis. This ECG was taken when echocardiography showed antegrade flows in LCA. (ECG = electrocardiogram; LCA = left coronary artery; ST = segment elevations.)
