Figure 7. Selection of cardiovascular imaging method and stress protocol for pediatric patients with congenital heart disease and suspected ischemia. 987 Examples of causes of dynamic obstruction: anomalous coronary arteries, stent compression, myocardial bridging, vasospasm. Examples of causes of fixed obstruction: atherosclerotic coronary obstruction, surgical narrowing of the coronary ostia, thickening of the intima. Examples of causes of microvascular dysfunction: surgical manipulation of the coronary arteries in arterial switch surgery, familial hypercholesterolemia, systemic lupus erythematosus. Stress echo: stress echocardiography; CMR: cardiac magnetic resonance; PET: positron emission tomography; SPECT: single photon emission computed tomography; N-13: 13 N ammonia; Rb-82: 82 rubidium; Tc-99m:99mtechnetium; Gd: gadolinium. *Cardiovascular imaging methods presented sequentially according to the choice of stressor. **Available in Brazil only for research purposes. ***Not currently available in Brazil.
