ALCAPA Presents in an Adult with Exercise Intolerance but Preserved Cardiac Function
Figure 1
Coronary angiogram showing ALCAPA with left-to-right shunt. Retrograde filling was seen through collaterals arising from the enlarged right coronary artery (RCA), which gives rise to collaterals to a large left anterior descending artery (LAD) and left main artery (LMA) originated from the left main pulmonary (LP) trunk. The LAD and LMA are filling the pulmonary artery through a pronounced left-to-right shunt.
