Figure 1. Transcatheter closure of LAD fistula using Guglielmi detachable coil in a patient with no symptoms. (A): Before coiling; (B): After 2 GDCs deployment, there was still insignificant flow in the fistula; (C): Four months after coiling. The flow from another fistula (from LCX, white arrow) was seen, but the fistula originated from LAD was totally occluded. The distal LAD became larger (black arrow) due to lack of stealing phenomenon. (D): LAO cranial position, the fistula originated from LAD was clearly seen and was totally occluded. GDCs: Guglielmi detachable coil; LCX: left circumflex; LAD: left anterior descending; LAO: left anterior oblique.
