With the strong backup force of the 7-Fr JR 3.5 guiding catheter and the buddy wire technique, we attempted to deploy the Promus 3.0 × 23 mm stent. However, the Promus stent was stuck at the proximal edge of the previously placed Cypher 3.0 × 18 mm stent with its proximal half placed in the guiding catheter. There were two guide wires (Marker Pro and Grand Slam) in the right coronary artery.

Schematic presentation of the stuck stent with its delivery system retrieval with a simple balloon technique. A: Before the procedure. The Promus catheter was locked at the proximal edge of the previously placed Cypher stent. B: After the procedure. A 1.3-mm balloon (Lacrosse LAXA 1.3 × 10 mm) was inserted beside the stuck stent through the SION blue guide wire. By dilating this small balloon, the locking point was dislodged and the stuck Promus stent with its delivery system was successfully retrieved into the guiding catheter.

The retrieved Promus 3.0 × 23 mm stent showed a broken strut at its distal tip, but it still maintained a firm connection to the delivery balloon.
