Insights
This case report details complex percutaneous coronary intervention (PCI) challenges in a right coronary artery (RCA) with severe calcification. It highlights troubleshooting techniques for stent deployment and wire management during complex PCI.
Area of Science:
- Interventional Cardiology
- Cardiovascular Surgery
- Medical Device Technology
Background:
- A 73-year-old male with a history of coronary artery bypass grafting (CABG) presented with a calcified lesion in the right coronary artery (RCA).
- Percutaneous coronary intervention (PCI) was planned for the complex lesion.
- Previous CABG surgery can influence subsequent PCI strategies and outcomes.
Observation:
- Initial attempts at stent implantation in the distal RCA using a child catheter resulted in device entrapment and stretching.
- Difficulty in deploying a second stent in the mid-RCA due to severe calcification.
- Accidental dislodgement of a stent from its balloon during attempted withdrawal.
- Fracture of a guidewire tip during stent removal, requiring retrieval with a gooseneck snare.
Findings:
- Successful stent implantation in the distal RCA after managing the entrapped child catheter.
- Overcoming severe calcification in the mid-RCA using the buddy wire technique.
- Managing stent dislodgement and guidewire fracture during the procedure.
- Ultimately achieving successful stent placement in the mid and proximal RCA using the balloon anchor technique.
Implications:
- Demonstrates the technical challenges and potential complications associated with complex PCI in heavily calcified coronary arteries.
- Highlights the importance of advanced techniques and device manipulation for successful outcomes in challenging cases.
- Provides insights into troubleshooting strategies for device entrapment, stent dislodgement, and guidewire issues during coronary interventions.
Abstract:
A 73 year-old male who underwent coronary artery bypass surgery (CABG) 8 years ago had PCI performed on him for a diffuse calcified stenotic lesion in the right coronary artery (RCA). Following 2.5 mm non-compliant balloon dilatation supported with a child catheter (Dio from Goodman), we implanted a stent to the distal RCA through this catheter. However, because the tip of Dio was trapped by the implanted stent, it was stretched and almost ruptured by pulling it. Next, we tried to implant a stent for mid RCA with buddy wire technique, but we could not deploy it because of calcification. When we tried to withdraw this stent system, the stent was accidentally dislodged from the balloon. We could withdraw the stent with twisting two wires. However, because one of these wires had crossed a small artery in the distal RCA at twisting, a tip of this wire was fractured when the stent was removed. We could remove this wire with gooseneck snare. Finally, we successfully implanted stents in the mid RCA with balloon anchor technique and to the proximal RCA.

Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...
