Case Presentation
- A 73-year-old man present with angina like chest pain and dyspnea on exertion, concerning for unstable angina.
- Pertinent medical history were HTN, HLD, CAD s/p CABG x 3 in 2002.
- Medications: Aspirin 81mg , Clopidogrel 75mg, Metoprolol 50mg, Lisinopril 10mg, Atorvastatin 10mg, Furosemide 40mg, Pantoprazole 20mg
- Coronary angiogram showed 3V CAD with patent LIMA to LAD, 95% thrombotic radial graft to D1, and occluded SVG to LCx. LVEF was 30%. Patient had PCI to OM1 and radial graft to D1.
Case Analysis and Planning
STEPS
- Given the presence of a severely tortuous artery, the ideal wire to navigate the lesion should have a soft tip, polymer/hydrophilic cover, or a hybrid type with a hydrophilic body and hydrophobic distal tip.
- We chose Fielder (Asahi) to navigate the tortuous anatomy along with FineCross microcatheter.
- The guide extension catheter was slowly advanced up to mid RCA while the balloon was simultaneously deflated.
- (Balloon assisted suction technique)
Wiring Technique
- Then, three DES were placed in proximal, and mid RCA with an excellent result.
Learning Points
- The optimal wire for tortuous artery should have a soft tip, polymer/hydrophilic cover and we had used Fielder wire in this case.
- A guide extension catheter with a stiff wire (i.e. Grandslam) can be used for a better support and device delivery.
- Another option would be the use of buddy wire technique to deliver the devices in difficult situation. (i.e. Fielder and Runthrough or two Fielder wires)
- In case of difficulty in advancing guide extension catheter, the guideliner suction technique is useful to advance the catheter.
