Clinical Information

Patient initials or Identifier Number

2003166

Relevant Clinical History and Physical Exam

Chest tightness and dyspnea on exertion recentlyHistory : Hypertension and hyperlipidemia without regular medicationsECG : Sinus rhythm and atrial premature contractionPhysical exam:No basal ralesNo peripheral edema

Relevant Test Results Prior to Catheterization

Tl-201 myocardial perfusion scan : Myocardial ischemia over 55% LCX territory in pharmacologic stress

Relevant Catheterization Findings

LMCA :  - M/3 : Tubular stenosis, max 70-80 % ; Medina (1,1,1)LAD :  Luminal irregularity (LI)- P/3 : Segmental stenosis, max 80 %- M/3 : Segmental stenosis, max 80 %LCx : LI, severe calcification, and tortuous vessel- P/3: Segmental stenosis, max 90 %- M/3 : Chronic total occlusion (CTO)- Ostium of OM1 : CTORCA :  LI and calcification- P/3 to D/3 : Diffuse stenosis, max 90 %- Ostium to P/3 of PL : Segmental stenosis, max 90 %- P/3 to M/3 of PDA : Tubular stenosis, max 80 % 


Interventional Management

Procedural Step

1st CAG
1. Balloon dilation and stent implantation over os-RCA to p-PL.
2nd CAG
1. SION wire was advanced to d-LAD and SION blue wire was advanced to m-LCX before CTO lesion.
2. Balloon dilation over m-LM to m-LAD and m-LM to m-LCX.
3. Corsair microcatheter was along SION Blue wire to m-LCX.
4. Antegrade approach with XTR wire was successfully penetrated the CTO cap over m-LCX after wire escalation, and the XTR wire was advanced to d-LCX, which
was confirmed at true lumen by angiography from RCA ostium
5. Balloon dilation and stent implantation from LM to LAD & LCX were performed. No residual stenosis or thrombus, also with no other complication.



Case Summary

1. CTO PCI by using ¡° Hybrid Approach¡± appears efficient.2. Good angiography by dual injections is fundamental for CTO PCI.3. CTO lesion characteristics non-ambiguous proximal cap suitable for antegrade approach should be clarified.4. Changes in crossing strategy are based on angiographic characteristics of the CTO.
