Interventional Management

Procedural Step

PCI +  LM  , LAD +   LCX   (if fail LCX   sacrifice of LCX  )heavy calcified  :   Arthrectomy ?    Yes   (but see from IVUS data )                   Temporary pacemaker  Hemodyanamic support ?    Low LVEF + CHF                    only   IABP  available
 RFA  . 7F EBU 3.5 side hole GD
 IABP via LFA , Temp pace vis LFV     for hemodynamic supported 
Predilated with  small balloon 2.0 x15
exchange  to  rota floppy  Rotablator  1.5 burr 180,000 rpm x 3 run , follow by NSE  alpha scoring balloon  3.0 x 13 @ 14atm 
Try  to open LCX ,Pilot 50 +  Finecross failed  Pilot 200 +   Crusade type R double lumen MC  Injection  from  MC ,Seqential dilated with  
Balloon  SC  1.5 x 15  ,Balloon   SC 2.0 x 15  ,Balloon   NC  2.5 x 15 
Stent mid LAD ZES 3.0 x 18  overlapped position  with ZES 3.5 x 24
Position LCX stent and deployed mini crush technique .position LCX stent  with
ZES 3.0 x 14  with Guidezilla  guide extension 
Mini crush  with LM-LAD stent  , rewire and kissing 
POT NC with NC 4.0 x 8  and final angiogram

Case Summary


 contrast 100  ml 
 80 minutes procedure time 
 off IABP  6  hr  after  PCI 
Off  ET tube  24 hr  later 
 D/C   3 days after PCI 
  Improve symptoms  , No cheat pain 
  Follow up regular  at CHF clinic   without   readmission    
     for  6  months
    Improve  LVEF  to 42  % 

PCI with LM bifurcation + CTO ostial LCX  is very complex  in high risk patient
