Drug-coated balloon in primary PCI for stemi

Background

 Primary percutaneous coronary intervention

(PPCI) is the preferred reperfusion therapy for ST

elevation myocardial infarction (STEMI)

 Associated with higher reperfusion rates (vs lytic)

 ↓ rates of reinfarction, CVA and death

 Started with primary angioplasty (POBA)

Associated with abrupt closure, recurrent ischaemia ; occlusion and

restenosis at 6 mths

DRUG-COATED BALLOON 
IN PRIMARY PCI FOR STEMI 
 Ho Hee Hwa 
 Background 
 Primary percutaneous coronary intervention 
(PPCI) is the preferred reperfusion therapy for ST 
elevation myocardial infarction (STEMI) 
 Associated with higher reperfusion rates (vs lytic) 
 ↓ rates of reinfarction, CVA and death 
 Started with primary angioplasty (POBA) 
 Associated with abrupt closure, recurrent ischaemia ; occlusion and 
restenosis at 6 mths 
 PAMI-STENT(1999) 
Routine implantation of bare metal stents associated with ↓ TVR 
 6 mth mortality rate was similar

 6 mth mortality rate was similar 
Use of DES in PPCI for STEMI 
 Trials evaluating use of DES in AMI 
(Typhoon, Passion, Sesami,etc) 
 Meta-analysis of 7 trials: similar mortality 
benefit compared to BMS but ↓TLR in DES 
 Recent trial : Comfortable AMI (risk of MACE 
at 1 year lower with the biodegradable 
polymer BioMatrix stent

 Primary PCI in STEMI 
 Is it feasible to use DEB during PPCI? 
Issues with DEB in PPCI 
 Is DEB effective in a thrombus-laden 
artery? 
 Can pt tolerate prolonged balloon 
inflation? 
 Are we willing to accept a less than perfect 
result? 
 DEB in STEMI 
 DEB-AMI (drug eluting balloon in acute ST-segment 
elevation myocardial infarction) trial: a multicenter 
randomized comparison of DEB + BMS versus BMS 
versus DES in PPCI with 6-month angiographic, 
intravascular, functional, and clinical outcomes. 
 In STEMI patients, DEB + BMS implantation failed to show 
angiographic superiority to BMS only. 
 Angiographic results of DES were superior to both BMS and 
DEB.

3 Uses of DEB in PPCI 
 POBA of de novo lesion 
 POBA of late/very late stent thrombosis 
 Adjunctive therapy for diffuse lesion 
 DEB for very late ST 
Avoid stent-in stent approach 
 DEB as adjunctive therapy 
DEB 3.0 x 20 
Avoid excessive metal 
Stent thrombosis in STEMI 
 Horizons-AMI - Stent thrombosis ~ 3.5% 
 Comfortable-AMI 
 - 0.9% (BES) ; 2.1% (BMS) at 1 year 
 - 1.4 % (BES) ; 2.6 % (BMS) at 2 years 
 ST Rate ~ 1 to 3.5%

 Conclusion 
 Use of DEB in PPCI for STEMI ( as primary 
therapy/adjunctive therapy) is feasible in 
selected grp of pts 
 Can be used in de novo, VLST and 
adjunctive therapy 
 Careful patient selection 
Tips and tricks in using DEB 
in PPCI 
 PCI approach: aspirate >> predilate >> DEB 
 Gp2b/3a inhibitors 
 Know how to grade dissection
