Introduction
• Drug-eluting stents have defined a new era in the successful treatment of coronary artery disease
• However, like any therapy, DES results are not always what are predicted or expected, stent placement alone does not guarantee the best outcome
• Unless the stent is optimally deployed with full lesion coverage, full expansion and good apposition to the vessel wall, there remains a risk of complications such as late stent thrombosis
3
Introduction
• Such complications can compromise the benefits of the intervention and add to the cost of treatment
• Lesion preparation in general and pre-dilatation in particular can optimize stent deployment to better achieve the full benefits of DES therapy
• Optimal deployment assurance is vital to ensure good stent apposition and uniform absorption of the drug within the treated lesion
Pre-dilatation may help reduce stent malapposition & late stent thrombosis

Powerline™ PTCA Dilatation catheterMessaging
Messaging:
• The Powerline™ PTCA dilatation catheter is a high performance pre-dilatation workhorse balloon catheter designed to prepare the lesion for optimal DES placement, even in complex anatomy
• Powerline’s advanced catheter technology offers the right balance of PUSH, TRACK and CROSS to ensure optimal balloon placement and expansion
Take the fast track to superior patient outcomes

Importance of pre-dilatation
Pre-dilatation is not a matter of evidence based medicine
What clinical data tells us:
• Previous studies reveal that direct stenting, as compared to pre-dilatation, has similar feasibility, efficacy and safety outcomes
• However, most of these studies have been performed only in the pre-DES era and in very selected patients with non-complex lesions
• Today >50% of case involve B2/C lesions
• On the other hand, pre-dilatation reduces costs, fluoroscopic exposure, procedural time and contrast use
• Not evidence based medicine, but experience and current practice have a real value

Importance of pre-dilatation
Main risks of direct stenting:
• Inability to dilate the stent in heavily calcified or fibrotic lesions, which may lead to serious complications, i.e. surgery
• Incomplete stent deployment
• In-accurate stent placement
• Loss of guidewire and/or guiding catheter engagement due to insufficient support
• Stent shift due to watermelon seeding
• Stent dislodgement
• DES polymer damage

Stent malapposition is a main predictor of late stent thrombosis

Importance of pre-dilatation
• Pre-dilatation optimizes stent outcomes and may
• Assure optimal stent placement
• Identify un-dilatable lesions prior to stenting, hence avoiding serious complications
• Create a pathway for the stent
• Provide understanding of lesion length, diameter, and morphology
• Help to avoid complications with potential stent gaps or geographic misses
• Prevent damage to the drug coating during delivery
• Reduce plaque shift
• Reduce need for high pressure stent implantation
• Preserve sidebranches in bifurcations
• Reduce economic risk of improper DES selection
Pre-dilatation may reduce stent malapposition & late stent thrombosis
