Presentation Outline Undisputed current facts PCI improves access to revascularisation Availability
Access to Revascularisation - Availability Existing immediate capacity Dominant method for revascularisation UK PCI growth rate - 16% per annum UK CABG growth rate - static or negative Revascularisation event ratio trend > 2 : 1 Immediate ability to grow capacity favours PCI NSF targets - and beyond New indications
UK Activity: PCI v Isolated CABG
Presentation Outline Undisputed current facts PCI improves access to revascularisation Availability Patients with co-morbidity Patients with acute presentations Acute coronary syndromes Primary PCI for ST MI Cardiogenic shock
Improved Cardiac Provision Favours PCI Better primary prevention Earlier investigation and treatment of CAD Aggressive early approach to occlusion Primary PCI for AMI Early PCI for non-ST elevation ACS Reduced incidence of Advanced ‘surgical’ disease’

PCI - Appeal to Patients Experience from consent attempts in RCTs Shorter hospital stay
SoS Trial: Length of Stay - Index Procedure Median 3 daysMedian 10 days
PCI - Appeal to Patients Experience from consent attempts in RCTs Shorter hospital stay Reduced immediate procedural morbidity Avoids GA, scars etc Rapid rehabilitation CABG option remains (short or long term)

Presentation Outline Undisputed current facts Historic trials favour CABG Reduced repeat revascularisation
SoS Trial: Repeat Revascularisation Hazard ratio 3.90 (2.58 to 5.91)
SoS Trial: Death or Non-Fatal Q Wave MI Hazard ratio 0.95 (0.63 to 1.43)
Mortality to 1 Year
Presentation Outline Undisputed current facts Historic trials favour CABG Reduced repeat revascularisation Emerging clinical data - favours PCI
PCI v CABG: The Current Picture Non - MACCE adverse events SoS data Hospitalisation events after index revasc Non - MACCE : Never reported CABG 351 (0.7 per patient) PCI 156 (0.3 per patient) MACCE: PCI - superior safety and efficacy
Latest Trials From TCT 2004 ARTS 2 Registry n = 607 MV revasc by DES More diabetes than ARTS 1 (26% v 18%) More 3 VD (54% v 28%) More stents (3.7 [73mm] v 2.8 [48mm]) 6 month freedom from MACCE ARTS % ARTS 1: PCI % CABG %
ARTS II - MACCE Free Survival
