Success Rates of Percutaneous Coronary Intervention to Chronic Total Occlusions Continues to Improve After the Adoption of a CTO-PCI Programme in Standalone PCI Centres - a Single Centre Canadian Experience

While non emergent percutaneous coronary intervention (PCI) can be safely and effectively be carried out in high volume stand alone centres, there is limited data examining the feasibility of performing PCI to chronic total occlusions (CTO-PCI) because of the relatively high CTO-PCI failure rates. With the development of retrograde and contemporary anterograde approaches the success rates of CTO PCI continues to improve. The CK Hui Heart Centre at the Royal Alexandra Hospital has been performing PCI without on site surgery over the last 30 years. We identified all patients undergoing CTO PCI between January 2010 and March 2013 and examined the outcomes of CTO-PCI procedures over 4 separate time frames: Jan 2010 - Dec 2010, Jan 2011-Dec 2011, Jan 2012 - Dec 2012 and Jan 2013 - Apr 2013.
