A brand new evaluation of PROGRESS-CTO (PROspective World REgiStry for the Examine of Continual Complete Occlusion Intervention; www.progresscto.org), a global multi-center registry of continual whole occlusion (CTO) percutaneous coronary intervention (PCI), was introduced at present as late-breaking scientific analysis on the Society for Cardiovascular Angiography & Interventions (SCAI) 2022 Scientific Classes. The findings present a rise within the success and effectivity of CTO PCI with out a rise in main antagonistic cardiac occasions (MACE).
Coronary coronary heart illness, a kind of coronary heart illness the place the guts can not ship sufficient oxygen-rich blood to the guts, is the main explanation for demise in the USA (NIH). CTO, or full blockages of the coronary arteries, is reported in roughly 30% of coronary coronary heart illness sufferers. PCI is a minimally invasive process used to deal with narrowing of the arteries in CTO sufferers.
CTO PCI is a quickly evolving approach in interventional cardiology to assist deal with sufferers with continual whole occlusion. The PROGRESS-CTO registry affords a possibility to develop our international information on this therapy choice and additional construct on revolutionary strategies.”

Using the PROGRESS-CTO registry, researchers examined the scientific and angiographic traits and procedural outcomes of 10,249 CTO PCIs carried out on 10,019 sufferers at 40 U.S. and non-U.S, facilities between 2012 and 2022.
Findings embrace:
- Low incidence (2.1%) of in-hospital main antagonistic cardiac occasions (MACE) with out important adjustments over time.
- Excessive prevalence of prior PCI (62%), prior coronary artery bypass graft surgical procedure (29%), and diabetes mellitus (43%) amongst registry members.
- Technical success was excessive (86%) and elevated over time, from 81.6% in 2016 to 88.1% in 2021.
- Proper coronary artery (53%), adopted by the left anterior descending artery (26%) and left circumflex artery (19%) have been commonest goal vessels.
- The goal CTOs have been extremely advanced with imply J-CTO rating of two.4 ±1.3 and PROGRESS-CTO rating of 1.3 ±1.0.
Initially, there was a hesitancy in direction of CTO PCI due to considerations of low success and excessive complication charges. Our registry evaluation demonstrates that the other is true – larger success charges mixed with a low danger of antagonistic occasions which may be attributed to elevated operator coaching and real-world expertise.”

“The registry contributes to the information base for CTO PCI operators and offers first-hand insights to assist physicians coaching for CTO PCI, which we hope will finally improve entry to this crucial process for sufferers,” mentioned Bavana V. Rangan, BDS, MPH, Program Director, Heart for Coronary Artery Illness on the Minneapolis Coronary heart Institute Basis.
Researchers notice a necessity for elevated operator coaching with a purpose to higher serve the big variety of sufferers in want of CTO PCI.
