Background: The J-CTO investigators recently developed angiographic difficulty scores for each of the three major coronary arteries in patients undergoing first-attempt chronic total occlusion (CTO) percutaneous coronary intervention (PCI) in de novo occlusions.
Methods: We examined the performance of the individual J-CTO scores in a large multicenter registry.
Results: The CTO lesion location was as follows: right coronary artery (RCA) 3,805 (54%), left anterior descending artery (LAD) 2,303 (33%), and left circumflex (LCX) 935 (13%).
Article Synopsis
- Exercise stress testing (EST) is frequently used to assess chest pain, often aiming for 85% of the age-predicted maximum heart rate (APMHR), calculated with the formula 220 minus age.
- The reliability of this formula and the 85% target has been questioned, as not reaching this threshold (chronotropic insufficiency) could indicate a higher cardiovascular risk.
- Alternative metrics like percentage heart rate reserve (%HRR), maximum rate pressure product (MRPP), and maximum metabolic equivalent of tasks (METs) may provide better predictions for cardiovascular health than solely focusing on the 85% APMHR.

Article Synopsis
- Plaque modification microcatheters (PM), specifically Tornus and Turnpike Gold, are specialized devices used to treat chronic total occlusion (CTO) in coronary artery interventions.
- In a study analyzing their use across multiple centers, PMs were employed in 242 cases, representing only 1.6% of total procedures, with usage declining over time.
- The results showed that both types of microcatheters had similar success rates and complication levels, indicating that while they are seldom used, they are effective and safe in CTO interventions.
