“Safety and Effectiveness of Intracoronary Imaging-Guided Percutaneous Coronary Intervention in Contemporary Practice: Insights from BMC2” is in print in Circulation Cardiovascular Interventions. 

Using larger balloon/stent diameters and longer stents during PCI procedures is thought to reduce the likelihood of in-stent restenosis. This is a re-narrowing of the arteries after a PCI procedure that is typically caused by scar tissue forming. University of Michigan Medical School student, Thomas Basala, BS, and his mentor, Devraj Sukul, MD, MSc, FACC, FSCAI utilized BMC2 data to evaluate if real-world intracoronary imaging-guided PCI results in the use of larger balloon/stent diameters and longer stents, having the potential to improve patient outcomes.  

The authors reviewed Consortium data for PCI performed on previously untreated coronary artery lesions - abnormal changes in the coronary arteries that impair blood flow to the heart -between July 2019 and June 2022. 

Intracoronary imaging utilization during the data timeframe increased from 11.2% to 32.1% and was associated with a +0.16 mm increase in stent diameter, +0.31 mm increase in maximum balloon diameter, and a +1.73 mm increase in total stent length. 

In July 2019, 11.2% of PCIs were performed with intracoronary imaging. That number increased to 32.1% by June of 2022. There was a +0.16 mm increase in stent diameter, a +0.31 mm increase in maximum balloon diameter, and a +1.73% mm increase in total stent length.

There was no significant increase in the rate of complications despite increases in intracoronary imaging use and stent/balloon sizes during the study period.  

Further research is needed to evaluate the association between intracoronary imaging use and procedural complications.
