Insights
Using larger guiding catheters (7-F and 8-F) for percutaneous coronary intervention (PCI) increases risks of complications like kidney injury and bleeding compared to 6-F catheters. Smaller guide catheters may improve patient outcomes in PCI procedures.
Area of Science:
- Cardiovascular Interventions
- Interventional Cardiology
- Medical Device Safety
Background:
- The relationship between guiding catheter size and percutaneous coronary intervention (PCI) complications is debated.
- Contemporary PCI practices involve various guiding catheter sizes.
Purpose of the Study:
- To evaluate the association between guiding catheter size and complications during percutaneous coronary intervention (PCI).
Main Methods:
- A retrospective analysis of 103,070 patients undergoing PCI using 6-F, 7-F, or 8-F guide catheters.
- Comparison of procedure and outcome variables across different guiding catheter sizes.
Main Results:
- Larger guiding catheters (7-F and 8-F) were linked to increased contrast use and post-PCI complications.
- Significant associations were found between larger guides and contrast-induced nephropathy, vascular complications, bleeding, and transfusion needs.
- 8-F guides, but not 7-F, showed increased risks for major adverse cardiac events and in-hospital mortality.
Conclusions:
- PCI with 7-F and 8-F guiding catheters is associated with higher rates of contrast use, renal complications, bleeding, and transfusion requirements compared to 6-F guides.
- 8-F guides are specifically linked to increased nephropathy requiring dialysis, major adverse cardiac events, and mortality.
- Selecting smaller guiding catheters may lead to better clinical outcomes in patients undergoing PCI.
Objectives:
We evaluated the association between guiding catheter size and complications of percutaneous coronary intervention (PCI).
Background:
The association between guiding catheter size and complications of PCI in contemporary practice remains controversial.
Methods:
Procedure and outcome variables from 103,070 consecutive patients that underwent PCI with 6-F (n = 64,335), 7-F (n = 32,676), and 8-F (n = 6,059) guide catheters were compared.
Results:
Compared with 6-F guides, PCIs performed with 7- and 8-F guides were associated with incrementally more contrast agent use, and more post-PCI complications including contrast-induced nephropathy, vascular access site complications, bleeding, transfusion, major adverse cardiac event, and death. After multivariate analysis, the use of larger guides were associated with a higher risk of contrast-induced nephropathy (7-F odds ratio [OR]: 1.18, p = 0.0004; 8-F OR: 1.44, p < 0.0001), vascular complications (7-F OR: 1.19, p = 0.0002, 8-F OR: 1.68, p < 0.0001), decline in hemoglobin >3 g/dl (7-F OR: 1.12, p < 0.0001, 8-F OR: 1.72, p < 0.0001), and post-procedure blood transfusion (7-F OR: 1.08, p = 0.03; 8-F OR: 1.80, p < 0.0001), whereas major adverse cardiac events (7-F OR: 1.06, p = 0.13; 8-F OR: 1.37, p < 0.0001) and in-hospital mortality (7-F OR: 1.11, p = 0.13; 8-F OR: 1.34, p = 0.03) were increased with 8-F but not 7-F guides.
Conclusions:
Compared with 6-F guides, PCIs performed with 7- and 8-F guides were associated with more contrast medium use, renal complications, bleeding, vascular access site complications, greater need for post-procedure transfusion, and 8-F guides with increased nephropathy requiring dialysis, in-hospital major adverse cardiac events, and mortality. These data suggest that selection of smaller guide catheters may result in improved clinical outcome in patients undergoing contemporary PCI.
