Key result
6F guiding catheters match 7F success rates while reducing procedural blood loss.

May support 6F catheter preference to limit blood loss; leaves open randomized confirmation of noninferiority.

Does percutaneous transluminal coronary angioplasty using a 6F guiding catheter maintain procedural success and reduce blood loss compared to a 7F guiding catheter in patients undergoing coronary angioplasty?
Absolute Event Rate: 94% vs 97.1%
Using a 6F guiding catheter for coronary angioplasty is feasible, with success rates comparable to 7F catheters, and significantly reduces procedural blood loss.
Resar et al. (1994) conducted an observational in Coronary lesions requiring angioplasty (n=140). 6F guiding catheter with over-the-wire balloon systems vs. 7F guiding catheters was evaluated on Procedural success in patients. Coronary angioplasty using a new 6F guiding catheter achieved similar patient success rates to 7F catheters (94.0% vs 97.1%) and significantly reduced procedural blood loss (P<0.001).
