The choice of guiding catheter for optimal back-up support is critical in order to achieve a successful PCI. Diagnostic 6 French (F) catheters have an internal lumen diameter as large as 5F guiding catheters.

32 coronary stents were implanted using 6F diagnostic catheters in 27 eligible patients at the Montreal Heart Institute. The inclusion criteria were TIMI angiographic score
