title: Limitations in the use of five French coronary catheters.
abstract: Five french (5F) catheters are being widely promoted for use in patients undergoing day case angiography including coronary angiography. Although there are theoretical advantages to this practice there are also potential disadvantages. We reviewed various performance parameters of four different brands of 5F coronary catheter and compared them with performance of the six (6F) and eight french (8F) coronary catheters used in routine coronary angiography. All the 5F catheters performed significantly less satisfactorily than the 6F and 8F catheters. 5F coronary catheters cannot be recommended for routine transfemoral coronary angiography.
