“…In order to reduce these and improve patient comfort, efforts have been made to reduce progressively the size of cardiac catheters. Earlier studies [5][6][7]12] with 4 and 5 Fr catheters found angiographic quality to be reduced and noted technical problems relating to contrast injection and catheter displacement from the coronary ostia during injection. A study of 4 Fr catheters used from the brachial route [13] also found angiographic quality to be inferior with 4 Fr catheters, with the most marked differences noted in opacification of the LAD.…”

“…Local vascular complications remain the most frequent complication of coronary angiography (0.43%-0.6% of cases) [3] and are more common with larger-size femoral punctures [4]. Early work [5][6][7] with smaller diameter catheters was not encouraging. Despite achieving ambulation at a mean of 2.6 hr, the operators criticized catheter handling and the quality of angiographic images obtained [8].…”

The aim of this study was to assess the quality of angiograms obtained using 4 Fr catheters compared with 6 Fr catheters, the ease of use of the 4 Fr catheters, and the safety of patient mobilization 1 hr following 4 Fr angiography. Details of catheter performance and procedural details were recorded at the time of the angiogram. The angiographic images were scored on the quality and completeness of vessel opacification throughout systole and diastole. A total of 410 patients were recruited. There was no difference between 4 and 6 Fr for procedural variables. All angiograms were considered to be of diagnostic quality. The angiographic scores for the right coronary artery and left ventricular injections were no different between 4 and 6 Fr. However, the angiographic scores for the left anterior descending and circumflex arteries were lower with 4 than with 6 Fr (both P < 0.05). Patients who had 4 Fr angiography mobilized safely at 1 hr and reported significantly less discomfort and bruising than 6 Fr patients. Good-quality diagnostic coronary angiograms can be achieved using 4 Fr catheters with the advantage of earlier postprocedural mobilization and reduced discomfort and bruising for the patient.

“…If similar results could be obtained with smaller 5 or 6 French catheters, patient acceptance of the follow-up catheterization required for coronary artery disease intervention studies could be optimized. Limited data suggest that this may not be possible with 5 French catheters [11][12][13][14]. In this study, 20 mild to moderately severe stenoses from 15 patients enrolled prospectively were sequentially interrogated using standard 8 French catheter techniques and 6 French catheters using hand and power injection, and cine acquisition.…”

To determine the suitability of 6 French catheters for quantitative coronary arteriography, the relative accuracy and reproducibility of one type of these catheters was compared to that obtained with standard 8 French catheters in 20 stenoses. Duplicate injections with polyurethane 6 French catheters were obtained using hand and power injection technique with cineangiographic acquisition (four 6 French catheter injections total per stenosis). Measurements of both percent diameter stenosis and absolute dimensions were compared to those obtained with hand injection and cine acquisition using 8 French catheters as a "gold standard." While the reproducibility of dimension determination with the 6 French catheter was generally similar to that obtained with the 8 French catheter (0.27 +/- 0.23 mm for absolute diameter and 8.1 +/- 7.4% for percent diameter stenosis), accuracy was significantly less for the 6 French catheter for measurement of absolute dimensions. Thus, while apparently well suited for serial measurements of the same stenoses, 6 French catheters may not be as accurate in the determination of absolute artery dimensions as 8 French catheters.

“…This was looked at by Molajo et al [7], who compared the performance of the 8F catheter and the new "superflow" 5F (Cordis) catheter, which has a larger luminal diameter than the normal 5F. They observed that, although there was no significant difference in the bleeding complications between the two catheters, the fluoroscopic time was significantly more with the 5F and this was also associated with poor torque and general image quality.…”

The functional efficacy of a conventional 7F (high flow) coronary catheter (hand injection) was compared with a 5F (high flow) catheter using hand and powered injection in 29 patients with ischemic heart disease. Patients were randomized to 5F or 7F catheters as the initial catheter. Consecutive comparative coronary angiograms were performed in the 15 degrees right anterior oblique (RAO) view using Judkin's technique. Visual diagnostic grade (Grade 1 = Diagnostic, Grade 2 = Equivocal, Grade 3 = Nondiagnostic), vessel filling, vessel density (using a densitometer and corrected for background), streaming, and dislodgement were all evaluated independently by two experienced angiographers with correlation of results. Mean diagnostic grade (1.31 +/- 0.48) was significantly better with the 7F compared to 5F (hand) 1.72 +/- 0.81 and 5F (power) 2.00 +/- 0.71 (P less than or equal to 0.05) for each. Streaming was seen in 55% of injections with 5F (hand) versus 88.5% with 5F (power) and 20.7% with 7F. Measured vessel density was not different for the two catheters. Coronary injection dislodgement occurred significantly more often with 5F power injections than with hand injection of either catheter. Finally, in 6 (30%) of 20 patients in which the 5F was randomly the second catheter used, the operator had to revert to the 7F catheter in order to obtain adequate images. In conclusion, angiographic quality is reduced with 5F catheters compared to 7F high flow in certain patients. Thus, to achieve optimal diagnostic angiograms, larger lumen catheters may be required during certain procedures initially begun with 5F catheters.
