Background: Although there is ongoing progress in coronary artery-bypass graft (CABG) surgery and percutaneous coronary intervention techniques and supplies, the risk of cardiac complications remains high compared with the normal population.
Aim: In this study, our aim was to compare fluoroscopy times in engagement of three different catheters in saphenous vein grafts (SVGs) in post-CABG patients undergoing angiography.
Methods: This was a single-center, cross-sectional, comparative study. We evaluated patients with previous CABG referred for invasive coronary diagnostic angiography. Patients having had SVG–obtuse marginal artery, SVG–diagonal, and SVG–posterior descending artery CABG were included. All patients underwent diagnostic angiography by each of a right diagnostic Judkins catheter, right modified Amplatz catheter, and right guiding Judkins catheter. Demographics and clinical history of patients and fluoroscopy time in different groups were evaluated.
Results: A total of 61 patients were evaluated. The distribution of baseline characteristics in the three groups of our study was normal. Mean fluoroscopy time in SVG–obtuse marginal artery was 25.70±6.70 seconds in group A, 22.23±6.51 seconds in group B, and 17.35±7.82 seconds in group C. Mean total fluoroscopy time was 86.35±16.28 seconds in group A, 73.80±10.00 seconds in group B, and 51.90±10.22 seconds in group C, which was significant (P<0.001).
Conclusion: Our data suggest that when we use the guiding Judkins catheter, fluoroscopy time decreases. However, more evaluations are needed with larger-scale studies and identification of other variables.

This was a single-center, cross-sectional, comparative study based on data collected from medical records and information obtained and recorded. We evaluated all patients with a history of CABG referred for invasive coronary diagnostic or therapeutic procedures between 2015 and 2017 at the Interventional Cardiology Department of Qaem Hospital, Mashhad University of Medical Sciences by one operator. Patients having had all three of SVG–obtuse marginal (OM) artery, SVG–diagonal, and SVG–posterior descending artery (PDA) CABG were included. We excluded patients with existence of tortuosity >45° in the right femoral access site. All patients underwent diagnostic angiography by femoral access with each of a right diagnostic Judkins catheter, right modified Amplatz catheter, and right guiding Judkins catheter.
Subcutaneous infiltration with 15–20 mL 2% lidocaine was done. Then, the femoral artery was punctured under the inguinal ligament with an 18 G needle (using the modified Seldinger method) with insertion of a 6F or 7F sheath. After that, 2,500 IU UFH was prescribed. Hemostasis was achieved with manual hand compression for 2 hours, or in cases of activated clotting <180 seconds. After fluoroscopy-time calculation in diagnostic angiography, percutaneous coronary intervention was performed in patients who needed it.
Outcomes and definitions
The efficacy of the methods studied was assessed by the success rate of the procedure, determined as completion of a coronary angiography and left ventriculography with adequate coronary and graft opacification, or in therapeutic interventions, taking a residual lesion <20%, without the need to alter the access port. The length of the process and fluoroscopy time were calculated from the start of the arterial puncture to the removal of the last catheter. However, we defined fluoroscopy time as time from the exit of 0.035-gauge wire or end of Right coronary artery angiography till the establishment of a catheter in the aorta root. Procedural safety was assessed by the occurrence of vascular adverse events contributing to the puncture site, such as hematoma >5 cm, severe bleeding, pseudoaneurysm, arteriovenous fistula, arterial occlusion, or need to repair vascular surgery.
All data were entered in SPSS version 19.0 and analyzed. Qualitative variables are listed as frequencies and percentages. Quantitative data are indicated as means ± SD. Comparisons between groups were done by c2 or Fisher’s exact test for qualitative variables and Student’s t-test or Mann–Whitney U test for quantitative variables. P<0.05 was considered statistically significant.
Written informed consent from all patients was obtained for participation in the study. This study was done according to Mashhad University of Medical Sciences ethical committee guidelines and approved by the committee.
A total of 61 patients were evaluated. The mean age of patients was 56.96±11.34 (32–80) years. Most were female (31, 50.8%). Table 1 shows the demographic data of patients.

Procedures in cardiological intervention involve high-dose radiation to patients because of the extended use of fluoroscopy, various cine runs, and the difficulty of the procedures.13,14 Innovative catheter designs have been developed to allow diagnostic coronary angiography with a single catheter for both coronary arteries with the aim of reducing vasospasm, radiation dosage, and procedure time. Alternatively, conventional femoral approach catheters are also frequently used for transradial access, eg, Judkins left (JL) for the left coronary artery and Judkins right or Amplatz right I for the right coronary artery.15 Despite the lower estimation of risk of radiation exposure for interventionists, there is growing concern about this issue in cardiac catheterization.16
Long-term, low-dose exposure to radiation in the cardiac catheterization laboratory is related to a limited but not negligibly higher risk of cancers.12 Although there is no definite proof of a link between radiation exposure in the cardiac catheterization lab and higher risk of cancer, there are risk-prediction models in which the risk of cancer is deemed to be increased in lab personnel.12 In the past two decades, radiation-dose exposure for primary operators in cardiac catheterization labs not changed.17 However, advances in recent years in lowering scatter-emitted radiation by fluoroscopy/cine-angiography tools raise expectations of reduced radiation exposure for operators. This can be offset by the increased complexity of different cases that occur in modern cardiac catheterization labs. This problem and an inability to affect radiation dose for operators emphasizes the necessity for new shielding methods for lowering radiation exposure. It has been shown that radiation scatter reduction markedly reduces radiation exposure in both patients and operators during interventional fluoroscopic procedures.18
Catheter choice usually is dependent on such factors as operator experience, training, orientation of ostia, and shape of the aorta. For instance, a large aorta makes it very hard to use a Judkins catheter to reach the vein-graft ostium. Similarly, Amplatz catheters have been used successfully in patients having vein grafts with superior takeoff. Cannulation of grafts on the right side may be dependent on the orientation of the right coronary ostium. Most cases with horizontal takeoff might be cannulated more easily with Judkins right catheters. Some right coronary grafts may have steep takeoff, making Judkins catheter use technically challenging, and may be better served using multipurpose catheters with shallow angulation. Therefore, we consider these factors during procedures. Our results showed that using a right guiding Judkins catheter in post-CABG patients can significantly reduce fluoroscopy time over right diagnostic Judkins and Amplatz catheters in diagnostic angiography. This can help to reduce procedure time and lessen radiation exposure for the patient and operator, lowering the risk of radiation-induced cancer. In this study, we excluded patients who underwent more than one-time try to engagement to the artery, in order to eliminate the confounding factor engagement difficulty. Our study population was limited to these three types of grafts, which was a limitation. This issue was related to the fact that most of our patients had these three types of venous grafts in the center and there were no other venous grafts to be compared. Our results also showed a priority for SVG–OM rather than SVG–diagonal or SVG–PDA grafts. This priority can be due to the anterolateral position of the SVG–OM ostium and higher level of its origin, which allows more time to maneuver and higher probability of engagement. There have been few investigations to compare catheter shape and rate of procedural success for the transfemoral approach in coronary angiography. Vorpahl et al15 demonstrated that fluoroscopy time was significantly less in a Tiger II (2.4±1.5 minutes) than a conventional catheter (3.1±2.5 minutes; P=0.01), a major reason for which was the higher use of supplemental catheters (crossover) in Tiger II. In addition, fluoroscopy times after crossover were significantly greater in the conventional catheter (5.8±0.7, P=0.0001) than the Tiger II (7.6±3.0 minutes, P=0.0001). Fluoroscopy time was very similar between the conventional catheter and the Tiger II without crossover (2.2±1.2 min vs 2.3±1.2 min). In 2006, Kim et al19 made a comparison of the Tiger II and Judkins left catheter by measuring procedure time and fluoroscopy time. They found superiority for right coronary angiographic quality with the Tiger II and a marked benefit in process and fluoroscopy time without difference for left coronary angiographic quality. Overall, fluoroscopy time in the prospective randomized trial of Kim et al was significantly lower in the Tiger II (1.55 minutes) vs conventional catheter (2.3 minutes).19 SVG markers assist the angiographer by pinpointing the ostium of the aorta vein-graft anastomosis and by demonstrating the number of vein-graft ostia that must be cannulated at catheterization, significantly decreasing fluoroscopy time. However, in this study, we routinely used the markers by angiographer and all of the processes were performed in the same way in all three groups.
By reducing fluoroscopy time in our study with the right guiding catheter, the risk of cancer in patients and operators can be lowered. Another benefit is better engagement and lowering manipulation that can lead to lower rate of emboli risk in patients. Also, by lowering fluoroscopy time, the usage of dye will decrease and thus lower the rate of contrast-induced nephropathy. However, assessment of contrast-induced nephropathy in this study was not logical, because we did not have any patient with it.
There are several limitations to our study. The design was based on the existence of previous cases, and this made our study affected by some confounding factors. While during patient engagement, these points were followed, we did not access documented reports for all cases. We plan future studies based on this report and hope to resolve these limitations. In our setting, the three reported vein grafts were the most frequent, and we did not have other venous grafts. The findings from our study are hypothesis-generating and may need further validation by a larger prospective randomized trial.
This study and other similar publications highlight the importance of catheter choice and operator training as key components in successful procedures. Our data suggest that when the guiding Judkins catheter is used, fluoroscopy time will decrease and lead to the benefits mentioned. However, more evaluations are needed in the form of large-scale studies and identification of other variables, eg, contrast volume, success in engagement, and other confounding factors.

Cardiac Catheterization Techniques
Traditionally, cardiologists use the femoral artery in the groin to start catheterization. But whenever possible, we use the radial artery in the wrist. This newer, less invasive approach has not yet been widely adopted. For some people, we still need to use the femoral approach.
Fibrinolytic therapy is most effective within 3 hours of symptom onset. The best outcomes occur when primary PCI is performed with a door-to-balloon time of less than 90 minutes and when symptom onset was less than 12 hours before the intervention.
Fluoroscopy is a method that provides real-time X-ray imaging. This is especially useful for guiding a variety of diagnostic and interventional procedures. The ability of fluoroscopy to display motion is provided by a continuous series of images produced at a maximum rate of 25-30 complete images per second.What is the procedure time for cardiac catheterization? ›
