There are a lot of reports that decreased mortality and improvement of cardiac function are observed by shortening of the time from onset of acute myocardial infarction to recanalization. However, shortening of catheterization time, a part of the time, has not been examined. In 60 patients in a single-center retrospective study performed in Tokai University, the time from arterial puncture to reperfusion was shortened, and the time from arrival at hospital to reperfusion was also shortened. In 1275 patients in a multi-center retrospective study, moreover, the time from arterial puncture to reperfusion was significantly shortened by 4 minutes, and a significant decrease was also observed in the time from arrival at hospital to reperfusion.
Based on this result, the information shall be collected from prospective multi-center randomized study and analyzed to verify that the right and left dual-purpose guiding catheter is useful for shortening of reperfusion time in myocardial infarction.

SC-PCI Method
Primary PCI is initiated with a universal guiding catheter (Ikari left). The guiding catheter is used to contrast the left and right coronary arteries and PCI is started directly. This method does not require a catheter exchange. It is Single Catheter PCI (SC-PCI) method.
Conventional Method
Primary PCI is initiated with a diagnostic catheter. The catheter is used to contrast one of the coronary arteries. Then, the catheter is replaced with a contralateral side diagnostic catheter. Then, the catheter is replaced with a guiding catheter and PCI is started.

The SC-PCI method using the Ikari curve demonstrated a significant reduction in PCI procedure time while maintaining safety and procedural success in primary PCI for STEMI.

The baseline characteristics were well balanced between the 2 groups, except for higher heart rate at admission in the SC-PCI method compared with the C-PCI method. The mean age was 69 +/-13 years, and 81.6% of patients were men. As the study was conducted during the COVID-19 era (November 2022 to October 2023), there was variability between facilities in handling patients upon arrival at the hospital. Most facilities began primary PCI after submitting an antigen test and implementing infection control measures, without waiting for the antigen test results. However, some facilities performed chest CT scans to determine if patients had COVID-19 pneumonia, while others waited for the COVID-19 antigen test results before proceeding to the cath lab.
In total of 430 patients were enrolled and randomly assigned from 47 centers in Japan. The full analysis included 194 patients in the SC-PCI method and 186 patients in the C-PCI method, after excluding 20 patients from the SC-PCI method and 30 from the C-PCI method. The reasons for exclusion were patients with MINOCA, aortic dissection, pulmonary embolism, and those without an indication for primary PCI. Additionally, 16 patients (6 from the SC-PCI method and 11 from the C-PCI method) met exclusion criteria such as the need for a temporary pacemaker before PCI.
The follow-up completion rate was 100% at 30 days and 99.5% at 1 year. The secondary endpoints at 30 days follow-up included all-cause death, cardiac death, and hemorrhage were similar between both groups. BARC 3 or 5 bleeding at PCI puncture site was zero in both groups. Other endpoints such as recurrent MI, stroke at 30 days was also comparable. Prevalence of all-cause mortality, recurrent MI, stroke, and bleeding at 1 year follow-up was also similar between the 2 groups .
S2B time, which is the primary endpoint of the study, was significantly shorter in the SC-PCI method compared to the C-PCI method with 3 minute reduction of S2B time (15.8 +/- 10.9 minutes vs. 18.7 +/- 10.6 minutes, respectively, p=0.007) (Figure 2A, 2B, Table 3). On the other hand, the other secondary endpoints including D2B time, onset to door time, total ischemic time was similar between the 2 groups. Fluoroscopic time and dose, as well as volume of contrast was also similar between the 2 groups. Success rate of the SC-PCI method was 91.2% defined as completing the whole primary PCI procedure using only IL guiding catheter(s), 88.1% defined as completing the whole primary PCI procedure using an only single IL guiding catheter, and 85.1% defined as completing the whole primary PCI procedure using an only single IL guiding catheter with final TIMI 3 flow.
