Insights
The Kimny guiding catheter is effective for ST-segment elevation myocardial infarction (STEMI) patients undergoing percutaneous coronary intervention (PCI). This universal catheter demonstrates high success rates for both left and right coronary artery interventions, offering a cost-effective solution.
Area of Science:
- Cardiovascular Interventions
- Interventional Cardiology
- Medical Device Technology
Background:
- The Kimny guiding catheter is a universal device for percutaneous coronary intervention (PCI).
- Its efficacy in non-emergent PCI is established, but its use in ST-segment elevation myocardial infarction (STEMI) is not well-documented.
Purpose of the Study:
- To investigate the feasibility and procedural success rates of the Kimny guiding catheter in STEMI patients.
- To evaluate its effectiveness for both left and right coronary artery interventions in acute myocardial infarction.
Main Methods:
- A retrospective analysis of 62 consecutive STEMI patients undergoing primary PCI with the Kimny guiding catheter.
- Evaluation of engagement and procedural success rates for left and right coronary artery PCI.
Main Results:
- High procedural success rate (98.3%) for primary PCI in STEMI patients.
- 100% success for left coronary artery and 94.4% for right coronary artery interventions.
- Excellent engagement rates for contralateral angiography and no observed ostial dissection.
Conclusions:
- The Kimny guiding catheter is feasible for primary PCI in STEMI patients.
- It achieves high procedural success, especially for left coronary artery interventions.
- The catheter offers a potentially cost-effective solution with reduced catheter usage.
Objectives:
The Kimny guiding catheter is a single universal guiding catheter used for performing percutaneous coronary intervention (PCI) in both the right coronary artery (RCA) and the left coronary artery (LCA). Although this guiding catheter has been shown to yield high procedural success rates in nonemergent conditions, its feasibility for patients with ST-segment elevation myocardial infarction (STEMI) remains unknown and therefore needs to be further investigated.
Materials And Methods:
We retrospectively enrolled 62 consecutive STEMI patients who underwent primary PCI using the Kimny guiding catheter from January 2016 through December 2017. We then evaluated the rates of engagement and procedural success for PCI of the LCA and RCA with the Kimny guiding catheter.
Results:
Primary PCI of the infarct-related artery (IRA) by means of the Kimny guiding catheter proved to be successful in 61 of the STEMI patients (98.3%). Besides, the procedural success rate was found to be 100% (44/44) for the LCA and 94.4% (17/18) for the RCA (P = 0.293). With regard to contralateral (non-IRA) angiography, engagement rates of 97.4% (38/39) and 100% (18/18) were obtained for the RCA and LCA, respectively, (P = 1.0). No coronary artery ostial dissection was observed during the procedures. The mean number of total catheters used for each patient turned out to be only 1.035.
Conclusion:
Using the Kimny guiding catheter for primary PCI is feasible and results in high procedural success rates, particularly for the treatment of the LCA, with fewer catheters, and at a lower cost.
