Evaluation the results of method -jailed wire anchoring- to increase guiding catheter support during coronary angioplasty (case series study)

Introduction: Failure to deliver stents during percutaneous coronary interventions (PCI) is one of the major causes of procedural failure that may occur in up to 5% of cases and will be associated with adverse clinical outcomes. Insufficient guiding catheter support is one of the main causes of stent delivery failure. Various techniques have been developed to increase guiding catheter support. In this study we want to describe new method jailed wire anchoring technique. Material and Methods: This study is case series which took place in Emam Hospital angioplasty department. We identified cases that need to increase guiding support during angioplasty and standard supportive techniques fail to deliver a stent to a distal diseased segment and there is additional proximal disease that the operator intends to stent. All of the patient’s data such as patient’s characteristics, cardiac disease risk factors, Lesion characteristics and procedural strategies prior to jailed wire anchoring technique designed into the questionnaire. After completing the questionnaires, the data analyzed with SPSS v16. Results: The study population consisted of 10 men (71.4%) and 4 women (28.6%) with a mean age of 65/14± 8/40 years. More than one-half of the patients (57/1%) had hypertension. Vascular access site in all patients was the right femoral artery. Specific adverse anatomic features included calcification in 7 (50%), tortuosity in 4 (28.5%), ostium anomaly in 2 (14/2%) and CTO in 1(7/1%).Target vessels included 10 RCA, 3 LAD and 1 LCX. Our method was successfully increased guiding catheter support cases and lead to successful stent delivery in all 14. Conclusion: The Jailed Wire Anchoring Technique is a valuable tool to increasing guiding catheter support to aid distal stent delivery when standard supportive techniques fail to deliver a stent to a distal diseased segment and there is additional proximal disease that the operator intends to stent.
