Abstract
Guidewire Fracture during Crossing A Chronic Coronary Total Occlusion: A Troublesome Experience
Highlights
Increased interest focusing on coronarychronic total occlusions has emerged since several studies have proven improved cardiovascular outcomes and quality of life after successful revascularization of achronic total occlusion (CTO) [1]
Advanced antegrade and retrograde techniques performed with dedicated equipment have provided significant improvements in procedural success and decrease periprocedural complications leading to percutaneous coronary intervention (PCI) failure [2,3]
The reported incidence of guidewire fracture varies between 0.02- 0.08 % of cases undergoing PCI [4,5]
Summary
A 56-years old man was admitted to our cardiology outpatient department with Canadian Cardiac Society Class II stable angina pectoris that has been continuing for the last six months. His past medical history revealed hypertension and hyperlipidemia. Myocardial perfusion scintigraphy demonstrated inferior ischemia and diagnostic coronary angiography showed a long CTO of the right coronary artery (RCA) and retrograde distal filling of RCA from septal collateral channels of left anterior descending artery (Figure 1). Afterwards, percutaneous coronary intervention (PCI) to CTO of RCA was planned. We decided to recanalize the occluded vessel by
