Description of intervention(s) / exposure
This study will evaluate the performance of a new microcatheter Corsair Pro SC in percutaneous coronary intervention (PCI) for chronic total occlusions CTO. The Corsair Pro SC represents an evolution of the Asahi Corsair Pro microcatheter which is used commercially and approved internationally for use in CTO PCI. The main difference between the Corsair Pro and the Corsair Pro SC is the addition of a screw-like structure to the distal shaft. The changes made to the Corsair Pro SC are intended to facilitate the entry of the microcatheter into the CTO and create an anchor effect once the microcatheter is advanced into the CTO with the aim of improving wire manoeuvrability (torque and push) and crossability. During the CTO PCI the Corsair Pro SC will be advanced through a coronary guide catheter, over a wire, into the artery. The Corsair Pro SC will be used in combination with a coronary CTO wire to facilitate crossing of the CTO. Once the CTO has been successfully crossed the Corsair Pro SC microcatheter will be removed. Dilation of the lesion with a balloon and placement of coronary stent will then be performed. In this study the Corsair Pro SC microcatheter will be used during PCI in patients with CTO of their coronary arteries instead of a commercially available microcatheter. Performance of the microcatheter with be observed directly and recorded on coronary angiography using X-rays. The investigational procedures will be performed in the cardiac catheterisation laboratory of Wellington Regional Hospital by experienced Interventional Cardiologists
