Zero contrast retrograde chronic total occlusions percutaneous coronary intervention: a case series.

ABSTRACT:

Introduction

Percutaneous coronary intervention (PCI) in patients with advanced chronic kidney disease (CKD) is associated with a high risk of contrast-induced nephropathy and resulting progression of CKD to need for renal replacement therapy. Chronic total occlusions (CTO) PCI is increasingly utilized in the treatment of refractory stable angina and ischaemic heart failure. Recent studies have described the feasibility of 'minimal' or 'zero' contrast PCI by employing intravascular imaging and intra-coronary physiology to guide successful stent implantation with resolution of ischaemia. We extended these techniques to CTO lesions via the retrograde approach.

Case presentation
