Background: Optical Coherence Tomography (OCT) is a well-established and proven tool to help improve outcomes in patients with coronary disease Our aim is to describe the patient characteristics, indications for OCT and how OCT affected patient management Methods: All patients who had undergone OCT at MMH during 2018- early 2020 were analysed The angiograms, discharge summaries and OCTs were then reviewed Results: 68 patients underwent OCT and 45 (66%) were male The average age was 58 (26-89) and the average BMI was 29kg/m2 (19-69) 30(44%) were Māori or Pacific Islanders, 24 (35%) were NZ Europeans One operator (DS) performed 40% of the procedures with equivalent numbers between the four other operators The LAD was studied on 48(71%) occasions, followed by the RCA 13 (19%), LCX / OM vessels 8 (12%) In 8 cases more than one vessel was studied 49(72%) cases were for acute coronary syndrome (ACS) evaluation, other indications included stent trial follow up, elective PCI for stable coronary disease, and thrombus/plaque evaluation 39(57%) had PCI performed and of these 17(44%) had further stent post dilatation after the OCT to optimise stent deployment OCT avoided the use of stents in 10 cases One case of OCT catheter induced spasm causing VT requiring cardioversion and one patient died in hospital unrelated to the OCT due to the underlying condition Conclusion: OCT is a safe and effective tool in planning and optimising PCI in patients undergoing coronary angiography OCT altered the management in changed treatment in a large number of cases
