Feasibility and Safety of Optical Coherence Tomography-Guided Percutaneous Coronary Intervention in Technically Challenging Lesions: A Case Series.

Optical coherence tomography (OCT) has better resolution than that of intravascular ultrasound. OCT provides vital information during percutaneous coronary intervention (PCI) procedure and is associated with better procedural and inhospital outcomes along with improved survival rate. In the present article, we have investigated three special cases including anomalous separate origin of the left circumflex artery at our hospital. We have reported the feasibility and safety of OCT-guided PCI in these three cases. [ABSTRACT FROM AUTHOR]
