심혈관 OCT의 임상적 응용 = Clinical Applications of Intracoronary OCT (Invited Paper)

국문 초록 (Abstract)

심혈관 질환은 심장마비의 가장 흔한 원인으로 관상동맥의 협착으로 심근에 산소와 영양분을 제대로 공급하지 못하게 되어 발생하게 된다. 이를 내과적으로 치료하기 위해 심혈관 중재술이 시행되는데 이때 스텐트 삽입 여부, 위치, 크기, 그리고 스텐트 삽입 후 혈관벽과의 밀착 여부를 평가하기 위해 혈관 내 광간섭단층촬영(OCT, optical coherence tomography) 내시경 진단검사를 시행한다. 본 논문에서는 이러한 심혈관 OCT 원리와 기술 동향, 그리고 실제 의료현장에서 심혈관 OCT의 임상적 응용 및 활용가치를 소개하고자 한다.

다국어 초록 (Multilingual Abstract)

The most common cause of a heart attack is known as coronary artery disease, which narrows the arteries and reduces the blood flow to the heart. To treat coronary artery stenosis, percutaneous coronary intervention (PCI) (a nonsurgical procedure to install a stent, which holds the artery wall open) is performed. Intracoronary optical coherence tomography (OCT) is a catheter-based, invasive optical imaging system. To determine whether PCI is appropriate, and to perform stent evaluation in a catheterization laboratory, OCT examinations are carried out. This review details the fundamental principles and technological status of intracoronary OCT imaging, and discusses the ongoing clinical applications to determine the benefits of OCT-guided PCI.
