Abstract

Stenosis of Left main coronary artery is a subgroup of risk for high disease of coronary artery however, its appearance may be misinterpreted by CT angiography. In five patients with clinically very suspicious and angiographically limited LMCA disease Coronary CT angiography was performed. CCTA cross-sectional image was used to measure the diameter. Objective: To know the findings of CT Angiography of Left Main Coronary Artery. Place and Duration: The Study was performed in Nishtar Hospital, Multan for the period of 1 year from Jan 2016 to Jan 2017 after the approval from the ethical committee. Patients and Methods: This is an observational Study Performed on 130 Individuals with Changes in ECG due to left main coronary artery stenosis and findings of CT Angiography were compared for the correlation. Conclusion: On our observations based study, we believe that CCTA may have very important diagnostic role in LMCA patients with lesions of CT angiographic ally uncertain or unresponsive AMC lesions and should be considered for the evaluation of patients selected for study before undergoing bypass coronary surgery. A suitable gold standard such as IVUS is required to confirm the CCTA for the main root stenosis. Key words: CT Angiography, LMCA, Stenosis.
