Whole heart coronary magnetic resonance angiography (MRA) was performed in a 57-year-old man with a provisional diagnosis coronary artery aneurysm due to Kawasaki disease. MRA revealed aneurysms in the left anterior descending artery and the left circumflex artery. It also revealed stenosis in the left anterior descending artery and occlusion in the right coronary artery with a collateral vessel connecting between the proximal and distal sites of the occlusion.

The patient was referred because of chest pain and worsening of dyspnea. Electrocardiogram showed T-wave inversions on the precordal leads, and acute coronary syndrome was suspected.

In this report, we describe coronary artery abnormalities in a young adult with Kawasaki disease. MSCT detected a giant coronary artery aneurysm, coronary artery stenosis in the first diagonal artery, and a multi-layered structure in the right coronary artery and the left circumflex artery.

Methods And Results: MSCT was performed in 31 patients with ACS and 26 patients with SA and intravascular ultrasound (IVUS) was performed in 28 of these 57 patients. In both the MSCT and IVUS analyses, coronary artery remodeling was assessed by the remodeling index (RI): RI >1.
Multislice spiral computed tomography (MSCT) is a new non-invasive imaging technique for detecting coronary artery disease. It allows direct visualization of not only the lumen of the coronary arteries, but also plaque within the artery. Identification of soft plaques is of the utmost importance in the therapeutic decision making for patients with acute coronary syndrome (ACS), including acute myocardial infarction and unstable angina pectoris.

In this report, we describe a patient with stable angina in whom the regression of the plaque was documented by serial MSCT examinations. In the patient, a 46-year-old man with stable angina, MSCT revealed a stenotic lesion at the proximal portion of the left anterior descending artery.

Therefore, non-invasive assessment of the status of the coronary artery is of utmost importance in patient management. Multislice spiral computed tomography (MSCT) permits non-invasive visualization of the entire coronary artery system and was used in the evaluation of 4 patients with KD.

The study group comprised 54 consecutive patients undergoing MSCT and CAG. MSCT was performed using a SOMATOM Volume Zoom (4-detector-row, Siemens, Germany) with slice thickness 1.
View Article and Find Full Text PDFAlthough the excellent spatial resolution of multislice spiral computed tomography (MSCT) enables the coronary arteries to be visualized, its limited temporal resolution results in poor image reproducibility because of cardiac motion artifact (CMA) and hence limits its widespread clinical use. A novel retrospectively ECG-gated reconstruction method has been developed to minimize CMA. In 88 consecutive patients, the scan data were reconstructed using 2 retrospectively ECG-gated reconstruction methods.
