Background: In patients with Kawasaki disease (KD), re-dilatation of coronary artery lesions (CAL) after regression is very rare. Here we report a case of KD with CAL re-dilatation after regression. Case report: A 15-year-old boy was diagnosed with KD at 1 year of age and was treated with intravenous immunoglobulin (IVIG, 400 mg/kg х 5 days). On day 14, echocardiography revealed CAL on the right coronary artery (RCA) and left coronary artery (LCA). Coronary arteriographic findings were as follows: segment 1, 3 mm in diameter; segment 6, 5 mm in diameter. He was prescribed aspirin, ticlopidine, and warfarin for 3 years. When he was 3 years old, coronary angiography showed complete CAL regression. His medications were discontinued and he underwent routine follow-up by echocardiography on which the CAL were not seen. At 14 years of age, coronary CT revealed re-dilatation of the LCA. Coronary angiography showed the same findings: 7 mm in diameter at the bifurcation between the LAD and the left circumflex artery, while the other regions were intact. He restarted aspirin and warfarin. The mechanism of CAL re-dilatation remains unclear; however, it is very important to follow patients carefully and routinely using echocardiography and/or coronary computed tomography, especially in cases with a history of CAL.

Detection of myocardial perfusion abnormalities using Tc-99m tetrofosmin was evaluated for sensitivity and specificity compared to coronary angiography. Between January 1996 and January 1998, exercise stress tests and myocardial scintigraphy were performed in 58 patients, followed by coronary angiography within 2 months. There were 48 males and 10 females, aged 33 to 72 years (mean, 57 years). The sensitivity and specificity of exercise stress tests were 64% and 68%, respectively, while the sensitivity and specificity of Tc-99m tetrofosmin scans were 88% and 75%, respectively, compared to angiography. For Tc-99m tetrofosmin scans, the sensitivity was 78% for the left anterior descending artery, 66% for the left circumflex artery, and 76% for the right coronary artery; specificity was 74% for the left anterior descending artery, 90% for the left circumflex artery, and 75% for the right coronary artery. It was concluded that Tc-99m tetrofosmin allowed high-quality myocardial perfusion imaging with results comparable to those obtained using thallium-201 chloride.

AbstractThe occurrence of super-dominant “single coronary artery” is an extremely rare and seldom reported phenomenon. The heart is dependent on a single vessel which makes its occlusion, if present, catastrophic. Here, the authors present an extremely rare combination of superdominant right coronary artery coexisting with absent left coronary artery and left circumflex artery with abnormal origin of left anterior descending artery from right coronary sinus. Precise morphological and physiological knowledge and evaluation of these anomalies is a must for opting the best available therapeutic modality and better prognosis.

Introduction. Combined endovascular interventions on carotid and coronary arteries are rare. Stenting of the unprotected coronary left main stem is a high risk procedure. We presented hemodynamically unstable patient with combined carotid artery and left main stem coronary artery stenting. Case report. A 78-year-old female patient was admitted to our institution for right carotid endaterectomy. The patient had 80% stenosis of the right carotid artery and occlusion of the left carotid artery. Coronary angiography revealed 70% ostial left main stenosis, occlusion of the right coronary artery and the left circumflex artery, and 80% stenosis of the left anterior descending artery. Simultaneous carotid artery endaterectomy and coronary artery by-pass grafting were considered. Due to high perioperative risk, surgery was rejected, and the patient was treated endovascularly with stenting of arteries occluded. The procedure was completed without complications and the patient was hemodynamically stabilised. Conclusion. This report illustrates simultaneous coronary and carotid stenting as a successfull lifesaving procedure.
