Cardiovascular outcomes following Kawasaki disease in Moscow, Russia: A single center experience

Background: Awareness of Kawasaki disease (KD) is emerging in Russia but the diagnosis is still often missed. Methods: This is a retrospective study of 303 children with KD who received care at a single center in Moscow over the period from 2004 to 2016. Results: Overall, coronary artery aneurysms were documented in 91 (30,0%) of 303 patients and transient ectasia in 40 (13,2%). Intracoronary thrombi were found in 12 of 15 patients with giant aneurysms and in 3 patients with medium-sized aneurysms. Conclusion: The patients with KD in the Moscow region had typical features of the disease described in the literature but the proportion of patients with coronary artery aneurysms was higher than reported from other countries. We assume that this is due to delayed treatment, which has gradually improved over time. Increased awareness of KD in Russia is critical to ensure timely diagnosis and treatment.
