MARTINEZ-GARCIA, Alfonso et al. Left ventricular longitudinal systolic strain in children with history of Kawasaki disease. Arch. Cardiol. Méx. [online]. 2016, vol.86, n.3, pp.196-202. ISSN 1665-1731.


Kawasaki disease (KD) is a systemic vasculitis that affects young children. Coronary artery aneurisms, ectasia and stenosis are its main complications and may lead to ischemic heart disease or sudden death. Echocardiography evaluation it's mandatory in all patients with history of KD. Left ventricular longitudinal systolic strain (LVLSS) measured by speckle tracking it's an accurate tool to evaluate global and segmental left ventricle mechanics. Clinical utility of LVLSS in children with KD hasn't been established. The goal of this study was to analyse if the presence of coronary lesions alters segmental LVLSS and if there is a relationship with the affected coronary territory.


Case series. A complete transthoracic echocardiography with LVLSS was performed in children with history of KD with at least 6 months after the acute phase.


Nine patients where studied, with a median age of 6 years (minimum 2 and maximum 17). A percentage of 56 were male, and 77% had coronary aneurisms. An abnormal LVLSS was found in 56% of the population studied. All of the patients that had an abnormal LVLSS had coronary aneurisms with stenosis or complete occlusion confirmed by invasive coronary angiography and abnormal Nuclear Medicine perfusion scans.


On the population studied, all patients with an abnormal LVLSS had obstructive coronary lesions and ischemic heart disease.
