Hemolytic Performance in Two Generations of the Sputnik Left Ventricular Assist Device: A Combined Numerical and Experimental Study.

Background: Currently, left ventricular assist devices (LVADs) are a successful surgical treatment for patients with end-stage heart failure on the waiting list or with contraindicated heart transplantation. In Russia, Sputnik 1 LVAD was also successfully introduced into clinical practice as a bridge-to-transplant and a destination therapy device. Development of Sputnik 2 LVAD was aimed at miniaturization to reduce invasiveness, optimize hemocompatibility, and improve versatility for patients of various sizes.

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

Awareness of Kawasaki disease (KD) is emerging in Russia but the diagnosis is still often missed. 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. Overall, coronary artery aneurysms were documented in 91 (30,0%) of 303 patients and transient ectasia in 40 (13,2%).

[Giant Aneurisms of Coronary Arteries in the Kawasaki Syndrome].

Background: Kawasaki disease is an acute systemic vasculitis of childhood with possible coronary artery involvement which can cause acute coronary syndrome in children and young adults.

Purpose: to study clinical and demographic characteristics of patients with Kawasaki disease with giant coronary aneurysms, to assess long-term prognosis in these patients.

Material And Methods: In 2003-2015 262 children with Kawasaki disease were examined in the University Children Hospital of the I.

Non-invasive evaluation of the kinematic activity of the intact left ventricle of the heart.

Vector analysis of the movement of the epicardium has been used to calculate the energy efficiency of different parts of the left cardiac ventricle. The protocol based on the results of these calculations would allow the calculation of the potential power of myocardial contraction.

Experimental Study of Kinematic Activity of Left Ventricular Myocardium.

A method of invasive and non-invasive examination of epicardial motion was tested on domestic pigs (n=15). The invasive study employed a contact kinematic sensor of the epicardial wall motion, which determined the amplitude, velocity, and angular parameters of examined epicardial region. A non-invasive assessment of the epicardial kinematics based on echocardiographic 2D Velocity Vector Imaging and ECG recoding used to determine the heart electrical axis.
