Improvement of Left Ventricular Assist Device (LVAD) in Artificial Heart Using Particle Swarm Optimization
In this approach, the Left ventricular assist pump for patients with left ventricular failure isused. The failure of the left ventricle is the most common heart disease during these days. Inthis article, a State feedback controller method is used to optimize the efficiency of a samplingpump current. Particle Swarm Algorithm, which is a set of rules to update the position andvelocity, is applied...
متن کاملLeft Ventricular Pacing In Patients With Congestive Heart Failure
Cardiac resynchronisation therapy (CRT) using biventricular (BIV) pacing has proved its effectiveness to correct myocardial asynchrony and improve clinical status of patients with severe congestive heart failure (CHF) and widened QRS. Despite a different effect on left ventricular electrical dispersion, left univentricular (LV) pacing is able to achieve the same mechanical synchronisation as BI...
متن کاملassessment of subclinical left ventricular dysfunction in patients with chronic mitral regurgitation using torsional parameters described by tissue doppler imaging
background: left ventricular (lv) twist is due to oppositely directed apical and basal rotation and has been proposed as a sensitive marker of lv function. we sought to assess the impact of chronic pure mitral regurgitation (mr) on the torsional mechanics of the left human ventricle using tissue doppler imaging. methods: nineteen severe mr patients with a normal lv ejection fraction and 16 non-...
متن کاملComparison of permanent left ventricular and biventricular pacing in patients with heart failure and chronic atrial fibrillation: prospective haemodynamic study.
OBJECTIVE To compare clinical and haemodynamic variables between left ventricular and biventricular pacing in patients with severe heart failure; and to analyse haemodynamic changes during daily life and maximum exercise during chronic left ventricular and biventricular pacing. DESIGN Prospective single blinded randomised study with crossover. SETTING University hospital (tertiary referral ...
متن کاملEvaluation of right ventricular function in fetuses with hypoplastic left heart syndrome using tissue Doppler techniques.
OBJECTIVE The outcome of patients with hypoplastic left heart syndrome (HLHS) is influenced by right ventricular function. This study aimed to investigate whether differences in right ventricular function of fetuses with HLHS are present during gestation. METHODS This was a prospective study comprising 14 fetuses with HLHS (28 measurements obtained in total) and 28 normal control fetuses (31 ...
