چکیده
Left Ventricular Assist Devices (LVADs) improve survival in patients with heart failure. However, an increased burden of ventricular tachycardia (VT) can occur following LVAD implantation. The role ablation the treatment VT for recipients and timing when should is unclear. To determine mortality who required We retrospectively reviewed all received a from January 2014 to February 2021 included those underwent after placement. composite endpoints transplant, lost follow up, or last date data collection. Event failure was defined as patient death. Survival rates were calculated Kaplan-Meier analysis. Rate event per patient-year incident death rate (IR) compared between groups by ratio 95% confidence intervals (IRR [95% CI]). analysis performed using STATA. 36 Of those, 21 (58%) had documented prior placement 14 (42%) de novo Within 30 days, one died (IR 0.339 over 2.95 patient-years); within year, four 0.128 31.1 two years, ten 0.183 54.5 eight twenty 0.217 92.2 patient-years).

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...

progressive endo-epicardial dissociation, transforming the atria into an electrical double layer of dissociated waves that constantly ‘feed’ each other. Figure 1 gives a diagrammatic presentation of the double layer hypothesis. In Figure 1A and B, a rotor is compared with an epicardial breakthrough. Whereas a rotor at best can maintain itself, endo-epicardial breakthroughs act as multiplication...
متن کاملDesign an Equivalent Left Ventricular Assist Device for Medical Equipment Labs
LVAD is a mechanical pump supporting a weak heart function and blood flow. Sometimes, the heart may not recover fast enough to take over the pumping action immediately after surgery, in such patients a temporary support device has been employed to maintain the pumping action until the patient’s own heart recovers. This device can be considered as a temporary alternative before the process of ar...
