Destination Therapy with the magnetically levitated HVAD
Results Our data show preoperative values including age [67.1 y+5.0 y] and INTERMACS classification [range 2-4]. The indication for DT includes old age, compliance problems, and severe comorbidities. Outcome data demonstrate a low 30-day mortality in elective DT patients (100% survival). Mean follow up after permanent Heartware implantation was in average 544 days (range, 160-1512). 1 year surv...
متن کاملAccuracy of the HVAD Pump Flow Estimation Algorithm.
Controller algorithms are an important feature for assessment of ventricular assist device performance. Flow estimation is one algorithm implemented in the HeartWare continuous-flow ventricular assist device pump system. This parameter estimates flow passing through the pump and is calculated using speed, current, and hematocrit. In vitro and in vivo studies were conducted to assess the algorit...
متن کاملHVAD Flow Waveform Morphologies: Theoretical Foundation and Implications for Clinical Practice
Continuous-flow ventricular assist device (cfVAD) performance and patient hemodynamic conditions are intimately interrelated and dynamic, changing frequently with alterations in physiologic conditions, particularly pre- and afterloading conditions. The Heartware cfVAD (HVAD) provides a unique feature among currently approved VADs of providing an estimated instantaneous flow waveform, the charac...
متن کاملSuccessful use of the HeartWare HVAD rotary blood pump for biventricular support.
Left ventricular assist devices (LVADs) using rotary blood pump technology led to significant improvement of results in left ventricular failure. However, patients with concomitant right ventricular failure have not benefited from this new technology so far. We report on the first successful use of 2 HeartWare HVAD centrifugal pumps (HeartWare International, Inc, Framingham, Mass) in biventricu...
متن کاملA New Basis Function Approach to ’t Hooft-Bergknoff-Eller Equations
We analytically and numerically investigate the ’t Hooft-Bergknoff-Eller equations, the lowest order mesonic Light-Front Tamm-Dancoff equations for U(NC) and SU(NC) gauge theories. We find the wavefunction can be well approximated by new basis functions and obtain an analytic formula for the mass of the lightest bound state. Its value is consistent with the precedent results. PACS number(s): 11...
