Heart transplantation is the recommended treatment method for patients with advanced heart failure that is refractory to clinical treatment. Due to the progressive severity of these patients and the i...
This work is a literature review, developed with scientific production in the period from 2010 to 2020, that focus on circulatory assist devices as a bridge for heart transplantation....
These devices are characterized as a bridge for transplantation. Short-term or temporary devices are those used for hemodynamic support to stabilize the individual clinically in the presence of refrac...
According to the present study, it is possible to observe that there is a wide variety of devices available on the market, enabling the most appropriate choice according to the patient's need....
VAD support for early graft failure after HTx is a rare event in pediatrics....
We retrospectively describe our single-center experience with post-HTx VAD support in a cohort of patients transplanted between 01/05 and 12/20....
Nine patients underwent VAD insertion in the early post-HTx period [median age 6.1 years (Range 0.3-20.3), median weight 17.6 kg (Range 3.5-65.0), and congenital heart disease (67%)]. Of the nine pati...
In this small patient series, post-HTx VAD was a useful measure in selected patients especially with pre-HTx planning. However, more shared experiences to verify these findings are needed....
Improvement in continuous-flow left ventricular assist device (CF-LVAD) technology has translated to better outcomes for patients on CF-LVAD support as a bridge-to-transplant. However, data are lackin...
The United Network for Organ Sharing (UNOS) database was used to identify adult patients listed for heart transplant (HTx) or HKTx from January 1, 2009 to March 31, 2017. Patients were followed from t...
Overall, 26 638 patients registered for transplant were analyzed. 25 111 (94%) were listed for HTx, and 1527 (6%) for HKTx. 7683 (29%) patients listed for HTx had CF-LVAD support. For those listed for...
Post-transplant survival is comparable between HTx and HKTx, and early survival is similar between HTx patients and those listed for HTx with CF-LVAD support. However, outcomes on the waitlist for HKT...
Right heart failure (RHF) is a well-known complication after left ventricular assist device (LVAD) implantation and portends increased morbidity and mortality. Understanding the mechanisms and predict...
We reviewed the existing definitions of RHF including its potential mechanisms in the context of durable LVAD implantation and currently available medical and device therapies. We performed a literatu...
RHF remains a common complication after LVAD implantation. However, existing knowledge gaps limit clinicians' ability to adequately address its consequences. Early identification and management are cr...
In object-oriented or acausal modelling, components of the model can be connected topologically, following the inherent structure of the physical system, and system equations can be formulated automat...
A comprehensive object-oriented model of the cardiovascular system with a VAD is developed in MATLAB/SIMSCAPE, and its hemodynamic behaviour is studied. An analytically derived pump model is calibrate...
Regurgitation, suction, and optimal speeds are identified, and trends in different hemodynamic parameters are observed for the simulated pathophysiological conditions. Using pertinent parameters in di...
The current research provides a comprehensive and validated framework for the preclinical evaluation of cardiac assist devices. Due to its object-oriented nature, the featured model is readily modifia...
Generally, heart transplantation with marginal donor allografts is reserved for a subset of high-risk patients. However, given the improved survival rates for patients on left ventricular assist devic...
This was a retrospective cohort study of adults (≥18 years) listed for heart transplantation between 2010 and 2022 in the Organ Procurement and Transplantation Network database. A previously validated...
Of 5,713 patients with left ventricular assist devices, 4,683 (82%) comprised the left ventricular assist devices group and 1,030 (18%) the marginal group. The marginal cohort was older (57 [49-64] vs...
Our study validates the superiority of transplantation relative to left ventricular assist devices but also underscores the survival benefit of heart transplantation with marginal donor allografts, ev...
Biventricular assist devices (BiVADs) for pre-heart transplant care is rare. The outcomes of pretransplant BiVAD support after the 2018 heart transplant allocation policy change are entirely unknown a...
The new donor heart allocation system prioritizes candidates supported by temporary devices. However, waitlist and posttransplant outcomes in candidates with durable left ventricular assist device (LV...
Durable left ventricular assist devices (VADs) improve survival in eligible patients, but allocation has been associated with patient race in addition to presumed heart failure (HF) severity....
This study sought to determine racial and ethnic differences in VAD implantation rates and post-VAD survival among patients with ambulatory HF....
Using the INTERMACS (Interagency Registry of Mechanically Assisted Circulatory Support) database (2012-2017), this study examined census-adjusted VAD implantation rates by race, ethnicity, and sex in ...
VADs were implanted in 2,256 adult patients with ambulatory HF (78.3% White, 16.4% Black, and 5.3% Hispanic). The median age at implantation was lowest in Black patients. Implantation rates peaked bet...
Black and White patients with ambulatory HF had similar VAD implantation rates but rates were lower for Hispanic patients. Survival differed among the 3 groups, with the highest estimated survival at ...
Women of reproductive age are increasingly undergoing heart transplantation (HT) or left ventricular assist device (LVAD) implantation for advanced heart failure. This review is intended to give an ov...
Heart transplant recipients are at increased risk for graft rejection, renal dysfunction, preeclampsia and worsening of comorbidities (hypertension and diabetes). Patients with LVAD are at higher risk...
A multidisciplinary approach with close antepartum and postpartum surveillance is recommended....
