Early outcomes with durable left ventricular assist device replacement using the HeartMate 3. J Thorac Cardiovasc Surg 2019; 160:132-139.e1. [PMID: 31740114 DOI: 10.1016/j.jtcvs.2019.09.151] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/02/2019] [Revised: 09/08/2019] [Accepted: 09/09/2019] [Indexed: 01/17/2023]
Abstract
BACKGROUND The HeartMate 3 (HM3) left ventricular assist device (LVAD) (Abbott, Inc, Chicago, Ill) is a fully magnetically levitated centrifugal implantable pump used to treat patients with chronic heart failure. The MOMENTUM (Multicenter Study of MagLev Technology in Patients Undergoing Mechanical Circulatory Support Therapy With HeartMate 3) trial demonstrated that patients treated with the HM3 experienced reduced need for reoperation for LVAD replacement compared with a control group receiving an axial flow design, Heartmate II (Abbott, Inc). However, there are few reports of using HM3 as the replacement pump in patients who already are supported by a durable LVAD and experience a device-related complication necessitating replacement. METHODS An institutional LVAD database was used to identify 19 consecutive patients who underwent pump replacement to HM3 (group 1) versus 85 consecutive control patients who underwent pump replacement to either Heartmate II or HeartWare Ventricular Assist Device (Medtronic Inc, Minneapolis, Minn) (group 2), at a single institution from January 2010 to August 2018. Patient baseline characteristic and outcomes were obtained from a prospectively maintained database. The primary endpoint was a composite of freedom from death or need for another replacement surgery. RESULTS There was no difference between the groups in heart failure etiology, indication for replacement, as well as the average days on the previous pump or the type of previous pump. The HM3 group did have a significantly greater body mass index (37 vs 31.6 P = .01), a greater number of previous LVAD implants (36.8% vs 5.9%, had 2 previous LVADs, P < .001), and a greater number of previous sternotomies (31.6% vs 7.1%, had 3 previous sternotomies, P = .001). No difference was found between the groups in terms of postoperative adverse event rates. With regards to the primary endpoint, the patients with HM3 replacements (group 1) versus group 2 experienced significantly greater freedom from either death or need for another replacement during the follow-up period (P = .039). During follow-up, there were no thrombosis events for the patients who received replacement with HM3. CONCLUSIONS LVAD replacement with HM3 can be performed safely and may be considered as the pump of choice in patients requiring LVAD replacement.

Abstract
Left ventricular assist devices (LVADs) are used to support patients with advanced systolic heart failure (HF). These patients might develop LVAD dysfunction and consequent HF symptoms. Occasionally, outflow graft obstruction is responsible for LVAD dysfunction. Here, we describe percutaneous techniques to repair the outflow graft and avoid re-sternotomy.

Abstract
The association of donor and recipient age with survival following adult heart transplantation has not been well characterized. The purpose of this study was to examine the impact of the relationship between donor and recipient age on post-transplant survival. We retrospectively reviewed the 2005-2018 UNOS heart transplant database for all adult recipients undergoing first-time isolated heart transplantation. The impact of donor and recipient age on survival was analyzed with Cox proportional hazards modeling using restricted cubic splines. A total of 25 480 heart transplant donor and recipient pairs met inclusion criteria. Unadjusted and adjusted Cox proportional hazards modeling demonstrated a near-linear association between increasing donor age and decreased survival; in addition, older and younger recipient age was associated with decreased survival. After adjustment, there was no significant interaction between donor and recipient age. Older donors decreased survival similarly in both older and younger recipients. Increasing donor age and both younger and older recipient age are independently associated with worsened post-heart transplant survival. The relationship between donor and recipient age does not significantly affect survival following heart transplant.

Abstract
BACKGROUND Patients considering destination therapy left ventricular assist devices (DT LVAD) often have high comorbid burden but the association between these comorbidities and post-decision outcomes is unknown. METHODS We included subjects in DECIDE-LVAD (NCT02344576), a stepped-wedge multicenter trial of patients considering LVADs, recording comorbidities per INTERMACS protocol. We compared decisional conflict, regret, perceived stress, quality of life (EQ-VAS), depression (PHQ-2), struggle with- and acceptance of illness by comorbid burden and amongst the most common comorbidities. RESULTS Of 239 patients, LVAD recipients (n = 164) and non-recipients (n = 75) had a similar proportion with ≥1 comorbidity (70% v. 80%, P = .09). Patients with comorbidities were younger regardless of LVAD implantation status. After adjusting for age, overall and amongst LVAD recipients, patients with ≥1 comorbidity had higher mean decision conflict at baseline (23.2 ± 1.5 vs. 17.4 ± 2.2), and at 6 months, higher stress (13.0 ± 0.6 vs. 10.4 ± 1.0) and struggle with illness (13.3 ± 0.4 vs. 11.1 ± 0.6) than those without comorbidities (P < .05). No difference was noted in decision regret, PHQ-2, EQ-VAS, acceptance of illness and survival overall and amongst LVAD recipients. Of the three most common comorbidities, while patients with pulmonary hypertension had worse decision regret, depression, stress and acceptance of illness at 6-month follow-up than those who did not have pulmonary hypertension, no difference was noted in patients with chronic renal disease or high body mass index. CONCLUSION Patients considering LVAD implantation with comorbidities experience increased decision conflict, stress and struggle with illness. These findings provide insights in the role comorbidities play in patient decision-making and decisional outcomes.

Abstract
BACKGROUND In two interim analyses of this trial, patients with advanced heart failure who were treated with a fully magnetically levitated centrifugal-flow left ventricular assist device were less likely to have pump thrombosis or nondisabling stroke than were patients treated with a mechanical-bearing axial-flow left ventricular assist device. METHODS We randomly assigned patients with advanced heart failure to receive either the centrifugal-flow pump or the axial-flow pump irrespective of the intended goal of use (bridge to transplantation or destination therapy). The composite primary end point was survival at 2 years free of disabling stroke or reoperation to replace or remove a malfunctioning device. The principal secondary end point was pump replacement at 2 years. RESULTS This final analysis included 1028 enrolled patients: 516 in the centrifugal-flow pump group and 512 in the axial-flow pump group. In the analysis of the primary end point, 397 patients (76.9%) in the centrifugal-flow pump group, as compared with 332 (64.8%) in the axial-flow pump group, remained alive and free of disabling stroke or reoperation to replace or remove a malfunctioning device at 2 years (relative risk, 0.84; 95% confidence interval [CI], 0.78 to 0.91; P<0.001 for superiority). Pump replacement was less common in the centrifugal-flow pump group than in the axial-flow pump group (12 patients [2.3%] vs. 57 patients [11.3%]; relative risk, 0.21; 95% CI, 0.11 to 0.38; P<0.001). The numbers of events per patient-year for stroke of any severity, major bleeding, and gastrointestinal hemorrhage were lower in the centrifugal-flow pump group than in the axial-flow pump group. CONCLUSIONS Among patients with advanced heart failure, a fully magnetically levitated centrifugal-flow left ventricular assist device was associated with less frequent need for pump replacement than an axial-flow device and was superior with respect to survival free of disabling stroke or reoperation to replace or remove a malfunctioning device.

Abstract
Advanced heart failure (HF) is a common condition that leads to significant suffering for patients and their families. Left ventricular assist devices (LVADs) can improve both the quantity and quality of life for those suffering with advanced HF. Palliative care clinicians are being asked with increasing frequency to assist HF teams to manage patients with LVADs in the preimplantation, post-operative, and end-of-life settings, although not all palliative care providers feel comfortable with this technology. Written by specialists in HF, geriatric cardiology, and palliative care, this article seeks to improve palliative care providers' knowledge of LVADs and will prepare palliative care teams to counsel and support LVAD patients and their families from pre-implantation to the end of life.

Abstract
Intra-aortic balloon pump (IABP) is often used to support patients in decompensated heart failure. Placement of the IABP via the axillary artery facilitates long-term support with the device and may allow for the conversion of an acute heart failure (HF) patient into a chronic HF patient using a modified weaning protocol; allowing for medical symptom management and removal of mechanical support. We will discuss strategies for supporting these complicated patients.

Abstract
Bleeding frequently occurs in patients undergoing placement of a left ventricular assist device (LVAD). Clinical factors that have been identified as contributing to peri-procedural bleeding include LVAD implantation after an acute myocardial infarction and preoperative use of antiplatelet agents. In this report, we describe the use of cangrelor for preoperative antiplatelet bridging to LVAD in five post myocardial infarction patients with cardiogenic shock that had recently undergone percutaneous coronary intervention. During the cangrelor bridging period, no cases of thrombotic or major bleeding events occurred. During the first week following LVAD implantation, two patients experienced a major bleeding (each case required chest exploration for suspected hemorrhage). To our knowledge, this is the first series describing cangrelor use for antiplatelet bridging in patients undergoing LVAD implantation. While this series suggest cangrelor could possibly be a safe and effective antiplatelet bridging strategy, further research is needed to identify the optimal antithrombotic strategy in cardiogenic shock patients undergoing LVAD implantation who have recently undergoing percutaneous coronary intervention.

Abstract
We aimed to study whether jugular venous distension (JVD) and peripheral edema were associated with worse outcomes in patients with acute heart failure in the Acute Study of Clinical Effectiveness of Nesiritide in Decompensated Heart Failure trial. Of 7,141 patients in Acute Study of Clinical Effectiveness of Nesiritide in Decompensated Heart Failure, 7,135 had complete data on baseline JVD and peripheral edema status. Patients were grouped according to baseline examination findings: (1) no JVD or peripheral edema; (2) JVD only; (3) peripheral edema only; (4) JVD and peripheral edema. We used unadjusted and adjusted logistic or Cox regression analyses to assess associations between groups and the outcomes of index length of stay (LOS), in-hospital mortality, 30- and 180-day all-cause mortality. Patients with peripheral edema (Groups 3 and 4) had higher body mass index, NT-proBNP and BNP values, and more co-morbid disease, and reduced left ventricular ejection fraction compared with patients in Groups 1-2. The median (25th-75th) LOS for Groups 1-4 was 6 (4-9), 5 (4-8), 7 (4-11), and 6 days (4-10), respectively. For the 30-day and 180-day outcomes, adjusted analyses found no significant difference in risk for patients presenting with JVD only or peripheral edema only as compared with patients without evidence of JVD or peripheral edema (p >0.05 for all). The presence of both JVD and peripheral edema was associated with an adjusted 24% increase in risk for all-cause mortality at 30 days, but no risk difference at 180 days. In conclusion, in patients with heart failure presenting to the hospital with dyspnea, the presence of peripheral edema is associated with a longer hospital LOS, but no difference in short- and long-term clinical outcomes when compared with patients wihout peripheral edema. The combination of peripheral edema and JVD identifies the highest risk cohort for poor clinical outcomes.

Abstract
OBJECTIVES This study aims to characterize caregivers of patients considering destination therapy left ventricular assist device (DT-LVAD) and evaluate the effectiveness of a shared decision-making (SDM) intervention. BACKGROUND Caregivers play an integral role in the care of patients with chronic illness. At the extreme, pursuing a DT-LVAD is a major preference-sensitive decision that requires high-level caregiver engagement. Yet, little is known about caregivers of patients considering DT-LVAD, and there is a paucity of research on the involvement of caregivers in medical decision-making. METHODS A 6-center, stepped-wedge trial was conducted. After varying time in usual care (control), sites were transitioned to an SDM intervention consisting of staff education and pamphlet and video decision aids (DAs). The primary outcome was decision quality, measured by knowledge and values-choice concordance. RESULTS From 2015 to 2017, 182 caregivers of patients considering DT-LVAD were enrolled (control group, n = 111; intervention group, n = 71). The median age was 61 years, 86.5% were female, and 75.8% were spouses. Caregiver knowledge (0% to 100%) improved from baseline to post-education in both groups: in the control group it improved from 64.2% to 73.3%; in the intervention group it improved from 62.6% to 76.4% (adjusted difference of difference: 4.8%; p = 0.08). At 1 month, correlation between stated values and caregiver-reported treatment choice was stronger in the intervention group (difference in Kendall's tau: 0.36, 95% confidence interval: 0.04 to 0.71; p = 0.03). Caregivers reported decisional conflict (0 to 100) at baseline (control group: 19.0 ± 2.1; intervention group: 21.4 ± 2.6), which decreased post-education more in the control group (control group: 9.0 ± 1.9, intervention group: 18.8 ± 2.4; p = 0.009). Caregivers in the control group were more likely to "definitely recommend" the educational materials than those in the intervention group (93.5% vs. 74.5%, respectively; p = 0.004). CONCLUSIONS An SDM intervention improved concordance between caregiver values and treatment choice for their loved ones but did not significantly impact knowledge. Caregivers found the DAs less acceptable than more biased educational materials and exposure to DAs led to higher conflict initially. These findings highlight the complexity of SDM involving caregivers of patients with chronic illness.

Abstract
The syndrome of frailty for patients undergoing heart or lung transplantation has been a recent focus for perioperative clinicians because of its association with postoperative complications and poor outcomes. Patients with end-stage cardiac or pulmonary failure may be under consideration for heart or lung transplantation along with bridging therapies such as ventricular assist device implantation or venovenous extracorporeal membrane oxygenation, respectively. Early identification of frail patients in an attempt to modify the risk of postoperative morbidity and mortality has become an important area of study over the last decade. Many quantification tools and risk prediction models for frailty have been developed but have not been evaluated extensively or standardized in the cardiothoracic transplant candidate population. Heightened awareness of frailty, coupled with a better understanding of distinct cellular mechanisms and biomarkers apart from end-stage organ disease, may play an important role in potentially reversing frailty related to organ failure. Furthermore, the clinical management of these critically ill patients may be enhanced by waitlist and postoperative physical rehabilitation and nutritional optimization.

Abstract
INTRODUCTION Limited data are available describing indications for and outcomes of therapeutic plasma exchange (TPE) in cardiac transplantation. METHODS In a retrospective study of patients who underwent cardiac transplantation at Duke University Medical Center from 2010 to 2014, we reviewed 3 TPE treatment patterns: a Single TPE procedure within 24 h of transplant; Multiple TPE procedures initiated within 24 h of transplant; and 1 or more TPE procedures beginning >24 h post-transplant. Primary and secondary outcomes were overall survival (OS) and TPE survival (TS), respectively. RESULTS Of 313 patients meeting study criteria, 109 (35%) underwent TPE. TPE was initiated in 82 patients within 24 h, 40 (37%) receiving a single procedure (Single TPE), and 42 (38%) multiple procedures (Multiple TPE). Twenty-seven (25%) began TPE >24 h after transplant (Delayed TPE). The most common TPE indication was elevated/positive panel reactive or human leukocyte antigen antibodies (32%). With a median follow-up of 49 months, the non-TPE treated and Single TPE cohorts had similar OS (HR 1.08 [CI, 0.54, 2.14], P = .84), while the Multiple and Delayed TPE cohorts had worse OS (HR 2.62 [CI, 1.53, 4.49] and HR 1.98 [CI, 1.02, 3.83], respectively). The Multiple and Delayed TPE cohorts also had worse TS (HR 2.59 [CI, 1.31, 5.14] and HR 3.18 [CI, 1.56, 6.50], respectively). Infection rates did not differ between groups but was independently associated with OS (HR 2.31 [CI, 1.50, 3.54]). CONCLUSIONS TPE is an important therapeutic modality in cardiac transplant patients. Prospective studies are needed to better define TPE's different roles in this patient population.

Abstract
Changes in heart transplantation (HT) donor and recipient demographics may influence the incidence of primary graft dysfunction (PGD). We conducted a retrospective study to evaluate PGD incidence, trends, and associated risk factors by analyzing consecutive adult patients who underwent HT between January 2009 and December 2014 at our institution. Patients were categorized as having PGD using the International Society for Heart & Lung Transplantation (ISHLT)-defined criteria. Variables, including clinical and demographic characteristics of donors and recipients, were selected to assess their independent association with PGD. A time-trend analysis was performed over the study period. Three-hundred seventeen patients met inclusion criteria. Left ventricular PGD, right ventricular PGD, or both, were observed in 99 patients (31%). Risk factors independently associated with PGD included ischemic time, recipient African American race, and recipient amiodarone treatment. Over the study period, there was no change in the PGD incidence; however, there was an increase in the recipient pretransplantation use of amiodarone. The rate of 30-day mortality was significantly elevated in those with PGD versus those without PGD (6.06% vs 0.92%, P = .01). Despite recent advancements, incidence of PGD remains high. Understanding associated risk factors may allow for implementation of targeted therapeutic interventions.

Abstract
BACKGROUND In an early analysis of this trial, use of a magnetically levitated centrifugal continuous-flow circulatory pump was found to improve clinical outcomes, as compared with a mechanical-bearing axial continuous-flow pump, at 6 months in patients with advanced heart failure. METHODS In a randomized noninferiority and superiority trial, we compared the centrifugal-flow pump with the axial-flow pump in patients with advanced heart failure, irrespective of the intended goal of support (bridge to transplantation or destination therapy). The composite primary end point was survival at 2 years free of disabling stroke (with disabling stroke indicated by a modified Rankin score of >3; scores range from 0 to 6, with higher scores indicating more severe disability) or survival free of reoperation to replace or remove a malfunctioning device. The noninferiority margin for the risk difference (centrifugal-flow pump group minus axial-flow pump group) was -10 percentage points. RESULTS Of 366 patients, 190 were assigned to the centrifugal-flow pump group and 176 to the axial-flow pump group. In the intention-to-treat population, the primary end point occurred in 151 patients (79.5%) in the centrifugal-flow pump group, as compared with 106 (60.2%) in the axial-flow pump group (absolute difference, 19.2 percentage points; 95% lower confidence boundary, 9.8 percentage points [P<0.001 for noninferiority]; hazard ratio, 0.46; 95% confidence interval [CI], 0.31 to 0.69 [P<0.001 for superiority]). Reoperation for pump malfunction was less frequent in the centrifugal-flow pump group than in the axial-flow pump group (3 patients [1.6%] vs. 30 patients [17.0%]; hazard ratio, 0.08; 95% CI, 0.03 to 0.27; P<0.001). The rates of death and disabling stroke were similar in the two groups, but the overall rate of stroke was lower in the centrifugal-flow pump group than in the axial-flow pump group (10.1% vs. 19.2%; hazard ratio, 0.47; 95% CI, 0.27 to 0.84, P=0.02). CONCLUSIONS In patients with advanced heart failure, a fully magnetically levitated centrifugal-flow pump was superior to a mechanical-bearing axial-flow pump with regard to survival free of disabling stroke or reoperation to replace or remove a malfunctioning device.

Abstract
IMPORTANCE Shared decision making helps patients and clinicians elect therapies aligned with patients' values and preferences. This is particularly important for invasive therapies with considerable trade-offs. OBJECTIVE To assess the effectiveness of a shared decision support intervention for patients considering destination therapy left ventricular assist device (DT LVAD) placement. DESIGN, SETTING, AND PARTICIPANTS From 2015 to 2017, a randomized, stepped-wedge trial was conducted in 6 US LVAD implanting centers including 248 patients being considered for DT LVAD. After randomly varying time in usual care, sites were transitioned to an intervention consisting of clinician education and use of DT LVAD pamphlet and video patient decision aids. Follow up occurred at 1 and 6 months. MAIN OUTCOMES AND MEASURES Decision quality as measured by knowledge and values-choice concordance. RESULTS In total, 135 patients were enrolled during control and 113 during intervention periods. At enrollment, 59 (23.8%) participants were in intensive care, 60 (24.1%) were older than 70 years, 39 (15.7%) were women, 45 (18.1%) were racial/ethnic minorities, and 62 (25.0%) were college graduates. Patient knowledge (mean test performance) during the decision-making period improved from 59.5% to 64.9% in the control group vs 59.1% to 70.0% in the intervention group (adjusted difference of difference, 5.5%; P = .03). Stated values at 1 month (scale 1 = "do everything I can to live longer…" to 10 = "live with whatever time I have left…") were a mean of 2.37 in control and 3.33 in intervention (P = .03). Patient-reported treatment choice at 1 month favored LVAD more in the control group (than in the intervention group (47 [59.5%] vs 95 [91.3%], P < .001). Correlation between stated values and patient-reported treatment choice at 1 month was stronger in the intervention group than in the control group (difference in Kendall's τ, 0.28; 95% CI, 0.05-0.45); however, there was no improved correlation between stated values and actual treatment received by 6 months for the intervention compared with the control group (difference in Kendall's τ, 0.01; 95% CI, -0.24 to 0.25). The adjusted rate of LVAD implantation by 6 months was higher for those in the control group (79.9%) than those in the intervention group (53.9%, P = .008), with significant variation by site. There were no differences in decision conflict, decision regret, or preferred control. CONCLUSIONS AND RELEVANCE A shared decision-making intervention for DT LVAD modestly improved patient decision quality as measured by patient knowledge and concordance between stated values and patient-reported treatment choice, but did not improve concordance between stated values and actual treatment received. The rate of implantation of LVADs was substantially lower in the intervention compared with the control group. TRIAL REGISTRATION clinicaltrials.gov Identifier: NCT02344576.
