The HFSA Advanced Heart Failure and Transplant Cardiology Fellowship Consensus Conference.

There is waning interest among cardiology trainees in pursuing an Advanced Heart Failure/Transplant Cardiology (AHFTC) fellowship as evidenced by fewer applicants in the National Resident Matching Program match to this specialty. This trend has generated considerable attention across the heart failure community. In response, the Heart Failure Society of America convened the AHFTC Fellowship Task Force with a charge to develop strategies to increase the value proposition of an AHFTC fellowship. Subsequently, the HFSA sponsored the AHFTC Fellowship Consensus Conference April 26-27, 2023. Before the conference, interviews of 44 expert stakeholders diverse across geography, site of practice (traditional academic medical center or other centers), specialty/area of expertise, sex, and stage of career were conducted virtually. Based on these interviews, potential solutions to address the declining interest in AHFTC fellowship were categorized into five themes: (1) alternative training pathways, (2) regulatory and compensation, (3) educational improvements, (4) exposure and marketing for pipeline development, and (5) quality of life and mental health. These themes provided structure to the deliberations of the AHFTC Fellowship Consensus Conference. The recommendations from the Consensus Conference were subsequently presented to the HFSA Board of Directors to inform strategic plans and interventions. The HFSA Board of Directors later reviewed and approved submission of this document. The purpose of this communication is to provide the HF community with an update summarizing the processes used and concepts that emerged from the work of the HFSA AHFTC Fellowship Task Force and Consensus Conference.

Efficacy of Decision Aids in The Use of Left Ventricular Assist Device in Patients With Advanced Heart Failure: A Systematic Review and Meta-Analysis of Randomized Control Trials.

Although left ventricular assist device (LVAD) implantation can improve survival in patients with end-stage heart failure, it is not without risk. Numerous complications are possible, and durable support requires substantial lifestyle changes. The use of various knowledge-assessment tools may allow for more informed patient decisions. To synthesize the totality of the evidence, we conducted a systematic review and meta-analysis to summarize the efficacy of decision aid (DA) use in patients with advanced heart failure who are eligible for LVAD. Any randomized controlled trial (RCT) evaluating the efficacy of DAs in patients considering LVAD was eligible for inclusion. A complete search of EMBASE and PubMed was conducted from the start until June 8, 2023. The primary outcome was patients' LVAD knowledge. Data extraction was performed independently by 2 reviewers. Data were pooled using a random-effects model. Of the 575 references, 2 RCTs randomizing 490 patients were included in this study. DAs were associated with no significant change in LVAD knowledge (standardized mean difference 0.07, 95% confidence interval -0.24 to 0.39, p = 0.64) or decisional conflict (mean difference -1.48, 95% confidence interval -5.28 to 2.32, p = 0.45). The certainty of the evidence ranged from moderate to very low. The use of DAs in LVAD-eligible patients with advanced heart failure resulted in no difference in patients' knowledge of LVAD after LVAD education. The findings from this study will aid in the power analysis of a well-designed RCT to evaluate and encourage further investigation into the efficacy and relevance of DAs in preparing patients for a life with LVAD.

Donor Oversizing Results in Improved Survival in Patients with Left Ventricular Assist Device.

Donor to recipient undersizing can result in diminished graft survival. The United Network for Organ Sharing database was retrospectively queried from January 2008 to December 2013 to identify adult patients who underwent heart transplantation. This population was divided into those without and with a left ventricular assist device (LVAD) at the time of transplant. Both groups were further subdivided into three groups: donor:recipient body mass index (BMI) ratio <0.8 (undersized), ≥0.8 and ≤1.2 (matched), and >1.2 (oversized). Kaplan-Meier analysis was used to compare graft survival. Cox regression analysis was used to identify factors affecting graft survival time. There was no difference in mean graft survival between undersized, matched, and oversized groups in patients without an LVAD (p = 0.634). Mean graft survival was significantly worse for undersized patients with an LVAD when compared with matched and oversized patients (p = 0.032). Cox regression revealed age, creatinine, waitlist time, United Network for Organ Sharing status, BMI ratio, and total bilirubin as significant factors affecting graft survival time. A donor to recipient BMI ratio of ≥1.2 results in significantly improved long-term graft survival for patients with an LVAD at the time of heart transplantation compared with patients with a BMI ratio of <1.2. An oversized organ should be considered for patients supported with an LVAD.

Treatment strategies for myocardial recovery in heart failure.

OPINION STATEMENT: Heart failure is a progressive disorder characterized by adverse left ventricular remodeling. Until recently, this has been thought to be an irreversible process. Mechanical unloading with a left ventricular assist device (LVAD), particularly if combined with neurohormonal blockade with heart failure medications, can lead to a reversal of the heart failure phenotype, a process called "reverse remodeling." Reverse remodeling refers to the regression of pathologic myocardial hypertrophy and improvement in LV chamber size that can occur in response to treatment. Myocardial recovery is the sustained normalization of structural, molecular, and hemodynamic changes sufficient to allow explant of the LVAD. Despite the fact that reverse remodeling is commonly seen in LVAD patients in clinical practice, myocardial recovery sufficient to allow device explantation is still rare. Previous experience suggests that young patients with short duration of heart failure and less myocardial fibrosis may be more likely to recover. Alternatively, it may just be that clinicians make a greater effort to recover these subgroups. A combined approach of mechanical unloading with LVADs and pharmacological management, together with regular testing of underlying myocardial function with the pump reduced to a speed at which it is not contributing, can increase the frequency of sustained recovery from heart failure. The goal is to achieve optimal unloading of the myocardium, combined with pharmacologic therapy aimed at promoting reverse remodeling. Myocardial recovery must be considered as a therapeutic target. Clinical variables such as pump speed and blood pressure must be optimized to promote maximal unloading, leading to reverse remodeling and myocardial recovery. Frequent echocardiographic and hemodynamic evaluation of underlying myocardial function must be performed. The combination of LVAD therapy with optimal neurohormonal blockade appears promising as an approach to myocardial recovery. In addition, there is a growing body of translational research which, when combined with LVADs, may further promote more durable recovery. Strategies to thicken the myocardium to enhance the durability of recovery prior to explantation, such as clenbuterol (which induces "physiological hypertrophy"), or intermittently reducing the pump speed to increase myocardial load may be beneficial. Emergence of cardiac stem cells and alternative biologic agents, when added to current therapies, may have a complementary role in promoting and maintaining myocardial recovery. This review will summarize both current strategies and emerging therapies.

Heart transplant survival outcomes for adriamycin-dilated cardiomyopathy.

In 2015, there will be an estimated 11.3 million cancer survivors. With an increasing population of cancer survivors, it is imperative to understand the treatment options available and outcomes for chemotherapy-related cardiomyopathy. Anthracycline-based chemotherapy causes heart failure in approximately 5% of patients. Orthotopic heart transplantation (OHT) is an option for cancer survivors in complete remission who develop end-stage heart failure. We examined retrospective OHT data collected from the United Network of Organ Sharing from 1987 to 2011. The primary aim was to characterize the survival in patients with either the primary diagnosis of "dilated cardiomyopathy: Adriamycin" (DCA) versus "all other" causes of cardiomyopathy. The secondary aim was to define the differences in the primary cause of death and to describe the temporal relationship of DCA OHT. The United Network of Organ Sharing database identified 453 OHTs for the diagnosis of DCA and 51,312 OHTs for all other causes of cardiomyopathy. The DCA group was significantly younger with a greater percentage of women. After adjusting for age, gender, and history of malignancy, the 10-year survival curves showed that patients with DCA have an improved survival compared to those with all other causes of cardiomyopathy (hazard ratio 1.28, p = 0.026). No difference was found in the primary cause of death between the 2 groups. A statistically significant increasing temporal trend was seen in the number of OHTs for the diagnosis DCA. In conclusion, patients who undergo OHT for DCA have favorable 10-year survival, making OHT a good therapeutic option for end-stage heart failure due to anthracyclines. Additionally, no increased risk of cancer-related deaths was found in the DCA group, demonstrating that recurrent malignancy does not affect long-term survival. The temporal trends demonstrated that DCA remains a significant problem for cancer survivors.
