Invasive Implanted Hemodynamic Monitoring in Patients with Complex Congenital Heart Disease: State-of-the-Art Review.

As the number of patients with congenital heart disease (CHD) continues to increase, the burden of heart failure (HF) in this population requires innovative strategies to individualize management. Given the success of implanted invasive hemodynamic monitoring (IHM) with the CardioMEMSTM HF system in adults with acquired HF, this is often suggested for use in patients with CHD, though published data are limited to case reports and case series. Therefore, this review summarizes the available published reports on the use of IHM in patients with complex CHD, describes novel applications, and highlights future directions for study. In patients with CHD, IHM has been used across the lifespan, from age 3 years to adulthood, with minimal device-related complications reported. IHM uses include (1) prevention of HF hospitalizations; (2) reassessment of hemodynamics after titration of medical therapy without repeated cardiac catheterization; (3) serial monitoring of at-risk patients for pulmonary hypertension to optimize timing of heart transplant referral; (4) and hemodynamic assessment with exercise (5) or after ventricular assist device placement. IHM has the potential to reduce the number of cardiac catheterizations in anatomically complex patients and, in patients with Fontan circulation, IHM pressures may have prognostic implications. In conclusion, though further studies are needed, as patients with CHD age and HF is more prevalent, this tool may assist CHD physicians in caring for this complex patient population.

A Comparison of Quality-Adjusted Life Years in Older Adults after Heart Transplantation Versus Long-Term Mechanical Support: Findings From the SUSTAIN-IT study.

BACKGROUND: The quality-adjusted life year (QALY) measures disease burden and treatment, combining overall survival and health-related quality of life (HRQOL). We estimated QALYs in three groups of older patients (60-80 years) with heart failure (HF) who underwent heart transplantation (HT, with pre-transplant mechanical circulatory support [HT MCS] or HT without pre-transplant MCS [HT Non-MCS]) or long-term MCS (destination therapy). We also identified factors associated with gains in QALYs through 24 months follow-up. METHODS: Of 393 eligible patients enrolled (10/1/15-12/31/18) at 13 U.S. sites, 161 underwent HT (n=68 HT MCS, n=93 HT Non-MCS) and 144 underwent long-term MCS. Survival and HRQOL data were collected through 24 months. QALY health utilities were based on patient self-report of EQ-5D-3L dimensions. Mean-restricted QALYs were compared among groups using generalized linear models. RESULTS: For the entire cohort, mean age in years closest to surgery was 67 (standard deviation, SD: 4.7), 78% were male, and 83% were White. By 18 months post-surgery, sustained significant differences in adjusted average+SD QALYs emerged across groups, with the HT Non-MCS group having the highest average QALYs (24-month window: HT Non-MCS=22.58+1.1, HT MCS=19.53+1.33, Long-term MCS=19.49+1.3, p=0.003). At 24 months post-operatively, a lower gain in QALYs was associated with HT MCS, long-term MCS, a lower pre-operative LVEF, NYHA class III or IV before surgery, and an ischemic or other etiology of HF. CONCLUSIONS: Determination of QALYs may provide important information for policy makers and clinicians to consider regarding benefits of HT and long-term MCS as treatment options for older patients with HF.

A large, multi-center survey assessing health, social support, literacy, and self-management resources in patients with heart failure.

BACKGROUND: Most patients with heart failure (HF) have multimorbidity which may cause difficulties with self-management. Understanding the resources patients draw upon to effectively manage their health is fundamental to designing new practice models to improve outcomes in HF. We describe the rationale, conceptual framework, and implementation of a multi-center survey of HF patients, characterize differences between responders and non-responders, and summarize patient characteristics and responses to the survey constructs among responders. METHODS: This was a multi-center cross-sectional survey study with linked electronic health record (EHR) data. Our survey was guided by the Chronic Care Model to understand the distribution of patient-centric factors, including health literacy, social support, self-management, and functional and mental status in patients with HF. Most questions were from existing validated questionnaires. The survey was administered to HF patients aged ≥ 30 years from 4 health systems in PCORnet® (the National Patient-Centered Clinical Research Network): Essentia Health, Intermountain Health, Mayo Clinic, and The Ohio State University. Each health system mapped their EHR data to a standardized PCORnet Common Data Model, which was used to extract demographic and clinical data on survey responders and non-responders. RESULTS: Across the 4 sites, 10,662 patients with HF were invited to participate, and 3330 completed the survey (response rate: 31%). Responders were older (74 vs. 71 years; standardized difference (95% CI): 0.18 (0.13, 0.22)), less racially diverse (3% vs. 12% non-White; standardized difference (95% CI): -0.32 (-0.36, -0.28)), and had higher prevalence of many chronic conditions than non-responders, and thus may not be representative of all HF patients. The internal reliability of the validated questionnaires in our survey was good (range of Cronbach's alpha: 0.50-0.96). Responders reported their health was generally good or fair, they frequently had cardiovascular comorbidities, > 50% had difficulty climbing stairs, and > 10% reported difficulties with bathing, preparing meals, and using transportation. Nearly 80% of patients had family or friends sit with them during a doctor visit, and 54% managed their health by themselves. Patients reported generally low perceived support for self-management related to exercise and diet. CONCLUSIONS: More than half of patients with HF managed their health by themselves. Increased understanding of self-management resources may guide the development of interventions to improve HF outcomes.

The impact of multimorbidity and functional limitation on quality of life in patients with heart failure: A multi-site study.

BACKGROUND: Multimorbidity and functional limitation are associated with poor outcomes in heart failure (HF). However, the individual and combined effect of these on health-related quality of life in patients with HF is not well understood. METHODS: Patients aged ≥30 years with two or more HF diagnostic codes and one or more HF-related prescription drugs from four U.S. institutions were mailed a survey to measure patient-centric factors including functional status (activities of daily living [ADLs]) and health-related quality of life (PROMIS-29 Health Profile). Patients with HF from January 1, 2013 to February 1, 2018 were included. Multimorbidity was defined as ≥2 non-cardiovascular comorbidities; functional limitation as any limitation in at least one of eight ADLs. Patients were categorized into four groups by multimorbidity (Yes/No) and functional limitation (Yes/No). We dichotomized the PROMIS-29 sub-scale scores at the median and calculated odd ratios for the four multimorbidity/functional limitation groups. RESULTS: A total of 3330 patients with HF returned the survey (response rate 31%); 3020 completed the questions of interest and were retained. Among these patients (45% female; mean age 73 [standard deviation: 12] years), 29% had neither multimorbidity nor functional limitation, 24% had multimorbidity only, 22% had functional limitation only, and 25% had both. After adjustment, having functional limitation only was associated with higher anxiety (odds ratio [OR]: 3.44, 95% confidence interval [CI]: 2.66-4.45), depression (OR: 3.11, 95% CI: 2.39-4.06), and fatigue (OR: 4.19, 95% CI: 3.25-5.40); worse sleep (OR: 2.14, 95% CI: 1.69-2.72) and pain (OR: 6.73, 95% CI: 5.15-8.78); and greater difficulty with social activities (OR: 9.40, 95% CI: 7.19-12.28) compared with having neither. Results were similar for having both multimorbidity and functional limitation. CONCLUSION: Patients with only functional limitation have similar poor health-related quality of life scores as those with both multimorbidity and functional limitation, underscoring the important role that physical functioning plays in the well-being of patients with HF.

A retrospective analysis of anticoagulant safety among heart transplant recipients undergoing endomyocardial biopsy.

BACKGROUND: Transvenous endomyocardial biopsy is an invasive procedure which is used to diagnose rejection following an orthotopic heart transplant. Endomyocardial biopsy is widely regarded as low risk with all-cause complication rates below 5% in most safety studies. Following transplant, some patients require therapeutic anticoagulation. It is unknown whether anticoagulation increases endomyocardial biopsy bleeding risk. METHODS: Records from 2061 endomyocardial biopsies performed for post-transplant rejection surveillance at our institution between November 2016 and August 2022 were reviewed. Bleeding complications were defined as vascular access-related hematoma or bleeding, procedure-related red blood cell transfusion, and new pericardial effusion. Relative risk and small sample-adjusted 95% confidence interval was calculated to investigate the association between bleeding complications and anticoagulation. RESULTS AND CONCLUSIONS: The overall risk of bleeding was 1.2% (25/2061 cases). There was a statistically significant increase in bleeding among patients on intravenous (RR 4.46, CI 1.09-18.32) but not oral anticoagulants (RR .62, CI .15-2.63) compared to patients without anticoagulant exposure. There was a trend toward increased bleeding among patients taking warfarin with INR ≥ 1.8 (RR 3.74, CI .90-15.43). Importantly, no bleeding events occurred in patients taking direct oral anticoagulants such as apixaban. Based on these results, intravenous rather than oral anticoagulation was associated with a significantly higher risk of bleeding complications following endomyocardial biopsy.

Textbook outcome: A novel metric in heart transplantation outcomes.

OBJECTIVE: Assessing heart transplant program quality using short-term survival is insufficient. We define and validate the composite metric textbook outcome and examine its association with overall survival. METHODS: We identified all primary, isolated adult heart transplants in the United Network for Organ Sharing/Organ Procurement and Transplantation Network Standard Transplant Analysis and Research files from May 1, 2005, to December 31, 2017. Textbook outcome was defined as length of stay 30 days or less; ejection fraction greater than 50% during 1-year follow-up; functional status 80% to 100% at 1 year; freedom from acute rejection, dialysis, and stroke during the index hospitalization; and freedom from graft failure, dialysis, rejection, retransplantation, and mortality during the first year post-transplant. Univariate and multivariate analyses were performed. Factors independently associated with textbook outcome were used to create a predictive nomogram. Conditional survival at 1 year was measured. RESULTS: A total of 24,620 patients were identified with 11,169 (45.4%, 95% confidence interval, 44.7-46.0) experiencing textbook outcome. Patients with textbook outcome were more likely free from preoperative mechanical support (odds ratio, 3.504, 95% confidence interval, 2.766 to 4.439, P < .001), free from preoperative dialysis (odds ratio, 2.295, 95% confidence interval, 1.868-2.819, P < .001), to be not hospitalized (odds ratio, 1.264, 95% confidence interval, 1.183-1.349, P < .001), to be nondiabetic (odds ratio, 1.187, 95% confidence interval, 1.113-1.266, P < .001), and to be nonsmokers (odds ratio, 1.160, 95% confidence interval,1.097-1.228, P < .001). Patients with textbook outcome have improved long-term survival relative to patients without textbook outcome who survive at least 1 year (hazard ratio for death, 0.547, 95% confidence interval, 0.504-0.593, P < .001). CONCLUSIONS: Textbook outcome is an alternative means of examining heart transplant outcomes and is associated with long-term survival. The use of textbook outcome as an adjunctive metric provides a holistic view of patient and center outcomes.

Novel uses for implanted haemodynamic monitoring in adults with subaortic right ventricles.

BACKGROUND: Pulmonary hypertension (PH) is a common complication in patients with complete dextro-transposition of the great arteries (TGA) after atrial switch (D-TGA/AS) and congenitally corrected TGA (ccTGA). In this population with subaortic right ventricles (sRVs), echocardiography is a poor screening tool for PH; implantable invasive haemodynamic monitoring (IHM) could be used for this purpose, but data are limited. The aim of this study is to report on novel uses of IHM in patients with sRV. METHODS: This retrospective study describes the uses of IHM, impact of IHM on heart failure hospitalisation (HFH) and device-related complications in adults with sRV from a single centre (2015-2022). RESULTS: IHM was placed in 18 patients with sRV (median age 43 (range 30-54) years, 8 female, 16 with D-TGA/AS, 2 with ccTGA); 16 had moderate or severe sRV systolic dysfunction, 13 had PH on catheterisation. IHM was used for (1) Medical therapy titration, (2) Medical management after ventricular assist device in patients with transplant-limiting PH and (3) Serial monitoring of pulmonary artery pressures without repeat catheterisations to help identify the optimal time for heart transplant referral. In follow-up (median 23 months), HFHs/year were similar to the year prior to IHM (median 0 (IQR 0-1.0) before vs 0 (0-0.8) after, p=0.984). Device migration occurred in one, without long-term sequelae. CONCLUSIONS: Uses of IHM in patients with sRV are described which may minimise the need for serial catheterisations in a population where PH is prevalent. HFHs were low overall but not impacted by IHM. One device-related complication occurred without long-term consequence.

Emergency department patient and physician survey accuracy compared to chart abstraction in patients with acute respiratory illness.

BACKGROUND: High-quality research studies in older adults are needed. Unfortunately, the accuracy of chart review data in older adult patients has been called into question by previous studies. Little is known on this topic in patients with suspected pneumonia, a disease with 500,000 annual older adult U.S. emergency department (ED) visits that presents a diagnostic challenge to ED physicians. The study objective was to compare direct interview and chart abstraction as data sources. METHODS: We present a preplanned secondary analysis of a prospective, observational cohort of ED patients ≥65 years of age with suspected pneumonia in two Midwest EDs. We describe the agreement between chart review and a criterion standard of prospective direct patient survey (symptoms) or direct physician survey (examination findings). Data were collected by chart review and from the patient and treating physician by survey. RESULTS: The larger study enrolled 135 older adults; 134 with complete symptom data and 129 with complete examination data were included in this analysis. Pneumonia symptoms (confusion, malaise, rapid breathing, any cough, new/worse cough, any sputum production, change to sputum) had agreement between patient/legally authorized representative survey and chart review ranging from 47.8% (malaise) to 80.6% (confusion). All examination findings (rales, rhonchi, wheeze) had percent agreement between physician survey and chart review of ≥80%. However, all kappas except wheezing were less than 0.60, indicating weak agreement. CONCLUSIONS: Both patient symptoms and examination findings demonstrated discrepancies between chart review and direct survey with larger discrepancies in symptoms reported. Researchers should consider these potential discrepancies during study design and data interpretation.

Change in Caregiver Health-Related Quality of Life From Before to Early After Surgery: SUSTAIN-IT Study.

BACKGROUND: Information about health-related quality of life (HRQOL) among caregivers of older patients with heart failure who receive heart transplantation (HT) and mechanical circulatory support (MCS) is sparse. We describe differences and factors associated with change in HRQOL before and early post-surgery among caregivers of older heart failure patients who underwent 3 surgical therapies: HT with pretransplant MCS (HT MCS), HT without pretransplant MCS (HT non-MCS), and long-term MCS. METHODS: Caregivers of older patients (60-80 years) from 13 US sites completed the EQ-5D-3 L visual analog scale (0 [worst]-100 [best] imaginable health state) and dimensions before and 3 and 6 months post-surgery. Analyses included linear regression, t tests, and nonparametric tests. RESULTS: Among 227 caregivers (HT MCS=54, HT non-MCS=76, long-term MCS=97; median age 62.7 years, 30% male, 84% White, 83% spouse/partner), EQ-5D visual analog scale scores were high before (84.8±14.1) and at 3 (84.7±13.0) and 6 (83.9±14.7) months post-surgery, without significant differences among groups or changes over time. Patient pulmonary hypertension presurgery (ß=-13.72 [95% CI, -21.07 to -6.36]; P<0.001) and arrhythmia from 3 to 6 months post-operatively (ß=-14.22 [95% CI, -27.41 to -1.02]; P=0.035) were associated with the largest decrements in caregiver HRQOL; patient marital/partner status (ß=6.21 [95% CI, 1.34-11.08]; P=0.013) and presurgery coronary disease (ß=8.98 [95% CI, 4.07-13.89]; P<0.001) were associated with the largest improvements. CONCLUSIONS: Caregivers of older patients undergoing heart failure surgeries reported overall high HRQOL before and early post-surgery. Understanding factors associated with caregiver HRQOL may inform decision-making and support needs. REGISTRATION: URL: https://www. CLINICALTRIALS: gov; Unique identifier: NCT02568930.

Caregiver burden before heart transplantation and long-term mechanical circulatory support: Findings from the sustaining quality of life of the aged: Transplant or mechanical support (SUSTAIN-IT) study.

BACKGROUND: Caregiving for heart failure (HF) patients is burdensome. We examined differences in caregiver burden for 3 groups of older advanced HF patients: (1) supported with mechanical circulatory support (MCS) before heart transplantation (HT MCS), (2) awaiting transplant without MCS (HT non-MCS), and (3) prior to long-term MCS and factors associated with burden. METHOD: From October 1, 2015 to December 31, 2018, we enrolled 276 caregivers for HF patients from 13 U.S. sites: 85 HT MCS, 96 HT non-MCS, and 95 prior to long-term MCS. At enrollment, caregivers completed the Oberst Caregiving Burden Scale (15 items, 2 subscales: time (range = 1-5; higher score = more time spent on task) and difficulty (range = 1-5; higher score = higher difficulty of task) and other measures. Statistical analyses included descriptive statistics, ANOVA, chi-square tests, and linear regression. RESULT: Overall, caregivers were aged 60.8 ± 9.8 years and predominantly white, female, spouses, well educated, and reported ≥1 comorbidities. Caregivers overall reported a moderate amount of time spent on tasks and slight task difficulty. Caregivers for HT non-MCS candidates reported significantly less perceived time spent on tasks than caregivers for HT MCS candidates and caregivers for patients prior to long-term MCS (2.2 ± 0.74 vs 2.4 ± 0.74 vs 2.5 ± 0.71, respectively, p = 0.02) and less perceived difficulty of tasks (1.2 ± 0.33 vs 1.4 ± 0.53 vs 1.4 ± 0.54, respectively, p = 0.01). Caregiver and patient factors were associated with caregiver burden. CONCLUSIONS: Prior to HT and long-term MCS, caregiver burden was low to moderate. Caregiver factors were predominantly associated with caregiver burden. Understanding caregiver burden and factors affecting caregiver burden may enhance preoperative advanced therapies discussions and guide caregiver support.

Total artificial heart implantation: supportive care preparedness planning framework.

BACKGROUND: The total artificial heart (TAH) is an implanted device approved as a modality to stabilize patients with severe biventricular heart failure or persistent ventricular arrhythmias for evaluation and bridge to transplantation. According to the Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS), about 450 patients received a TAH between 2006 and 2018. Patients being evaluated for a TAH are often critically ill and a TAH offers the best chance at survival. Given the prognostic uncertainty of these patients, there is a crucial need for preparedness planning to help patients and their caregivers plan for living and supporting a loved one with a TAH. AIM: To describe an approach to preparedness planning and highlight the importance of palliative care. METHODS: We reviewed the current needs and approaches to preparedness planning for a TAH. We categorized our findings and suggest a guide to maximize conversations with patients and their decision makers. RESULTS: We identified four critical areas to address: the decision maker, minimal acceptable outcome/maximal acceptable burden, living with the device, and dying with the device. We suggest using a framework of mental and physical outcomes and locations of care as a way to identify minimal acceptable outcome and maximal acceptable burden. CONCLUSION: Decision making for a TAH is complex. There is an urgency and patients do not always have capacity. Identifying legal decision makers and social support is critical. The surrogate decision makers should be included in preparedness planning including discussions about end-of-life care and treatment discontinuation. Having palliative care as members of the interdisciplinary mechanical circulatory support team can assist in these preparedness conversations.

Prevalence of Violence against Providers in Heart and Lung Transplant Programs.

Workplace violence in healthcare institutions is becoming more frequent. The objective of this study was to better understand the nature of threat and physical acts of violence from heart and lung transplant patients and families toward healthcare providers and suggest programmatic mitigation strategies. We administered a brief survey to attendees at the 2022 International Society of Heart and Lung Transplantation Conference in Boston, Massachusetts. A total of 108 participants responded. Threats of physical violence were reported by forty-five participants (42%), were more frequently reported by nurses and advanced practice providers than physicians (67% and 75% vs. 34%; p < 0.001) and were more prevalent in the United States than abroad (49% vs. 21%; p = 0.026). Acts of physical violence were reported by one out of every eight providers. Violence against providers in transplant programs warrants closer review by health systems in order to ensure the safety of team members.

Impact of Temporary Preoperative Mechanical Support on Heart Transplant Outcomes.

We sought to assess the impact of temporary preoperative mechanical circulatory support (TPMCS) on heart transplantation outcomes. A total of 4,060 adult heart transplants from June 1, 2006, to December 31, 2019, were identified in the Scientific Registry of Transplant Recipients database as having TPMCS. Recipients were divided into groups based on their type of TPMCS: intra-aortic balloon pump (IABP), temporary ventricular assist device (VAD), biventricular assist device (BIVAD), and extracorporeal membrane oxygenation (ECMO). Perioperative outcomes and survival were compared among groups. Recipients with IABP were associated with older age, a smoking history, and a significantly shorter wait list time ( p < 0.01). Recipients with ECMO had a significantly increased in-hospital mortality as well as an increased incidence of dialysis ( p < 0.01). Kaplan-Meier analysis revealed worse 1 and 5 year survival for recipients with ECMO. Cox model demonstrated a significantly increased risk of mortality with BIVAD (hazard ratio [HR], 1.33; 95% CI, 1.12-1.57; p < 0.01) and ECMO (HR, 1.64; 95% CI, 1.33-2.03; p < 0.01). While patients with IABP have a survival comparable to patients without TPMCS or durable left VAD, outcomes for BIVADs and ECMO are not as favorable. Transplantation centers must continue to make careful choices about the type of TPMCS utilized before heart transplant.

Allocation changes in heart transplantation: What has really changed?

OBJECTIVE: In 2018, the heart allocation system changed status classifications and broadened geographic distribution. We examined this change at a national level based on the immediate pre- and postchange periods. METHODS: Using the Scientific Registry of Transplant Recipients database, we identified all adult primary, isolated heart transplants from October 18, 2017, to October 17, 2019. Two time periods were compared: (1) October 18, 2017, to October 17, 2018 (pre); and (2) October 18, 2018, to October 17, 2019 (post). Comparisons were made between groups, and a multivariable logistic regression model was created to identify factors associated with pretransplant temporary mechanical circulatory support. Volume analysis at the regional, state, and center level was also conducted as the primary focus. RESULTS: A total of 5381 independent heart transplants were identified within the time frame. On unadjusted analysis, there was a significant increase in temporary mechanical circulatory support (pre, 11.1%; post, 36.2%, P < .01) and decrease in waitlist days (pre, 93 days; post, 41 days; P < .01). Distance traveled (nautical miles) (pre, 83; post, 225; P < .01) and ischemic time (hours) (pre, 3.0; post, 3.4; P < .01) were significantly increased. On multivariable analysis, the postallocation time period was independently associated with temporary MCS (odds ratio, 4.463; 95% confidence interval, 3.844-5.183; P < .001). Transplant volumes did not significantly change after the allocation change at a regional, state, and center level. CONCLUSIONS: Since the planned alteration to the allocation system, there have been changes in the use of temporary mechanical circulatory support as well as distance and ischemic time associated with transplant, but no significant volume changes were observed. Continued observation of outcomes and volume under the new allocation system will be necessary in the upcoming years.

Thoracic retransplantation: Does time to retransplantation matter?

OBJECTIVE: For some individuals, chronic allograft failure is best treated with retransplantation. We sought to determine if time to retransplantation impacts short- and long-term outcomes for heart or lung retransplant recipients with a time to retransplantation more than 1 year. METHODS: The United Network for Organ Sharing/Organ Procurement and Transplantation Network STAR file was queried for all adult, first-time heart (June 1, 2006, to September 30, 2020) and lung (May 1, 2005, to September 30, 2020) retransplantations with a time to retransplantation of at least 1 year. Patients were grouped according to the tertile of time to retransplantation (tertile 1: 1-7.7 years, tertile 2: 7.7-14.7 years, tertile 3: 14.7+ years; lung: tertile 1: 1-2.8 years, tertile 2: 2.8-5.6 years, tertile 3: 5.6+ years). The primary outcome was survival after retransplantation. Comparative statistics identified differences in groups, and Kaplan-Meier methods and a Cox proportional hazard model were used for survival analysis. RESULTS: After selection, 908 heart and 871 lung retransplants were identified. Among heart retransplant recipients, tertile 1 was associated with male sex, smoking history, higher listing status, and increased mechanical support pretransplant. Tertile 3 had the highest rate of concomitant kidney transplant; however, the incidence of morbidity and in-hospital mortality was similar among the groups. Unadjusted and adjusted analyses revealed no survival difference among all groups. Regarding lung retransplant recipients, tertile 1 was associated with increased lung allocation score, pretransplant hospitalization, and mechanical support. Unadjusted and adjusted survival analyses revealed decreased survival in tertile 1. CONCLUSIONS: Time to retransplant does not appear to affect heart recipients with a time to retransplantation of more than 1 year; however, shorter time to retransplantation for prior lung recipients is associated with decreased survival. Potential lung retransplant candidates with a time to retransplantation of less than 2.8 years should be carefully evaluated before retransplantation.

Disparities in heart transplantation.

PURPOSE OF REVIEW: Heart transplantation remains the gold standard therapy for end stage heart failure, but barriers remain, preventing equitable access to and affecting outcomes following transplantation. The objective of this review is to summarize current and historical literature on the disparities that persist, and to highlight the gaps in evidence for further investigation. RECENT FINDINGS: Although progress has been made to increase the rates of advanced heart failure therapies to racial/ethnic minority populations and those with lower socioeconomic status, differential access and outcomes remain. The disparities that persist are categorized by patient demographics, social influences, geopolitical factors, and provider bias. SUMMARY: Disparities in heart transplantation exist, which span a wide spectrum. Healthcare professionals need to be cognizant of these disparities that patients face in terms of access to and outcomes for heart transplantation. Further research and system changes are needed to make heart transplantation a fairer option for patients of varying backgrounds with end stage heart failure.

Health-Related Quality of Life in Older Patients With Heart Failure From Before to Early After Advanced Surgical Therapies: Findings From the SUSTAIN-IT Study.

BACKGROUND: Restoring health-related quality of life (HRQOL) is a therapeutic goal for older patients with advanced heart failure. We aimed to describe change in HRQOL in older patients (60-80 years) awaiting heart transplantation (HT) with or without pretransplant mechanical circulatory support (MCS) or scheduled for long-term MCS, if ineligible for HT, from before to 6 months after these surgeries and identify factors associated with change. METHODS: Patients from 13 US sites completed the EuroQol 5-dimension 3L questionnaire and Kansas City Cardiomyopathy Questionnaire-12 at baseline and 3 and 6 months after HT or long-term MCS. Analyses included univariate comparisons and multivariable linear regression. RESULTS: Among 305 participants (cohort mean age=66.2±4.7 years, 78% male, 84% White, 55% New York Heart Association class IV), 161 underwent HT (n=68 with and n=93 without pretransplant MCS), and 144 received long-term MCS. From baseline to 3 months, EuroQol 5-dimension visual analog scale scores improved in HT patients without pretransplant MCS (54.5±24.3 versus 75.9±16.0, P<0.001) and long-term MCS patients (45.7±22.9 versus 66.2± 20.9, P <0.001); while Kansas City Cardiomyopathy Questionnaire-12 overall summary scores improved in all 3 groups (HT without pretransplant MCS: 47.2±20.9 versus 77.4±20.1, P <0.001; long-term MCS: 35.3±20.2 versus 58.6±22.0, P <0.001; and HT with pretransplant MCS: 58.3±23.6 versus 72.1±23.5, P=0.002). No further HRQOL improvement was found from 3 to 6 months. Factors most significantly associated with change in HRQOL, baseline 3 months, were right heart failure and 3-month New York Heart Association class, and 3 to 6 months, were 6-month New York Heart Association class and major bleeding. CONCLUSIONS: In older heart failure patients, HRQOL improved from before to early after HT and long-term MCS. At 6 postoperative months, HRQOL of long-term MCS patients was lower than one or both HT groups. Understanding change in HRQOL from before to early after these surgeries may enhance decision-making and guide patient care. REGISTRATION: URL: https://www.

Approaches and strategies to manage the hepatitis C virus-positive heart donor.

PURPOSE OF REVIEW: Cardiac transplantation remains the treatment of choice for patients with advanced heart failure, but is limited by a donor organ shortage. Utilization of hepatitis C virus (HCV)-positive donors has been recently adopted to expand access to heart transplantation. We review the history of HCV heart transplantation, modern drug therapy, and recent outcomes. RECENT FINDINGS: Since the advent of direct-acting antiviral (DAA) therapy, several single-center studies, and retrospective reviews have demonstrated good short-term outcomes, shorter waitlist times, and clearance of viremia with recipients of HCV-positive hearts. Two principle approaches to treatment of recipients of HCV viremic donors are utilized. In the prophylactic strategy, therapy is initiated before viremia is detected compared with the preemptive approach where initiation of DAA is delayed until after viremia is detected. Future studies are needed to address uncertainty about medium and long-term outcomes of using HCV-positive hearts and to determine the optimal treatment timing and duration. SUMMARY: Utilization of HCV-positive donors has expanded the heart donor pool and appears safe through the early posttransplant period. We suggest that prophylactic administration of the shortest effective course of a DAA pangenotypic agent should be the current standard of care.

Heart Failure in Older Adults: Medical Management and Advanced Therapies.

As the population ages and the prevalence of heart failure increases, cardiologists and geriatricians can expect to see more elderly patients with heart failure in their everyday practice. With the advancement of medical care and technology, the options for heart failure management have expanded, though current guidelines are based on studies of younger populations, and the evidence in older populations is not as robust. Pharmacologic therapy remains the cornerstone of heart failure management and has improved long-term mortality. Prevention of sudden cardiac death with implantable devices is being more readily utilized in older patients. Advanced therapies have provided more options for end-stage heart failure, though its use is still limited in older patients. In this review, we discuss the current guidelines for medical management of heart failure in older adults, as well as the expanding literature on advanced therapies, such as heart transplantation in older patients with end-stage heart failure. We also discuss the importance of a multidisciplinary care approach including consideration of non-medical co-morbidities such as frailty and cognitive decline.
