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

Effects of Beta Blockers and ACE Inhibitors after Left Ventricular Assist Device Implantation

Purpose: While Beta blockers(BB) and Angiotensin system blockers(ACEinh/ARB) are important components in advanced heart failure therapy, their use after left ventricular assist device (LVAD) implantation remains controversial. Concern has been raised about possible adverse effects of BB on right ventricular(RV) function while tolerance and efficacy/outcome data for ACEinh are lacking. This study aimed to characterize the use of medical therapy post-LVAD implantation and to evaluate its safety and efficacy. Methods: Demographic, clinical and echocardiographic variables of patients implanted with a continuous-flow LVAD between 2012 and 2015 at a single center were retrospectively reviewed. Mortality and heart failure(CHF) hospitalizations were followed from 6-18 months’ post-implant. Results: Of a total of 98 patients, the mean age was 57 years, 81% were men and 61% had ischemic disease. While the use of diuretics decreased considerably post LVAD, over 50% continued to require diuretics. At 6th month post-implantation, 73% of patients were on BB, and these patients had significantly lower proBNP at 6 and 12 months follow up. Despite significant prevalence of RV dysfunction in the cohort (\u3e75% at 6 months), there was no significant difference in CHF hospitalizations based on BB use (14% vs 15%) and instead a trend towards less deaths in those on BB (6% vs 15%). ACEinh/ARB use was likewise common at 6 month (61%) and these patients had lower proBNP at 6 and 12 months, lower right atrial(RA) pressures (9 vs 12 mmHg, p=0.03), and a significantly lower mortality—a finding which remained on multivariate analysis. Conclusion: The use of ACEinh/ARB appeared to be associated with subsequent improved survival, lower proBNP and RA pressures. The use of BB post-LVAD appears safe and was associated with a lower proBNP, even in a patient population with a significant prevalence of RV dysfunction

Giant-cell myocarditis management using short-term TandemHeart support, MANTA closure device, and combination immunosuppression.

We present the case of a 53-year-old woman who presented to the hospital with palpitations and fatigue. The workup revealed new-onset systolic heart failure secondary to giant cell myocarditis. She developed cardiogenic shock, which was managed with the TandemHeart left ventricular assist device and combination immunosuppression strategy. This article highlights our management approach that avoided the need for an urgent heart transplant

Persistent mitral regurgitation after left ventricular assist device: a clinical conundrum

Aims: Persistent mitral valve regurgitation (MR) after continuous flow left ventricular assist device implantation (cfLVAD) is associated with pulmonary hypertension and right ventricular failure with variable effects on survival across published studies. The aim of this study is to determine the incidence and predictors of persistent MR at 6-month follow-up after cfLVAD implantation and its impact on survival, haemodynamics, right ventricular function, and morbidity. Methods and results: We performed a retrospective review of all adult cfLVAD recipients from January 2012 to June 2017 at a single tertiary university hospital with follow-up until April 2019. Primary outcome was to compare survival between patients with no-to-mild compared with persistent moderate-to-severe MR at 6 months. Secondary outcomes included right heart failure (RHF), length of stay, re-hospitalizations, and composite of death, transplant, and pump exchange during the length of follow-up. Final analytic sample was 111 patients. The incidence of persistent moderate or severe MR at 6 months was 26%. Significant predictors of persistent MR at 6 months were left atrium dimension and volume. The group with persistent moderate-to-severe MR at 6 months had higher incidence of RHF at 6 months (45% vs. 25%, P = 0.04). There was no difference in survival at 1 year between the groups (no-to-mild MR 85.5%, moderate-to-severe MR 87.9%, Wilcoxon P-value = 0.63). There was no difference in re-hospitalizations, length of stay, composite of death, transplant, or pump exchange during the length of follow-up between the comparison groups. Conclusions: Persistent moderate-to-severe MR after cfLVAD implantation is present in one fourth of patients and is associated with increased incidence of RHF, higher mean pulmonary pressure, and pulmonary capillary wedge pressure with no effect on 1 year survival. Increased left atrium size was associated with persistent moderate-to-severe MR at 6 months.Open access journalThis item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.

A Phase I, Single Ascending Dose Study of Cimaglermin Alfa (Neuregulin 1β3) in Patients With Systolic Dysfunction and Heart Failure.

A first-in-human, phase 1, double blind, placebo-controlled, single ascending dose study examined the safety, tolerability, and exploratory efficacy of intravenous infusion of a recombinant growth factor, cimaglermin alfa, in patients with heart failure and left ventricular systolic dysfunction (LVSD). In these patients on optimal guideline-directed medical therapy, cimaglermin treatment was generally tolerated except for transient nausea and headache and a dose-limiting toxicity was noted at the highest planned dose. There was a dose-dependent improvement in left ventricular ejection fraction lasting 90 days following infusion. Thus, cimaglermin is a potential therapy to enhance cardiac function in LVSD and warrants further investigation
