Abstract
PURPOSE Cardiac disease results in significant morbidity and mortality in patients with muscular dystrophy (MD). Single centers have reported their ventricular assist device (VAD) experience in specific MDs and in limited numbers. This study sought to describe the outcomes associated with VAD therapy in an unselected population across multiple centers. METHODS We examined outcomes of patients with MD and dilated cardiomyopathy implanted with a VAD at Advanced Cardiac Therapies Improving Outcomes Network (ACTION) centers from 9/2012 to 9/2020. RESULTS A total of 19 VADs were implanted in 18 patients across 12 sites. The majority of patients had dystrophinopathy (66%) and the median age at implant was 17.2 years (range 11.7-29.5). Eleven patients were non-ambulatory (61%) and 6 (33%) were on respiratory support pre-VAD. Five (28%) patients were implanted as a bridge to transplant, 4 of whom survived to transplant. Of 13 patients implanted as bridge to decision or destination therapy, 77% were alive at 1 year and 69% at 2 years. The overall frequencies of positive outcome (transplanted or alive on device) at 1 year and 2 years were 84% and 78%, respectively. Two patients suffered a stroke, 2 developed sepsis, 1 required tracheostomy, and 1 experienced severe right heart failure requiring right-sided VAD. CONCLUSIONS This study demonstrates the potential utility of VAD therapies in patients with muscular dystrophy. Further research is needed to further improve outcomes and better determine which patients may benefit most from VAD therapy in terms of survival and quality of life.

Abstract
Duchenne muscular dystrophy (DMD) is the most common form of childhood muscular dystrophy resulting in progressive muscle wasting and weakness. With advancements in respiratory care and the use of glucocorticoids, cardiomyopathy has surpassed respiratory compromise as the leading cause of morbidity and mortality in this patient population. As muscular dystrophy remains a relative contraindication to heart transplantation, end-stage heart failure management represents a major therapeutic challenge. Long-term left ventricular assist device (LVAD) therapy has emerged as a promising management strategy to improve the survival and quality of life in DMD cardiomyopathy. Preoperative planning, optimal patient selection, aggressive postoperative rehabilitation, and continued discussion of goals of care are critical considerations for the appropriate use of LVAD in DMD patients with cardiomyopathy.

Abstract
Patients with Duchenne muscular dystrophy suffer debilitating muscle destruction, resulting in loss of ambulation, diminished respiratory function, gastrointestinal disturbances and cardiomyopathy. Although it is the most common cause of death in these patients, cardiomyopathy is poorly understood in terms of distinct pathogenesis, natural history, and specific, effective therapeutic interventions. We review the state-of-the-art knowledge of Duchenne muscular dystrophy-associated cardiomyopathy including clinical evaluation, imaging, medical and perioperative management, and prospects for gene therapy. We also review cardiomyopathy in heterozygote carriers. By describing our current understanding and best practices, we hope to improve harmonization of care across institutions and identify collective knowledge gaps to guide future research efforts.

Abstract
This article addresses the pathophysiology, diagnostic approaches, and therapeutic options in the more common forms of muscular dystrophy, especially those seen in pediatric and young adult populations. The major emphasis is on the dystrophinopathies because their treatment options are templates for those used in various other forms of dystrophy. Most patients with cardiomyopathy are treated with angiotensin-converting enzyme inhibitors or angiotensin receptor blockers, with other agents added as the disease progresses. Destination therapies and transplantation options are mentioned where appropriate. Some dystrophies can have significant conduction abnormalities requiring pacemaker treatment. Others with ventricular tachydysrhythmias may necessitate internal cardiac defibrillator placement.

Abstract
BACKGROUND Steroid use has prolonged ambulation in Duchenne muscular dystrophy (DMD) and combined with advances in respiratory care overall management has improved such that cardiac manifestations have become the major cause of death. Unfortunately, there is no consensus for DMD-associated cardiac disease management. Our purpose was to assess effects of steroid use alone or in combination with angiotensin converting enzyme inhibitors (ACEI) or angiotension receptor blocker (ARB) on cardiovascular magnetic resonance (CMR) derived circumferential strain (εcc). METHODS We used CMR to assess effects of corticosteroids alone (Group A) or in combination with ACEI or ARB (Group B) on heart rate (HR), left ventricular ejection fraction (LVEF), mass (LVM), end diastolic volume (LVEDV) and circumferential strain (εcc) in a cohort of 171 DMD patients >5 years of age. Treatment decisions were made independently by physicians at both our institution and referral centers and not based on CMR results. RESULTS Patients in Group A (114 studies) were younger than those in Group B (92 studies)(10 ± 2.4 vs. 12.4 ± 3.2 years, p < 0.0001), but HR, LVEF, LVEDV and LVM were not different. Although εcc magnitude was lower in Group B than Group A (-13.8 ± 1.9 vs. -12.8 ± 2.0, p = 0.0004), age correction using covariance analysis eliminated this effect. In a subset of patients who underwent serial CMR exams with an inter-study time of ~15 months, εcc worsened regardless of treatment group. CONCLUSIONS These results support the need for prospective clinical trials to identify more effective treatment regimens for DMD associated cardiac disease.

Abstract
The management of heart failure in children is becoming a specialized discipline within pediatric cardiology. Unlike the treatment of heart failure in adults, for which an extensive body of literature supports current treatment regimens, management of heart failure in children is largely guided by extrapolation from adult studies and expert opinion. This review focuses on the current state-of-the-art with respect to the outpatient management of heart failure in children.

Abstract
Myopathies are frequently not confined to the skeletal muscles but also involve other organs or tissues. One of the most frequently affected organ in addition to the skeletal muscle is the heart (cardiac involvement, CI). CI manifests as impulse generation or conduction defects, focal or diffuse myocardial thickening, dilation of the cardiac cavities, relaxation abnormality, hypertrophic, dilated, restrictive cardiomyopathy, apical form of hypertrophic cardiomyopathy, noncompaction, Takotsubo phenomenon, secondary valve insufficiency, intra-cardiac thrombus formation, or heart failure with systolic or diastolic dysfunction. CI occurs in dystrophinopathies, Emery-Dreifuss muscular dystrophy, facioscapulohumeral muscular dystrophy, limb girdle muscular dystrophies, laminopathies, congenital muscular dystrophies, myotonic dystrophies, congenital myopathies, metabolic myopathies, desminopathies, myofibrillar myopathy, Barth syndrome, McLeod syndrome, Senger's syndrome, and Bethlem myopathy. Patients with myopathy should be cardiologically investigated as soon as their neurological diagnosis is established, since supportive cardiac therapy is available, which markedly influences prognosis and outcome of CI in these patients.
