Total Artificial Heart Technology: Where Are We Now?

AbstractPurpose of ReviewThe intended goal of this paper is to review current indications, available devices, and future directions of total artificial heart therapies. Throughout the paper, we sought to help clinicians identify appropriate patients who might be considered for total artificial heart therapy, highlighting the most current data regarding outcomes and adverse events.Recent FindingsThe INTERMACS report on the total artificial heart has recently been published in theJournal of Heart and Lung Transplantation and represents the largest study to date on available TAH therapies. Notable findings include better outcomes at experienced centers, likely a result of appropriate patient selection, timing, and management of device therapy.SummaryThere are multiple new types of total artificial hearts under development. Having learned from prior experience, and with increasing use and standardization of peri- and post-operative management, there is hope of ongoing success in improving care for those with advanced heart disease and biventricular failure with the use of this technology.

Veno-arterial extracorporeal membrane oxygenation (V-A ECMO) is established therapy for short-term circulatory support for children with life-treating cardiorespiratory dysfunction. In children with congenital heart disease (CHD), ECMO is commonly used to support patients with post-cardiotomy shock or complications including intractable arrhythmias, cardiac arrest, and acute respiratory failure. Cannulation configurations include central, when the right atrium and aorta are utilized in patients with recent sternotomy, or peripheral, when cannulation of the neck or femoral vessels are used in nonoperative patients.

In this study, we determine whether transient reintroduction of embryonic stem cell cycle miR-294 promotes cardiomyocyte cell cycle reentry enhancing cardiac repair after myocardial injury. A doxycycline-inducible AAV9-miR-294 vector was delivered to mice for activating miR-294 in myocytes for 14 days continuously after myocardial infarction. miR-294-treated mice significantly improved left ventricular functions together with decreased infarct size and apoptosis 8 weeks after MI. Myocyte cell cycle reentry increased in miR-294 hearts parallel to increased small myocyte number in the heart. Isolated adult myocytes from miR-...

The European Pediatric PVD Network (EPPVDN) is a registered, non-profit organization that strives to define and develop effective, innovative diagnostic methods and treatment options in all forms of pediatric pulmonary hypertensive vascular disease, including pulmonary hypertension (PH) associated with bronchopulmonary dysplasia (BPD), PH associated with congenital heart disease (CHD), persistent PH of the newborn (PPHN), and related cardiac dysfunction. The executive writing group (EWG) members conducted searches of the PubMed/MEDLINE bibliographic database (1990-2018), held face-to-face and web-based meetings.

In this study, a significant (30%) increase in maximum lifespan of mice was found after nonablative transplantation of 100 million nucleated bone marrow (BM) cells from young donors, initiated at the age that is equivalent to 75 years for humans. Moreover, rejuvenation was accompanied by a high degree of BM chimerism for the nonablative approach. Six months after the transplantation, 28% of recipients' BM cells were of donor origin. The relatively high chimerism efficiency that we found is most likely due to the advanced age of our recipients having a depleted BM pool. In addition to the higher incorporation rates, ...

This study shows that mRNA levels of the aging related lamin A splice variant progerin, associated with premature aging in HGPS, were significantly upregulated in subjects with BMI ≥ 25 kg/m2. Moreover, our data revealed a significantly positive correlation of BMI with progerin mRNA. These data provide to our knowledge for the first-time evidence for a possible involvement of progerin in previously observed accelerated aging of overweight and obese individuals potentially limiting their longevity. Our results also showed that progerin mRNA was positively correlated with C-reactive protein (CRP). This might suggest an as...

Cytomegalovirus (CMV) is a betaherpesvirus, the impacts of which are well known to clinicians providing post-transplant cystic fibrosis care. Lung transplant recipients have the highest risk of any solid-organ transplant for CMV reactivation and ganciclovir resistance [1, 2]. Furthermore, CMV reactivation increases the risk of chronic lung allograft dysfunction. However, even in general populations, CMV seropositivity is associated with adverse outcomes including cognitive impairment, frailty, heart disease and all-cause mortality [3–5]. How CMV may contribute to disease is not evident but many streams of evidence su...
