Heart Transplantation Outcomes for Fontan Patients When Using Contemporary Strategies: Heart-Liver Transplantation and Ventricular Assist Device Therapy.
World J Pediatr Congenit Heart Surg
January 2025
The Heart Institute, Cincinnati Children's Hospital Medical Center, Cincinnati, OH, USA.
Background: With an increasing number of Fontan patients surviving into adulthood, the burden of end-stage heart failure is increasing. Prior studies have reported suboptimal heart transplantation (HTx) outcomes. Therefore, the authors describe their institutional experience of HTx in patients with Fontan circulation failure, including heart-liver transplantation (HLTx) and pretransplant systemic ventricular assist device (SVAD) therapies.

Objective: Evaluate the relationship of cathepsin-D (CD) on disease severity and clinical outcomes for women with peripartum cardiomyopathy.
Background: Cathepsin-D is a protease released during oxidative stress that cleaves prolactin (PRL) generating a 16 kDa fragment that is pro-apoptotic, anti-angiogenic, and has been implicated in the pathogenesis of peripartum cardiomyopathy (PPCM).
Methods: In 99 women with newly diagnosed PPCM enrolled in the Investigation in Pregnancy Associated Cardiomyopathy (IPAC) study, CD levels were assessed by ELISA from serum obtained at study entry.

Pump is a vital component for expelling the perfusate in small animal isolated organ normothermic machine perfusion (NMP) systems whose flexible structure and rhythmic contraction play a crucial role in maintaining perfusion system homeostasis. However, the continuous extrusion forming with the rigid stationary shaft of the peristaltic pumps can damage cells, leading to metabolic disorders and eventual dysfunction of transplanted organs. Here, we developed a novel biomimetic blood-gas system (BBGs) for preventing cell damage.

Late-gadolinium enhancement predicts appropriate device therapies in non-ischemic recipients of primary prevention implantable cardioverter-defibrillators.

Background: Better risk stratification is needed to evaluate patients with non-ischemic cardiomyopathy (NICM) for prophylactic implantable cardioverter-defibrillators (ICD). Growing evidence suggests cardiac magnetic resonance imaging (CMR) may be useful in this regard.
Objective: We aimed to determine if late-gadolinium enhancement (LGE) seen on CMR (dichotomized as none/minimal <2% vs significant ≥2%) predicts appropriate ICD therapies (primary endpoint) and/or all-cause mortality/transplant/left-ventricular assist device (LVAD) implantation (secondary endpoint) in NICM patients.
