A case report of myocarditis masquerading as hypertrophic cardiomyopathy.

We report the case of a 16-year-old girl diagnosed with myocarditis, although initial echocardiographic imaging was consistent with hypertrophic cardiomyopathy (HCM). The diagnosis of myocarditis was made with the findings of troponin elevation, presence of influenza A, and a more characteristic electrocardiogram. She eventually made a full recovery.

Decellularized Bovine Pericardial Mitral Valve in a Neonatal Marfan Patient.

Mitral valve construction using decellularized bovine pericardium is a new procedure. A 10-month-old infant with neonatal Marfan syndrome underwent mitral valve replacement due to severe mitral regurgitation with a cylinder valve constructed from decellularized bovine pericardium. Nineteen months postoperatively the patient is clinically well with trivial mitral regurgitation, mild stenosis, and without need for anticoagulation.

Pediatric marginal donor hearts: Trends in US national use, 2005-2014.

Pediatric patients awaiting heart transplant face high mortality rates due to donor organ shortages, including non-use of marginal donor hearts. We examined national trends in pediatric marginal donor heart use over time. UNOS data were queried for heart donors <18 years from 2005 to 2014.
