Article Synopsis
- - In a study, 7 healthy male adolescents developed acute myocarditis or myopericarditis with chest pain shortly after receiving their second dose of the Pfizer-BioNTech COVID-19 vaccine, and 5 of them had fever at the time.
- - All patients tested negative for acute COVID-19 and had no previous infections, with cardiac MRI showing signs of myocarditis, although they all recovered quickly from their symptoms.
- - The report suggests ongoing monitoring for vaccine-related adverse events, but no direct link between the vaccine and the myocarditis cases has been confirmed.
Objective: To describe the significance of aortic root distortion (AD) and/or aortic valve insufficiency (AI) during balloon angioplasty of the right ventricular outflow tract (RVOT) performed to rule out coronary artery compression prior to transcatheter pulmonary valve (TPV) implantation.
Methods: AD/AI was assessed by retrospective review of all procedural aortographies performed to evaluate coronary anatomy prior to TPV implantation. AD/AI was also reviewed in all pre-post MPV implant echocardiograms to assess for progression.
Objective: To test the hypothesis that chronic beta-blocker therapy in pediatric patients with Marfan syndrome alters the rate of aortic root dilation. Beta-blockade has been advocated as preventive therapy for Marfan syndrome based on reports indicating a decreased rate of aortic root dilation in treated patients.
Study Design: Patients with Marfan syndrome (n = 63) followed at Children's Hospital of Pittsburgh or Children's Hospital of New York-Presbyterian who had > or =18 months of echocardiographic follow-up were studied.
