    A Potential Oligogenic Etiology of Hypertrophic Cardiomyopathy, A Classic Single Gene Disorder.
    Circ Res 2017 Feb 21. Epub 2017 Feb 21.
    Center for Cardiovascular Genetics, University of Texas Health Sciences Center at Houston
    Rationale: Hypertrophic cardiomyopathy (HCM) is a prototypic single gene disease caused mainly by mutations in genes encoding sarcomere proteins. Despite the remarkable advances, the causal genes in about 40% of the HCM cases remain unknown, typically in small families and sporadic cases, wherein co-segregation could not be established. Objective: To test the hypothesis that the "missing causal genes" in HCM is, in part, because of an oligogenic etiology, wherein the pathogenic variants do not co-segregate with the phenotype.

    Robotic trans-atrial and trans-mitral ventricular septal resection.
    Ann Cardiothorac Surg 2017 Jan;6(1):54-59
    Department of Cardiovascular Sciences, East Carolina Heart Institute, East Carolina University & Vidant Medical Center, Greenville, North Carolina, USA.
    Localized ventricular septal hypertrophy, also known as idiopathic hypertrophic subaortic stenosis or idiopathic hypertrophic subaortic septal obstruction (IHSS), can create severe ventricular outflow obstruction. This often results in a high sub-aortic pressure gradient with potentially lethal symptoms. In 1960, Braunwald described the hemodynamic characteristics of IHSS, and thereafter, Morrow developed a trans-aortic approach to resect a large part of the ventricular septum, enlarging the outflow tract.

    Morphotype-Dependent Flow Characteristics in Bicuspid Aortic Valve Ascending Aortas: A Benchtop Particle Image Velocimetry Study.
    Front Physiol 2017 1;8:44. Epub 2017 Feb 1.
    Department of Mechanical and Materials Engineering, Wright State University Dayton, OH, USA.
    The bicuspid aortic valve (BAV) is a major risk factor for secondary aortopathy such as aortic dilation. The heterogeneous BAV morphotypes [left-right-coronary cusp fusion (LR), right-non-coronary cusp fusion (RN), and left-non-coronary cusp fusion (LN)] are associated with different dilation patterns, suggesting a role for hemodynamics in BAV aortopathogenesis. However, assessment of this theory is still hampered by the limited knowledge of the hemodynamic abnormalities generated by the distinct BAV morphotypes. Read More
