    An unusual thrombotic complication during percutaneous closure of atrial septal defect.
    (The Journal of invasive cardiology, 2009)
    A case is described where intracardiac thrombus was observed at the junction of the superior vena cava and the right atrium during attempted closure of an atrial septal defect (ASD) using a device similar in design to the Amplatzer septal occluder (Heart R atrial septal occluder). Thrombosis was likely related to the multiple attempts required when deploying the device and the attendant prolonged procedural time. The patient underwent subsequent urgent surgical closure of the ASD.

    Membranous Septal Aneurysm: An Unusual Cause for Right Ventricular Outflow Tract Obstruction in a Malaligned Ventricular Septal Defect with Aortomitral Discontinuity (Double-Outlet Right Ventricle) Associated with Visceral Heterotaxy
    (PEDIATRIC CARDIOLOGY, 2009)
    The development of a septal aneurysm in the natural history of membranous ventricular septal defects usually makes the defect hemodynamically less significant. This report describes a case of severe right ventricular outflow obstruction produced by a membranous septal aneurysm in a patient who had an anterior malaligned ventricular septal defect with aortomitral discontinuity (double-outlet right ventricle). This patient did not have pulmonary stenosis other than the dynamic obstruction produced by the septal aneurysm. In this patient, the septal aneurysm produced both favorable and unfavorable hemodynamic effects. A reduction in the size of the ventricular septal defect produced a favorable effect, whereas a right ventricular outflow obstruction led to the unfavorable situation of right ventricular hypertension and hypertrophy. The large septal aneurysm in the presence of an already compromised right ventricular outflow tract related to an anteriorly malaligned septum resulted in severe obstruction.

    Unusual coarctation-the PHACE syndrome: report of three cases.
    (Congenital heart disease, 2008)
    OBJECTIVES: To report the clinical features, nature of vasculopathy observed and the management instituted in three cases of PHACE syndrome.RESULTS: All three patients were noted to have diffuse vasculopathy and aortic arch hypoplasia in addition to aortic coarctation adding substantial surgical risk or making surgery palliative.CONCLUSION: PHACE syndrome should be considered in the differential diagnosis of aortic coarctation associated with aortic arch hypoplasia.
