16 Possible Causes for Multi Gated Acquisition Scan Abnormal, Pulsus Alternans

  • Cardiomyopathy

    BACKGROUND: Coronary artery fistula, first described by Krause in 1865, is an abnormal communication between the coronary artery and one of the four chambers of the heart or one of the great vessels. The communications are often congenital but may also be acquired from trauma or invasive cardiovascular[…][]

  • Dilated Cardiomyopathy

    Pulsus alternans is an infrequent, complex pathophysiologic sign often associated with severe heart failure.[] Evaluation noted pulsus alternans, with beat-to-beat alternations in aortic pulse wave amplitude, both clinically and on diagnostic studies.[] Recognition of pulsus alternans is important as it provides significant clinical information, may suggest suboptimal medical management, and may be the first warning sign[]

  • Ischemic Cardiomyopathy

    Abstract BACKGROUND Ischemic cardiomyopathy is characterized by myocyte loss, reactive cellular hypertrophy, and ventricular scarring. However, the relative contribution of these tissue and cellular processes to late failure remains to be determined. METHODS AND RESULTS Ten hearts were obtained from individuals[…][]

  • Fungal Myocarditis

    Once heart dysfunction sets in, signs of cardiac failure may manifest, such as pulmonary edema (fluid accumulation in the lungs), peripheral oedema, hypoxemia, pulsus alternans[]

  • Acute Myocarditis

    A young woman presented with fulminant heart failure. Transthoracic echocardiography revealed severe left ventricular dysfunction with a mass adjacent to the basal anterior wall, near the left ventricular outflow tract (LVOT). The cause of the acute heart failure and mass was unclear. Transesophageal[…][]

  • Alcoholic Cardiomyopathy

    Leg elevation promptly reversed the pulsus alternans, and the echocardiographic abnormality.[] Application of a small dose of glyceryl trinitrate paste (0.25 in) resulted in severe left ventricular dysfunction with the appearance of pulsus alternans in a patient with[]

  • Primary Cardiomyopathy

    Abstract Eleven patients with hypertrophic obstructive cardiomyopathy and eight patients with idiopathic congestive cardiomyopathy underwent extensive neuromuscular studies to determine if a skeletal myopathy is associated with uncomplicated primary cardiomyopathy. The clinical examination revealed peripheral[…][]

  • Toxic Myocarditis

    Myocarditis can be difficult to diagnose in the Emergency Department (ED) due to the lack of classic symptoms and the wide variation in presentations. Poor cardiac contractility is a common finding in myocarditis and can be evaluated by bedside ultrasound. To demonstrate the utility of fractional shortening[…][]

  • Lymphocytic Myocarditis

    Abstract To determine whether the heart-specific immunoreactivity associated with active myocarditis affects outcome after heart transplantation, we retrospectively analyzed the outcome of 12 patients with active lymphocytic myocarditis in their explanted native hearts identified by the Registry of the[…][]

  • Myocardial Fibrosis

    Abstract An extensive myocardial fibrosis due to progressive systemic sclerosis (PSS) was described in a 36-year-old normotensive woman without pulmonary hypertension. An electrocardiogram showed low voltage and a pseudo-infarctional pattern in leads V1 through V3. Right ventricular dilatation and generalized left[…][]
