Lipomatous hypertrophy of the interatrial septum: characterization by transesophageal and transthoracic echocardiography, magnetic resonance imaging, and computed tomography.

Lipomatous hypertrophy of the interatrial septum is a benign condition that must be distinguished from other space-occupying lesions of the atria. Patients with this disorder generally have chronic pulmonary disease and thus are difficult to image with conventional transthoracic two-dimensional echocardiography. Transesophageal echocardiography can provide high quality imaging of intracardiac structures in patients who lack adequate transthoracic echocardiographic windows as a result of pulmonary disease. This case report describes the appearance of lipomatous hypertrophy of the interatrial septum as investigated by transesophageal echocardiography.

Canadian consensus recommendations for the measurement and reporting of diastolic dysfunction by echocardiography: from the Investigators of Consensus on Diastolic Dysfunction by Echocardiography.

Abnormalities of diastolic filling are increasingly recognized as a cause of symptoms and predictors of outcome in patients with most forms of heart disease. Noninvasive assessment of diastolic filling is possible in almost all patients, but accurate evaluation must relate echocardiographic Doppler measurements to the complex physiologic and hemodynamic factors responsible for normal and abnormal filling. This evaluation has been facilitated by recent correlation of Doppler measurement of mitral and pulmonary venous inflow with hemodynamic studies. These studies have confirmed that when a careful, integrated approach is taken, Doppler flow patterns can document a progressive pattern of abnormality in many conditions. Impaired left ventricular (LV) relaxation is seen early and is recognized by a decrease in early transmitral LV filling and an increased proportion of filling during atrial contraction. As abnormalities progress, increasing LV chamber stiffness and elevated left atrial pressure lead to a "pseudonormal" filling pattern that previously has caused considerable confusion. This can be unmasked by careful evaluation of pulmonary venous inflow and the use of the Valsalva maneuver. When marked diastolic abnormalities are present, LV filling has restrictive features characterized by rapid early filling, a very stiff left ventricle with high filling pressures, and a poor prognosis. Routine measurement of indexes of diastolic filling have been hampered by uncertainty as to what should be measured, what techniques should be used, definition of normal values, and a clear method of reporting findings. This report represents the efforts of a Canadian consensus group to define a national standard for the performance and reporting of echocardiographic Doppler studies of diastolic filling.

The therapeutic aspects of acceptance.

PROBLEM: What does acceptance mean to hospitalized adolescents? METHODS: Using a phenomenological research approach, the authors asked hospitalized adolescents (N = 6) on a psychiatric unit to describe how acceptance from psychiatric-mental health nurses was experienced by them. FINDINGS: Three essential themes emerged: (a) the nurse who shows acceptance is seen as a friend, (b) acceptance generates a sense of well-being, and (c) acceptance produces feelings of comfort with the nurse. CONCLUSIONS: In acceptance, adolescents experience nurses as unique individuals who provide comfort and nurturing. This relationship connection helps adolescent clients to use their inner strength to gain a sense of well-being.
