  • Title: Pitfalls and limitations of M-mode echocardiography.
    Author: Kotler MN, Segal BL, Mintz G, Parry WR.
    Journal: Am Heart J; 1977 Aug; 94(2):227-49. PubMed ID: 560114.
    Abstract:
    Newer diagnostic applications as well as the ability of obtaining physiologic information has resulted in a greater interest in echocardiography. As with any new technique, certain classical criteria have not been found to be as specific and diagnostic as was originally believed. This review has focused on the more important clinical applications in echocardiography. We have not attampted to discuss every single clinical entity. A critical evaluation as to the sensitivity and specificity of echocardiography in each clinical application is necessary. A thorough knowledge of the basic principles of ultrasound, a familiarity with recording devices, and a realization of the pitfalls and limitations of the technique in each cardiac disorder is essential. Hazards of echocardiographic interpretation may actually hamper its development as a diagnostic tool. Before embarking on complex and sophisticated two-dimensional echocardiography, problems with regard to technique and interpretation of M-mode echocardiography must be overcome.
