title: Noninvasive right and left heart catheterization: taking the echo lab beyond an image-only laboratory.
abstract: The assessment of cardiovascular hemodynamics is an extremely important component of managing patients with cardiac diseases. For years, this has been accomplished primarily through the use of right and left heart catheters placed within the cardiac chambers. Since this is an invasive technique, it should only be used when necessary; patient discomfort, infections, and overall risks for physicians would be reduced if noninvasive methods were utilized when available. Echocardiography (echo) provides the greatest ability to determine cardiovascular hemodynamics noninvasively, but requires the utmost precision and care to avoid misinterpretation. When used correctly, echocardiographic modalities provide an even greater assessment of the cardiac patient than invasive techniques. A safer and more comprehensive interpretation is available, and thus, echo should be considered the modality of choice-the new gold standard.
