I first started using the V scan myself over four years ago, and I have found this hand-held mobile device extremely useful for providing rapid and important diagnostic information at the bedside. The quality of the images of the V scan are usually of sufficiently high quality to make a useful clinical assessment. It is usually possible to make a fair assessment of systolic function of the left ventricle. I have also found that the identification of a dilated right heart has often been very useful for diagnosing massive pulmonary emboli – quite frequently when this diagnosis would not otherwise have been suspected. Valve lesions of significance are invariably pretty obvious and the images are usually adequate to identify vegetations as well. Pericardial effusion is readily detected.
