Diagnosis of tricuspid insufficiency by non invasive methods.

Abstract

The diagnosis of tricuspid insufficiency was first made at the end of last century, based on clinical signs. Graphic tracings of the venous system were soon recorded and were demonstrated useful in the forties and fifties. New methods involving invasive procedure or expensive instrumentation have been described in the last twenty years. The present study was made in order to re-examine the value of the non-invasive, graphic methods, which would assure a simple and inexpensive study for these patients.
