Aortic insufficiency. A result of intermittent migration of aortic valve prosthesis poppet
D. Kunstadt, A. Adeyemo and R. H. Clauss
A bizarre mechanism of aortic valve incompetence was observed when the
occluder of a Braunwald-Cutter aortic valve prosthesis decreased in
diameter, volume, and weight, and from time to time fell into the left
ventricle. The patient's symptoms were palpitation, coughing, chocking
sensations, and fright. An operation disclosed a small, smooth ball with
disrupted cloth on all the struts. The residual torn mesh was removed, and
the ball was replaced.
