Abstract

Hemodynamic and angiographic findings are described in a 27-year-old patient, who had undergone surgical operation for subvalvular membranous aortic stenosis. Left ventriculography revealed persistence or regrowth of the subvalvular fibrous ring, and hemodynamic data revealed associated dynamic obstruction of the left ventricular outflow tract. The authors emphasize the importance of uncovering associated dynamic obstruction by provocative maneuvers and use of Beta blockers.
