Aortoventriculoplasty after a prior posterior root enlargement (Manougian): case report.

A patient with congenital bicuspid aortic stenosis had an open commissurotomy followed 3 years later by a Manougian's operation along with an aortic valve replacement. Nine years later, due to residual aortic stenosis, a Konno's anterior root enlarging procedure with an aortic valve replacement was successfully done. Good relief of aortic and subaortic stenosis and the absence of significant gradient across the left ventricular outflow tract led us to believe that successful and effective relief could be obtained by adding a Konno-type of enlargement to a previously performed posterior enlargement procedure.
