Percutaneous Balloon Dilation of Discrete Subaortic Stenosis: A Futile Exercise.

Percutaneous Balloon Dilation of Discrete Subaortic Stenosis: A Futile Exercise. J Invasive Cardiol. 2017 Sep;29(9):E107-E108 Authors: Moorthy N, Ananthakrishna R, Rao DPV, Manjunath SC, Nanjappa MC Abstract Discrete subaortic stenosis (DSS) is a progressive obstruction of left ventricular outflow tract (LVOT) resulting in the development of aortic regurgitation in its natural course. Hence, early intervention is recommended. Percutaneous balloon dilation of DSS has been reported and can substantially reduce LVOT pressure gradient. The response to balloon dilation of DSS is transient and may complicate with chordal or papillary muscle rupture. Hence, balloon dilation of DSS should be discouraged.
