Subaortic stenosis caused by two discrete membranes.
نویسندگان
چکیده
A case of subaortic stenosis caused by two discrete membranes is presented. Following demonstration of the two distinct sites of obstruction by intraventricular pressure gradients and angiocardiogram, the two membranes were excised through a transaortic approach. The importance of being aware of the occurrence of this rare anomaly is stressed, and its surgical implications are discussed.

Mechanism of early systolic closure of the aortic valve in discrete membranous subaortic stenosis.
The mechanism of the apparent early closure of the aortic valve in patients with discrete membranous subaortic stenosis was studied. Discrete membranous subaortic stenosis was simulated in vitro to assess the fluid dynamic characteristics in the region of the aortic valve that may be responsible for the early closure. In the presence of a simulated fixed membranous subaortic obstruction, early ...

BACKGROUND Transluminal balloon tearing of the membrane in a thin discrete subaortic stenosis is an alternative to membrane surgical resection. However, the long-term outcome of patients with isolated thin discrete subaortic stenosis treated by transluminal balloon tearing remains unknown. METHODS AND RESULTS This 25-year study describes findings from 76 patients with isolated thin discrete s...
متن کاملLeft ventricular outflow tract obstruction defined by active three-dimensional echocardiography using rotational transthoracic acquisition.
A rotational data acquisition system was used to create three-dimensional images from thoracic and subxiphoid echocardiographic windows in children with various types of subaortic stenosis. Thirteen patients, ranging in age from 2 days to 17 years, were examined. Subaortic obstruction was caused by a discrete fibrous ridge in six patients, hypertrophic cardiomyopathy in two patients, subaortic ...
