Fixed subaortic stenosis: anatomical spectrum and nature of progression.
Retrospective echocardiographic review identified 58 consecutive infants and children with fixed subaortic stenosis. Mean (SD) age at diagnosis was 4.8 (3.6) years (range two days to 14.7 years), and diagnosis occurred in infancy in eight. Associated cardiac abnormalities were present in 41 (71%) whereas fixed subaortic stenosis was an isolated lesion in 17 (29%). Four types of fixed subaortic ...
متن کاملMorphology of left ventricular outflow tract structures in patients with subaortic stenosis and a ventricular septal defect.
OBJECTIVE To compare the incidence and prognosis of subaortic stenosis associated with a ventricular septal defect and to define the morphological basis of subaortic stenosis. DESIGN Presentation and follow up data on 202 patients with subaortic stenosis seen at the Royal Liverpool Children's Hospital between 1 January 1960 and 31 December 1991 were reviewed. Survivors were traced to assess t...
متن کامل[Subaortic stenosis more than twenty years after surgical repair of a partial atrial septal defect in an adult].
Subaortic stenosis after surgical correction of a partial atrioventricular septal defect is uncommon. When it occurs, it is usually diagnosed 6-8 years after early surgical repair in childhood. We present a female patient who underwent mitral valve cleft repair and closure of a partial atrial septal defect with a Teflon patch at the age of 48 years. Twenty-two years later, she presented with se...
متن کاملSystolic time intervals in valvular aortic stenosis and idiopathic hypertrophic subaortic stenosis.
Corrected systolic time intervals of the left ventricle: the interval between the onset of the Q wave and the first heart sound (Q-MI), isovolumic contraction time (IVCT), and left ventricular ejection time (LVET) have been measured by noninvasive techniques in 26 patients with valvular aortic stenosis and in 25 patients with idiopathic hypertrophic subaortic stenosis. The results were compared...

متن کاملReoperation after relief of congenital subaortic stenosis.
We read with interest the paper by Dodge-Khatami et al. [1] on risk factors for reoperation after relief of congenital subaortic stenosis. We compliment them on their extensive statistical analysis and would like to discuss their results as well as our own [2]. Preoperative left ventricular outflow tract (LVOT) gradients in their series ranged from 5 to 120 mmHg, which would lead us to question...
