Pulmonary valve st2
  • Frequent associated lesions include ventricular septal defect (VSD), pulmonary valve stenosis, and discrete subaortic stenosis. (medscape.com)
  • small arrows outline pulmonary valve stenosis (Image courtesy of R.M. Freedom, MD). (medscape.com)
Myocardial infarction1
  • We report a very rare case of endocarditis on top of discrete subaortic membrane in an adult male which was complicated by embolisation to the left anterior descending artery leading to acute anterior myocardial infarction as well as left middle cerebral artery resulting in right sided hemiparesis. (ijcimr.org)
Fibrous1
  • A type of constriction that is caused by the presence of a fibrous ring (discrete type) below the AORTIC VALVE , anywhere between the aortic valve and the MITRAL VALVE . (online-medical-dictionary.org)
Endocarditis2
  • Discrete subaortic membrane may remain silent and present lately in adult life with complications like endocarditis which might announce itself by embolic manifestations. (ijcimr.org)
  • A diagnosis of endocarditis on top of a subaortic membrane with vegetations causing both cerebral and coronary embolisation was postulated. (ijcimr.org)
Aortic valve3
  • Discrete subaortic membrane (DSM) represents a subvalvularmfibromuscular ring beneath the aortic valve [1]. (ijcimr.org)
  • A discrete subaortic membranewas found 8mm beneath the aortic valve and extending over2/3 of the circumference of the LVOT causing a peak systolicgradient of 22 mmHg (may be underestimated due to the lowEF). (ijcimr.org)
  • The presence of a stenosis (narrowing) of the aortic valve. (nih.gov)
Tract1
  • An echocardiography picture showing the subaortic membrane protruding into the left ventricular outflow tract with tiny masses on it. (ijcimr.org)
Ratio2
  • To determine if symptoms and electrocardiographic abnormalities relate to left ventricular mass, volume, and mass/volume ratio in children with aortic stenosis and/or insufficiency, we examined 42 patients (aged 11±6 years) with cross-sectional and Doppler echocardiography. (cambridge.org)
  • However, due to differences in left ventricular volume, symptoms and electrocardiographic abnormalities occurred at a higher mass/ volume ratio in pure aortic stenosis (2.7±0.6) than in combined aortic stenosis and insufficiency (1.7±0.3). (cambridge.org)
Definition1
Left1
  • When symptomatic and asymptomatic patients were compared using an unpaired Student's t-test, symptomatic patients with pure aortic stenosis and combined aortic stenosis and insufficiency had left ventricular hypertrophy and inappropriately increased mass/volume ratios. (cambridge.org)
Children1
  • Although the fact that discrete subaortic membrane is considered the second most common cause of subaortic stenosis among children accounting for 14% of cases, yet few reports are available about it in adults. (ijcimr.org)
Free1
  • the plaque can be free from stenosis but the re-established blood flow does not reach the capillary bed that is blocked by clots. (grupocorpal.com)
Patients1
  • Twenty-four patients (aged 12±6 years) had aortic stenosis and aortic insufficiency (peak gradient 36±18 mm Hg, mean gradient 19±9 mm Hg, 18 with 1−2+ aortic insufficiency and six with 3−4+ aortic insufficiency). (cambridge.org)
Left ventricular outfl1
  • We describe a rare case of an asymptomatic 20-year-old woman with mesocardia, CCTGA, and severe subvalvular pulmonic stenosis due to a ball-shaped accessory tissue in left ventricular outflow tract. (bvsalud.org)
Membranous subaortic stenosis1
  • Echocardiogram of membranous subaortic stenosis. (medscape.com)
Aortic stenosis5
  • No specific laboratory blood tests are required in the workup of subvalvar aortic stenosis (SAS). (medscape.com)
  • Go to Imaging in Aortic Stenosis for more complete information on this topic. (medscape.com)
  • Cardiac catheterization is not routinely indicated in isolated subvalvar aortic stenosis (SAS) but can be utilized for preoperative hemodynamic evaluation when associated with other congenital heart defects. (medscape.com)
  • In subvalvar aortic stenosis (SAS), even if it is mild, electrocardiography (ECG) reveals a variable degree of left ventricular hypertrophy in 50-80% of patients. (medscape.com)
  • The most commonly associated clinically significant defects include patent ductus arteriosus , VSD, and aortic stenosis. (medscape.com)
Obstruction1
  • Ventricular myxomas may cause outflow obstruction similar to that caused by subaortic or subpulmonic stenosis. (clinicalgate.com)
