- Plethora
The chest skiagram in posteroanterior view revealed a cardiothoracic ratio of 0.6 and pulmonary plethora. [heartviews.org]
- Camping
A 14-year-old, adolescent male attended a routine rural health camp for complaints of increasing effort intolerance for the last 1-year and was referred to Cardiology Department for further evaluation. [heartviews.org]
Cardiovascular
- Diastolic Murmur
There is a diastolic murmur in 65% due to cusp thickening or eddy currents. X-rays show that the ascending aorta is not dilated and calcification of the valve is absent, while echocardiography (ECG) reveals severe LV hypertrophy. [radcliffecardiology.com]
murmurs are found in case of aortic- or mitral insufficiency. [slideshare.net]
Cardiac auscultation revealed normal first heart sound, a loud pulmonary component of second heart sound, a grade 4 pansystolic murmur along the left parasternal border and a grade 3 mid diastolic murmur over the mitral area. [heartviews.org]
Physical examination revealed a harsh systolic murmur at the base and 3/6 diastolic murmur at the left sternal border. He underwent TTE examination. [clinmedjournals.org]
Exercise intolerance, combined with a pansystolic murmur at the apex, with or without a mid-diastolic murmur, are the cardinal clinical features. LABORATORY INVESTIGATIONS ECG. [fqz301.brinkster.net]
- Ejection Murmur
She had an ejection murmur at the left sternal border. A chest radiograph showed cardiomegaly and the ECG showed left ventricular hypertrophy with a strain pattern. [heart.bmj.com]
Diagnosis Diagnostic evaluation is performed in children with a characteristic systolic ejection murmur. Echocardiography allows diagnosis and determines the level(s) of obstruction. [mhmedical.com]
Physical examination ) An ejection click, the loudness of which varies with respiration, and a harsh systolic ejection murmur are present at the upper left sternal border. ) In moderately severe stenosis, a thrill and right ventricular heave are palpable [elearning.sumdu.edu.ua]
An ejection systolic murmur heard at the upper left sternal border and well transmitted to the axillae and back is most common. There is no pulmonary ejection click. [fqz301.brinkster.net]
- Mid-Diastolic Murmur
Cardiac auscultation revealed normal first heart sound, a loud pulmonary component of second heart sound, a grade 4 pansystolic murmur along the left parasternal border and a grade 3 mid diastolic murmur over the mitral area. [heartviews.org]
Exercise intolerance, combined with a pansystolic murmur at the apex, with or without a mid-diastolic murmur, are the cardinal clinical features. LABORATORY INVESTIGATIONS ECG. [fqz301.brinkster.net]
Psychiatrical
- Suggestibility
A special focus has been placed on noninvasive imaging techniques, normative blood pressure standards, suggested approaches to pediatric hypertension, detection and management of lipid abnormalities as recommended by the Expert Panel, pediatric arrhythmias [books.google.ro]
Planimetry of 3D rendered orifice allowed an estimation of the residual orifice area of the membrane, suggesting a severe obstruction at subaortic level (0.5 cm2) After positioning the cropping plane in the aortic root, at the tips of the aortic cusps [3decho360.com]
In general, asymmetry of the aortic leaflets suggests congenital deformation. In equivocal cases, multiplane TEE is usually diagnostic (B->;B; Fig. 13-61). [78stepshealth.us]
Our data suggest that relief of subaortic obstruction is more favorable in the thin, membranous DDS. [eurekamag.com]
Workup
Two-dimensional (2D) echocardiography with color Doppler imaging is the current modality of choice to establish the diagnosis of SAS (see Workup). [emedicine.medscape.com]
Blocks
- Right Bundle Branch Block
Left anterior hemiblock is found in older patients and reveals severe myocardial disorder associated with excessive dysplastic muscle in younger patients; right bundle branch block occurs in about 3% of the patients. [slideshare.net]
Right bundle branch block is present in up to 95% of cases [ 36 ] and the right bundle itself might be abnormally located [ 6 ] The AV node is usually located in the triangle of Koch [ 32 ]; however, there is often discontinuity of the central fibrous [omicsonline.org]
Treatment
Emphasizes the treatment of corrected congenital heart disease for coverage of the clinical management of cardiac problems in the adolescent and young adult. [books.google.ro]
Surgical resection of the fibrous ridge with myomectomy is the treatment of choice. [clinmedjournals.org]
Every topic and chapter has been revised and updated to reflect the latest medical and surgical treatments for all congenital and acquired heart diseases. New surgical approaches, including hybrid procedures, have been updated. [books.google.com]

Severity of mitral valve obstruction correlates with poor long-term prognosis. [heartviews.org]
Right-to-left commissures have worse prognosis in bicuspid aortic than anteroposterior commissures in developing aortic stenosis. Also eccentric orifices have worse prognosis than central orifices in developing aortic stenosis. [pedcard.rush.edu]
[…] variety of congenital lesions including atrial and ventricular septal defect, pulmonic stenosis, transposition, tetralogy of Fallot, hypoplastic left heart, Ebstein's anomaly, and tricuspid atresia.621 Prenatal detection of these lesions may improve prognosis [78stepshealth.us]
Prognosis Although natural history studies have not delineated the annual mortality rate, 2-10% of sudden deaths are reported in untreated individuals with severe left ventricular outflow tract (LVOT) obstruction, including subvalvar aortic stenosis [emedicine.medscape.com]
Etiology
Etiology The rarity of fixed subaortic stenosis in newborns and its absence in the developing heart, its progressive and probably acquired nature have been the subject of several studies (18). [slideshare.net]

Interaction of genetic predisposition and morphologically deformed long and narrow LVOT cause rheological abnormalities and increased shear stress in the region of subaortic stenosis and seem to be the main etiological factor alongwith poorly defined [japi.org]

Epidemiology
Epidemiology Left ventricular outflow tract obstruction (LVOTO) occurs in 2.8 of 10,000 live births, accounting for 3 to 6 percent of congenital heart defects. [mhmedical.com]
However, the Newfoundland dog has been shown to experience an increased incidence of subaortic membranes, which may in part be secondary to inbreeding and is consistent with an autosomal inheritance. [10] Epidemiology The approximate incidence of congenital [emedicine.medscape.com]
Epidemiologic studies suggest that these defects account for nearly 30% (range, 16%–50%) of all cases ( 47,48 ). Communications at the ventricular level can be found in isolation or may be seen in the context of other structural malformations. [journals.lww.com]
Pathophysiology
Pathophysiology Rare in infancy, subaortic stenosis may present as distinct fibromuscular stenosis, or as hypertrophic obstructive cardiomyopathy (HOCM). [chw.org]
Pathophysiology. To maintain cardiac output, right ventricular pressure rises. In severe stenosis, right ventricular end-diastolic pressure may also increase. [elearning.sumdu.edu.ua]
Pathophysiology Obstruction at any level causes increased left ventricular systolic pressure and wall stress and consequent left ventricular hypertrophy. Left ventricular hypertrophy produces subendocardial ischemia and diastolic dysfunction. [mhmedical.com]

Prevention
Cardiology is a rapidly changing and expanding field with management protocols changing regularly and newer categories of treatment options being discovered, with greater emphasis on the prevention of cardiovascular diseases. [books.google.ro]
The use of intraoperative TEE helps to detect the location and extension of the resection and thus to prevent a residual gradient from remaining. As a result, surgery-related heart block and iatrogenic VSD due to operations can be prevented. [tgkdc.dergisi.org]

Early surgical repair of SAS has been advocated to prevent rapid progression of LVOTO. A significant LV-aortic mean gradient, ├óÔÇ░─ä30mmHg in children and ├óÔÇ░─ä50mmHg in adults, requires surgery. SAS has a progressive nature in adult patients. [radcliffecardiology.com]
