Presentation
We report here the first and a rarest presentation of the AMVT in a 19-year old female patient diagnosed to have double outlet right ventricle, ventricular septal defect (VSD), infundibular stenosis and congenital mitral stenosis (MS). [ncbi.nlm.nih.gov]

- Atrial Septal Defect
A small atrial septal defect was found at follow up cardiac catheterisation and angiography. Balloon dilatation of the mitral valve is a reasonable alternative to surgical treatment for typical congenital mitral stenosis even in young children. [ncbi.nlm.nih.gov]

In the patient with Shone's syndrome, nonetheless, palliation was achieved by balloon angioplasty of the aortic coarctation and by creation of an atrial septal defect. [cambridge.org]

Cardiovascular
- Diastolic Murmur
Cardiac auscultation: murmur • low-pitched diastolic rumble that is most prominent at the apex. • Although the intensity of the diastolic murmur does not correlate with the severity of the stenosis, the duration of the murmur is helpful since it reflects [slideshare.net]
Diastolic murmurs that may coexist with the MS murmur are: Early diastolic murmur of coexisting aortic regurgitation (AR), which may be conducted to the apex Graham Steell murmur (a soft decrescendo diastolic murmur heard best along the left sternal border [merckmanuals.com]
murmurs, occurring together or individually, heard loudest at the apex; and (3) electrocardiographic and roentgenologic evidence of enlargement of left atrium or left and right atria in combination, and hypertrophy of the right ventricle. [pediatrics.aappublications.org]
Diastolic Murmurs - Mitral Stenosis You are listening to a typical example of the murmur produced by mitral valve stenosis. As opposed to aortic regurgitation, mitral stenosis has a female preponderance, with the female:male ratio being about 2:1. [med.ucla.edu]
There is a low frequency mid to late diastolic murmur loudest at the apex, which is accentuated on expiration. The presence of mitral regurgitation should always be sought. [bcm.edu]
- Tachycardia
Pre medication • To decrease anxiety & any associated likelihood of adverse circulatory responses produced by tachycardia Class Drug Dose (mg/kg) Route BZPs Diazepam 0.1-0.15 PO, IM Lorazepam 0.03-0.06 PO, IM Midazolam 0.03-0.07 IM Opioids Morphine 0.2 [slideshare.net]
This elevates the left atrial pressure which, in turn, raises pulmonary venous and capillary pressure leading to bouts of DYSPNEA and TACHYCARDIA during physical exertion. RHEUMATIC FEVER is its primary cause. [fpnotebook.com]

Mildly symptomatic patients usually respond to diuretics and, if sinus tachycardia or atrial fibrillation is present, to beta-blockers or calcium channel blockers for rate control. [merckmanuals.com]
Many patients experience symptoms only when the heart rate is elevated, as tachycardia decreases diastolic filling time significantly. [healio.com]
- Cardiomegaly
CXR: Moderate to severe stenosis is manifested by mild cardiomegaly with pulmonary venous congestion and left atrial enlargement. [bcm.edu]

Eventually, the RV fails, which manifests as hepatomegaly and/or ascites, edema of the extremities, and cardiomegaly on radiography. [emedicine.medscape.com]
Chest radiograph showed cardiomegaly with prominent pulmonary artery and left atrial shadows. Electrocardiography showed left atrial dilatation with prominent right ventricular forces. Echocardiography showed severe congenital mitral valve stenosis. [jscisociety.com]

The most common finding is left atrial enlargement (P mitrale), but this finding disappears if the patient enters atrial fibrillation. Right heart strain may produce findings of right axis deviation and right ventricular hypertrophy on ECG. [healio.com]
Treatment
Clinical trials often give patients access to leading-edge treatments that are not yet widely available. [utswmedicine.org]
Many children with congenital heart defects don't need treatment, but others do. Treatment can include medicines, catheter procedures, surgery, and heart transplants. [icdlist.com]

Prognosis
CONCLUSIONS: Patients with supramitral ring constitute a subset of patients with congenital mitral stenosis who have a relatively good prognosis. [ncbi.nlm.nih.gov]
This technology is particularly suited for congenital heart disease in which there is a clear need for more clear and accurate delineation of the congenital heart defects from a 3-dimensional perspective for diagnosis, assessment, and prognosis of these [books.google.de]
Prognosis Untreated newborns with severe MS have a grim prognosis. Surgical intervention is ideally avoided for as long as possible. [emedicine.medscape.com]
The prognosis is much improved in patients who undergo surgical or percutaneous relief of valve obstruction. [ 1 ] However, life expectancy is still shortened compared with that expected for age, largely because of the complications of mitral stenosis [patient.info]
Etiology
Etiology In addition to being a sequela of rheumatic fever, which is the most common cause world-wide, there are numerous other causes 2-4 : mitral annular calcification with leaflet involvement an age-related cause congenital mitral stenosis infective [radiopaedia.org]
Etiology Most commonly due to rheumatic fever Autoimmune diseases: systemic lupus erythematosus, rheumatoid arthritis Rare inherited metabolic diseases: mucopolysaccharidoses of the Hunter-Hurler phenotype, Fabry disease Congenital Some conditions may [amboss.com]
Other uncommon etiologies include congenital stenosis of the mitral valve or age-related calcification. Overview Stenosis of the mitral valve considerably increases the resistance to blood flow between the left atrium and the left ventricle. [pathwaymedicine.org]
Etiology The etiology of congenital MS remains unknown. However, prevalence of MS in offspring of family members (especially the mother) with left ventricular outflow tract obstruction is increased. [emedicine.medscape.com]

Prevention
Prevention Follow your provider's recommendations for treating conditions that can cause valve disease. Treat strep infections promptly to prevent rheumatic fever. Tell your provider if you have a family history of congenital heart diseases. [mountsinai.org]
Cardiac rehabilitation is a critical component of recovery and can prevent future heart disease. [utswmedicine.org]

Once the left ventricle is filled it contracts, to pump the blood out to the body — and the mitral valve closes to prevent the blood from going backwards into the left atrium. [verywell.com]
