Diagnosis and treatment of aortic stenosis

The article was consulted professionally by Master, Dr. Nguyen Tung Hoan – Interventional Cardiologist – Resuscitation – Emergency Department – Share99 Nha Trang International Health Hub.

Aortic stenosis is the third-leading congenital heart defect after catheter and arterial tubes. The narrow position may be in front of the arterial tube or behind the arterial tube. Aortic stenosis is 3 times more common in male children than in females. This article will provide information on methods of diagnosing and treating aortic stenosis.

1. Diagnosis of aortic stenosis

Diagnosis of aortic stenosis when there is a clear difference between arterial pressure in the upper and lower entests; arterial pressure in the hands is sometimes up to 200 – 300 mmHg at maximum, where the arterial pressure in the legs is often not measured or greatly reduced.

Diagnostic methods of aortic stenosis include:

Chest X-ray

The shooting result may be normal, in the classic case 3 arcs can be seen in the aortic, observed in a straight-faced position. After a few years of age, more specific signs can be seen such as: rib marks, a marked increase in chest heart index.

Electrolysynth

This method helps to detect signs of increased left atathynth, however it does not allow the diagnosis of the disease.

Cardiac Doppler Ultrasound

This method is usually useful in young children, in adults it is more difficult to evaluate. On ultrasound can determine the location of the narrowing site, measure the pressure difference through the aortic waist, detect coordinated congenital abnormalities such as mitral aortic valves, blockage of the left erthway line, mitral valve stenosis… Color Doppler ultrasound and 2D ultrasound allow to determine the location and ermence of the aortic waiststenosis , especially in young children.

Aortic computer ctectry

This is the decisive means of diagnosing aortic stenosis in adults. On the film, the location, narrow edic erm, bladder resictening and coordinated lesions are identified.

Diagnostic cardiac information

This method takes instruments through the peripheral blood vessels (femoral arteries or rotational arteries) to capture the narrowing and circulation of the system. Aortic stenosis is diagnosed when the pressure difference above 10mmHg between the aortic up and down the aortic method by cardiac cone and aortic scan remains the leading method for diagnosis. However, the pressure difference does not reflect the degree of narrowing as it can be influenced by the ural 30s.

  • Nuclear resonance : Isa useful additional recording method and Doppler ultrasound can also estimate the degree of narrowing.
  • Exertion test: Signs of sysentinal hypertension may be seen in patients with aortic stenosis.

Heart ultrasound

Aortic stenosis can be diagnosed via doppler cardiac ultrasound

2. Treatment of aortic stenosis

Treatment of aortic stenosis including medical treatment, surgery or intervention

2.1. Medical treatment

Symptomatic treatment is intended to preserve the patient in preparation for intervention. Treatment of left heart failure is the most important issue. For babies, Prostaglandine E1 helps open the arterial tube which will rapidly improve clinical symptoms. Dies, Digoxin and artificial inger are other coordinated measures when really necessary. Extreme attention should be paid to renal function when taking medications for heart failure in babies. Treatment of drug hypertension in patients treated with aortic stenosis is usually not available or less effective.

2.2. Medical treatment

In dinhning intervention or surgery in the following cases:

  • Narrowing of the pressure at rest above 20mmHg: Can be assessed by the difference in entestent blood pressure on the lower entest, via ultrasound or cardiac condction.
  • There is evidence of cruisers system development.
  • Hypertension that causes is narrowing of the waist.
  • Heart failure;
  • Babies with little medical treatment.
  • Infants and young children show signs of clinical and sub-clinical heart failure.
  • Children with sysysy artery blood pressure greater than 150mmHg.
  • For other cases of aortic stenosis, surgery is systemical when the child is between 6 and 9 months old.
  • For adults, classic intervention is in place when the pressure difference crosses the aortic waist from 20 to 30mmHg. However, it is necessary to coordinate with other signs such as fibrillous heart failure,left atrocemia, difficult-to-control hypertension …
  • In case of re-narrowing the aortic waist after the intervention, it is possible to specify whether or not the balloon through the skin is accompanied by the placement of a stent. Short-term studies show fairly good results, fewer complications, but more long-term studies are still needed to confirm this problem.

Surgery

In-place intervention or surgery in cases of heart failure

2.3. Surgical or intervention options?

  • Infants and children under 4 months of age: Surgical options.
  • Children over 4 months old, under 25kg: Skin intervention or surgery depending on the experience of the treatment place and the edicty of the lesion. However, surgery is a preferred option for children under 5 years old.
  • Children over 25kg and adults: Skin intervention is preferred over surgery.

Aortic stenosis is a malformations that are prone to missed diagnosis. Blood pressure measurement and vascular arrest of both the upper and lower 30s are necessary measures in clinical examination. Surgery to treat aortic stenosis has good results. Ball narrowness should be done in conditional centers.
