Aortic valve open

Aortic valve open's disease overview

Heart is like a pump that takes blood to feed the body. The structure of the heart consists of two atrial and two ventricle. The atrial must be separated from the right ventricle by the three -leaf valve, the left atrium separated from the left ventricle by the mitral valve. In a heart transferred, blood from the atrial heart to ventricular and then exposed to the aorta through the aortic valve and the pulmonary artery through the pulmonary valve. The long -term valve valve disease will cause hemodynamic changes and lead to heart failure. This article will refer to the aortic valve.

Normally, after the blood flow is pumped into the aorta, the aortic valve will close to prevent the blood flow back to the heart chamber. The aortic valve is a condition that the valve is not closed, causing the blood to bounce back to the left ventricle, the consequence reduces the supply of heart and the left ventricular volume. Aortic valve opened consists of two types of expedition and chronic openings.

Causes of Aortic valve open's disease

Causes of aortic valve is different depending on the type

Acute aortic valve
  • Infections of infections

    • Aortic separation

  • Trauma damages valve leaves: after acceleration or chest injury
  • After the procedure intervention: complications of the skin aortic valve (Tavi)
    • chronic aortic valve
  • In developing countries, the most common cause of aortic valve is low valve lesions (low. heart)
  • In developed countries, the common causes are: Aortic root relaxation, valve aortic valve disease, valve calcification
  • In addition, it is possible to encounter the owner in patients with genetic diseases such as: Marfan syndrome, Ehler-danlos syndrome, ..

    • Symptoms of Aortic valve open's disease

    Aortic valve is open: The manifestations include: severe shortness of breath, acute pulmonary edema may shock. In addition, the patient also has manifestations of the cause: severe chest pain if the cause is aortic separation, signs of infection in endocarditis chronic aortic valve:
  • usually does not cause symptoms for a long time, until the heart function decreases. Patients often go to the doctor when there are signs:
  • Difficulty breathing, exertion when exertion, having shortness of breath at night

    • Chest pain due to a decrease in coronary perfusion, even if the coronary artery of the patient is normal. Chest pain can occur at night when the heart rate is slower, the blood pressure decreases, the open current volume increases due to reducing coronary perfusion.

  • legs
  • Examination can see the diastolic blow in the aortic valve, ERT-Botkin drive
  • Deep submerged circuit (called Corrigan circuit)
  • The big difference between systolic and diastolic blood pressure

    • People at risk for Aortic valve open's disease

  • Elderly

    • congenital heart treatment, two -leaf aortic valve

    Hypertension

    History of rheumatism

    Genetic disease: Marfan syndrome, Ehler-danlos syndrome, ..

    Prevention of Aortic valve open's disease

    Control blood pressure by:

  • Strengthen exercise: at least 30 minutes a day, 5 days per week
  • Diet reduces salt, lots of green vegetables, limits animal fat and replaces vegetable oils

    • Take medication regularly

    In addition, it is necessary to thoroughly treat the respiratory tract infections, sore throat due to streptococcal because they can cause low heart leading to low valve lesions

    Diagnostic measures for Aortic valve open's disease

  • Heart doppler ultrasound: is a simple, non -invasive measure but is the main exploration to decide the treatment attitude. Based on an echocardiography, it is possible to identify the cause of the aortic valve, the level of openness, the heart function, thereby deciding on medical treatment or surgery to replace the valve
  • Electrophells: Less has a open diagnostic value but can detect arrhythmia
  • chest X-ray: rarely used for diagnosis, can detect a few indirect signs depending on the case such as wide ventricular in case of aortic separation, Big heart shadow with heart failure

    • Aortic valve open's disease treatments

    Aortic valve opened: If the expedition owner causes a normal acute heart failure, it is necessary to have emergency surgery

    Chronic aortic valve:

  • Medical: Treatment of heart failure with sympathetic beta blockers (metoprolol, bisoprolol ..), inhibitors of receptor transfer/inhibitors (Lisinopril, captopril, valsartal, losartan .. ), Aldosterone resistance (Spironolactone ..)

    • Surgery
