According to the American Heart Association (AHA), Aortic Stenosis is a common and serious valve problem. The risk group is not limited to the elderly and patients with cardiovascular disease. Congenital defects and valve calcification can also be a factor. This article discusses the symptoms and treatment of aortic stenosis.

Aortic stenosis fear asymptomatic heart failure high risk

The so-called aortic valve stenosis, as the name suggests, refers to the narrowing or obstruction of the aortic valve of the heart, which causes the blood to be unable to output and flow normally, weakening the functioning of the myocardial muscle. Legionful words, fear of causing serious heart problems. Aortic stenosis may be asymptomatic in the early stages, and the incubation period may last for several years, and when symptoms begin to emerge, they often become severe and affect the patient’s daily life. Particular features include chest pain, fatigue with force, fainting, dyspnea, angina pectoris, palpitations and heart murmur.

Aortic stenosis is the most common heart valve disease in developed countries, affecting about 2% of the population over 65 years of age. For symptomatic patients without surgery, the mortality rate is about 50% in 5 years and 90% in 10 years

Due to the stenosis of the aortic valve, the left ventricle muscles may be thickened in order to pump blood into the aorta, and the coarse ventricle muscles take up more space. Limits blood flow and increases the risk of heart failure. Other complications include organ bleeding and thrombosis, heart infections, stroke, hypertension, atrial tremor, arrhythmia, etc.

Drug assisted improvement reduces the threat of aortic stenosis

Some patients with aortic stenosis may only have decreased physical strength but no other obvious symptoms, so it is important to have a thorough diagnosis and examination. According to Mayo Medical School studies, a physician or cardiologist first detects the patient’s heart murmur, followed by a transthoracic heart ultrasound ( Transthoracic Echocardiography (TTE) further detects the state of the pulse valve, calcification and operation of the left ventricle.

Depending on each patient’s situation, other diagnostic methods may also be considered, including electrocardiogram (ECG), cardiac computed tomography (CT scan), MRI, TEE, X-ray, motion examination, pressure detection and cardiac catheterization.

Doppler echocardiography is recommended for asymptomatic patients, with mild aortic stenosis. ~ 1 test in 5 years; 1 test for moderate aortic stenosis in 1 to 2 years; 1 test for severe aortic stenosis at least once every 6 to 12 months.

Regardless of obvious symptoms, mild or severe, patients should follow doctor’s instructions to do regular physical tests and lifestyle adjustments, especially in severe aortic valve stenosis, competitive exercise and strenuous activity are prohibited. People with other heart disease should quit smoking and test for cholesterol. This is to exclude other external factors that affect the diagnosis of the disease and choose the most appropriate treatment for the patient. In addition, while medication has no effect on aortic stenosis, it can help improve other physical problems and reduce heart burdens such as antibiotics, antiarrhythmics, anticoagulants, and hypotension drugs.

Different risk groups for thoracotomy and TAVR

According to the medical condition and physicians, patients may need surgical repair or direct replacement of the aortic valve. According to the Taipei Veteran General Hospital, Aortic Valve Replacement (AVR) can be divided into three types: Traditional Chest Opening, Minimally Invasive Surgery, and Transcatheter Aortic Valve Replacement (TAVR).

Generally speaking, thoracic surgery is a more traditional and high-risk procedure. Physicians remove blocked valves and use Tissue valves such as cattle, pigs, or human health. Valve replacement. If a patient chooses mechanical valves, it is necessary to rely on anticoagulants to sustain their lives, so be sure to discuss with your doctor before surgery. The risk of the valve to be used, the appropriateness of the valve, and the duration of recovery.

In patients with a high risk of complications, TAVR surgery is recommended because it is less invasive. With a catheter, the replacement valve is placed in the patient’s chest or leg and directed to the heart, then the balloon tied to the catheter swell, so that the valve is large, and the catheter is removed.

High surgical success rate

Patients and their families need to know that aortic valve replacement has a very high success rate and that recovery after surgery is generally optimistic, but depending on the duration of the patient’s condition, the degree of heart injury, and complications, THE recovery situation is still different.

For people who do not suffer from congenital defect, a healthy lifestyle is a great way to prevent diseases such as regular exercise, no smoking, less Alcohol consumption, low saturated fat diet, oral hygiene, etc. If you experience any abnormal physical problems, especially severe sore throat, please consult a doctor as soon as possible.
