heart valve dilation

The role of the membrane in the heart's never-ending blood circulation is normal and critical: the valve is the equivalent of a guard, preventing blood from flowing back to the ventricle that has just left. Between the atrium and the ventricle, there is a valve between the ventricle and the blood vessels that leave the ventricle. After the blood flows, the valve closes and sends out the heartbeat we hear on the TV. The most common valve problem is mitral valve prolapse. Treatment of diseases: aortic stenosis mitral stenosis Indication 1, mitral stenosis: If the valve leaflets are good, only adhesion junction or mild subvalvular damage, can be achieved by closed dilatation or direct vision. If the valve is calcified or funnel-like changes, a valve replacement procedure is required. 2, aortic stenosis: congenital aortic stenosis can often be performed in adolescence during direct surgery. 5. Pulmonary valve stenosis. Contraindications 1. The rheumatic activity is not controlled or controlled for less than 3 months; 2. Heart failure with myocardial ischemic damage, such as advanced patients with aortic stenosis, improved cardiac function, still seeking surgery; 3. Patients with liver or kidney function or general condition who are unable to undergo surgery; 4. Patients with bacterial endocarditis have developed sepsis and multiple infections are not suitable for surgery. Preoperative preparation (1) X-ray examination: the root of the ascending aorta often shows a stenosis and a dilatation. The severe stenosis almost has aortic valve calcification and left ventricular enlargement. (2) ECG examination: left ventricular hypertrophy with strain, sometimes left atrial enlargement. (3) echocardiogram examination: the aortic valve opening amplitude is reduced (<1.5cm), the opening speed is slowed, the left ventricular wall is thickened, the aortic wall may be thickened, and the ascending and descending speed is slowed down. (4) Cardiac catheterization: great accuracy in the identification of moderate to severe stenosis. complication Such as heart failure, severe arrhythmia, subacute bacterial endocarditis (unexplained fever, progressive anemia, hematuria, splenomegaly and skin bleeding points, should pay attention to this disease), arterial embolism (atrial thrombus, blockage of the brain Arteries can cause hemiplegia; occlusion of the pulmonary artery can cause chest pain, dyspnea and hemoptysis; occlusion of the renal artery can cause hematuria, etc.) should be promptly sent to hospital for treatment.
