Single ventricle Diagnosis

Some tests use to diagnosis for Single ventricle include:

ECG: Most patients show ventricular hypertrophy.

Chest X-ray examination: most patients want to expand video, increase or decrease pulmonary blood will depend on the availability of the pulmonary valve stenosis. Increased left atrial blood in the lung or increased atrioventricular valve insufficiency persons. Depending on other aspects of the pathological anatomy of the subtypes vary.

Cardiac catheterization and angiocardiography: moving carefully in the two-dimensional color Doppler map and among the diagnostic techniques available, the need to rely on cardiac catheterization and angiocardiography in diagnosis of single ventricle and its type, and combined malformations. The objectives of inspection should include:

1) the type of single ventricle;

2) the export of and location;

3) pulmonary aortic position and the relationship between atrium and ventricle;

4) whether obstructive pulmonary or aortic flow and its parts;

5) atrioventricular valve number, location, functional status, deviation;

6) pulmonary artery pressure and resistance;

7) ventricular function (body score and diastolic blood pressure);

8) pulmonary artery thickness, distribution or previous ring beam distortions caused by surgery;

9) deformities situation.

Although the systemic circulation and pulmonary circulation of the blood mixed in a single ventricle, but as a result of intracardiac blood flow situation is different, should not conclude that the pulmonary artery and aortic oxygen saturation the situation is exactly the same, so as to accurately calculate the pulmonary circulation and systemic resistance, were determined to be the two artery oxygen saturation and pressure.

Echocardiography: two-dimensional ultrasound imaging has essentially replaced invasive cardiac catheterization for patients with single ventricle of the various aspects of observation and analysis. Such as basic anatomy of heart, the relationship between the great arteries, accompanied by heart defects, pulmonary stenosis and ventricular export department or of such two-dimensional echocardiography and understanding can be observed. A new Doppler technique could be of pulmonary stenosis, ventricular output of the Department of obstruction and atrioventricular valve insufficiency, such as the quantitative determination of the extent. Echocardiographic detection techniques to the understanding of atrioventricular valve morphology, and deviation from the saddle and so on are better than angiography.
