正确的心 ventricular 血管造影术

定义

正确的心 ventricular 血管造影术 is a test that images the right chambers (atrium and ventricle) of the heart.

选择的名字

Angiography - right heart; 正确的心 ventriculography

如何执行测试

You will get a mild sedative 30 minutes before the procedure. A cardiologist will cleanse the site and numb the area with a local anesthetic. Then a catheter will be inserted into a vein in your neck, arm, or groin.

The catheter will be moved into the right side of the heart. 随着导管的推进, the doctor can record pressures from the right atrium and right ventricle.

Contrast material ("dye") is injected into the right side of the heart. It helps the cardiologist determine the size and shape of the heart's chambers and evaluate their function as well as the function of the tricuspid and pulmonary valves.

The procedure will generally last less than 1 hour but may be considerably longer.

如何准备考试

You will not be allowed to eat or drink for 6 to 8 hours before the test. The procedure takes place in the hospital. Generally, you will be admitted the morning of the procedure. However, you may need to be admitted the night before.

A health care provider will explain the procedure and its risks. 你必须签一份同意书.

考试的感觉如何

You will be given local anesthesia where the catheter is inserted. Afterward, the only thing you should feel is pressure at the site. You will not feel the catheter as it is moved through your veins into the right side of the heart. You may feel a flushing sensation or the feeling that you need to urinate as the dye is injected.

为什么要进行测试

正确的心 血管造影术 is performed to assess the blood flow through the right side of the heart.

正常的结果

正常结果包括:

• 心脏指数2.8 to 4.2 liters per minute per square meter (of body surface area)
• Pulmonary artery systolic pressure is 17 to 32 millimeters of mercury (mm Hg)
• Pulmonary artery mean pressure is 9 to 19 mm Hg
• Pulmonary diastolic pressure is 4 to 13 mm Hg
• Pulmonary capillary wedge pressure is 4 to 12 mm Hg
• Right atrial pressure is 0 to 7 mm Hg

异常结果意味着什么

异常结果可能是由于:

• Abnormal connections between the right and left side of the heart
• Abnormalities of the right atrium, such as 心房粘液瘤 (很少)
• Abnormalities of the valves on the right side of the heart
• Abnormal pressures or volumes, particularly lung problems
• Weakened pumping function of the right ventricle (this could be due to many causes)

风险

风险 of this procedure include:

• 心脏 心律失常
• 心脏压塞
• 栓塞 from blood clots at the tip of the catheter
• 心脏病
• 出血
• 感染
• 染料对肾脏造成损害
• 低血压
• Reaction to contrast dye or sedating medicines
• 中风
• 静脉或动脉外伤

注意事项

此测试可与 冠状动脉造影 还有左心导管.
