Ms. Liu had a headache for several years, and there was no abnormality in multiple examinations. Finally, under the advice of the doctors of Hunan Women and Children's Hospital, sonographic examination of the right heart found a large number of microbubbles in the left heart, and it was judged that the cause of the headache may be patent foramen ovale, and the headache disappeared after interventional closure.
1. What is right heart sonography?
Right heart sonography is a technique in which an acoustic contrast agent is injected through the peripheral vein during echocardiographic imaging to enhance the development of the right heart system. At present, the commonly used contrast agent is "normal saline + air + own blood (8ml: 1ml: 1ml)".
2. What are the indications for right heart sonography?
Screening for cardiac disease suspected of a left-to-right or right-to-left shunt, such as patent foramen ovale;
Diagnosis of congenital vascular anomalies, such as left superior vena cava, pulmonary arteriovenous fistula, etc.;
Evaluate the diameter of the right heart chamber, endocardial boundary contour, ventricular wall thickness, presence of mass, valvular regurgitation, etc.;
Find a cause for hypoxia.
3. What is the safety of right heart sonography?
There is no X-ray radiation, no drugs other than saline, and there is no risk of allergic reactions.
There are few adverse reactions, and a very small number of patients may have respiratory symptoms such as cough and dyspnea, or facial flushing, headache, local erythema, rash, fever, etc., which generally last for a short time and have no sequelae.
4. What do I need to prepare for right heart sonography?
No special preparation. During the examination, it is necessary to cooperate with the doctor to do Valsalva maneuvers and other maneuvers to increase the right atrial pressure and fully show the microbubbles of the right-to-left shunt.
summary
Right heart sonography is a "scary" sounding and seemingly "scary" ultrasound procedure, which is a simple and effective test for patients with related diseases.
