These drugs help prevent a heart infection called infectious endocarditis. Speak to your cardiologist for more information. </p><h2>There are small risks of complications from the procedure</h2> <p>Generally, cardiac catheterization is a fairly low-risk procedure, but it is not risk-free. The doctor will explain the risks of cardiac catheterization to you in more detail before you give your consent for the procedure. The most common risks are: </p> <h3>The catheter may break through a blood vessel</h3> <p>There is a very small risk that the catheter may break through a blood vessel or the heart wall. To reduce this risk, we use a type of X-ray called fluoroscopy to see where the catheters are at all times. </p> <p>More common complications occur with dilations of the pulmonary and aortic valves.</p> <h3>Complications from pulmonary valve dilations</h3> <p>The pulmonary valve controls the flow of blood from the heart to the pulmonary artery, which carries blood to the lungs. This valve often becomes leaky after a valve dilation. This condition is called valve incompetence. It is usually mild and can occur after surgical valvotomy as well. </p> <p>Some valves do not improve enough with a valve dilation and may need surgery.</p> <h3>Complications from aortic valve dilations</h3> <p>The aortic valve controls the flow of blood from the heart to the aorta, which carries blood to the body. When this valve is too narrow, the pressure in the heart is too high and the heart has to work too hard to pump blood. However, if the valve is expanded to get rid of all the narrowing, it will probably leak. The goal of aortic valve dilation is to make the narrowing just wide enough to reduce the pressure in the heart to safe levels, without causing a significant leak. </p> <p>The doctor chooses a balloon that is small enough that it will not get rid of all the narrowing. Then surgery can be avoided. In 2% to 3% of cases, the valve becomes very leaky, even when the right-sized balloon is used. If this happens, your child may need surgery to repair the valve. </p> <p>For general information about the risks of heart catheterization, please see <a href="/Article?contentid=59&language=English">Heart catheterization: Getting ready for the procedure</a>.</p>https://assets.aboutkidshealth.ca/akhassets/Valve_dilation_MED_ILL_EN.pngValve dilation in the heart catheterization labFalse
